Review the detail specification review item of ECSS-Q-ST-60-12C clause 7.3.11 for a microwave die: check the product level document carries every content block the programme expects, validate each specified parameter for a unit, a guaranteed limit and the measurement conditions that limit is guaranteed under, test the limits for ordering, confront each guaranteed limit with the absolute maximum rating governing it, confirm the issue, date, approval and change record hold the document under co...

Evaluate the development plan review item of ECSS-Q-ST-60-12C clause 7.3.12 for a microwave die: order the remaining activities through their dependencies, reject a circular or dangling link, roll the durations forward to the earliest finish the work allows, size the float left against the committed date, spread each activity effort across its duration to find the peak staffing demand against declared capacity, test every milestone against the earliest finish of the work it names, then close,...

Determine what an arriving bare die batch is checked for at goods inwards and what happens to it, per ECSS-Q-ST-60-12C clause 10.3: validate the arrival record, reconcile ordered against packing list against counted quantity, derive the applicable checks with the severity each carries, compute the quantity outcome rather than accept it, and walk the disposition ladder from reject through quarantine and deviation to release. Refuses an incomplete inspection record and treats an unperformed che...

Map the clause route a die-form MMIC procurement case pulls in under ECSS-Q-ST-60-12C clause 4.1: normalise the case, fire each clause area's own applicability rule and keep the reason it fired, close the routed set under the prerequisites those areas consume, order it so nothing is entered before what it depends on, and report the covered fraction with the findings an order clears first. Refuses a dependency cycle, an unknown clause key and a misspelt case flag, and reports a packaged part a...

Evaluate the carriers, seal and store conditions holding a bare die batch between delivery and assembly, per ECSS-Q-ST-60-12C clause 10.2.5: validate the arrangement, score the mechanical, moisture, electrostatic and environmental barriers, take the weakest as the protection actually given, track out-of-seal floor life in whole days, and pair every finding with the action that restores it. Refuses an unknown carrier or seal, a fractional day count and inverted store limits. Use when dies are ...

Size a microwave die procurement end to end, from wafer start to accepted delivery, under the general approach of ECSS-Q-ST-60-12C clause 10.1. Use when a buyer must decide how many wafers to start so a flight quantity still exists at the far end of the route: validate the declared stage chain against the canonical order, refuse a repeated or unknown stage, multiply the per-stage yields into a cumulative survival fraction, work the required quantity plus its contingency back to a wafer start,...

Evaluate one candidate microwave die against the detailed selection criteria of ECSS-Q-ST-60-12 clause 5.1.2. Use when a die has cleared the baseline rules and the design now has to prove it, criterion by criterion: grade gain, output power, noise figure and both return losses at the graded band edge, compare each bias rail with a derated rating rather than an absolute maximum, form the channel temperature from the dissipation and the junction-to-case path, project the Arrhenius life at that ...

Assess a candidate microwave die against the baseline selection rules of ECSS-Q-ST-60-12 clause 5.1. Use when the task is deciding which bare die may enter a microwave design at all: confirm the die comes from a controlled process reached by a traceable supply route, measure how much of the application band, case-temperature range, total-dose requirement and rated life it actually covers, separate a hard exclusion from a recoverable evidence gap, then group the candidates as eligible, eligibl...

Evaluate whether the electrical design specification written for a microwave monolithic integrated circuit states the performance, interface and operating-condition data that circuit design needs, under ECSS-Q-ST-60-12 clause 7.2.1. Use when a draft MMIC electrical specification is submitted and someone must release or hold it before circuit design starts: name the mandated parameters it omits, refuse a limit whose minimum exceeds its maximum, flag a parameter given without the unit or the te...

Size the wafer lot a flight-model MMIC die order has to start under ECSS-Q-ST-60-12C clause 4.2: grade the chosen foundry's qualification at wafer start rather than at order date, hold the batch to one wafer lot on one mask set, run the flight die count back up through assembly attrition, the destructive and validation sample draws and every screening yield stage in reverse, then turn the die starts into whole wafers and test them against the largest lot that foundry will run. Refuses a yield...

Evaluate a semiconductor process and the foundry operating it against ECSS-Q-ST-60-12 clause 5.2. Use when a microwave design has to commit to a process line: confirm the validation status, its reference document and whether it is still current, treat a process change since validation as a re-qualification trigger rather than a note, derive the usable frequency from the gate length and technology, weigh breakdown voltage and the offered passive elements against the circuit need, form the proc...

Size the receipt testing arrangement for an arriving die lot and dispose of the lot on what the sample shows, per ECSS-Q-ST-60-12C clause 10.3.1: band the lot size to a code letter, draw the sample for the inspection level, derive the acceptance number by whole-number arithmetic, adjust it for tightened or reduced severity, accept or reject against the observed defectives, and apply the switching rules that set the severity for the next lot. Refuses a defective count larger than its own sampl...

Validate a drawn MMIC mask layout against the foundry rule deck under ECSS-Q-ST-60-12C clause 7.2.11: run minimum drawn width, same-layer spacing between differing nets and inner-to-outer enclosure over every rectangle, then the electrical checks that each declared net is drawn, each drawn net is declared, no node is left floating and the narrowest metal carries the net current. Use when a layout database is handed over and the run has to say clean, waived or failed. Refuses a duplicate shape...

Review the physical layout a device design review is presented with and decide whether the item closes or carries an action. Use when an ECSS-Q-ST-60-12C clause 7.3.7 layout review item has to reach a verdict: confirm every required drawing kind is present, released and standing at the design baseline issue rather than above or below it; take each interface pad as placed once, inside the outline keep-out, with the closest pad pair no tighter than the declared minimum pitch; and carry a residu...

Verify that the absolute maximum ratings declared for a MMIC die sit below the measured degradation onset by the required factor, that every rating is backed by a robustness demonstration driven at or above its own boundary on a large enough sample, and that worst-case application stress stays inside the derated envelope, per ECSS-Q-ST-60-12C clause 7.2.9. Use when a die specification proposes maximum ratings and the evidence file has to accept or hold them. Refuses a non-positive boundary, a...

Determine the lowest die quality level a space equipment build may accept under ECSS-Q-ST-60-12C clause 4.3: place the application on the quality ladder from equipment criticality, mission duration, radiation exposure and single-point-failure standing, compare the offered die against that floor, and where it sits below, derive the rung-by-rung upgrade actions — added screening, lot validation testing, destructive analysis — that close the gap, or refuse the die when no upgrade route reaches t...

Assess how a monolithic microwave circuit is conceived and refined against the design principles of ECSS-Q-ST-60-12C clause 7.1: turn each specification line into a parametric margin in standard deviations of process spread and a predicted yield, combine those lines into one figure, grade channel temperature, metal current density and RF power density against derated rather than absolute limits, weigh proven library cells against novel structures needing a test vehicle, and require design-rul...

Evaluate an MMIC design-review programme before fabrication release. Use when the question is whether the microwave circuit design cleared every formal checkpoint ECSS-Q-ST-60-12C clause 7.3 expects, not merely whether reviews happened: normalise the declared checkpoints into canonical gate order, name the mandatory gates never held, detect a gate held out of sequence, measure the schedule slip against the planned day, accumulate the action-item closure ratio over the held gates, and check th...

Determine whether the collected engineering activities declared for a microwave monolithic integrated circuit development actually cover the design effort, under ECSS-Q-ST-60-12 clause 7.2. Use when a project submits its MMIC design task set with owners, deliverables, effort and states and someone must authorise the work: refuse a duplicate task identifier, a free-text state or a non-positive declared effort, name the mandated design activities no task serves, separate a project extra from a ...

Optimize the arrangement of active cells and combining interconnect on a MMIC die by trading die area against thermal spreading against insertion loss, under ECSS-Q-ST-60-12C clause 7.2.10: score each candidate placement, reject the ones that break a channel-temperature ceiling, an area budget or a loss allowance, and keep the best weighted survivor. Use when several cell pitches or die outlines are on the table and one arrangement has to be chosen and defended. Refuses a pitch that walks a c...

Allocate the programme duties of a monolithic microwave circuit between customer and supplier under ECSS-Q-ST-60-12C clause 6: take the procurement mode, a foundry-led development or a catalogue part selection, read the party each applicable duty defaults to in that mode, then name the non-transferable duty handed to the wrong side, the applicable duty nobody owns, the duty both sides claim, the duty carried over from the other mode, and the agreed departure left without a deviation record. U...

Estimate the junction temperature of a die-form MMIC and trace the heat flow path through its mounting under ECSS-Q-ST-60-12C clause 7.2.5: walk the stack from the dissipating area downwards, let the heat spread at the declared cone angle, compute each layer's conduction resistance over the footprint it actually sees, sum them, raise the reference surface by the dissipated power, add the peak-to-mean non-uniformity of a multi-finger area, and grade the result against the derated limit. Use wh...

Analyze the parasitic inductance, capacitance and coupling a physical layout adds to a die-form MMIC under ECSS-Q-ST-60-12C clause 7.2.3: size bond-wire and on-die track inductance from geometry, form the coupling capacitance between adjacent conductors, convert both into reactances at the top of the operating band, locate each net's self-resonance, and grade series reactance, insertion phase error and conductor isolation against their budgets. Use when a layout or bond-plan has changed, a wi...

Assess the buying document and its companion batch acceptance document as one pair rather than two drafts. Use when ECSS-Q-ST-60-12C clause 9 content has to be settled for a microwave die: confirm each required item is present and actually stated rather than merely listed, hold each item in the document it belongs to, make the few items both carry say the same thing, check that the procurement specification really invokes the acceptance specification it names, and size the lot sample against ...

Validate the working method a buyer declares for acquiring microwave dies, step by step, against the methodology of ECSS-Q-ST-60-12C clause 10.1.2. Use when a procurement plan is reviewed before the first enquiry goes out: confirm every mandated step is declared, build the pass and fail branches into a graph, report a step no path can reach from the entry, hold a step that offers no route for the case where it fails, refuse a branch pointing at a step that was never declared, check each step ...

Assess the schematic item tabled at an ECSS-Q-ST-60-12C clause 7.3.3 die-form MMIC design review: confirm the drawn diagram is connectively complete, that every active device sits inside the foundry scalable-model window for unit gate width, finger count and total gate periphery, and that the bias arrangement as drawn puts each device at a quiescent point the derating policy and the process both allow. Use when a schematic package reaches a MMIC design review and its device sizing, bias feed ...

Review the sensitivity and stability item of an ECSS-Q-ST-60-12C clause 7.3.5 die-form MMIC design review: turn each declared variation source into a normalised sensitivity coefficient, combine the tolerance-weighted contributions root-sum-square against the allowed spread, then form Rollett's factor and the scattering determinant at every swept frequency and grade the sweep span itself. Use when a MMIC design offers evidence that it tolerates process, temperature and supply variation and wil...

Evaluate the simulation-results item of an ECSS-Q-ST-60-12C clause 7.3.4 die-form MMIC design review: build the corner matrix as the cross product of process, temperature and supply extremes, confirm every corner carries a run, take each specification parameter at its worst corner in the direction its target is written, and report the signed margin plus the corners nobody simulated. Use when predicted MMIC performance is tabled at a design review and the question is whether the corner coverag...

Review the summary design sheet review item of ECSS-Q-ST-60-12C clause 7.3.14 for a microwave die: confront the condensed one page overview with the characteristics the programme requires it to carry, reconcile every summarised value against the detail source it was copied from within the stated rounding tolerance, find the characteristics quoted with no unit, size the rendered sheet against its single page budget, and compare the sheet issue date against the latest detail issue, then close, ...

Evaluate the temperature, process and supply spread of an MMIC design. Use when a die must hold its specification over its thermal envelope, lot-to-lot fabrication variation and rail tolerance, per ECSS-Q-ST-60-12C clause 7.2.6: resolve the cold and hot excursions, the rail band and the process sigma the foundry data supports, turn each into a performance excursion through its sensitivity coefficient, add deterministic axes arithmetically and root-sum-square only genuinely independent distrib...

Evaluate the planned measurement coverage a design review is shown, requirement by requirement, and decide whether the matrix closes. Use when an ECSS-Q-ST-60-12C clause 7.3.8 test matrix review item has to reach a verdict: trace each requirement forwards to an activity whose method it permits, that carries measurable pass criteria, and whose conditions between them span every corner the requirement is specified over; trace each activity backwards so one closing nothing and one citing a requi...

Size the timestep, window and run budget of a die-form MMIC transient simulation under ECSS-Q-ST-60-12C clause 7.2.4: derive the spectral knee of the fastest switching edge, set the largest timestep that still resolves it, extend the window past the last declared event by a full settling time, convert both into a step count graded against the run budget, and check that turn-on and turn-off are both covered. Use when a switching, pulsed or bias-stepped circuit is being simulated, a run truncat...

Evaluate the electrical measurements taken on a wafer's process monitor structures against the foundry parameter limits, per ECSS-Q-ST-60-12C clause 10.2.4: validate the one-sided and two-sided limits, validate the site map, grade every reading inclusively, summarise each parameter across the wafer, and decide the wafer on both its median and its within-limit site fraction. Refuses a maximum-only parameter handed a lower bound, a duplicate site, a missing reading and a sample too small to be ...

Determine the deliverable set an accepted wafer batch owes and reconcile it against what the foundry actually handed over, per ECSS-Q-ST-60-12C clause 10.2.6: derive the required items from the batch conditions, validate the supplied list, and separate satisfied from missing, unusable and surplus. Treats a draft, an unsigned copy, a superseded issue and a right document at the wrong revision as four distinct unusable states, each with its own reason. Use when a wafer batch arrives and its pap...

Assess the process monitoring and wafer traceability a foundry holds while a microwave die lot is fabricated, per ECSS-Q-ST-60-12C clause 10.2.3: normalise the run record, confirm every mandatory monitored step carries a reading, place each reading in its control band, walk every wafer back through its lot to the mask set, and grade each excursion disposition. Refuses an inverted band, an unknown step, a wafer with two parents and a link cycle, and holds the lot rather than releasing it to ac...

Assess a wafer level screening and acceptance flow run before dicing, under ECSS-Q-ST-60-12C clause 10.2. Use when stress and measurement activities have been applied to a microwave wafer and the lot must be accepted or held: order the declared flow, hold an activity that needs separated dies, refuse a stress step with no parametric measurement bracketing it before and after, compute the relative drift of every monitored parameter at every probed site, group the sites as passing or failing ag...

Determine which screening and acceptance measurement sequence a procurement situation calls for under ECSS-Q-ST-60-12C clause 10.2.2, then grade a proposed flow against it. Use when wafers or die arrive already screened by the supplier, or from a process previously approved, and the question is which stages may be dropped and which order still has to hold. Selects one variant from the procurement facts, refuses a combination no variant covers, and separates a missing stage from an inverted ev...

Assess a wafer level screening campaign against the baseline provisions of ECSS-Q-ST-60-12C clause 10.2.1: lot coverage read in both directions, declared stress conditions against the agreed floor, and the record every screened wafer has to carry. Use when a die procurement must show that no wafer of the lot sat outside the campaign, that soak temperature and duration were declared rather than implied, and that the measured results are retained and traceable for the agreed period. Reports an ...

Use when a ceramic chip capacitor lot's test table has to become an accept or hold verdict. Evaluate whether a declared ceramic capacitor chip test matrix meets the ECSS-Q-ST-60-13C Table 8-1 programme: confirm every required test group is present and none is declared twice, resolve each row's sample size from a whole-lot, fixed or percent-of-lot rule without inflating a sample that lands on a whole device, take each row's failures against its accept number, and judge measured capacitance dri...

Use when a supplier alert, errata sheet, change notice or discontinuance notice arrives and the project must show which lots it touches. Assess a manufacturer alert or errata notice against the highest-assurance (class 1) commercial EEE parts a project holds, under ECSS-Q-ST-60-13C clause 4.5.3: match the named part numbers, resolve each holding date code into an ordinal and test it against the inclusive affected range, escalate a lot whose date code is unreadable instead of reading it as una...

Use when a device is offered as heritage rather than new development. Determine which assurance route a class 1 application-specific device follows under ECSS-Q-ST-60-13C clause 4.6.2: recognise a full-custom, standard-cell, gate-array or structured part and point it at the dedicated microelectronics assurance standard rather than the generic component flow, then weigh any heritage claim by comparing foundry, process node, package, design revision, temperature envelope and qualified total dos...

Use when a source inspection has to become a ship-or-hold decision. Evaluate whether a highest-assurance commercial parts lot may leave the manufacturer at the source buy-off of ECSS-Q-ST-60-13C clause 4.3.6: confirm an independent inspector whose qualification is still current, check the mandatory evidence pack item by item instead of scoring it as a percentage, refuse a buy-off dated before lot acceptance testing finished, group the nonconformances so an open major holds the lot and a waive...

Use when a drafted plan has to become a coverage verdict. Assess whether a component control plan covers the scope the highest assurance class demands for commercial EEE parts under ECSS-Q-ST-60-13C clause 4.1.2.2: refuse a plan carrying no reference or issue, take each required subject in turn, treat a subject named without a procedure behind it as absent, compute the covered share and the depth-weighted completeness, name every missing and every shallow subject rather than the first, check ...

Use when connector contacts and their sourcing must be judged before a Class 1 lot is accepted. Verify the connector contacts of a Class 1 commercial procurement against ECSS-Q-ST-60-13C clause 4.6.6: group the contact source as qualified contact manufacturer, integrated connector manufacturer, traced distributor or open market, read the minimum gold thickness the finish needs for the declared mating cycles off a durability table, grade the measured gold and nickel barrier against it, derate ...

Use when a declared component list, part approval package or equipment parts baseline is reviewed. Evaluate the declared component list raised for one equipment under clause 4.1.4 of ECSS-Q-ST-60-13C: confirm the list is scoped to that equipment and carries no orphan line, grade every line on the attributes an approval decision cannot be taken without, route each line to the authority its procurement category obliges, and keep apart an approval never requested, one still open, one refused, an...

Use when a Class 1 build has to show a commercial part runs inside its derated envelope. Verify that every electrical and thermal stress on a selected commercial EEE part sits inside the Class 1 derating limits of ECSS-Q-ST-60-13C clause 4.2.2.5: look up the part family's voltage, current and power ratios and its junction step-down, turn each maker rating into the largest applied value the rule leaves, grade the applied stresses and the predicted junction temperature against those limits, nam...

Evaluate a purchased commercial EEE lot through destructive physical analysis under ECSS-Q-ST-60-13C clause 4.3.9. Use when sizing a teardown sample per date-code group of a commercial shipment, sorting observed construction defects into major and minor categories from a named register, judging die-attach voiding and wire bond pull strength against declared limits, and turning the combined record into a lot disposition. Refuses an unregistered defect code, a largest void exceeding the total v...

Use when a parts record package has to be judged fit to retain. Audit whether the record package retained for a class 1 commercial part activity is complete and durable under ECSS-Q-ST-60-13C clause 4.7: refuse a record with no recognized type, identifier, issue, date or approving authority, name every mandatory report the package never produced, derive each retention end from the record date and its whole-year retention and compare it with the horizon the project has to reach, reconcile reco...

Use when an EQM parts list, build-standard delta or qualification transfer argument is reviewed. Evaluate whether commercial components fitted to an engineering qualification model represent the flight build under clause 4.1.6 of ECSS-Q-ST-60-13C: compare each fitted part with its flight-intended counterpart attribute by attribute, weight the deviations into a representativeness index, and map every deviation onto the qualification domains whose results stop transferring, so a package substit...

Use when an evaluation plan, heritage justification or evaluation report decides whether a part may enter a design. Evaluate whether the evaluation campaign behind a commercial part meets clause 4.2.3.1 of ECSS-Q-ST-60-13C at Class 1: grade the state of every campaign element the clause owes, from manufacturer assessment and construction analysis through radiation, endurance, environmental and electrical characterisation to assembly compatibility, test each heritage claim against manufacturer...
