Resources & Links
A curated directory of the most useful places for aerospace circuit-card repair — standards bodies, free government documents, test-equipment makers, datasheets and learning. Every link was checked to resolve.
Standards are copyrighted — buy them from the official publisher (IPC, SAE, JEDEC…), never a pirated copy. These are external sites we don't control; for flight hardware, your facility's controlled procedures and IPC requirements always take precedence.
Standards & certification bodies
The organizations that publish the standards aerospace repair runs on, and the certifications employers recognize.
Publisher of IPC-A-610 (acceptability), J-STD-001 (soldering), IPC-7711/7721 (rework & repair) and IPC/WHMA-A-620 (harnesses). Buy standards and find IPC certification (CIS/CIT) training centers here.
Publishes AS9100 (aerospace quality management) and the ARINC avionics data-bus standards such as ARINC 429.
International Aerospace Quality Group — stewards of the AS9100 family of quality standards.
Semiconductor standards, including the moisture-sensitivity levels (J-STD-020 / MSL) you respect when reworking plastic-packaged parts.
Home of ANSI/ESD S20.20 — the ESD-control program standard behind your wrist strap, mat and audits — plus ESD training.
IEEE 1149.1 boundary scan (JTAG) — how ATE verifies connections on BGAs that no probe can reach.
Central storefront for purchasing many of the standards listed above.
Government & defense documents (free)
Authoritative material you can read at no cost — excellent for depth on reliability and mil-spec hardware.
Free NASA workmanship standards, including the NASA-STD-8739 soldering and workmanship series for space hardware.
NASA Electronic Parts and Packaging — deep, free material on part reliability, failure analysis and packaging. A goldmine.
Free PDFs of military standards and specifications — e.g. MIL-STD-1553 (data bus) and MIL-DTL-38999 (connectors).
The official U.S. government source for military specifications and standards.
Test equipment & measurement
The makers of the gear on your bench — most publish genuinely good free tutorials and application notes.
The ATE vendor behind many of the in-circuit and functional testers you will run.
Digital-multimeter maker with excellent application notes on measurement technique and electrical safety.
Oscilloscope primers and application notes — the "XYZs of Oscilloscopes" is a classic starting point.
Oscilloscope and DMM application notes and measurement tutorials.
Oscilloscope and signal-integrity learning material.
Affordable bench scopes and DMMs with usable manuals — handy if you build a home practice bench.
Components, datasheets & calculators
Decode an unknown marking, pull a datasheet, or check a value.
Datasheets for nearly any part, plus free reference tools including resistor color-code and unit-conversion calculators.
Another deep datasheet and parametric-search source.
Cross-reference and datasheet search across distributors — great for decoding an unfamiliar part marking.
Application notes and reference designs for analog, power and logic parts.
Op-amp, data-converter and precision-analog design references and tutorials.
Learning & tutorials (free)
Fundamentals, refreshers, and technique — all free.
A full free electronics textbook plus articles — strong on fundamentals.
Clear topic-by-topic explanations of components and circuits.
Approachable tutorials on multimeters, soldering and components.
Practical guides on soldering, tools and electronics basics.
Dave Jones's long-running channel and forum — superb DMM and oscilloscope tutorials.
Board-level repair community
Consumer-electronics focused, but the hands-on diagnostic and microsoldering technique transfers directly. For flight hardware, always defer to your facility and IPC procedures.
