Resources & Guides
A carefully curated library of technical guides, cheat sheets, and templates to help you streamline your test development and automation process.
ICT 3070 Passive Components
Episode 6 of the ICT Beginner's Guide covers passive component debug for resistors, capacitors, and inductors: → Why values read too high or too low and which BT-Basic option fixes each case → Frequency selection for capacitors and inductors (and why fr128 always needs ed) → AC vs DC test methods for capacitors, and when to use each → Phase Synchronous Detection for inductors → AutoDebug (ADB), PushButton Debug, and CPK for production-stable limits
ICT 3070 Fixture Design & Debug tips
Episode 5 of the ICT Beginner's Guide covers everything you need to know about test fixture design and debug: → Hardware components: probe plate, tooling pins, vacuum seal, safety shroud → Probe tip selection guide: single point, spear, serrated, star and when to use each → Wiring specifications: wire gauge, length limits, twisted pair rules → Bed-of-nails density limits and keepout zones → How to diagnose contact failures, phantom shorts, and VTEP faults → Error messages that point to fixture problems (not board problems)
ICT 3070 Digital & VCL
How does the i3070 test a digital IC without removing it from the board? Episode 4 of the ICT Beginner's Guide covers: → How digital tests work (vectors, drivers, receivers) → VCL — the language used to write digital tests → Overdriving, CRCs, and homing loops → SAFEGUARD — how the system protects upstream devices → Preconditioning — disabling and conditioning surrounding devices → Debug tips for the most common digital test failures
ICT 3070 MOA & Guarding
Episode 3 of the ICT Beginner's Guide covers: → MOA circuit and measurement equation → All 6 measurement buses (S, I, G, A, B, L) → The 3 measurement errors and their fixes → Shorts & Opens + Phantom Short debug → ASRU Speedup (DMC) on Revision N cards → Full options reference: wb, sa, sb, sl, en, ed, as
ICT 3070 Hardware Intro
This time we go deeper into the hardware itself because understanding what's inside the testhead makes every debug session faster. What's covered: → The 3 HP3070 system configurations → Module slots: ASRU, Control Card, Pin Cards → BRC addressing: how the system finds every node → Power subsystem: PDU, MPU, DUT supplies → 5 common hardware failures and how to fix them
ICT Beginners Guide
Quick-reference guide covering everything I wish I had when I started with 3070 systems: → The test execution sequence (and why order matters) → Essential BT-Basic commands → Opens & Shorts explained — including phantom shorts → Analog measurement examples with real code → Testjet, Polarity Check & Connect Check
