IPC 620 Questions and Answers Latest
Version 100% Pass
What is the purpose of IPC-A-620 in the electronics industry?
✔✔ It provides requirements and acceptance criteria for cable and wire harness assemblies.
Why is proper insulation stripping important in cable assembly?
✔✔ It prevents conductor damage and ensures reliable electrical connections.
What should be avoided when soldering wires to terminals?
✔✔ Cold solder joints, excessive solder, and poor wetting.
Why is crimping preferred over soldering in many wire terminations?
✔✔ It provides a strong mechanical and electrical connection without heat damage.
What is the main concern when inspecting a crimped terminal?
✔✔ Proper wire insertion, correct crimp height, and no exposed strands.

, Why is proper wire bundling important in a cable assembly?
✔✔ It improves organization, reduces strain, and prevents electrical interference.
What is the purpose of heat shrink tubing in wire harness assemblies?
✔✔ It provides insulation, strain relief, and environmental protection.
How should wires be secured in a harness to prevent movement?
✔✔ Using cable ties, lacing, or adhesive-backed mounts without excessive tightness.
What is the purpose of continuity testing in a cable assembly?
✔✔ To verify that electrical connections are complete and functioning.
Why should nicks or cuts in wire strands be avoided?
✔✔ They weaken the wire and can lead to electrical failure.
What is the consequence of improper conductor positioning in a terminal?
✔✔ Poor electrical contact, increased resistance, and potential failure.
