About the programme
Course Overview
IPC-A-610 and J-STD-001 define what an acceptable solder joint, component placement and mechanical assembly look like for electronic products, but applying them correctly means knowing which acceptability class applies to a given product and recognising the same defect under a microscope, on an automated optical inspection image or on an X-ray of a hidden joint. This course walks participants through the three acceptability classes and how end use determines which one applies, then into specific criteria for through-hole and surface-mount solder joints, component orientation and mechanical assembly including connectors and cable harnesses under IPC-A-620. Sessions cover setting up and interpreting automated optical inspection and X-ray inspection for hidden joints such as ball grid arrays, and applying IPC-7711/7721 rework and repair procedures without introducing new defects. The final modules address electrostatic discharge control during handling, conformal coating inspection, and building a first article inspection process that catches process drift before a full run is affected. Participants leave with an inspection criteria reference and a defect classification guide for their own product mix.

01IPC acceptability classes and solder joint criteria
2 sessions · 8 points
Session 1Understanding acceptability classes and end-use requirements
- Distinguish Class 1, Class 2 and Class 3 requirements and the products each one applies to.
- Select the acceptability class appropriate to a product's reliability and end-use environment.
- Apply target, acceptable and defect condition definitions consistently during inspection.
- Resolve conflicts between customer-specified criteria and default IPC class requirements.
Session 2Inspecting through-hole and surface-mount solder joints
- Assess through-hole solder joints for fillet height, wetting and hole fill against J-STD-001.
- Assess surface-mount solder joints for wetting, voiding and component alignment criteria.
- Identify common solder defects including insufficient wetting, bridging and tombstoning.
- Distinguish a cosmetic solder imperfection from a criterion that requires rejection.
02Component placement and mechanical assembly
2 sessions · 8 points

- Apply criteria for fine-pitch and bottom-terminated component placement quality.
- Document placement defects with location and defect code for trend analysis.
Session 2Mechanical assembly and IPC-A-620 harness criteria
- Inspect connector mating, strain relief and fastener torque against assembly requirements.
- Apply IPC-A-620 criteria to wire and cable harness terminations and crimp connections.
- Verify wire routing, bundling and clearance meet mechanical and safety requirements.
