INTRODUCTION FOR IPC WHMA 620E: MECHANICAL ASSEMBLY AND CABLE HARNESS TRAINING

This comprehensive 2-day IPC/WHMA-A-620 training (“Requirements and Acceptance for Cable and Wire Harness Assemblies”) is designed for operators, technicians, and quality inspectors involved in the cable and wire harness manufacturing industry. The program provides a thorough understanding of internationally recognized IPC standards for cable assembly, including best practices for crimping, soldering, and inspection processes. This course is also suitable for organizations seeking HRDC claimable training in Malaysia, allowing companies to upskill their workforce while optimizing their training investment.

Participants will gain in-depth knowledge of workmanship standards, quality requirements, and acceptance criteria for cable and wire harness assemblies. The training focuses on improving inspection skills, identifying defects and non-conformance, and ensuring compliance with IPC/WHMA-A-620 requirements to enhance product quality and reliability in production. Emphasis is also placed on understanding common industry issues and how to prevent defects at the source.

This hands-on and practical training also covers proper handling techniques, quality control procedures, and methods to reduce rework and manufacturing errors. Participants will be exposed to real-world scenarios and examples to strengthen their understanding of cable assembly processes and inspection standards.

By the end of the course, participants will be equipped with the skills to apply IPC cable assembly standards effectively, ensuring consistent quality, improved productivity, and compliance with industry best practices. This will ultimately support organizations in achieving higher efficiency, better product reliability, and stronger compliance with international manufacturing standards.

COURSE OBJECTIVES

participants shall enhance knowledge and skills in the following fields:

• Understand IPC-A-620 Class 1, 2, and 3 requirements (focus on Class 2).
• Identify acceptable vs. rejectable conditions in wire preparation, crimping, and soldering.
• Proper handling, securing, and testing of cable assemblies
• Understand wire harness components, tools, and materials.
• Master wire preparation, cutting, stripping, and crimping.
• Learn soldering techniques and connector insertion.
• Perform mechanical assembly, cable routing, and bundling.
