INTRODUCTION FOR IPC 7711 – ELECTRONIC ASSEMBLIES SOLDER REWORK SKILLS TRAINING
This IPC 7711 solder rework skills training will provide the participants with the knowledge and skills required to maintain consistent quality output with constant monitoring of soldering issues and rework skills. Able to understand solder quality and its accept/reject criteria standards based on IPC 610.
COURSE OBJECTIVES
To enhance knowledge and skills in the Removal and Installation of Components covering the following areas:
- To minimize quality issues related to soldering and solder reworks.
- Provide inspections and rework support in the manufacturing process.
- Reduce inconsistency in soldering and rework skills.
- To improve and upgrade the skills of current Manufacturing solderers and rework specialists.
- To reduce component and PCBA scraps which can be very cost-effective with great savings
- Change mindset and stigma of soldering and rework specialist capabilities and quality of training received
- Improves confidence and competence level of specialized rework skill workforce in the plant.
