Lead-Free Wave Soldering

Name: Lead-Free Wave Soldering
Delivery Method: LAN or Web                  
Students

These lead-free rework modules are intended for process technicians, supervisors and process engineers responsible for the lead-free wave assembly.

Objectives

Participants successfully completing the course are able to identify and explain:
• Impact of lead-free materials on the wave soldering process
• Commonly used alloys, differences in lead-free alloys and tin/lead
• Reliability concerns, assembly acceptance criteria, cosmetics
• Flux specifications, VOC vs. water-based, clean vs. no-clean fluxes
• Elements of machine set-up for lead-free wave soldering
• Fluxer requirements, pre-heat configuration for water-based fluxes
• Benefits and indicators for the use of Nitrogen
• Lead-free impact on the solder pot, changing over to lead-free
• Setting up the process, measuring flux application
• Pre-heat, contact time, alloy temperature range
• Dual-wave, board-warp, prior processing, cooling considerations
• Selective soldering technologies to solve special assembly problems
• On-going monitoring, controlling solder-pot copper levels
• Build-up and handling of dross, solder pot lead contamination
• Common defects and indicators, and process adjustments required
 

Qualification and Certification Testing

This training interactive learning module constantly checks whether or not the student is learning. At the end of the module the successful student is awarded a certificate. A criterion-referenced test with feedback and a response to each question is given.
