A Novel IR Rework System
Lead-free raises the reworked board temperature – and increases risk of frying other parts. Dynamic temperature control and sensors help manage the heat.
Mixed Technology Gets Selective
Through-hole is still a fundamental processing step – most boards today mix SMT and PTH technology. Selective and fountain soldering can reduce skips and opens over traditional wave processes. Here's a primer.
