Review of Hot Air Component Rework
Review of Hot Air Component Rework
When surface-mount components started to take over, edging out through-hole components, a number of hot air-based rework systems appeared on the scene. Many were large, some small, but all had various means of delivering hot air to the component with varying degrees of process control. Despite their diversity, they all had one thing in common -- they were fine for removing components from a circuit board, but none were particularly ...

Restoring Gold Edge Connectors
Review of Hot Air Component Rework
From time to time, gold edge contacts become contaminated with solder. This most often occurs during reflow of an assembly and may be caused by solder spatter or solder paste contamination of the contacts due to improper handling, or other reasons. Solder contamination is certainly an unacceptable condition because oxidation will ultimately ...
