| | | Hello: | | | BACKGROUD: SMT components soldered on the top-side of boards that also require wave soldering have the potential to reflow during wave soldering. Reflowing these components during wave soldering is not good. It can cause cold jo

When evaluating AOI you must first define what type of inspections you want the system to perform, pre-solder or post-solder. What separates many mfgs. of these systems is how effective they are at finding post solder defects. This is where camera re

Although the following is not true capability machine assesment I feel that monioring the process at screen print, placement, reflow and wave gives results for both design and process guys to asses thire process. The project has been running since Ma
