| | We are using a mixed technology process with mostly through-hole parts plus some SMT IC's on the component side and some passive SMT parts on the solder side. We do not have a proper wave soldering machine for doing solder side SMT (double wave

That is a strange task. I must ask what is the purpose? When performing BGA Rework the goal is to recreate the manufacturing process of using the reflow oven. It is important to have even heat of the BGA and PCB from top to bottom. Using top heat o

| Has any body tried reflowing QFP's on both sides of a board. | GCollier Yes we do that quite often, we are using QFP132 with 0.5mm pitch in pure reflow process for both sides (no glue). It works well, the only problems we have seen was wiht compon

These parts are flat chip resistor arrays that have 4 end terminations on each side. It looks liek an IC but is typically in an 0805 and 1206 package type with convex terminations. .031" pitch from termination to termination and .011" spacing between

We are having a process related problem with pullup resistors on a controller card which has a I960 micro-processor. The controller monitors signal inputs and it's own resources then blinks a LED to indicate its working. The problem is that after a p

Reflow => Top side DIP => Bottom side glue => Bottom side SMT => Wave solder ... We couldn't keep the DIP clinch apparatus away from the bottom side SMT if we did the bottom side SMT prior to DIP.
