Hi Steve, I don't know if there are a lot of people who can decrypt the trace data. I think the manual mentions sending it to fuji for analysis. Maybe that would be something worth checking into. Regarding the Mecca check mode: I don't know if it wi

Should contact Rehm Thermal they have a whitepaper on pros and cons of Vapor Phase vs Convection.... Vapor phase traditionally targeted heavy PCB, large mass products better then lighter ones, due to ramp rate control being harder to attain vs say a

I need to clarify something for everyone. The end customer is the Military. Our customers are military suppliers who do in fact have quality systems in place. When we build the product we end up potting the unit so the customer never looks at the ele

We use a Wave Solder Plated Through Hole (PTH) assembly process to install a TO-220 Chip Package in the PCB board that we manufacture and have experienced lower yields on a number of boards with this component due to Bridges. The bridges on the TO-22

Hi all, We run an old Seho 1135C wave solder with a 63/37 pot at 250°C. It has been running well for a couple of years but we have noticed lately that all of the larger pads (terminal blocks, transformers, etc.) require additional solder to be appli

Thanks for the replies. The single missed lead is a bit odd - we usually have an entire area missed and that's due to the board not sitting properly in the pallet fingers. I figured in this case it was likely due to poor fluxing? We have always str

It's likely. Under any of the XX9100X standards, all procedures, including repair & maintenance, must be documented. The procedures define the proper steps and tools that are acceptable for people to do something. Procedures define the way your com

What type of flux are you using today? - Obviously you have already outlined the difference in the parent materials and parent material preparation, so using the same program/profile will not work; the characteristics are different. Try increasing p
