I have seen this before, our problem was palladium termination of this component. We could not change suppliers so we use a "reverse homeplate" stencil design to put the majority of paste directly underneath the solder terminations of the component

Sal: You are Correct running firts the reflow side then glue side. In my Experience I've seen a reverse procesess( first glue"cure" and then reflow side) but the quality results were not good, because We realized the Glue tent to cristalise and when

This technique is commonly known as "black boxing". The majority of IC's are marked with ink. Simply use a tiny piece of sandpaper to "scratch the surface" and render the device blank. This will work with Laser marked parts as well. If your volum

If you want to tinker a bit with old machines, you could buy an inexpensive ( under $ 10,000 ) used Pick&Place machine and reverse the polarity on the tape feeding motor. If you don't heat seal the cover tape, but use pressure sensitive cover tape,

No argument here. But I've don't think I've ever seen solder balls on 0402s. Even when they're placed on narrow G dimension pads, where there is little toe fillet, I've never seen a solder ball. But your idea of reversed homeplates would work grea

We have problems of solder shorts while using DEK Infinity printers. Some of the manufacturing lines are configured ina way that the side (bottomside) of PCBs mostly with passive parts is screened first and then the otherside (topside) of the PCBs w

Anyone who thinks that China is behind in the technology curve...hasn't been there recently. They learn fast, they can replicate (reverse engineer) like no other. It won't be years before they are at the same level as US OEM or EMS...it will be a lo

Hello. I am an HR Manager looking to benchmark pay rates for engineers in the Midwest with experience in reverse engineering and component level repair experience. The experience should be in BGA type repair with the core experience in setting thermo

Hey Brian how are you doing? We also have one of these feeders and it works great! The best feature is the being able to reverse the feed wheel to backfeed parts. Just talked to the guys at Hover-Davis yesterday and they have had feeders in service
