I have an application that requires soldering pieces of metal (copper plate and copper fins to make a heatsink). Each piece is about 1 lb. I cannot test it in our reflow oven (5 zone) since the piece is about 3" in height. Has anyone attempted to

I do not have a ERSA Versaflow but do have some ERSA equipment. Only can tell you I will most likely not purchase anything else from them. The experience I have with their service after the sale would have to be rated VERY low. In addition, they emai

We are using one BGA that has 7 mil bumps on a 20 mil pitch. We use the manufacturer's recommended pad and aperature layout, which is an 11.8 mil square overprint on a 6 mil land. At 11.8 square, you need to use a 4 mil laser cut or a 5 mil e-form st

If the white residue is from a no-clean flux or no- clean solder flux core you can leave it on the board. (Consult with the flux or cored solder manufacturer) Because after being encapsulated with conformal coating the residue is sealed from humidity

Soon we will be manufacturing board assemblies on our SMT lines that will utilize both lead and lead free water soluable solder pastes. I have read some discussion about change-over from lead to lead-free jobs related to machine cleanliness, etc. H

The most important thing you can do is to maintain the same electrical potential between the ESD-S product, the operator and the worksurface. This is typically achieved through a grounded dissipative worksurface and an operator grounded via a wrist s

We have recently undergone perhaps the largest series of upgrades possible on these machines. This was a technology and cost based decision. Altough we had some issues, the main point I would make is not everything is/can be tested. There should alwa
