The board thickness is 50 thousandths. The style of the BGA is a 324 ball BGA that has an isolated center region. The machine that I am using is the Air-Vac DRS25. I'm not too sure why the pads are being removed when I am desoldering. I know when

So I got to work today. They asked me to finish removing all the parts for the CBS (center board support). While doing this I removed A Tor Tender tolomatic 1/2 inch gear box from the shaft that widens the rails. It is used to link the front and rear

Veering back over to table-top stuff, any comments on the APS Novastar models? Specifically, the LE and LS40 with and without vision? I'm assuming I'll probably need vision, but maybe since the finest pitch parts on my board (SOT-363) are 0.65mm pitc

1. Pad design. Most of the tombstones are result of wrong pad(land) design. One pad is significantly bigger than the other or the metal laying under one side of the part is much more than under the other side. 2. Part placement - should be in the ce

We have run Mydata machines for 10+ years with no ESD damage from the machine itself that we know of. Can you tell us how you have verified it is the machine causing the ESD damage? It seems to me the ESD damage would be far more likely coming from
