Hello, Have anyone of you any experience of mounting BGA-s on both side of the PCB in lead free process? Have you seen any problems after the second reflow? Is it something special to focus on? /Thomas

We have not had very much luck hand dispensing on small pads. It can be done but you will most likely have bridging and insufficients.

I have noticed certain BGAs void more than others. We place about 8 different brands of BGAs and only one brand voids like crazy and we have to adjust for it.

CW, make sure your customer is aware of the affect high temp might have on adjacent components on the board. I guess you must have already checked out the rated temperature of all the components on the board

We are having significant issues with lead free parts on leaded assemblies. Particularly grainy and non-wetted solder joints. Does anyone have any solutions.

Does anyone know of a place that repairs Cognex proccessor cards. I have several of the 5200 boards from MPM's that need repaired. Anyone have one for sale?

I have a schematic drawing on a board I've never seen before. It looks like a zener but has 2 arrows pointing toward the junction line. Anyone have any idea what type part this is. The part itself looks like a radial cap.

I've got some MELF packages that reflow and connect but later fall out of the solder pretty easily. We are not using epoxy but, the parts have fillets per IPC standards. We have not looked at cross-sectioning for IMC and don't plan to at the moment
