Mantis: Kenny reflows paste on [wave solders] all via, not just the test via, to plug the via and provide for a pressure seal between the board and the test fixture. Beyond that, since solder is softer than copper [and fills the hole better], solde

It is possible to use a selective wave soldering fixture to "mask" the BGA devices from the wave. Unless you have a very thick board or one that is tough to heat, you should have no problem with BGA. Of course you should run some process experime

I just reread your message. The wave soldering is on the other side? I.E. The Through hole parts are on the same side as the BGA. This would be the only way to do it. But reading the message again it could be interepted as the through hole parts

Actually cleaning of PCB's may see a resurgence with the lead free movement. Higher temps and more aggresive fluxes might need to be clean depending on your board and process. In addition Wave soldering solder pots (in some cases machines) may have t

We are in need of a replacement conveyor belt for an unload-end conveyor(post wave solder). The part number we had at one point (formerly PCT automation) was 65-4008-4 (Belt, Flat-W=23.75 L=171.70) green high temp conveyor belt. Any help would be g

Not as such. Choices are: 1 Cut and epoxy some board foil from your board fabricator. 2 Sacrifice part a pad repair kits from the likes of: * Engineering Lab 905-785-1982 * Circuit Technology Center 978-374-5000 * General assembly suppliers catalog

If you find your self interested in an electrovert machine we have a UP600 for sale, a good machine if you have experience with electrovert. As for a buying guide I'm not sure if there is a reliable source who has compared the different models.
