I am looking into purchasing handling and transferring carts/magazines for PCBs... Can anyone recommend places for me to find these? Websites perhaps?

Another thing we see is solder balls (sometimes fines, sometimes larger stuff) in the vias after a misprint has been poorly cleaned, as in wiped down but not washed. They end up in the plated through holes too, but those get nicely cleaned up in the

I meant to include this in the original message. One, the solder balls are on the circuit side of PCB. Two, some of the vias on both top and bottom are closed and some are not. Is this a process problem with the board house(s)?

Closed by solder mask? At any rate, still sounds like wave solder. Take a look before and after wave. That should tell ya.

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?

Hi All - My question is how do solder balls form and stay in the vias? The assembly goes thru SMT top placement, reflow then thru hole components mounts on top side as well. The board is sent thru the wave solder process. Has anyone experienced this

If you have solder balls in vias on the "component side" it probably is your wave solder process. Most waves have an option that is designed to make sure your surface mount parts solder - but if turned up too high, can actually push solder up throug
