I was wondering if anyone could direct me towards documentation on shear test methods/apparatus to test the bond integrity of a solder ball to its substrate. Thanks.

There has been an increase in the number of defects regarding the solderability of resistor network arrays(pin opens specifically). Has anyone else experienced this? Also, does anyone have any FYI that they would like to share?

Hello Russ, I'm not quite sure I understand your question. Are you saying that you must hand solder these connectors because the gold plating doesn't allow other though hole processing methods to wet the solder the length of the pin in the PTH? Reg

Jim, you are right in this. these connectors have long pins 1/2" or so that protrude through the board and are used for mating into a female connector on some other assembly. due to both length and "no solder allowed in contact area" criterias thes

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)?

Hello, everyone. We are checking a Panasonic Soft Beam machine. Did any one has expenience on Panasonic's softbeam machine - soldering performance, solder speed, easy to access? Anything would helpful. Appreciate your help.

Stephen, Magic!! Soldering in the N2 environment did just as you said. Easy to clean the post solder residues. Many Thanks!

I was reading an article on reflow soldering of through-hole components today under the "knowledge base" section. I would like to hear from any of the SMTA members if their company is presently using this approach and their success. I would apprecia

Ianchan: Watch yourself. Old style vapor phase oven are being replaced by ovens build to capitalize on new generation fluids [ie, Ausimont, F2, etc]. These machines could fill roles in soldering of no-leads.
