Thanks for your responses, gentlemen. I'm really just looking at options, and frankly, being a novice at this stuff I'm looking for the info. required to make a semi educated decision. You, kind sirs, are my educators. And that probably scares m

Sal: Hey that customer standing around staring at you sound like fun, yeh right!!! Wolfgang makes good sense, but, in addition, I�d like to drill-down on board fabrication (har har har) a little bit (har har har) more. You say the holes are the cor

Cyberoptics makes a device called a Cybersentry. wonderful machine. Will work in line or off line. I used one in a former company. You program what pads and locations you want, and it can measure volume or height, and give you charts. You can en

Cory, I've got a lot of experience of testing of this type. The physical (not chemical) nature of the flux residues is the crucial issue in compatibility. If you have a softer residue (either caused by a thick initial solder paste deposit, or a low p

This is not a real demanding job. We've talked about materials sources before, check the fine SMTnet Archives. Responding to your question, try: Circuit Repair Rowley,MA 508-948-7973 [Jeff Ferry is a contributor to SMTnet, so ya gotta go there fir

It is only after the reflow heating process that the peaks may show up, as the solder build up in some vias(due to HASL'ing) might drip down during reflow. I don't think I've ever heard of it being desirable to have a bare copper surface that will ox

I�m not sure but it looks like the �mini-chip thingie� is a filter cap if so it should not stop the playstation from working, may not work like you like but should do something. Did you use any static protection? If not you may have fried one or all

John, We regularly wave solder electroless silver finished boards (Alpha Level)with mixed SMD and through hole parts and do not have any problems. We have changed a number on PCB's from HASL to electroless silver, mainly for the benefits at SMD whe

Ok fellas, tell me how you'd fix this! I'm having melf connectors that are tombstoning in the wave, NOT the reflow, the wave. I've never seen this before. All other parameters are the same...solder, preheats, placements, the board, building humidi
