Anyone using these 2010 resistors? We just tried them and they bow like crazy during reflow. Not very good looking. Profile meets manufacturers spec. The part solders and works fine, but I'm a little concerned about putting anything on a board th

Can anyone help? We need a PCB material capable of working at 200 deg C, we are currently using Norplex P95 but we are being stung with huge minimum order quantites as we are in the uk and all the manufacturers have to buy it in on special order. Doe

I think Equipment wise things have changed little. Xray and Endo scopes have seen usefulness with in industry and if you want to add Laser soldering...Well that is some of the new Capital Equipment. Some areas that will grow over the course of some

Major advance: Productionization of SMT. Minor advances: * Realization and control of solder paste characteristics * Vision alignment controls in printers. * Evolution from mechanical centering [through laser alignment controls] to vision alignment

We like to use "enameled wire" that can be stripped by hot solder. Formvar [105�C] will not do that. Formvar was designed to with stand the hot oil seen in transformers. So, it requires either chemical or mechanical stripping. Most polyurethanes

Can anyone give a good manufacturer of hand held vacuum pick up tools? I have tried most of the common ones out there.(Vampire,Pen Vac,Selecta)They seem to work OK, but they still lose vacuum and drop parts after a couple seconds. We just got in a ne

Yes, Russ IPC-6012A w A#1 - Qualification & Performance For Rigid Printed Boards talks to solder mask requirements in 3.8. One interpretation of what it says: * Solder resist [solder mask] must meet the qualification / conformance requirements of S

Did not do the verification of replenishing reels at the last company I was with, and it bit us hard on a 300+ piece build, over 30 placements per board on 0603 size (if I remember right) were built right on 7 boards, then they ran out of reel 1, and
