You say you are new to SMT. If no one at your facility has SMT experience you will want to get equipment that comes with good support and excellent training. This can be difficult with used equipment. Make sure the equipment you end up selecting h

I have a production defects on smt mounted spring that the designre at my compnay is try.the spring act as conduction between the resistor capacitor network and mount with the prefrom and then reflow thru the oven. the design intent for spring is mec

This "character" is one of the many trolls that lurk here at SMTNet - Shocker, wavemaster Larry, and the Guru (Moonman in disguise) are among the other few. I felt compelled to go to Moon's site again to look up this "problem" and just want to let e

All you funny guys and your names. Listen, this is whats wrong with this forum and the world today. Too many clowns making fun of serious buisness. What the hell is POD group anyway. Sounds like some outer space movie to me. Maybe they hung up o

Thats a great idea Doc. If we all listened to your suggestions, there would be zero defects in PCB manufacturing. I bet your using Bahodum solder which, I'm sure, is incapable of defects. Pavel, sounds like you can rule out reflow as the problem.

I mean if you are using the same stencil for the top and bottom of a board. Thanks to everyone for the help. From what I gather, it will work when the stencil cut-outs are offset from center in the Y-axis. Doesn't work too good in the x-axis, beca

Yes, I realize the odds of anyone having any experience with these things is limited but I have to start somewhere. Can anyone with knowledge of model TRM-SMD give me a holler? I have some questions about how they were set up at the factory, specifi

RoHS actually allows for up to 0.1% lead in solder. Unless you are really sloppy at cleaning your tools it would be very unlikely that you would get 0.1% lead into your lead-free process (remember leaded solder is only about 50% lead). Regards, Ber

We are using Alpha UP78, which has generally good SIR values. We are seeing current jump from around 6 micro amps to 60 micro amps in a very small percentage. This does not seem to be likely with just ions immediately after reflow. The current would

Hi, Hope your machine is back up and running. Are you sure it is not program or PD (part library) related? Try power off and back on and delete the machine program from the machine. Then- Power off and back on and see if the VP error is gone. It
