| Hi Stoney, | Justin is giving you some good advice, unfortunately these kinda' problems sometimes call for the ol' D.O.E...otherwise, you could be chasing your tail for a while until you figure out exactly what's causing your problems. | Has

dedicated fixture works best if the board is very much populated. But if the parts to be inserted are less than 300components, adjustable fixtures may be used. But the secret of good insertion is a precisely measured tooling pin to prevent the boards

Some times the PCB manufacture sends PCB panels with bad circuits, there are three ways to make these PCB without placing parts on the bad circuit, Well two in fact plus my method. (1) Placing a light mark on a dark background (or reverse) then the

Hi Al, Thanks for the suggestion. Yes, I should have said that the cable has been checked and another cable tested with the same results. In addition to the three wires that carry the transmit data, the receive data and the data signal ground, the

Oh yeah, I've seen this before! Generally, if the hole sizes are correct (including plating), and the PEMs are within spec, we've found that this is most commonly caused by insufficient support of the PCB during insertion. If you can eliminate supp

We use these machines to insert swedge pins. When I first started here, there were certian programs that we ran that required us to put in a machine offset of +.120 in the X which is a lot. after learning the machines better, I realized that whoever

Do you have BEC (Board Error Correction) > on that machine, and if so, did they > give you the alignment plate for it? I don't know if we have BEC on the machine. I can't even search the 550 page manual that was finally sent to us in a pdf file

I agree with jdengler on the rotary table being skewed. You need a couple of dowel pins (1 1/2" long x 1/4" dia., I think) to align that disk. Each idler is held on an eccentric cam and can be adjusted to square up the rotary table by dropping the do

We've had some experience with Universal's machines as well. Aside from the mechanical problems you're experiencing, that level of control hardware is susceptible to power spikes/fluctuations. Save yourself some trouble later on and get a good UPS.
