Yea, that seems pretty obvious to me as well but we have a customer that's not buying into running lead-free in conjunction with lead. They strongly believe that we need to install a dedicated lead-free SMT line inclusive of in-line wash system. Th

Thanks to those that responded. I eliminated the light curtain problem. The metal plate the light curtain pcb bolts to was bent. I had it aligned in our machine shop and it worked properly. I forgot to mention the error was pooping up with no fee

The quick frame does work well with the DEK 265, but we feel that tensioning is user dependent and introduces variation into the process on an operator to operator basis. Also, because tensioning occurs only on two sides (instead of four) this also i

We recently have received a lot of warped (bowed and/or twisted behond IPC 600 specs.) bare boards (some our fabricator's fault, some ours by design) and I can't help but figure that long term reliability will suffer when building product with them.

DON'T do it!!! The two problems you'll have are: 1 Poor manufacturing process control, resulting in weak solder connections. 2 Weak solder connections are stressed, when the board is straightened upon installation in the "box". There's several hits

Do you bond with Al or gold wire? What happens if the Ni is over 150 microinches? Thickness of nickel is one those things that we have not been consistent with. The industry seems to pretty much universally call for 100-200 microinches. Our old board

I have a Zevatech 720 that was working great until one day a "E9001 the emergency stop button has been pressed..." error popped up when I turned the machine on. We traced out the circuit and found out what board it went to. I found a replacement an

Hello, I have just installed the demo version of GC-Powerplace. Could anyone here walk me through the process to generate pick and place file from gerbers? I don't have solderpaste layer. All I have got is signal layers (top/bottom), soldermask, sil

Jim, Thank you for the input. Could you please check your standard filter pore size? A model number would be valuable. How many shop volumes (in cubic meters) do you pump per hour? Customer is seriously thinking over installing AC system similar to
