Thank you for your response! I was actually the guy who emailed you a few days back regarding the blank.jpg error message in PCBsynergy. I would really like to try it, but that error is preventing me. I don't know how to initiate communication. If

We're having some problems with 0402's tombstoning. On a board with about 300 parts we're getting about 12 to 20 tombstones per board. The caps seem to do it more often than the res. The pads appear to be in accordance with IPC SM 782 amendment 1, S

I just came back from the UK, and the anti-American attitude is very similar to our new found anti-French attitude. My only question is what, if anything, do French owned companies have to do with its goverment's decision to not agree with our Presi

So if I get this right, your customer wants you to run this product as pb free even though it is not. In order to run this as pb free you need to run pb free paste. If you use 63/37 paste at the higher temps I believe that in addition to the compon

Ideally we want to mix the same lot numbers in a repackaged tube. Once again, these are partial tubes that have been thrown away. If the ratio is right to begin with the only change would be due to air exposure. Semco makes a TC seal which, if we

Kyle: I have also used the Kester, and the biggest difference I found between the two is that the MultiCore is a lot thicker. I had to make some printer adjustments to use the Kester; I had to use a little less squeege pressure to get a clean print

Hi Dreamsniper, the IPC land design standard is IMO a good reference. If you use the online calculator you can influence the result by varying for example manufactoring parameters. For the same lead width and same tolerances (and of course pitch) we
