I didn't attempt to get any written guarantee, but took a leap of faith based on our various communications. The broker was also a refurb operation so I figured we could resolve any technical problems without too much trouble. At this time I'm also

Hi, I have a CSM84, PA1306/20. When I got it, a lot of the offsets had been zeroed out. I figured out a procedure to calibrate the back feeder rail, but haven't come up with a scheme to calibrate the mechanical alignment unit. I have it close, but

Hi All, I'm setting up the F4G software for our line (currently using MCS30). I made an adapter to connect the CP4 line (that was connected to the MCS30) to the PC. Then I tried to transmit a program but I keep getting this error: 41A27F9D: Error o

Since I'm new to the forum I probably ask previously answered questions (that I have not found) but I would be grateful if someone could clarify this for me. I'm in R&D at a company where we design low volume (1k-10k) fairly complex PCBAs for our pr

Hi, I'm working at a very small electronics assembly firm and we need to get a better thermal profile of our reflow and solder wave ovens. Our firm is part of a larger firm that was set up to help handicapped people find work in the Netherlands. Yo

ceramic cap crack

Electronics Forum | Fri Jul 09 19:09:52 EDT 2010 | rway

A couple of things: Does the cap break if you try to remove it with hot air? If not, than you are breaking the caps do to mechanical stress. We have had similar issues. I don't think your board is suffering from mechanical stress from depaneling o

100nF 0805 ceramic cap with 25 Ohm resistance? Why?

Electronics Forum | Tue Jun 29 14:55:22 EDT 2010 | rgduval

For the capacitors that Yageo analyzed... Were they taken out at representative points in the process?? ie. were samples taken from pre-assembly, pre-ICT, post-conformal coat, post-final test? You note that the parts 'seem' to be ok up to ICT. And
