cap size and copper thickness vs part size questions

Electronics Forum | Mon Nov 07 16:31:47 EST 2005 | CW

hi Bob, Thanks for the info. I understand your comments, but I am looking for specific guidance, If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? (I realize this is dependent on h

Mydata centering jaws causing ESD and part damage

Electronics Forum | Mon Nov 10 09:11:51 EST 2014 | rgduval

The centering jaws are made out of copper, I believe...and conductive. I'd suggest that the conductivity of the copper makes it a fairly poor source of ESD damage in a component. I have observed physical damage to components from the centering jaws

Hi CW, Regarding orientation, yes, your diagram is right - see the following link for confirmation. http://search.murata.co.jp/Ceramy/image/img/A18X/C2EB3C.PDF Regarding information on bending strength you want to talk to your local Murata office

Solder paste on the pads will keep part aligned. If you do not use paste, you will need to apply tacky flux. You should not run without one or the other.

AXI and AOI

When you look at the capabilities of Combo machines they tend to sacrifice performance when compared to separate X-ray and AOI machines, meaning they don't do either the X-ray or AOI operations as well as a machine that was designed to do only one. A

Siemens Siplace 80S15 causing Line Controller to hang up, and 80S15 keeps waiting for machine data from Line controller

Hello Sarason, Unfortunately the machine is no longer supported and we are such a small company we can not afford to replace this machine. Thank you for your advise, I will check for additional parts stuck in the machine (long shot but worth the time

Katrina, it is one of both: 1. Communication error - try to initialize machine with line controller OFF. This should tell you if machine can initialize on its own and if the problem is on the machine. Try without the feeder carts, look at the cards

Hi, SMTASSY that�s what we do, soldering our double-sided-finepitch-BGA-and all-the-other-stuff-boards in vapourphase because it�s the only thing we have. First, we do not do real series produktion, only prototyping up to som
