Broken capacitors

Electronics Forum | Fri Dec 01 07:28:37 EST 2000 | JM Lasserre

I just started an analysis concerning broken capacitors (0603 ceramic). My first question concern the standard used to determine the maximum force a capacitor 0603 can support on a pcb. Some capacitors suppliers use the die sheer test of MIL-STD-883

Our SMTproduction has next troubles : 1. irregular 0603-components in tapes (different solder shapes) makes vision errors on placement devices 2. big solder amounts makes pickup and placing errors 3. some tapes delivery delays , so production halts f

Troubles, troubles, troubles. If it weren�t for bad luck, I wouldn't no luck at all, eh? Tough business. Comments on your trouble are: * On machine vision errors from less than ideal capacitors: This is life. Reprogram your machine to either wid

Cracked chip capacitors

jagman, take a hard look at a capacitor under the high mag microscope before you start assembling it.. I remembering seeing cracks even before the assembly. apparently all chip capacitors have crack at the intersection between the capacitor head and

Ceramic capacitors cracking

Brad, This is a common problem and may relate to the design of the board. In all cases when a device such as a capacitor is place near the edge of the board and the board must be de-panelled, the capacitor must be parallel to the break line. If the

Does anyone have any insight as to the cause of cracked chip capacitors during SMT? Z-stop? Thermal shock? Any help is appreciated.

Wow. And I thought I was the only one having problem with ceramic capacitors.I too am having problem with cracking ceramic capacitors 1206 package.We changed vendors and still having the same problem. I had to reverify my entire process and I had to

If you are facing problem of craked capacitor only after breaking of the panel into individual PCB's, this may be due to stress being generated on the capacitors terminals. The stress may be due excess pressure being applied on the panel for breaking

Here is some talk about MLC capacitor flex cracking...what happens with depanelizing: http://www.kemet.com/KEMET/web/homepage/kechome.nsf/vapubfiles/f2106/$file/f2106.pdf Here are some other files on breaking capacitors: http://www.avxcorp.com/doc

Reflow of 0402 capacitors

Electronics Forum | Thu Mar 08 12:40:54 EST 2001 | Ralph Merk

We are currently using 0402 resistors and capacitors in our production process. Our equipment is as follows: - DEK 265 - Siemens S25/F5 - Vitronics XPM520(5 zones) - 2% silver solder Alpha WS678 The problem is that randomly some 0402 capacitors are
