As I am soldering SMT electrolytic capacitors - I guess, soldering robot.

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

Any one have any experience on solder fillet problem on 0603 chip capacitor ? The phenomenon is solder wetting on one terminal is very good and totally no solder wetting on the other terminal. The positing of capacitor is right at the centre of the

| Can someone please advise me to the rework procedure for removal and replacing Ceramic Chip Capacitors (e.g. 0805, 1206, etc.)? | | Is it necessary to pre-heat ceramic capacitors before soldering them onto a PCB with a soldering iron? Is this just

14,000 uf now that's a BAC!!! Your thinking is correct. Connecting capacitors together works just opposite to connecting resistors together. * Capacitors in parallel add like resistors in series [Ct = C1 + C2 + ... Cn]. * Capacitors in series add l

tombstone. These we do get nuts about with the fabricator.] 90+% of our capacitors are commodities. [So, we could care less who supplies them.] We qualify the remainder based on engineering requirements. Capacitors are a widely diverse class of

I have seens cracks from AVX capacitors too. The thing is they already have micro cracks that are not visible to naked eye. When the capacitor is stressed the crack expands. One way of mitigating this is by tweeking your process. See how your singula

Capacitor working voltage One very important rating of capacitors is "working voltage". This is the maximum voltage at which the capacitor operates without leaking excessively or arcing through. This working voltage is expressed in terms of DC but th

Well, most of the capacitor are thru hole, then pcb's goes to adhesive process upsidedown to continue SMT process in which , maximun tempetarure is 120�, so temperature is not problem. About SMT capacitorS, I will check temperature specs before mount

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
