You are correct that hand soldering ceramic capacitors often causes them to crack. They do not take thermal shock well. You might be able to reduce the amount of cracking by following the rework repair guidelines discussed in the fine SMTnet Archiv

I have changed job and now i have some problems. Previous experience was with high volume production and not so high quality level (class 1, 2 according IPC). Now i need to produce very high quality (and very expensive) PCBAs in Low volume production

Ladies and Gents: There have been several studies including (http://www.solder.net/PDFs/LeadFree_BGATesting_InitialCycling_BEST.pdf) which have shown lower fast pass yields with solder paste. Based on internal projects of 1000+ of the same BGAs we a

Dear Colleagues, I am working with a new prototype product that is presenting some interesting problems. My Engineering Dept. has made some suggestions that I find a little odd. I am looking for some confirmation from fellow SMD personnel as to the

In general terms, guidelines for moisture sensitive devices (MSDs) say that you shouldn't put a component through reflow after it has reached its exposure limit with respect to moisture absorption. When using an automated hot air rework tool to remo

| Mornin! | | We just had vendor in here pitching a "low-temperature rework system" which was intriguing, but too expensive. He did get me to thinking though, beyond heating ceramic caps before hand-soldering them, it seems like it would be ad

1 CAN WAVE SOLDER AFFECT OR DAMAGE BGA? Sure. Since you are vague, assuming: * Partially assembled board was not stored to prevent moisture absorption. * BGA is in a plastic package. * Partially assembled board was stored long enough to exceed th
