cap size and copper thickness vs part size questions

Ceramic capacitors larger then EIA size 1812 are known to be very susceptible to thermal shock damage due to their large ceramic mass.

"Gap" in completed solder joint between lead and pad

Electronics Forum | Thu Nov 30 16:10:05 EST 2006 | Hussman

Wow, why all the anger? This gap you guys are talking about is measured as "G" in IPC/EIA J-STD-001 (Chunks was there, but she failed to read the fine print). And almost all parts that measure G follow Note 3 which states "Properly wetted fillet s

SMT reels using paper for caps and have problems with feeder jam

Thanks Rob, Our tape does meet the Kemet spec but I am actually wondering if there is an EIA spec or something to compare to.

SMT reels using paper for caps and have problems with feeder jam

Electronics Forum | Thu Oct 27 12:58:33 EDT 2005 | gregp

EIA-481-B Max tape thickness 1.1mm (not including bottom and top cover tapes which can be .1mm max each) Of course a 1.1mm thick piece of steel will be stiffer than a 1.1mm thick lasagna noodle (already cooked). Is the thickness the issue or is it t

Are all tape and reels used in SMT required to be static safe?

Electronics Forum | Sat Feb 02 08:55:55 EST 2002 | davef

I'd don't believe that the reels need to be ESD protective material. The carrier and cover tape have resistivity and materials specifications. Start with EIA-481. In past threads on SMTnet, we have discussed problems in picking components that wer

unsure of what solder spec. your working to?.IPC/EIA J-STD-001C, Section 9.2.4 clearly states dull, matte, gray or grainy appearing solders are accpetable depending on your process and if the acceptability of the neaxt paragraph is met.IPC 610 and J-
