Tape and Reel - IPC/JEDEC or other Standards ?

Electronics Forum | Tue Jan 23 17:48:17 EST 2007 | GS

for SMDs, try to look for EIA-481.1.2.3, or may be the new version EIA-200 if I am not wrong. Also IEC 60286-2 (leaded components like axials, radials,..) Regards......GS

Tape and Reel - IPC/JEDEC or other Standards ?

Electronics Forum | Thu Jan 25 04:47:19 EST 2007 | GS

see also the complete specific series of IEC-60286,IEC-60286-3, IEC-60286-4, IEC-60286-5,IEC-60286-6. All of those specs are realated to packaging specifications. Tape, reel,stick magazine,tray, bulk case,etc. Regards.....GS
