I don't know if this is the real answer you are looking for, but the EIA-625 and EIA-583 standards may provide you with the depth. http://www.jedecstandards.com/

Hover Davis is a good suggestion and they make outstanding feeders. Try EIA-481 for standards for tape sizes versus component sizes. This is pretty much the industry standard.

feeder pitch

Electronics Forum | Mon Feb 14 13:25:52 EST 2005 | gregp

EIA-481 standard allows the maximum pitch on tape to be 4mm less than the tape width (12mm width and larger). So it is within the standard allowances. As for how common 20mm pitch on 24mm tape is I can not say. I am surprised a 24mm tape feeder ca

Why 50 mils in 0805 package instead of 40 mils.

EIA standard packages have a variety of L/W proportions. EIA||Dimension mm (LXW)||Proportion (L/W) 0201||0.6X0.3||2 0202||0.5X0.5||1 0303||0.8X0.8||1 0402||1.0X0.5||2 0504||1.25X1.0||1.25 ||1.4X1.4||1 0603||1.6X0.8||2 0805||2.0X1.25||1.6 1111||2.8X2

Thanks Dave! What level of voiding is acceptable? Would you please let me know if there is an EIA or other industry standard detailing solder joint quality? I will begin researching the background information you provided. Thanks again for your kin

Feeder tape size

Electronics Forum | Fri Sep 27 17:42:35 EDT 2002 | russ

i don't know of any "handy dandy" but something I use is tape width minus 4mm for the max component size that can be fit into tape widths of up to 32mm. 32mm and larger have holes on both sides which would then be tape width minus 7mm. I have never
