Yes Nancy when it comes to PLCC or anything bigger then Som, so16 we too use vacumm pens. The initial comment was regarding passive compoents. As for the fristch semi : the vision system is the only thing that is still being used for: 20 mil QFPs

An NDS9936 is a SO-8 MOSFET since this is a SO-16, its likely to be 2, easier enough to chack by compareing the pin patterns. It is what you would expect on a board which is remote on a car harness, and has a control circuit. sarason

We have A V-Tek using pressure sensitive cover tape but the only success that we have found is with SO-8, S0-14, SO-16 anything wider and the tape pulls apart when on our feeders. ANything over 16 wide is not recommened unless you get a heat sensitiv

PCB is 12.25" x 4". There are large MOSFETS on the board. Two large Electrolytic Caps. Two Large Multi-Layer Ceramic Caps. 15 C Size Tantalym Caps. A fair number of IC's, (SO-8's, SO-16's). No BGA's or finepitch of any kind. The board is double sided

For package shapes/names I would recommend using manufacturer names. This is much safer than coming up with descriptive names like QFN32_5x5 as there are multiple 5mm 32Pin QFN shapes even when pitch is the same, this makes it safer to use a name in

I am involved in the purchasing decision (Technical side) of which placement machine to buy. One of the criteria we need to specify is how many feeders, and what sizes. I have a provitional parts list of a job that we are most likly going to build. T

Hi We have a problem here in the company with AOI system, most of the problem is lifted lead on qfp components.We are using SAKI BF-planet-x. Most of the defects like mising components 603 or 402 are no problem but if it comes to lifted lead even

Hi Will, it�s possible to use second reflow for second side components without glueing or use of different alloy solders. Although the first soldered joints become liquid during the second pass the parts will not fall off as long as their weight does
