I WAS a huge fan of fully coded part numbers. One customer had some part numbers that must have been over 30 characters(maybe some over 40) long and some about 6 or 7. PTH parts can be the worst because it seems like back in the day a 1N4001 was a 1

Re: Questions #2 Are you having solderability problems with that arrangement? Sounds like problems could be solved at the wave solder. If the customer has already spun pcb then sometimes for low volume it would be easier to correct the problem at wa

For the Resistor Network Array SMT 0402- 8 pads I'm using a Stencil 5 mils Th. with the next appertures : Corners-biggers pads: 24 x 12 mils Center pads : 9 x 24 mils This Appertures are working excelent for the RN's that his appertures are parallel

Nuts to that! Here's the right way todo this. I generally take a bill of Material and go line by line and charge accordingly. If there is a smt cap I charge 2.3 times the amount I pay, unless it�s a bigger than a 1206, then I charge 3.1 If it�s
