Absolutely, 0402�s are no problem and should not require any special modifications. However, you will find, that not all 0402�s are the same. I have users, who created 5 different GF-packages with different dimensions and light contrast. With small

9.0. In it's spent form (from a batch cleaner) the cleaning solution is at a pH of 10.1. Luckily, we are setup with a holding tank and have an oppurtunity to treat the stuff before sending to drain. My question is, what is the easiest way to adjus

The format is X,Y Theta of the component center for all placement machines. Gerber data can be useless, unless you have the reference from pin 1 to the component center. Some machines offer a CAD convertion tool. I don't know any machine, which can
