| We've noticed that there are many different recommendations for pad sizes for various SMT parts. This seems to vary wildly from manufacturer to manufacturer for the same case sizes. Is there any standards that can used used to specify these sizes

We have been pretty successful with screen printing glue, however the smallest component we now glue is a 0805. We had many problems using our Gemini II to put down glue dots for a 0603, so we altered the pads to do double-side reflow. As our own int

Based on your research, what is the pad and stencil design that you recommend for 0201 assembly?

Hello! I have a strage problem, we made some production with uBGA, BGA, 0201, 0805, and other type of component. We didn't put the uBGA and 0201 and BGA on the board at the end of the line we look a our solder joint and surprise the solder made a

The results from an experiment comparing 27 different combinations of pad dimensions concluded that the pad design with 15 mil pad length, 12 mil pad width, and 9 mil pad separation produced the best assembly yields. A 5 mil thick laser cut stencil

A good place to get the data you are interested in would be Philips CFT design guidlines.

What about the material of the stencil? Nickel formed? stainless steel? even more materials are available, some with different ways to form the apetertures.
