Jim Blankenhorn [www.smtplus.com] has the best understanding of designing pads for real life. That�s because he designs them like he wants to design them and doesn�t negotiate with a committee of thousands for an IPC standard. Consider doing this

Piece of cake, our sencil design software not only automaticaly mods the data for all component pitches but can apply anti solder ball designs ( homebase, form4 vnotch etc). As an added bonus it warns when the side wall to surface area ratio exceeds

Hi aj, Pete is right, there are several variables that can affect your quality when it comes to stencil design. A good idea is to have a stencil made with various designs incorporated into it. A lot of engineers like the reverse homeplate design.

Can someone lead me to some articles or technical standards showing formulas/design criteria for thermal management in a BT BGA? I need to be able to dissipate about 4 Watts, and am having trouble finding information on how to calculate what our BGA

Hi folks, Is anybody have an experience in stencil design for CCGA ? Currently, I'm running with 5 mils thickness stencil and I encountered that there were defect on contact after reflow soldering process. Appreciate your help ! thx..Jack

I am having problems with D-Packs shifting during reflow. Does anyone know of a good aperture design to solve this problem ? Possibly bow tie.
