One of our board vendors recently switched their stencil design to home plate apertures. Since the change the quality and yield of their PCB's has went south, Could this process change be the cause?

Home plate apertures are designed to reduce or eliminate solder balls that occur when placing a chip and reflow of the solder. This aperture type is usually desired when processing with a "no-clean" solder paste. The design of the aperture is usually

Hi, We have several fixtures for GenRad 228x tester and would like to change sensor plates as they are quite worn. The problem is that 3 fixtures have different plate sizes for the same IC, side length is 10-12mm. What would be the best size for sens

Home plate or bow tie?

Wave solder flow over back plate

Electronics Forum | Wed Feb 20 18:21:49 EST 2013 | caurbach

A question for all you wave experts out there: We run our wave with a constant flow over the back plate. I know it's recommended that we set the back plate so that the solder sits just at the top of the back plate with surface tension keeping it fr

Caurbach, Higher preheat and longer dwelltime will fix your problem.

Wave solder flow over back plate

We agree with all of what Patrick has said. Hopefully your equipment is capable of the ideal setup you describe with no back flow until the product hits the wave and then back flow until the product emerges the other side. One other reason to strive
