We have solved our MCSB problems by using standard homeplate designs on all of our resistors and caps. I use a 50% taper and have achieved great results with 0402-1206 parts using both tin/lead and SAC305 paste. We use Amtech paste.

As an employee of a Reflow Oven Manufacturer I can only make suggestions on the oven portion of your process: As I was reading through your posting I started wondering if you are using a convection or IR based oven. If you are using Convection I woul
