| Thanks Steve- Here is the whole story: The solder balls are appearing all over, similar to a splatter. They are relatively small. We are using H-Technologies S-HQ no-clean solder paste. The stencil is 6 mil and the boards are running in a ABW

| We currently bake plastic SMT parts in accordance with the IPC guidelines for moisture sensitive parts. Because we have double-sided boards that are subjected to either an aqueous or semi-aqueous cleaning process, we do a 24 hour bake at 125 deg.

If it's really low volume I would only invest in a stencil printer and convection reflow oven to start with. If you want to go really low budget get a manual unit such at one from Transition Automation. Make up some really good shop aids and have s

| Cpk's on top flight ovens (e.g., Conceptronics, Heller, Electrovert, Vitronics) vary wildly, from 1 to 2+, between different supplers. The suppliers don't seem to understand Cpk's. A supplier's rep whose oven has a Cpk of 1.0 told me: | 1. Cpk's
