We sometime use a temporary solder mask to "glue the parts down" if bean bags don't work Russ

Randy, are you baking initially for surface mount? These boards I'm talking about are just thru hole, so there would not be any bake between baking for part marking and wave solder.

Grant, try TEKA solder-bearing connectors. They have a "brick" of solder that reflows during reflow. They work great! Jason Gregory

Hi, I am looking for the IPC criteria hole-to-lead ratio. Does anybody know a practical way to determine if some holes in my pcb's do not get enough solder in the wave solder machine because an inapropiate hole-to-lead ratio? Thanks in advance! Hi

The shorts happen at corner of the BGA. The PCB thickness is 1.6mm, It is a PC motherboard with all thru hole connectors mounted on.The preheating is done using IR heater and the temp is 120-160 for about 70-80 sec.I am using ERSA IR550A

We use a chunkee trimmer in prep. Cut bend and form all thru hole parts before first assembly.

Valerie, Thank you for your reply. I have a quick question......when you converted to a double reflow process did you have any thru-hole parts on the assembly. If so how did you handle them....pin and paste? Thanks, mike
