Why can't you place the entire job the same day you paste it? I can. But setting up and properly cleaning the stenciling machine takes 2-3 hours. We only run one shift. If we do that every day we're spending most the time on setup+teardown. Much

Or try : http://www.sipad.com/ I think sipad is incredibly cool and would be the perfect solution, but is way too expensive. We're paying $0.80/each for four-layer ENIG boards, 50cm^2 with 0.125mm trace/space and 0.8mm-pitch LGA landings in lots of

Other areas you can focus 1) Find out alternative chemical and solder materials for lower cost. 2) Set high power consumption machine (such as Oven and wave) to idle mode when not running to cut electrical consumption. 3) Reduce the used of N2 gas.

I measured the temperature rise when I built the unit and it has a nice linear rise in temperature over the 3 minutes. I have used the Quikees before. The galcon gas stinks and must be evacuated. The galcon is expensive. The galcon is a perflourocar

To all good suggestions I will add a few other thoughts: 1. Check PCB design(attached). THis mask clearance there is designed so you have some gas escape plan- verify if your PCB design follows that. 2. You can have a long soak reflow profile to re

1. Migrate to horse-shoe pad design. 2. Verify your furnace is level. 3. Verify your chains are not jerking around. 4. Speed control for fans / gas amplifiers are correct or normal? 5. (this happended to me once) Make sure you don't have any f
