What thickness is required to process a double sided board with white tin? Is there an IPC standard? If rework is necessary, what is required?

I would use a spot solder machine. If not, why not spray the mask onto the board? Use a Camalot machine or something similar. Using a stencil over placed components wil yield a thick mask - right? That's why I'd spray.

The manual gives you a fair idea here. Reference for the Yamaha manual is THE6006 - I don't know if Philips is the same. Cause is either overload or overcurrent. The manual suggests that you can tweak the trimmers on the driver board but these are us

Tx, Your spec limit is the point at which you expect to see a failure. In other words, what is the probability that you'll see a short when you have .008" of solder paste? What is the probability that you'll see an open if you have .004" of solder

Let's examine some scenarios: What if... ...No solder sample available and you must profile a "live" board (rules out epoxy). ...Lead free build (rules out lead bearing alloys)

Are we talking about reflowing the two boards together after the one gets the solderballs reflowed onto it?
