The problem about covering it with glue (without using solder) is that the components might dislodge by a miniscule amount underneath the glue. So maybe the contact points will disconnect. I'm not sure if this will be a real problem, but if so it wo

If it is instructed to ship lead free product to customer, then low temp lead free solder paste can be considered. For example, Viromet solder paste from Singapore Asahi (peak temp is between 220 to 225 degree C).

1 - Too messy, parts already come in nice easy to use machine compatible packaging, tapes, reels, tubes and trays. All you are doing is adding an extra step and complication. A key production aim is to reduce the number of steps. 2 - BGA - a chip wi

Ron, have a look at http://www.fda.gov/cdrh/dsma/cgmphome.html It would be a nightmare, if your plant is not structured to support it. It's a huge pain in the fanny even when you (alledgedly) are. I'm not sure what you're pursuing, but if you're c

Sorry 10 days passed before I replied. This happened and that happened and I completely forgot about this forum. But here's my explanation: 1. How to get parts on the board? This is a very good point, and I totally understand why you believe I hav

If you study how the process is done now, it isn't that different from what you describe. Instead of glue, we use solder paste, and instead of spraying it we screen print it. But not that different. For feeding boards we use conveyors instead of rubb

Andres, I think if you were to understand the process a little better you would realise the many many problems you would encounter building even very simple things using your method. Even 30 minutes watching Youtube videos of current machines might h

The way it works is the liquid solder immediatley cures (or should I say burns) the WSOL where ever it touches it. This hardens and keeps it in place and protects whatever is under it. Some of the WSOL falls of in the pot. I am suprised that the burn

If the mask is not cured and is coming off in the pot I don't see how it is protecting anything. If you want to mask something fast you need to use tape not liquid mask that requires cure. My $.02.
