We have used 2 lubricants in the past. The first was Isopropal alcohol, this has issues with regard to H&S but can be quite effective. Most of our product at the time we encountered this problem were washed in a semi aqueous system before shipping. A

Lower humidity: Pros: Helps with mositure sentative devices. Cons: 1)Paste exposed to the dry air during your porcess will dry out quicker. 2) Drier air promotes more ESD issues, i.e. more electrostatic generation.

Not the same machine... but I had poppet valve problems until I put a drier on my air supply.

Dano's confused. The boards are delaminating during soldering. The delamination just isn't immediately appartent after soldering. Stepping backwards. It's remotely possible that if the boards were blistering hot from soldering and then dumped in

Depending on your D.I. system, your maximum temperature concern may be at what temperture it returns to your D.I. system. Hot water may foul you set-up very quickly. As for maximum tempertures for parts, your biggest concern should be drier section

Our SMT production and storage area is air-conditioned, constant temperature is maintained but the humidity is not controlled , the raw SMT material is stored in a "Drier" cabinet, but since we assemble hybrid SMT and thru-hole PCB assemblies, the SM

Only use the shop air if it is clean and dry. I know from experience that one can get water and a little oil from the compressor in the air lines. We are in a drier climate with humidity levels in the 25%-35% range on average. All we do is let the

You should talk to your paste/flux manufacture! They will provide the best instruction for this. The norm is typically 130-145f, speed 2-4f/m I always push for slower… the slower the cleaner/drier (in theory!), if you have an ICOM, Omega meter, ionog
