We run a "no clean" soldering process, class II primarily, conformal coating using a Humiseal acrylic coating, applied by machine and by brush. We have seen very few coating issues in my 10+ years from contamination by body oils. We are not using glo

I am looking at purchaseing a full convection bench top oven from OK Industrys. (Model JEM-310) It seems to have all the features that we will need for low volume production runs. It has a Nitrogen input option, and I am intrested if anyone on the fo

Dave, Thanks a lot; you truly are a living database. I will need new spectacles missed the eutectic alloy in table 4.8 of the Klein Wassink book.

We manufacture low volume, high reliability assemblies (class 3) that are conformal coated. Up until now we have been cleaning after SMT, then after through hole, then immediately prior to coating with test, formal inspection, etc. between cleaning p

At reflow an inert atmosphere is used to mitigate the occurance of oxidation, to me the decision weather to move from an inert atmosphere is based on several things ; PCB surface finish - are you using a HASL finish, OSP or another surface finish and

Hi, I am new on this, I want to ask you what is HASL finish, OSP, FPY, ppm. About to eliminate the Nitrogen in reflow soldering, a listen about one solder paste that no requires Nitrogen, the solder paste is called Indium, I don't know if this is tru

The use of nitrogen will not play a role in even heating of the product. What it will do is make a marginal process look better or give you a larger "process window". The need for nitrogen depends upon several factors. If you are using commercial p
