Have any of you ever gone from using Nitrogen in your Reflow and Wave solder process to using only compressed air? No Clean users only please. I'd like to get away from Nitrogen if it makes sense.

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

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

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.

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

Hi smtnetters, I�m looking for reference material preferably graph�s displaying the viscosity and surface tension vs. temperature for standard Sn63 Pb37 alloy. Plenty of reference material is available on pure metals but can�t find anything on the

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

Luis, Go to the library on SMTnet and you will see Standard and Terms. Select that and you will be able to download the terms and definitions for SMT assembly. It is very useful. Of the terms you requested, only FPY is not there. I was curious a
