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

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

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 Chuck, let�s say it the other way round. We use noclean since I can�t even remember without nitrogen and all of our subcons do with no known problems. The processes are adapted to it and no complaints are heard up to now. That is related to our pr

We own a BTU Convection Oven. Nitrogen helps make shiny joints since it reduces oxidation during reflow. It has helped us solder marginal solderably boards but otherwise if "pretty" and "shiny" is a requirement I would consider it. It doesn't turn

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
