Valerie, Thank you for your reply. I have a quick question......when you converted to a double reflow process did you have any thru-hole parts on the assembly. If so how did you handle them....pin and paste? Thanks, mike

Sorry Duckman, I am not Valerie but I am going to answer you with what we did and do. We will either pin in paste or utilize selective wave pallets. Russ

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t

I have done that also, It does work well. One issue we had was that the mask didn't come right off during the first wash cycle since it was put on much heavier than the mfgr suggested (.01"). We had to soak them in some water first to soften it up

Mike, To answer your question, Yes we have thru-hole parts on the boards that we converted to double-sided reflow, we use pallets to select solder the leads. I suppose Masking would work, but that's using a lot of mask. Can I ask, whats preventing

We have a board that uses 0402x4 RNET packages that we are having a difficult time getting to solder consistently. Paste deposition is fine (using AIM WS353) and profile is dead-nuts. I'm starting to wonder if this is something that we're just goin

I need a little help with RF and Rogers 4003 board material. My background was in digital and now I need to set up a new line to make small RF products (.5" x .5" or smaller). I want to find out about board platings, finishes/maskings and reasonable
