The best is, create 2 different profiles for each PCB type. Then segregate or separate them and do not let them run together in one line. Switch to the proper profile settings each time you change to other PCB type. This is the best. Each PCB materia

The thermal recipe you use is dependant primarily on the solder paste that you choose.

Hi to all, I'm facing a soldering problem with one of my series of Product, since we were using a two different kind of PCB 1.GE(Glass Epoxy)2.PP(paper phenoline) in later PCB if i will use the same profile of the GE then it will get backed more & i

Snehal, Look at the spec sheet for the paper phenoline PCB. Look at the max temp. If it is at or lower than 183 degrees C, here lies the problem. If it will withstand higher temps at a shorter durration, you can possibly speed up the belt but like D

Hi Davef & C Lampron. Thanks for your reply. since i'm using RMA9086 62/36/2 Cookson no clean flux paste.so what do you think if i will switch on to the paste without no clean flux for PP board is there be any chance that i get a +ve result. Awaiting

Hello again.... I have been reading up on profiles and how to set them up for different results. I now have an upcomming job with some strict guidlines on reflow. I was wondering... if I were to email a pic of my desired profile could someone out the

We're used to placing the theromcouple on the solder joint and securing it with thermally-conductive UV adhesive. It's quick & easy to apply, and I've only seen a couple degrees difference from high-temp solder technique. Thoughts?

You can, and for small parts you probably won't see much difference between body temp. and lead temp. For QFPs or PLCCs there will be a much greater delta, though. I'd be more concerned with the small surface area you're making contact on (spherica

We recently decided to try using a different source for our bare boards to save money. On two different batches of PCBs now from the new source, we are seeing beading including some serious enough to short out underneath 0805 parts. We have never re

TK, Hope you got it right only for this round of assemblies. Well, passing through a Reflow belt is not an ultimate process to dry circuit cards & take out moisture from Solder finished layers. First of all, if the packs were not unsealed (even s
