Hi Up above in his operation / process description after a call to Locktite and then my note and then your note, we may have found the problem. One never knows at a distance. It appears he is striving to do soldering/reflow first and then concurren

I have had a look at what Bob Willis say's and the answer to my problem is not there. The paste we are using has a very high viscosity and I beleive that if we reduce the metal content to less than 90% it will solve the problem. The problem is parti

One easy and often over looked step is to call out IPC-6012A compliance on the PO. You will also need to call out the class status. If you get in an issue regarding quality you will have a resource to fall back on. Sounds simple but ask your buyers

1. First and foremost is paste alignment. If you start out of the gates with a bad paste/pad relationship, it will be nothing but problems down the line. AOI is not required, but dial in the alignment, QC if necessary, then introduce the boards to

Never heard of Bareco wax. Check with your press supplier. They'll have the dirt on this carnuba oil stuff. I do question replacing ENIG with HASL, no other changes. HASL is going to fill that hole alot more than ENIG. Certainly it will displace

I had the same concern. The connector pins are gold also. I am waiting for a response from AMP to supply some of this wonder wax. I can inspect the HASL fabs for proper hole diameter, but I do not have a warm feeling I should be getting involved with

Hi http://barecowax.com/About%20Bareco.htm You will notice they have a lot of products. After you get from AMP the actual Bareco lubrication product they are recommending for their product application make sure you know what cleaning method remove
