If it is a very large factory you are doomed! You will never get the enviroment right someone is always going to be too cold, to hot, to muggy, to loud, I personally like the temp at about 72 F , humidity about 15% (ESD or MSD? which flavor do you w

Hi, This is a question for those of you who actually assemble components onto a board. Any idea what the "industry standard" is for the necessary First Time Pass Rate of products I should aim to? On pre-tested assemblies, should you expect to find

Hi Phil, There isn't one answer to your question. When dealing with really difficult assemblies that are pushing the process 50% might be considered OK. When dealing with run of the mill I personally would shoot for 98% or far better with a fast up

Yukim, Just another thought (way off the solder paste trail that you've been on so far)....Are the parts similar in thickness? The 4796 and 4797 HSP's have a closed loop function that compensates for variations in component thickness based on fe

If the only difference between the two products is the board supplier I believe thats where I would start, we had a similar problem like this two months ago and it turned out to be a faulty (thin) HASL layer which did not meet our print tolerance. T

Just make sure that you have it set up for 2mm advances (unless your parts are on 4mm pitch) also under your machine parameters, you may have to change the offset (Y only) for your trolley to be able to get to the proper pickup position. I used UFP6

no S**t, I was going into SMTnet to post a question, on : 1) what is the actual "physics" behind "Leaching" defect? what is the accurate desciption to define this defect? how to eliminate the general causes to this defect? If encounter, what work pr
