Thanks you for the information LUPO, specially with component minimum clearance. I will also check the XY table for movement accuracy. What specific parameters do you check with your SPC charts. Thanks Crishan

QEs. You gotta love them. They live in a fantasy world of charts, graphs, and meaningless statistics. In most companies, they're part of the problem....and not the solution.

We don't know what your customer expects. If you do a nice chart of your third-party results that show a stable and in-control process, we'd guess your customer would let you slide without buying a BIG dust collector.

Hi everyone!! Is anybody have a chart or rule or standard for misprint. What I mean is if there is a way of saying if my print for some reason a switch 1%, 5%, 10%, etc, off the pad that is not acceptable. Thank you Yannick

Try looking at Chart Industries. They offer HASS/HALT chambers that are capable of reaching the paramaters that you are looking for. Will require a nitrogen supply for the cooling end.We had a 3000gal tank of liquid nitrogen to feed two chambers.

We're sorry not to have replied sooner, but we just lost track of this thread. The chart is from a course taught by Martin Tarr at the University of Bolton.

Hi all, If we are using non clean flux, what are the wave soldering parameters that we should monitor using SPC control chart? If not mistaken pre-heat is one of the important parameter that we should control.. Thanks, Sean
