Thanks, guys. Hi Larry, long time no "see". Dave, 60k dots out of a Camalot 2800 does not a "Dispenser Boy" make. :P I'd print them in a heartbeat if the proximity to radial leads didn't necessitate me placing radials first. Oh, wait, I'd have to

Can't seem to get a reply through (watch, they'll all show up in about 15 minutes), so I'll try this. Thanks guys. Hi Larry, long time no talk to. "Dispenser Boy"???!! If they wanted me to build them (instead of the overseas CM) I'd print them my

Hi Well I don't agree with Mr Fox. Cp and Cpk i.e Capabilitiy studies always yield good results and add vigor to the engineer and the process. You might want to hire a consultant or go to some classes to make sure you do this correctly for your si

Hi Enrique, I don't remember all the energy levels that make the techniques you or your associates are using, effective. Each energy level yields information that must be understood is the best that I should give. HEY Based on my comment, does this

One addition to Dave's comments.....my previous experience yielded one key observation about the differences between ISO audits and GMP (FDA) audits: ISO audits were to establish that you had a documented process, complete with procedures, establishe

Agree with Joe 100%, we recently brought one in from Malcolm for trial, this company had not practiced viscosity reading or anything in the process, the trail run was a great improvement in print, consistancy, deposition and formation of the solder b

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

Hello! We placed quite a few of 0402 with our CP3 using 0.7mm nozzle with the same feeder as you had. Pick up can be adjust and calibrated, but that is not the problem, I agreed with you on that part. The trick is you have adjust and play around wi

I also agree with Russ - we use step stencils when we have to but generally try to avoid them because the print isn't as consistent as with a single thickness stencil. Many of our products are for harsh environments so we do a lot of thermal cycle a

The use of nitrogen in lead free wave solder operations is primarily used to reduce or even eliminate drossing of the solder, thus improving solder yield. The higher priced lead free solder makeup (Cu, Ag) make this a more economical proces than the
