Depending on how old your through hole equipment is it should be SMEMA compatible. A copy of the SMEMA wiring diagram and protocalls can be down loaded from the IPC web site Under downloadable Doccuments SMEMA Standards. SMEMA : http://www.ipc.org/ht

We have started switching all our PCB marking from labels to Laser marking. We have a silkscreen patch put on the boards then use a CO2 laser to burn the mark off to produce the barcode. Our marking downtime has gone from an average of 8 hours a we

Hi guys HELP!!!!!!!!!! I have been tasked with working out a chart to show calibration acCuracy and that my machines are in control I say to myself I know they are cause I have no misplacement of fine pitch but this is not good enough for my co

Back-stepping a bit. If a profile is being used to: * Set-up the oven for a new product or trouble-shooting process, the profile should be taken with a solid contact to a solder connection. * Monitoring on-going stable and in-control process that re

You got the right feeling for that I guess but what if somebody else is doing your trick, is it still repeatable? Personally I wouldn�t trust that method more than the brushing. Did you try the dipping method ? The thing from Dave with this "card-com

G. I utilized the line computer setup print outs and transferred this information to a controlled document. Our operators are only responsible for operating the machines not programming. In our W.O.I.'s, I list the .la file, the setup. I list each

Thanks for the suggestion. We got the machine up and running yesterday morning. Turned out to be a power supply to the boards that control heaters and rails/conveyor. She ran great all day and hopefully will be a "hapy oven" from now on. Thanks a

How could you know if your printing process is capable or in control if you don't have a print measurement tool? Still, I suspect it's a myth that 60% of SMT defects are screening defects. Are there data behind these figures or do we just continue

Don�t your recent findings on soldering defects point towards less need for AOI? Besides that, I imagine that with 100% control and having only good prints being processed while the bad ones getting washed and reprint you will see this magical 0%. Sh
