My Dek printer "forgets" the speed setting after a few passes and reverts to a faster speed thus screwing up the print. If you edit and change the programmed value and save it, all remains find kind of like refreshing the memory. Any suggestions, I

Hi, If you're thinking of a new machine and the volumes are not very high, I think Assembleon's OPAL XII should be the best fit. It can handle VERY LARGE boards upto 25.5" x 17" (with single pass) and 25.5" x 33.5" (with double pass). However for th

Our solder paste machine has a squeegee problem. After passing over a board, the squeegees don't go all the way back up to their origin state. Then we are getting a timeout error and have to return the machine back to its origin (manually), and pass

Unless you've got an extremely agressive cleaner, the epoxy should hold the parts during the delay time. That's their job basically. We ran reflow first pass, glue parts, then wave solder second pass. There were potential delays between adhesive b

Hi guys! We just had our SnPb wave solder samples tested. However, the papers just gave us the contents and the percentage of each contents found with the sample. Does anybody know the passing range and/or paramters of the following elements: Pb, Cu,

Also consider electroltyics as some brands can only cope with one pass through reflow, 2 max. In Vapor phase 1 pass max is typical. Although depends on makers specs and what they say the device can withstand. main issue is Dielectrics get damaged , c

The machine sees the nozzles and thinks that the part is there. The lighting on the machine is in desperate need of an upgrade. Constently having to tweak the GF's to get components to pass vision. We share a line computer between 2 lines and the cam

Hi, Does anyone know what the placement success percentage is for lead components And the placement success percentage for lead free BGA components. We place many varieties of BGA devices, over 100 different size parts, from 1000 pin BGA to small 4mm

Good to hear, thanks for the response. Once you get the program fine tuned, do you generally have most boards that are inspected pass with the green good screen or do you generally have to review a few defects? OF course this all depends on passing r
