When you get in to a 30 spindle lightning head or the dual and single beam 7 spindle flexjets from UIC, there generally really solid machines. The only flakeyness we have is with a GC120 (4 beams in 1 box). and of that most of the issues are purely b

Hi We found the misalignment sometime during SMT 0402chips. So, we made the pick up speed a bit slower then the condition was better however it was time-consuming and delay shipment. We r using Yamaha 100Xg SMT M/C and no probelm in mounting 0602 o

Davef is correct that's some nasty stuff. It was used somewhat in the 80s maybe the 90s it can clean a board however its total over kill for cleaning and it can harm you. I worked in a shop back in the 80s in the vapor degreeser days. and they used

I want to start an assembly that may require use of SMT machines such as SMT assembly, bond wire, Xray and PCB fabricator machines. I apologize I am not to savvy with the technical names such as the above but I just want something not to costly or e

Hello Austin, Have you tried to preheat the board or the contact area? Many times with the heat cured materials it will start the cure process and slow the flow of the material. Our Protect-R-Shield silicone product was formulated to be a much thi

We agree Evtimov that the best way to evaluate AOI is to test known good and known bad boards on a machine, preferably in your own plant. Be aware that I can run all of your boards and assure you that there will not a single false call. It's just th
