I am happy that you work in a shop that can build boards right the first time on a consistent basis. Unfortunately, I would say that every place I have been at, we have had a hard time meeting class III standards day in and day out without some kind

As far as the buttons go, White = pause for inspection when depressed, lit when active Green = pass after inspection when lit you need to press the button, when flashing its waiting for the upline machine, Yellow/orange = when flashing indicates

It sounds to me that it's a heat transfer issue. The solder is only bonding to the lead on not the barrel correct? Does your selective solder equipment have any type of heating source? Can you "dwell" on that particular joint? On some of our products

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

Hi, If this is sworf from pcb let say after routing of panel and sworf is attach to pcb cleaning with ultrasonics does not help unfortunatly. one of new cleaning technic which is worth to investigate is "snow jet". this is used during deburring and

THe question is - does that happen on all of your programs or just in one program? If it is just this particular board, it might be some softwaRE limit issue. If it happens on more programs it is a hardware issue and it could be one of the following:

Hello, Looking for a solution to silicon conformal coating wicking up into connectors. We build IPC-A-610 class 2. We are using a PVA 650 with Dow Corning 1-2577 conformal coating. We have solder joints that must be coated 1.25mm from the connecto
