| | | The machine is a Universal 6796 DIP inserter. The driver card for the X axis burned a couple of resistors and a trace, probably a couple of power transistors too. I had a spare card and put it in. Now on powering-up the machine, the X-Y tabl

Charles, I am using an Air-Vac PCBRM12 to selectively solder a 96 pin thru-hole connector onto an otherwise all SMT board. Cost is $8.6K plus about $300 per flow well (nozzle.) Went from a 6 minute cycle to hand solder the connector to 15 seconds o

Good afternoon! Typically, we normally recommend testing the pot, and adding either Sn/Ag or just Sn to keep it at bay. One nice thing about the solubility of Cu in Sn based alloys is that it should reach a theoretical upper limit of about 0.1%. I

Hi, hopefully I am too late, it is fixed and you are up and running. Have you tried MPM support on the phone? We have 2 older MPM's and the blow the driver modules in the bottom drawer on the back of the machine. There are different drivers for dif

Hi, so I was able to turn the machine on for a few seconds. It looks like the IC on the LCD doesn't have goo contact because it's very hard to keep the machine operational. I was able to see the table lifting for the first time; it was so cool! but t

If any changes in design is not possible and you have to solder it, it's a real headache, I know... I see only 3 options here that you can try consiquently: 1) Accurately profile the board and optimize a profile (go to lower limit of process windo

What I would look at is the chemicals being used in the facility where the complaints are. Flux/flux gel, IPA, cleaning agents, etc. Perhaps you should limit the usage to certain people only, who would be trained how to properly use these. Something

We swapped the Y1 and Y2 pc800 controllers with no change. We swapped out the UIMC III-I cards from another machine with no change. VRM amps all look OK, no errors. The machine moves the head both in the x and y directions during the zeroing attemp

Since you haven't received any useful advise I will throw my 2 cents in. I do not know this machine but in general what you describe is an axis that does not get it's home pulse in time. Many machines will have an in-range sensor that gets flagged
