We just bought a MVP Supra M machine and have put it under power but can not get the PC system to power on. I am following the power up procedure in the manual. Under power the conveyor controls work and the UPS backup turns on, but holding the key i

I read a few posts here about resistor in led applications. The thing is, the resistor has clarified as this shows:was always use with a power source delivering a higher forward voltage than the led could tolerate(ex: a 9volt battery hook up to a 3w

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 table move

As in more dwell? We see the same problem with through holes connected to power or ground planes. The solder reaches the plane and stops. We are having our boards re-designed to increase the thermal relief and expand the hole size. We are also tr

Have you done a post-mortem on the blown fuse? Assuming it is a glass fuse, if it is all black around the glass then replacing the fuse will be pointless. (the new fuse will just blow again, making a black mark or BLACKER mark all around the glass)

hi, the last post on pad cratering dates from 2012. We have (likely similar) problems with a RoHS 783 solder ball BGA size 29x29mm^2 (organic package BT), pitch is 1mm and solder ball diam is 0.5mm the field failure is after 12 months, almost exclu
