Get two connectors to fit the SMEMA 1 connectors on either end of the machine. Need only two wires on each connector going to momentary contact sw. Input is pins 1 & 2 to switch and output side is pins 3 & 4 to switch. If this doesn't work then ch

Did you just change anything on the Exhaust?... even if the change was adding something else to the main exhaust trunk, if you don't have each item seperated. Although CFM changes should not effect the Blower Speeds or the Zone stablizing time, since

ICT and specifying PCBA testing

With TestJet technology, if we want to test a 64 pin BGA, would we need probe access to each net of the device to get full coverage? If not, would I only get coverage to the pins that have probe access? In a nut shell, How exactly does it work?

Power up your machine and look at the vision card. If it has a red light then there is a problem with it. 20k is way to much to spend to fix this. I've sent out two cards for repairs in the past and got them fixed for $2200 each. If you want more inf

Hello, I have been tasked with finding a solution to rework 242 boards that have 34 incorrect 0603 resistors placed. These resistors are placed throughout the board and are surrounded by other SMT components. If anyone can advise me on a more time

Multiple Resistor Rework

Electronics Forum | Mon Aug 30 08:57:54 EDT 2010 | stevezeva

Hi Stephen, Once they've been soldered down, you're stuck with doing touch labor on each and every one. But you might be suprised how quickly this can be done with the right tools. Are they all the same value resistor? If so, that should make things

Seems we had similar issue years ago with our VIP 70. There are a series of 2pin axial fuses on the panel with the SS relays and contactors (I don't think it was over the FCU). Check each fuse with a meter; replaced ours and the e-stop cleared and th
