We have a GSM1 with version 1.4. The machine has the old VME chassis. So to upgrade the software (to use enhanced component setup) the VME chassis has to be upgraded. We had UIC in last year to look at this and they would upgrade the VME and software

Universal use to sell a a device, machine mountable, that could place this connector. I am not sure if they still sell it... It has been 3-4 years since I saw it in action. The upgrade would force the boards stops to remain in the Up position while

So would the proper technique be as follows: 1. Grounded operator picks up PCB from ESD rack and attaches a 1meg(wrist strap cord)shunt to ground to a grounding surface on the pcb. 2. operator sprays conformal coating onto pcb using a spr

We have had issues for the last 4-5 years with converting our stock from leaded to ROHS components. We are a CM and have customers who want all ROHS and some that are still leaded. The problems we run into are when we intrduce a new ROHS component wh

Check the following: 1. Cam Motor cooling fan. Check if the fan is running or not. Clean the cooling fan cover. 2. Check the oil coolant control box. Check all the contactors does not trip. 3. Check the circuit protector M1CP8, M1CP9 and M1CP10. One

I've just seen your question because I list this site rarely. It can boot usually from C: hard drive, we have 4 Omron AOIs - brand new (RNS & VT-WIN2),theoretically one computer can boot from different disks, it is set up in the BIOS, there are some

Does anyone know of fully automatic pick and place machines that can pick up parts either from small pieces of cut tape (i.e. 0402's, 0603's, SOT's) or components loosely arranged on a tray (not ic's that are in matrix trays)? Application is proto

First piece of advice: build the board as you would any other board. Probably, you will be surprised at the holding force of the solder of the connections of the BGA, because the surface area of the solder is very large compared to the weight of the

Hi Dave, I haven't tried the Probimer yet, but the Taiyo ink didn't hold up too well. As a PCB fabricator, finding a white soldermask that has good trace coverage and survives 4X solder immersion (HASL) is like the holy grail of white soldermask.
