Quad4C's have their moments. If the price is right and you are aware of the machines limitations then you will be satisfied. The placement rate is slow, 1.2 seconds/chip. Don't buy any Quad if it has the CyberOptics Laser unit, the Quadalign unit is

Hello All, I've just bought a Quad 4c pick & place machine. It's so close to actually building boards, but just doesn't quite get there. I was wondering if there's somebody out there with experience of these machines that might be able to help...?

Hello Bobpan, Thanks for the response. 1. Function 30 gives me a consistent 182-185, even after nozzle changes. I can vary this by changing mod code 15 and I have been advised to aim for 90-110, but it doesn't seem to make any difference so I've go

I have a problem setting up the LAE on my Quad 4c. I set it up for 0805, and it seems to work, although it rejects a lot of parts, at least it places "most" of them. I tried setting up on a soic14, and could not get even one to pass. I believe I h

It sounds like the vac-verify is not working. There is a command on the hht to turn it off. When turning off your hht will show either 'idle' or enter command' without the V showing anymore. Maybe try the cntrl and vacuum or shift and vacuum. If its

Hello Marcelo, When you initialize the system in central controller...does it see mvs? Will a different job that you ran before work or does the same error happen? When do you see this error. You can email me at http://www.precision-repairs.com if y

Hello Bobpan, Thanks for the suggestions. Sorry I didn't reply yesterday as I'd gone home - I'm in the UK, so I'm guessing there's a time difference. Okay, I found the control to turn off the vacuum verify - it's SHIFT - SWITCH/VERIFY. Makes no di

My recollection of the 4c is fuzzy but I know that there's a ribbon cable on the head that gets some abuse when the head rotates. Seems like mine would eventually break at the crimps and I had to replace it a few times. Eventually I bought the parts
