Agree with WiIIR and also can recommend to play with vaccum pump RPM . Slower vacuum increasing have help me to resolve one problem caused by the vacuum (it was solder splash from BGA balls, but the reason can be similar to your case). Also check i

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 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

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...?

The conveyor on our Topaz runs for about a second then stops. Turning on conveyor manually does the same thing. While conveyor is turned on manually, disconnecting and reconnecting 208AC at connection board starts the conveyor for a second then it

We don't have the equipment to check specific gravity, we just assume what's on the bottle is correct and we've never had a problem. The stone sits in an open chamber, so there really isn't any pressure to check. When we vary the air flow, the foam

Try these things: 1. Do a function 30....your nozzle height should consistently be around 200 +/-20....but whatever number it does find it shouldn't change. (with nozzle on) 2. Most times its the z-bellows....an old z bellows that has a worn out spri

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
