I had the lurching issue...turned out I needed to readjust to cog wheels on the exit side of the oven. The cogs had slipped, and the chain was actually getting caught in the teeth...to the point that as the wheel turned, the chain would stay in it i

Might want to check to see if the weight of your part has increased. If it has increased, you may not have enough surface tension to hold the part on the board. I am assuming you already checked that the component isn't getting hit by something in

pick/place head won't travel over the LED's, then you won't be able to proceed. I wasn't clear in describing my board layout; It is LEDs on one side and SMT components on the other side. I don't think we can get around the problem of stenciling

I've never seen them used or even heard of them being used like this but you might want to look at http://www.sipad.com/ You will still have to work out other issues like how to keep the SMT on while you wave the LEDs. Maybe you can get these board

Wow. Never have, never would, but that doesn't mean it couldn't be done. Mostly it just seems impossible to design a carrier clip that could hold both well...more likely it would hold one well and the other poorly, or both poorly. Anyway, is there

Has anyone experienced intermittent communication issues with GSM/GDM and PCT conveyors? I have an intermittent issue where sometimes I would hit the ESTOP on the PCT conveyor(downstream) in order to get the board to eject out of the GSM/GDM. I have

I want to get a collective opinion from the forum... I was always under the impression that Humidity at SMT can be a disaster and can cause solder balls... But what about at the Wave/Selective solder? If every board or almost every board has solder

Dave, I'd be skeptical too, with that response! I've got a Culligan DI system installed here, and it's got it's own resistivity test meter. When the light goes red, it's time to call and get my resin changed. It's worked out pretty well here. Ba

Hello everyone; I was wondering if anyone has/knows where to get, VIP98 FCU calibration procedure. I know its a long shot but need to calibrate a few ovens and we�d like to see if its possible to do this in house, as we have a calibration lab.

Joris, Yep, very common to have those small blow holes in lead-free alloys. We used to get them very consistently on white-tin finished boards, and less frequently with gold finished boards, for what ever that is worth. IPC-610 actually allows t
