I have an adhesive dispenser in my workcenter but I rarely use it. I've replaced this process with wavesolder pallets for bottom side PTH soldering, ocassionally gluing parts left exposed by the pallet. So I was thinking of selling the dispensing equ

Trying to place PTH components with an SMT machine is possible but maybe not plausible. Would you have to buy specialized tools and equipment for the job ( gripper nozzles ). Are the machines you have capable. i.e.. Would you need camera modification

Labeling of SMT solder stencils

I'm currently working for a OEM that has 700+ stencils in house and we received 30 to 40 stencil a month. We recently switched to a no clean process which is causing the stencil part numbers to disappear from the stencil frames due to the saponifier

First question I have for you is: Are you assuming that standard precautions are in place at your facility to minimize moisture content i.e. air- deionizers, vacuum sealed packaging, humidity control in storage and manufacturing? You do not mention

BGA dropping off underside of board

Electronics Forum | Mon Aug 13 05:39:31 EDT 2007 | saaitk

I am building a double sided SMT board. On the first side I have a 405 ball BGA. When we build and run the second side through our reflow oven on about 25% of the boards run the 405 ball BGA on the underside of the board has fallen off. About 80% of
