Hi, I off center idea we used when we started. Get a pasta cooker, and put in vapor phase fluid, and then use that. Place the product in the bottom of the inner pot, and then heat on a small hot plate. When the vapor cloud gets high enough and the

We have a Kaeser AS-25 screw compressor with Kaiser air dryer + cylinders. The system has a water catch prior to delivering air to the dryer that automatically "spits" to a drain. It's not fool proof - if the water collector gets overfull, it will

| Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there a

Designers love to do BIG copper pours for several reasons: * Maximize heat spreading. * Increase EMI shielding. * Laziness. The poor folk that solder the parts on boards HATE big copper planes near solder pads. During soldering, fat copper traces [

Hi, It seems weird that an automated pick and place machine at a board shop would not be up to NASA standards, but placing the components by hand would be. However most SMT will self center a bit, so if your close enough, you should be ok. You rea

Sr. Tech, youre absolutely correct that the X-Wagon (pancake) motor is the one which will do final positioning when moving to a programmed position. The X Axis motor in back of the machine is used for rapid traverse of the axis. I was thinking more
