You might wanna try a small reduction in your stencil aperture. For example, for a 30-mil pad go 26-mil square aperture with 8 to 10-mil radius on your corners. Also, look at your designs. Is there enough resist between your pad and ball? Another

How big are the parts? I've only seen a few parts that ever fell off. Double sided reflow is probably the most common these days The surface tension is powerful. I think the lower limit of temperature is what you would have to worry about with epox

Good morning, MPM AP25 we have is equipped with dedicated vacuum support only, no side snuggers. Also we had a lot of issues with fine pitch paste deposition due to this poor support. Vacuum support can�t fix wrapped boards properly causing a lot of

Grant, I beleive your problem may lie in the top side heater. Only 60% seems too little. I need to run my Soltec way past 60% to get top side wetting on larger part. You may want to have someone fix that. Perhaps Dr. Bocephus H good time budwies

For calculation let me keep future production in mind so for producing 1000 board/day X 110 component means 1,10000 / 8hr/day = 13,750 cph so I have to select a chip shooter between 15-20k cph. any sujested model of Fuji or Panasonic with this speed.

Screen printer, placement machine(s) and oven. You may also need a hand insertion line, selective solder or wave soldr and some form of electrical test. There are a ton of name brands that no two people can agree on. To get a better feel for what

Some have a bottom side adaptor plates with pins to make contact to certain areas of your board. The top side may have one or multiple heads that can move the entire area of your board. On each of these haeds is a pin like that from an ICT machine.

We are looking to possibly counterbore a coule of thru holes in one of our PCBs. We would counterbore the top side, and the only trace is coming out of the bottom side. The reason is to mount some LEDs flush with the board. They have some flash wh
