Verify your aperture reductions in the stencil. Are the solderballs always in the same location? Same size & shape? Is the solder leaching through plated thermal holes from the opposite side of the PCB? Are you using stencil apertures designed to min

| | | Does anyone have any experience with EKRA screenprinters? I am looking for a semiauto screenprinter and I came across this brand. My local rep says that they are fairly new in the US, so, it is hard to get opinions on the machine. I am looki

Hi Samson ! In order to give you more detailed information I would like to know what your component range is and how many boards you supposed to do. Panasonic and MPM are a good choice, however, Panasonic has not many P&P machines on the U.S. market,

You�re correct, many of us recognize that problems in paste deposition are the source of the majority of SMT component defects. What would you say that the portion of the "51 to 72% of all solder defects are the result of screen-printing problems" t

Try using a contrast filter. This seems to help. Also on the camera it self there is a white level control. Adjusting this may help. The bad thing is it may affect all your other profiles. Some times an easy fix is to have a screen print mark close t
