I think you are right. According to IPC-7526 section 6.2 says that using compressed air to blow out paste will damage the stencil, especially between fine pitch apertures. It can also broadcast solder paste onto other surfaces or personnel. I recomm

The Alpha metals Hi Check 500 is used to measure paste deposit thickness. The paste height is found from a micrometer reading determined by focussing a beam of light on a track adjacent to a paste deposit and then onto the solder paste. I've measure

Sounds like a unique request. Have the resistors been heated or are they old? For information about metal film resistors, look here: * ecadigitallibrary.com/pdf/CARTSEUROPE05/ECARTS0533_mai.pdf * homepages.eee.strath.ac.uk/~bwwilliams/Book/Chapter%

1) I had downloaded ANSI/ESD-S20.20-1999 from www.eosesd.org web site. I am not clear whether section 6.2.3.2 is correct. It states that " All process essential insulators that have electrostatic fields that exceed 2000 volts should be kept at a mi
