I'm using a CIM software (http://www.aiscorp.com/products_npi_circuitcam.htm) to import gerber files and produce pick&place programs and paper/paperless documentation. It's very friendly, useful and fast, but not cheap. I don't know any other softwa

| I am currently sourcing equipment to mount CSP devices. I have looked at the GSM Flexjet & also the Siemens 80 F series. However these machines only look for ball presence not ball deformation. Panasonic are the only ones who have a 3-D camera capa

This is a question regarding soldermask between pins of fine pitch devices. The majority of our production designs end up with at least 2-3 mils of copper thickness on the external layers due to blind vias, wrap plating requirements, etc. Our curre

Wolfgang, We also tried to find generic 'guidelines' for Moisture Sensitivity levels. It would be a perfect world, if you could say that all PLCC84's were level 4 devices. Unfortunately it is not that easy. Moisture sensitivity levels are

Handling requirements of all classifications of moisture sensitive devices is found in J-STD-033. It really isn't an issue for most parts unless they're going to reach reflow temperature again, which is unlikely unless you're removing a nearby compo

Hi, That's a good idea. I might head down the the 7-Eleven, and try it! I did not realize there is not too much to be gained by using refrigeration. We don't keep much paste in stock and buy it as we need it, so perhaps we should just keep it out r

You can't control what you don't measure. You have provided very little detail other than post reflow costs are high. What defects are attributed to problems experienced prior to reflow? Are these random or recurring defects? You will need to put ea
