| DO you know of an Industry Standard that describes solder paste geometries requirements? | If it were only so! Most people I work with, because of so many variables concerning solder paste, its composition, particle size and shape, and application

HI, i work for an EMS company and i got a few remarks on the solder mask question. In the manufacturing of PCBs there should be no difference if they use other color solder mask, but in the production of electronic assembly it could make a difference

Sorry, if my first comment was a bit offensive against PCB manufacturers (it was not really intended :( ). We have already discussed the above mentioned issues with the manufacturer, and they stated, that everything is within specification... (and y

Thank you Graham for the response. The particular BGA that we currently Bake is a Level 3 BGA, which means the BGA will expire in 7 days after removal. We are currently baking the BGAs once a week for the problem described above. These devices are u

I had the opportunity to spend time with a demo and one on one with the inventor of the Ersa scope inhouse a few months ago. I see the scope complimenting X-ray inspection but not as a substitue. It allows you to view attributes of a solder joint t

In approximately one month I am installing 2D at our DEK print station. We are going with the basic (cheap) software options and 2D camera. After it is up and running we will determine if it is indeed useful. At that point we will decide on the adva

Bill S. is correct on the positive effects of the Smartsonic 440-R SMT detergent. We have been using this in conjunction with a Smartsonic 4200-2D ultrasonic washer that is equipped with a tank heater set at 100'F. Our suggested process window to p

Caltex or Ersa type system is good, Caltex prisms, necessary for looking underneath the BGA can be crashed easily when looking under low profile or Micros. $40-$110 each depending on the availability and who makes 'em. We have 2D and 3D X-ray avai
