Leon - Remember for a CBGA you will need to use high-temp solder balls. IBM can supply the recommended solder paste (eutectic) volume. Glenn Robertson

Our next plan of attack is to dog-bone the solder aperature. By reducing the width of the solder paste at the heel, we hope to slow the flow up the leg of the pin while the temperature of the pad catches up. We have boards that were HASL ...

Consider the profile recommended by your solder paste manufacturer to be the starting point to begin tailoring ramp rate, dwell times, and temperature excursions to meet the requirements of your boad design, the capabilities of your components, and t

Hello, Dr. Ning-Cheng Lee The melting point of solder PB-Free its to higher do you now the lower temperature of an PB-Free and its constitution. Its true if the solder paste have in its constitution a Bismut component the melting point its lower?

Is the temperature the only drawback when reflowing components other than connectors? for example caps, transformers. Is there a problem with the soldering quality if the body of the component covers the solder paste?

Ted, We've tried using dispensing systems but without success. We either use stencils or bump the pads with solder. Stencils are messy and time consuming, but seem to be the best thing going. Jeff Ferry Circuit Technology Center

Joe: Both dpmo and measuring solder paste height are good topics to practice your SMTnet archive searching skills. Yes, some microscopes can be used to measure solder height. Good luck Dave F
