Curious. Tell us more about: * Murata solderability protection * Solderability protection on the caps used to replace the Muratas * Reflow profile used with each of the two pastes * Differences in the two pastes

A small SMT line? I have conections for a New screen printer (MPM), Essemtec Placement machine, and Reflow oven (Electrovert) for $100K Let me know how interested you are. Caldon W. Driscoll ACI USA 610-362-1200 cdriscoll@aciusa.org

How can you determine if a SMT component will have enough surface tension to stay on the PCB during reflow process? I understand there is a formula that will provide this information.

Hello: 1. Yes, it is necessary to reball a PBGA after removal from the board. Once the part has been removed, the quantity of solder on the balls is out of control. This condition will not only result in an unacceptable variation in solder quantity

Please compare indium (In) / Tin (Sn) paste properties in terms of reflow profile, creep, grain structure, etc with other major no-lead solder formulations.

With the introduction of new lead-free alloys and higher temperatures to meet their specifications, can we expect different and/or more residues in the reflow soldering process?

Good morning Dr. Lee. I was wondering how flux chemistries have changed, or will change, with the transiton to Pb-Free, given the higher reflow temperatures required for SMT assembly?

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?

How are Component manufactuers addressing the PB free solder inititive? Since I am told higher processing Temps will be required to reflow the pb-free alloy.

Many machines for both reflow and wave are quite capable to run lead free but you are generally talking about the high end systems not the light weight units. Bob
