If you allow 3 seconds for insertion of each connector and 2-3 seconds for each solder joint, then add a 10-12% contingency allowance you shouldn't be far out. Maybe get an averagely rated operator to build one on the clock. Regards, Chris

What will be the effect on the above with regards, to solderability, solder joint strength, electrical characteristics etc. thanks and best regards in advance.

We are currently experimenting on an 18 layer 2 oz. copper backplane. The spec is calling for 100% solder joint top to bottom. Any input greatly appreciated.

Since you have used malcom softener, did you encounter and sudden rise of void level in the solder joints as compared to manual stirring?

1. Which manufacturers have proven the immersion silver is reliable after solder joint assembly? 2. Who has published guidelines for storing and handling immersion silver boards? 3. Is the immersion silver finish wire bondable? epoxy bondable? or j

What are the specifications on the solder that you use? IE: Water soluble,RA,RMA, N/C? Also do you clean the boards and if so how and what detergent if any are you using?

We use water soluble paste, Kester R560. These units are wave soldered and cleaned in an Electrovert Aquastorm water wash with a 3% Kester saponifier solution in the first stage.

We do perform multiple reflow only for reliability testing. 90% of the time we have not seen any change in the solder joint and no change in electricals. If you do see failure you might want to see the solderability of the surface finish too.. jus

A bad solder joint, usually caused by a lack of knowledge & experience, possibly stemming from getting everyone else to do your home work!
