Chrissie, I'm glad you (and your people) made it through the painful process of reworking all those BGA's. Hope all your boards sucessfully pass test. Now on to the larger issue. In my experience, the solder paste screen printing process is (along

Anyone using selective soldering pallets to run boards with previously reflowed bottom side SMT through the wave? Any comments, pro or con? Seems like a reasonable approach for someone that doesn't want to install a dispenser.

For whatever its worth, IPC does not require a full fillet in this situation. If it has to be a complete fillet due to contractual agreements you may want to try and preheat the board first with hot air or something and then solder. Russ

What happens when the solder preform drys out? What happens if we are to saturate the preforms the night before a build. A no no or what? Sean

If you are beginning a new evaluation of fluxes, make sure you consider an ultrasonic spray fluxing system with recipricating head. A fluxer from Ultrasonic Systems can add valuable data to your wave solder process

Here is a thread from the fine SMTnet Archives from a couple of weeks ago, where we spoke about the topic of mixed lead-free solder with components that have lead-bearing solderability protection: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Messag

A bit of a long shot but ... Does any know if Reddish Electronics � SM1500CXE oven is suitable for lead-free soldering ? i.e Can it handle the elevated temperatures ? TIA Steve

Sounds like your flux to me. Since you cannot change the board or the machine, changing flux would be one question mark you could take away with a phone call and a sample. You will really be surprised how different fluxes can affect your final prod
