Lead free is not define as NO lead and "a maximum concentration value of 0.1% by weight in homogeneous materials for lead shall be tolerated." Check below link. So replaced your solder from the pot when exceed 0.1%. http://www.leadfree.org/files

Can anyone give me any information on the longivity of titanium insert wave pallets. What I am looking for is the integrity of thin walls over several hundred cycles and the interface between the insert and the durostone material.

I am considering moving my spray fluxer into a completely separate operation. Has anybody any comments of sraying VOC free flux on boards, then putting them in a drier/holding rack for possibly say overnight, then running them through wave solder?

Dave, thanx for your input. Its really helps. Just need some clarifications on : 1) Consider evaluating chimney versus programmable / conveyored machines separately. Question: is there any disadvantages of the programmble/conveyored vs chimney ?

Have you considered point-to-point selective soldering using microflame ? If we look at the excellent points that Dave made.... The clearance required for the microflame is minimal, no tooling plate is required - only to fixture the parts and the p

Selective soldering machines are a good way to "finish automation", if the design of the PCB is conducive to the application with just a few components to solder. Your points are good. A decision matrix for selecting a machine might also include:

Are you spray fluxing ? If so, check that you are getting flux onto the whole pcb uniformly.... That BLT flux is a water based material, are you getting rid of all the water in the preheat before you get to the wave ( can you hear any spitting as t
