@Evtimov I can't use flux as the components being soldered can't cope with any contamination whatsoever. Even an ultra low solids no-clean flux will be too much. I also can't clean the boards after soldering due to any residual contamination from the

Jerry, just out of curiosity, why can't you use flux? Flux is essential part of soldering and it is there for multiple reasons. Flux we can also clean afterwords - even No Clean.

The change of squeegee pressure has a significant impact on printing. Too small pressure will make the solder paste unable to effectively reach the bottom of the stencil opening and not be well deposited on the pad. Too much pressure will cause tin The paste is printed too thin and can even damage the stencil.

Although reflow ovens may not have been dramatically changed during the last decade the reflow process changes step by step. With the introduction of lead-free soldering not only operation temperatures increased, but also the chemistry of the solder paste was modified to meet the higher thermal requirements. Miniaturization is a second factor that impacts the reflow process. The density on the assembly is increasing where solder paste deposit volumes decreases due to smaller pad and component dimensions. Pick and place machines can handle more components and to meet this high through put some SMD lines are equipped with dual lane conveyors, doubling solder paste consumption. With the introduction of pin in paste to solder through hole components contamination of the oven increased due to dripping of the paste.
