I agree with Evtimov. What he didn't point out is that the surface tension of the solder would vastly overwhelm any force from air flow.

Can anybody suggest how can I achieve good solderability in convectional reflow oven If I reduced Convection Air Speed 80%. The whole purpose is to reduce 0402 LED tilting in the convectional reflow and the PCB having QFN with 60 to 120 sec soak, 30

I solder LEDs everyday from 0402 sizes on up. I work for an optical company so every product I make has LEDs. Some products have hundreds of LEDs per circuit. The problem is that clear materials are not filled materials and thus don't have the adv

I have seen the application with hot-bar soldering machines for SOT 23 LED packages. I could not find any of the machines in my search that specially state SOT 23 packages, but you might want to check with these guys: http://www.unitekequipment.com/

Does anyone have experience with automated Laser soldering equipment for SMT LED's? I have checked previous posts and did not find anything dealing with actual LED's. Most laser systems are set up for through hole and solder from the bottom of board.

The clear plastic packaging for LEDs is a LOT softer thermoplastic than the thermoset epoxies used on ordinary chips. I think people have had high failure rates when reflowing LEDs in all-plastic packages even at SnPb temperatures, and much worse at
