Considerations for Handmade weldability of SMD LED

Many factories were equipped without this wave soldering or mounting. using only the Handmade weldability of SMD LED. Working in this way, should pay attention to what?

1、The melting products but should be maintained as low as possible. Temperature of Welding Gun is 280° C-300° C lower than use Welding Gun as usual。solder wire with a melting temperature of about 220°.Suggested the Temperature of Welding Gun as far as possible low.

2、Notice the speed wants quickly ，weldability speed will rise about four times is best way. Welding Gun and solder wire blend should very tacit, must undertake the training of technicality, carry out very hard in the practice otherwise. That means, should send solder wire to Welding Gun right off, when Temperature of Welding Gun reaches 180°, Try to avoid extended periods of time at the SMD LED.
