with solder paste and reflow process production. Therefore, LED lights to bring the volume of solder joints with smooth and not many joints cylindrical arc from the FPC pad at the extension to the LED electrodes. The LED lights with cottage version of the volume of solder joints is uneven, mostly a dot wrap welding foot, while there will be varying degrees of tin tip appeared, which is a typical phenomenon of manual welding.
