Description
technical field [0001] The invention relates to the technical field of pads, in particular to an FPC pad design structure of a dual crystal LED. Background technique [0002] In flow soldering, most of the solder at the soldering point climbs along the lead, and the solder between the lead to be soldered and the pad is insufficient or has no solder. It is also called core pulling phenomenon, which is one of the common welding defects. It is more common in vapor phase reflow soldering. Serious virtual soldering phenomenon formed between the pin and the chip body. [0003] In the existing technology, conventional LEDs generally only have the phenomenon of soldering at the bottom, while dual-crystal LEDs are LEDs with special structures. When welding dual-crystal LEDs, soldering is mainly caused by side and rear soldering. The welding quality of crystal LED affects the use effect. Therefore, we propose a FPC pad design structure of dual crystal LED to solve the above problems...
