The lead frame structures of LET(light emitting triode)are much fine and with high yields, it is for high speed punch with very high precision and life.

I also adjusted the levels of the base rendering architecture to darken the exterior and punch up the light in the interior.

Moulds of each process is designed in light of the process optimized, and introducing the mould structure of the forming mould and side punch mould for trimming, and the design of key pieces.
