Qinshang Optoelectronics will not enter the LED upstream in the next few years
Li Xuliang said that LED is a brand new industry, including the upper, middle and lower reaches. It is not easy for a company to do all the links. It will not enter the upstream in the next few years. For example, the chip, now LED upstream, there are hundreds of companies, in the situation of oversupply, the company to do the application side, the brand is good, more beneficial to the company.
Do you know what is ENEPIG in PCB?
What is ENEPIG?ENEPIG-Electroless Nickel Electroless Palladium Immersion Gold is a surface finish for Printed Circuit Boards.ENEPIG works well with lead free and conventional eutectic solder alloys.This is the best way for gold wire bonding. Advantages for ENEPIG:
1.[Black Nickel" free – no possibility of grain boundary corrosion of nickel surface by immersion gold
2.Palladium acts as an additional barrier layer to further reduce copper diffusion to surface, thus ensuring good solderability
3.Palladium completely dissolves into solder, without leaving an excessively high P% rich interface, exposing an oxide-free nickel surface allowing reliable formation of Ni/Sn intermetallic
5.Withstands multiple lead-free reflow soldering cycles
6.Demonstrates excellent gold wire bondability
7.Process costs substantially lower than electrolytic nickel gold or electroless nickel electroless gold
