Liyuan Haina in Shanghai International Electronic Circuit Exhibition CPCA, it is one of the most authoritative electronic circuit exhibitions in China.

The main products at this exhibition are PCB electroplating rectifiers. The market share of positive and negative pulse power rectifier in the PCB industry is up to more than 70%, especially the unique pulsed power patented technology, which has set a number of leading domestic products, solving the problems of uneven plating and poor electrical conductivity of traditional PCB electroplating rectifier, which is the first choice for 5G PCB board process.
