Zhisheng said that the use of advanced dry etching process equipment (gaseous plasma reaction) will not produce pollution caused by liquid process. The etching precision is the same as that of the world's largest manufacturers, which can brighten LEDs by 30%. The yield has reached 85% to 95%.
PCB factory Zhisheng last year, LED equipment accounted for a small proportion of revenue, this year's PSS solution is LED strong hit orders, but from the current economic situation, it is still the highest visibility of HDI orders for PCB, can be extended to In the second quarter, the panel order was flat.
PCB factory Zhisheng self-contained Taiwan's parent company's pre-tax surplus was 476 million yuan, down 2.18% from the previous year's 487 million yuan, and the pre-tax earnings per share was 3.05 yuan. 
PCB dry equipment manufacturer Zhisheng actively strives for the LED market. The company expects to exhibit PSS TurnkeySolution, which not only reduces pollution, but also increases LED brightness by 30%. On LED related equipment, it will be able to share some business opportunities. Zhisheng pointed out that a 4-inch PSS solution will be launched in 2012.
