LED BOARD P0.8, Super Retina Display
With the progress of science and technology, customers' requirements for outdoor display screen are also increasing. We have received an order from a well-known photoelectric enterprise in Switzerland. They required the distance between two pad is 0.1mm, and the pad size is 0.1*0.1mm. What ? s more, they required that the solder mask bridges between pads should be kept intact and the PAD density should be 87.6%.
PCB production process
Our technical department started from the processing parameters of the machine, time control and manual modulation of soldering ink, etc. At present, we have successfully overcome this technical difficulty. The defective rate of mass production of 50,000 PCS has been controlled within 0.3%.
