Laser precision laser welding <br> <br> HAZ is very narrow, small welding, in particular weldable material and a dissimilar metal of high melting point, and does not require additional material. Sewing and spot welding using solid $% & lasers abroad has been at a very high level. In addition, laser welding of the printed circuit lead-out line does not require the use of solder, and can reduce thermal shock, no impact on the circuit die, thus ensuring the quality of the integrated circuit die.

Domestic Situation <br> <br> After twenty years of effort, in terms of precision laser processing technology and equipment, even though China has been in the ceramic laser scribing and laser micro and small metal parts spot welding, seam welding and air tightness Welding and marking applications have been applied, but in the laser precision machining technology, the high-tech, high-tech microelectronic circuit template precision cutting and etching process, ceramic wafers and printed circuit boards of various sizes of through-holes The laser precision machining of blind holes and shaped holes and grooves is still in the research and development stage, and no corresponding industrial prototypes have been introduced. The majority of domestic users generally use imported templates or commissioned processing in Hong Kong and other places. Their high prices and long cycle have seriously affected the product development cycle. In recent years, a few foreign large companies have seen China's huge potential market in the laser precision processing industry. Has begun to set up branches in China. But high processing costs increase product costs and still discourage many companies.
