Electronics
From welding batteries and disk drive flexures to precision cutting electronic stencils.
Batteries are made at a very high rate, sometimes over ten per second. Pulsed Nd:YAG lasers can optically match the speed of the moving cell, spot welding without contact, electrode wear or sticking.
Lasers provide one of the most reliable methods of direct part marking and easily achieve the high contrast details required to easily trace almost any product.
Disk drive flexures must be accurately assembled from three or four pieces of stainless steel ranging from 20μm to 150μm thickness. Lasers are the only joining solution for this application.
Lasers easily produce the seam and and spot welds required to assemble and hermetically seal sensitive devices such as microwave packages, sensors and relays.
The successful manufacture of electronic printed circuit boards rely on precise dispensing of solder paste via a metal stencil. JK Fiber Lasers are used on dedicated machines to micro cut individual stencil apertures at high speeds.
Laser spot welding has helped make the telecoms and internet revolution possible. A key application is pig tailing, where a length of output fiber is aligned over the transmitting laser and spot welded into position.
