Abstract :
Laser resistor trimming, an effective tool for producing accurate and reliable electrical elements is discussed. Laser trimming has minimum effect on power handling capability; element value variation with time, temperature, and voltage; and electrical noise. The principles of laser trimming, laser types used, trimming techniques, and technology trends are described. Laser cutting of ceramics in such applications as electronic packaging and the use of lasers to pattern thin films are also discussed.<>
