About LS Laser Systems
LS Laser Systems GmbH was founded in 1993 and is a privately owned company based south of Munich (Hohenbrunn). The company develops, manufactures and distributes laser trimming systems for the adjustment of hybrid circuits, electronic components and sensors. In laser trimming, resistors are adjusted to a precise resistance value (passive trimming) or circuits are adjusted to defined functional values such as output voltage or frequency (active trimming) by material removal using laser pulses. The systems support thick-film and thin-film circuits on all common substrates, offer cut geometries such as P, D, L, U, J, meander, shave, window and grid, as well as measuring system integration for resistors, voltages, frequencies, inductances and capacitances. With more than 1000 systems installed worldwide, LS Laser Systems supplies some of the largest manufacturers of thick-film and thin-film circuits. Applications can be found, among others, in sensor technology, hybrid circuit and high-frequency engineering. In addition, the company offers an application center for feasibility studies and process optimization as well as after-sales services such as remote support, spare parts supply and system upgrades.
