Laser Resistor Trimming System

Turnkey solutions for circuit component production.

Laser resistor trimming system.

Als series lasers from aurel can be used for various front and back end applications on ceramic glass silicon plastic and pcb substrates. Involves removal of material from a resistor to increase its resistance. We offer anything from ohmic trimming of chip resistor networks to active and functional trimming of hybrids digital and rf circuits. Contact us for sales.

With 30 plus years experience in the co2 yag laser micro machining laser resistor trim marking and diamond saw dicing business questech services plays a major role in shipping production prototype and r d quantities of commercial consumer and military parts worldwide. The precision equipment delivers a trim accuracy as high as 0 1 a measuring accuracy of 100 ppm and a range between 0 1 ohm to 1 gigohm. The second is the oxidization of the resistor material in the presence of silicon dioxide. We live our world class iso quality system.

The first is simply the material evaporation by the high power laser beam. Advanced laser resistor trimming system. Additionally the jenlas comes with back reflection protection an on axis guide laser and both software and hardware control interfacing making the system easy to integrate into modern industrial process systems. This makes this laser ideally suited for high speed resistor trimming applications.

Laser trimmed precision thin film resistor network from fluke used in the keithley dmm7510 multimeter. The system uses four independent flying probes eliminating restrictions on component location size orientation and layout. Rapitrim laser resistor trimming systems provide solutions for both quick turn and volume production thick film and thin film resistor trim. Laserod s systems division builds and integrates a full line of diode and fiber laser micromachining equipment for uses that include silicon wafer resizing resistor trimming cutting thin metals and plastics scribing substrates of alumina and silicon resistor trimming and patterning thin films such as ito on glass or plastic.

Complete rebuilt thick film thin film laser resistor trimming systems. The standard rapitrim trim and test system accepts substrates up to full size pcb panels. Three mechanisms can be involved when laser trimming. Legacy and used laser trimming system parts repair.

Large format for full size pcb panels. A schematic of a typical laser trimming system is shown in figure 2. Examples include tantalum nitride and polysilicon. With turn key systems for passive and active trim high speed flying probe technology that eliminates the inherent limitations.

Laser trimming is the manufacturing process of using a laser to adjust the operating parameters of an electronic circuit. 16 x 12 large microwave circuit board is trimmed by yag laser. Laser resistor trimming systems.
