Wafer Resizing and Coring in San Jose

For System Integration and Shop Service: Laser Resistor Trimming of Thick- and Thin-Film Hybrid Microelectronic Devices ACTIVE AND PASSIVE Large board thick film resistor trimming is a specialty of Laserod. Board sizes to 24″ x 24″ or 36″ x 24″ are easily handled. Upon job completion, Laserod will provide you with Excel graphs that indicate your initial and final trim values for your comparison. Laser Trimming Hybrid Microwave Boards Fig. 1. 16″ x 12″ large microwave circuit board is trimmed by YAG laser.. 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. PASSIVE TRIMMING Involves removal of material from a resistor to increase its resistance. The resistance or voltage parameter is monitored across the component contacts. ACTIVE TRIMMING Involves removal of material from a resistor to change a circuit parameter. Also called functional trimming, because the circuit is functionin...

MICROMACHINING AND PATTERNING Laserod specializes in laser machining of silicon (Si). We offer precision laser cutting, scribing,  coring (resizing) , flat or notch cutting,  microdrilling holes , singulation and dicing of silicon and MEMS devices. Typically applications of laser machining silicon include the manufacture of  MEMS  devices, sensors, detectors, and solar cells. Silicon is brittle, has a crystalline structure, and has a high vaporization temperature, none of which present a problem to laser machining. For example crystalline direction is of no hindrance to the laser. Also lasers can cut in circles and produce flats or notches all in one operation. Lasers cut circles of almost any size so coring (resizing), and via hole drilling are easily done using pure laser energy with no mechanical contact.

Laserod is proud to be in the forefront of laser patterning, also referred to as etching, for displays such as a touch screens. Other terms for this process are laser structuring and laser scribing. This patterning process removes the invisible and conductive material coating on the display to leave behind a functional circuit, or pattern, on the display.  The remaining conductive pattern guides the electrical signals go where they are intended. The etched/scribed circuit patterns are applied to a thin coating of Transparent Conductive Oxide (TCO) on a substrate of glass or plastic film. Examples of TCO are Indium Tin Oxide (ITO), carbon nanotubes, and thin gold coatings. TCO coated glass and plastic are typically used in flat panels, windshields, architectural windows, photovoltaics, and touch screen displays. They are cut by us down to 10 micron laser cut width. For large area removal we simply overlap the ablated 10um spots at high laser repetition rates...

The following is based on a paper by Rodney Waters, originally published in  LIA Handbook of Laser Materials Processing , Laser Institute of America, Magnolia Publishing, Inc., Orlando FL,  2001 , p.637. It was a distinct honor to have been invited to contribute the section on Laser Patterning. We offer this as proof of our pioneer world leader status in laser patterning, etching, and structuring of transparent conductive coatings on flat panel displays. Examples of coatings include Indium Tin Oxide (ITO), carbon nanotube (CNT), silver nanowire (AgNW), chrome, gold and all others without exception. PRINCIPLES OF LASER PATTERNING BY SOLID STATE LASERS Direct write maskless pattern generation Dry process laser patterning and etching, single step Up to 1.6m scan area and up to 5m/sec writing rate Typical scan area is 450mm. Typical writing rate is under 1m/sec (depends on pattern geometry). Visit us here at  https://laserod.com/applications/patterning-displ...
