2. Laser trimming - Wikipedia

   en.wikipedia.org/wiki/Laser_trimming

   Laser trimming is the manufacturing process of using a laser to adjust the operating parameters of an electronic circuit. Laser-trimmed precision thin-film resistor network from Fluke, used in the Keithley DMM7510 multimeter. Ceramic backed with glass hermetic seal cover. Laser trim marks are visible in the grey resistive material.

3. Thick-film technology - Wikipedia

   en.wikipedia.org/wiki/Thick-film_technology

   With laser trimming two modes are used; either passive trimming, where each resistor is trimmed to a specific value and tolerance, or active trimming, where the feedback is used to adjust to a specific voltage, frequency or response by laser trimming the resistors on the circuit while powered up.

4. List of resistors - Wikipedia

   en.wikipedia.org/wiki/List_of_resistors

   The resistance of both thin and thick film resistors after manufacture is not highly accurate; they are usually trimmed to an accurate value by abrasive or laser trimming. Thin film resistors are usually specified with tolerances of 1% and 5%, and with temperature coefficients of 5 to 50 ppm/K.

   A: preset resistor, B: preset resistor (alternate), C: preset potentiometer, D preset potentiometer (alternate), E: preset inductor, F: preset capacitor In circuit diagrams, the symbol for a variable component is the symbol for a fixed component with a diagonal line through it terminating in an arrow head.

6. Molecular-beam epitaxy - Wikipedia

   en.wikipedia.org/wiki/Molecular-beam_epitaxy

   Molecular-beam epitaxy (MBE) is an epitaxy method for thin-film deposition of single crystals. MBE is widely used in the manufacture of semiconductor devices , including transistors . [ 1 ] MBE is used to make diodes and MOSFETs (MOS field-effect transistors ) at microwave frequencies, and to manufacture the lasers used to read optical discs ...

7. Selective laser sintering - Wikipedia

   en.wikipedia.org/wiki/Selective_laser_sintering

   An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
