DEVICE FOR ADJUSTMENT OF THICK-FILM RESISTORS Russian patent published in 2020 - IPC H01C17/00 

FIELD: technological processes.

SUBSTANCE: device for adjusting thick-film resistors relates to microminiaturization and radioelectronic equipment and can be used for production of high-precision and precision film resistors. Device for adjusting thick-film resistors comprises a reference voltage source (1), comparator (2), resistance meter (3), a sign analysis unit (4), unit for selecting module (5), controlled reference voltage source (6), analogue-to-digital converter (ADC) (7), multivibrator (8), shift register (9), first group of elements AND (10-1…10-n), data storage unit (11), second group of AND elements (12-1…12-n), digital-to-analogue converter (DAC) (13), flare discharge generator (14), working electrode (15), adjustable resistor (16), substrate holder (17), OR element (18).

EFFECT: technical result is broader functional capabilities and high percentage yield of film resistors.
