RESISTANCE ADJUSTMENT METHOD FOR RESISTOR, AND SYSTEM

WIPO Patent Application WO/2021/004338

A1

The present disclosure provides a resistor fixture and a resistance adjustment machine, pertaining to the technical field of laser trimming. The invention alleviates the technical problem in which when laser is used to perform trimming, a detection assembly is unable to detect a resistance value of a resistor under test due to a limited assembly space. The resistor fixture comprises a frame, a detection assembly disposed within the frame, and a drive assembly capable of driving the detection assembly to approach or move away from a resistor under test. A trimming structural member, configured to trim the resistor under test, and the detection assembly are located on two opposite sides of the resistor under test. The present disclosure is suitable for laser resistor trimming. When a laser head is used to trim a resistor, the laser head is close to the resistor, and a conventional arrangement in which a detection assembly and a trimming structural member are disposed on the same side of a resistor under test would hinder accurate measurement of the resistance value of the resistor under test. The present disclosure has a configuration in which the trimming structural member configured to trim the resistor under test and the detection assembly are located at two opposite sides of the resistor under test, thereby enabling accurate measurement of a resistance value.
