Embodiment approach

[0038] For the support device 104, as an optional embodiment: it includes a connection device and a control device, the connection device is movably installed on the control device, the connection device can be a connecting rod, and one end of the connecting rod is fixedly connected to the probe card 103, The other end of the connecting rod is installed on the control device. The control device controls the movement of the connecting rod to control the movement of the probe card 103 , and the direction of movement can be up and down. It can be understood that the support device 104 can only control the movement of the probe card 103 in the vertical direction.

[0039] The above-mentioned control device and processor may be: an integrated circuit chip with signal processing capability. It can also be a general-purpose processor, including a central processing unit (Central Processing Unit, CPU), a network processor (Network Processor, NP), etc.; it can also be a digital signal...

Abstract

The invention provides a probe cleaning method and a laser resistance regulator, and relates to the laser field. The method applied to the laser resistance regulator comprises that whether dust attached to a probe which is mounted on the laser resistance regular satisfies a preset cleaning condition is determined; if YES, the probe is controlled to move to a preset cleaning position; and on the basis of the cleaning position, an output laser beam is controlled to scan the dust attached to the probe, so that the laser beam removes the attached dust. The method can be used to clean the probe more conveniently with better effect.

Description

technical field [0001] The present application relates to the field of lasers, in particular to a method for cleaning probes and a laser resistance adjustment machine. Background technique [0002] The laser trimming machine mainly uses a very fine laser beam to hit the thick and thin film resistors, and realizes the cutting of thick and thin film circuits through vaporization and evaporation of the resistors. The probe card has a plurality of probes welded to its main body, and each probe is connected to the measurement system of the resistance trimmer with lead wires. At least one pair of probes is required for the measurement of each resistance. During the process of vaporizing and evaporating the resistor with the laser beam, part of the resistor material will be sputtered out by high temperature melting (forming dust), part of it will be sucked away by the ventilation system, and part of it will stick to the probe tip. Over time, the dust particles on the tip of the ne...
