Technical Field

[0002] In the semiconductor industry, push-pull force testing equipment is an indispensable device. This equipment mainly uses mechanical sensors to detect the chip shear strength, the shear strength of the solder balls, and the reliability test of the small force value of the solder wire. It can also be used for the vertical separation test of BGA chips and PCB boards, and for the pull test of some electronic components. The pull test of the chip on the PCB board is a high-force pull test with a maximum pull of more than 100KG. The tension sensor must be calibrated with weights to better ensure accuracy. Currently, many high-force calibrations on the market are achieved through third-party sensors rather than actual loading weight calibration.
