The load detection device and the load method of detection null electronic parts of the bonding

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for detecting a load of a crimping contact head for electronic parts capable of improving the accuracy of controlling of the load in the crimping.;SOLUTION: In a crimping contact device of an electronic part for bonding an electronic part to a substrate 3 by the crimping contact head 17 by virtue of the pressure, a load cell 15 and a spring 16 having a linear load-displacement characteristic as a load detecting means for detecting the load applied to the crimping contact head 17 are interposed between a lifting section 7 for movably supporting the crimping contact head 15 in the vertical direction and the crimping contact head 17, are used in a series combination. As a result, a displacement among of the load detecting means is increased and the variation amount of the pressure load by each lifting/lowering operation is reduced so that the resolution of the pressure load can be improved, and then the accuracy in controlling of the pressure load can be improved.;COPYRIGHT: (C)2003,JPO
