Fixing Jig {JIG FOR FIXING PRODUCT}

The present invention relates to a product fixing jig, and more particularly, to a product fixing jig capable of stably fixing a product during operations such as press-fitting, welding, laser trimming and the like.

The sensor is equipped with a resistance plate so that the voltage can be measured using a resistance. The resistive plate performs laser trimming to adjust the resistance value.

The laser trimming is a step of obtaining a desired resistance value and at the same time suppressing a deviation. For example, since the current path of the resistance plate is narrowed by laser trimming, the resistance value rises.

Since the resistive plate performs the formation of several hundreds of resistors on the alumina substrate at one time, a slight deviation occurs in the printing state, and when a chip is made with the resistance value deviation generated, only a desired resistance value can be obtained only to some extent. Laser trimming is performed.

However, since equipment that can adjust the laser trimming position in laser trimming is expensive, it is difficult to invest in expensive equipment in the initial product development stage, not in the mass production stage. In addition, since the trimming low-cost equipment with a fixed laser position is used in the product development stage, it is necessary to newly manufacture a jig for fixing the resistance plate (product) whenever the product design is changed (resistance plate size, There is.
