This article describes the field of application of the linear motor and its practical prospects.A specific analysis of linear motor control principle is shown.A fast method to measure motor force constant is focused on.And the feasibility and validity of the method is verified by experiments.

This article introduces the definition of Machine Vision,mainly research Template matching algorithm,and apply it to semiconductor equipment.This paper verifies and analysis the Template matching algorithm of shape-based and Gray Value-Based.The fit condition of use and characters are got by many experiments.

Abstract：The workpiece should be heated when the wire bonding machine is working, and it is heated by the heat table,It needs to heated symmetrically.Otherwise the product qualty is affected..in this article we simulate the work state of the heat table with the software of ansys fist,then we set lot of experients,and we find the factors which affect the equal tenmpreture of the heat table at last.
