Detailed description of the invention
It is described below for disclosing the present invention so that those skilled in the art are capable of the present invention. Preferred embodiment in being described below is only used as citing, it may occur to persons skilled in the art that other apparent modification. The ultimate principle of the present invention defined in the following description can apply to other embodiments, deformation program, improvement project, equivalent and the other technologies scheme without departing from the spirit and scope of the present invention.
Present situation as described in background, in camera module industry, the requirement for pixel is more and more higher, test accuracy for various workpiece requires also more and more higher, a lot of existing measurement jigs can not meet the requirement for test accuracy, one of them underlying problem is exactly fixing for test piece in test process, also as indicated in the background, existing settling mode, although providing certain solution for this problem, but as described in analyze, well do not solve underlying problem, so needing common measurement jig it is further proposed that preferably improve or innovative solutions, disclose the present invention fully below for the solution process of problem and present disclosure.
Existing common test jig structure is mainly offer one tabular plane measurement jig 100, as shown in Figure 1, when carrying out COF test, one COF workpiece 1 (flexible circuit board) is positioned on a surface 101 of described measurement jig 100, if in test process, described COF workpiece 1 is subject to external directed force F, owing to there is no obvious barrier force in the horizontal direction, and described measurement jig 100 is generally metal material makes, friction factor is less, therefore the frictional force between described COF workpiece 1 and tool contact surface is less, so being easy to relative movement, and this movement will cause the error of test, the accuracy that impact is measured. from here it will be seen that cause the relative movement that a reason of measurement error is just horizontally oriented.
Such as Fig. 2, illustrated in Figure 3, it is the design process that prevents measured deviation tool of according to a preferred embodiment of the invention. In order to solve the relative movement problem of horizontal direction set forth above, existing common survey tool is improved, a jig body 10 is first provided, be used for placing described COF workpiece 1. Go out to send consideration from mechanics principle, reduce the relative movement between contact object, can several aspects consider: one is increase the frictional force between contact object, and mainly have two kinds for increasing friction force method between two objects determining, first method is to increase normal pressure, the impressed pressure being namely subject at the object of two contacts, the impressed pressure that namely described COF workpiece 1 and measurement jig 10 are subject to, described COF workpiece 1 applies pressure fixing, second method, increases the friction factor of two objects; Another is directly to apply barrier force in relative motion trend direction.
