TWI280375B - Retaining device for testing operations of motherboard and testing system having the same - Google Patents

Abstract

A retaining device for testing operations of motherboard and testing system having the same, applied and disposed in the testing case and having plural retaining posts that are spaced mutually and extend upwards through the testing case from the bottom respectively, a first support panel and a motherboard. The retention of the motherboard is subjected to a facing surface support constituted by the first support panel and the retaining posts instead of a single-point support, ensuring that bending of the motherboard due to uneven distribution of the weight is prevented so as to reduce the probability of causing short-circuits or circuit breaks to the internal circuit in the motherboard.

Description

1280375 IX. Description of the Invention: [Technical Field] The present invention relates to a test system, and more particularly to a fixture for a test of a main board and a test system having the same. [Prior Art] The motherboard is a highly sophisticated product. Each motherboard needs to pass strict and detailed tests before leaving the factory. After confirming that all the measured values meet the set standards, they can be officially sold. Referring to FIG. 1 , the device phase currently used for measuring the motherboard i is composed of only one test platform 21 ′ and four positioning posts 22 respectively fixed on the test platform 21 (due to the plane angle, FIG. Only two positions can be seen in the middle. Each of the four corners of each motherboard has a perforation u' so that the four perforations u of the main board i can be positioned relative to the dislocation column 22 22 is inserted into the top end, and a nut 23 is twisted on the top surface of each positioning post 22, and the screwing between the nut 23 and the positioning post 22 causes a pressing positioning effect on the main board 1. After the motherboard 1 is electrically connected to other electronic devices (not shown), it can measure whether the motherboard i has a normal execution function. The conventional device is supported by the four corners of the motherboard i. The main device is limited to the home board 1 and the other motherboards are equipped with other electronic devices! The weight does not appear to be evenly distributed, and the center of gravity is often: = the location of the added electronic device, but the lack of the positioning post 22, the I 'the motherboard 1 is quite easy to occur as shown by the imaginary line, to report It may cause the internal line signal of the motherboard 1 to be short-circuited.
