Abstract

The method includes wire carrier, needle dial, linear probes, buffer element of needle dial, buffer element of probes, guard plate, and linear bearing set etc. main elements. Being combined through linear bearing set, the needle dial and the wire carrier are spaced by the buffer element of needle dial. The needle dial consists of carrier plate, multiple blocks of guiding plate, and multiple plates for movement of needle. Each linear probe in vertical or tilting position is inserted to plug seat prearranged on the carrier plate, each guiding plate, and plate for movement of needle. Head end of linear probe is corresponding to point to be tested of object to be tested, and tail end of linear probe is inserted to the support part of buffer element of probe. Being in prearranged thickness, the guard plate is setup between the wire carrier and the needle dial in order to make test reach purposes of stable and accurate test.

Description

technical field

[0001] The present invention relates to a test method for a mounted board, in particular to a test method for a mounted board that can provide more accurate, stable and reliable detection operations for a mounted board that has completed the installation of electrical components and has tiny measuring points method. Background technique

[0002] The existing conventional equipment used to test the circuit boards that have completed the installation of electrical components (commonly known as ICT testing, or In Circuit Test) is roughly as follows: figure 1 As shown, it is mainly provided with a floating plate 10 for the bearing of the mounting board 1, on which a receiving groove 101 is provided at the corresponding position of the electrical component 11 of the mounting board 1, and a receiving groove 101 is provided at the corresponding position of the point 12 to be measured. There are through-holes 102; the cable tray 20 is composed of at least one splint...
