New Description: [New Technology Field] This creation is about a density conversion mechanism for PCB testers, especially for a printed circuit board (PCB). This device is a PCB test. Machine density conversion mechanism. - [Prior Art] In the past, the PCB test industry had a standard universal test point specification. The test point specification was called φ four density (that is, 400 test contacts were evenly arranged in 1 square inch), and each test was performed. The point must be connected to the test circuit, and the existing PCB test machine solders the test circuit pins directly to the test contacts for testing. However, today's PCB board testing machines usually have the following problems: Nowadays, the integration of circuit boards is getting higher and higher, the solder joints are getting smaller and smaller, and the density is denser, and the technical development of the PCB board is reported. Speed, Enterprise # can not be mixed, even leading to the failure of enterprises in the fiercely competitive market.
