PCB test method and device

Abstract

The invention discloses a PCB test method and device, and relates to the technical field of metal-based printed circuit board manufacturing. The PCB test method is applied to equipment in which n flying probe test machines are connected in series, a test network is divided through a test host, a total test network is divided into m*n test subareas, the number of the test subareas corresponds to the number of total test axes, and each test axis is responsible for one test subarea; and when testing is carried out, along with advancing of a PCB, the testing axes of the flying probe test machinescorrespondingly carry out detection in different testing subareas, and when all the flying probe testing machines are passed, all the testing subareas are also tested so that testing of the PCB to betested is completed, and a whole test method is efficient and capable of carrying out continuous and automatic testing.

Description

technical field [0001] The invention relates to the technical field of manufacturing metal-based printed circuit boards, in particular to a PCB testing method and device. Background technique [0002] With the development of the electronics industry, customers are increasingly pursuing the heat dissipation of PCB products. Metal-based thick copper plates are more and more used in high-power lighting and power supply products due to their high-efficiency heat dissipation performance. As an electronic product, the detection of its electrical performance is essential. The traditional method is to open a test stand for high voltage and on-off testing. This test method is suitable for batch testing, but it needs to make a large number of test stands, which is costly and requires a lot of space. Storage of test racks requires innovative design of a method that does not require test racks and meets continuous automatic testing. [0003] The traditional PCB test method must use a t...

Problems solved by technology

[0003] The traditional PCB test method must use a test frame for testing. The production of the test frame requires a production cycle and requires a lot of production costs. In addition, due to the relatively large size of the test frame (one model requires 1 to 2 test frames), it needs to occupy A large amount of storage space, and it takes a lot of personnel to manage. The information of the test process needs to be recorded manually, which is easy to miss or make mistakes. The entire test cost and management are more troublesome.
