Abstract

The invention provides a test plate. The test plate includes a test mother plate and a test sub plate, wherein the test mother plate is printed with a first precision circuit, the test sub plate is printed with a second precision circuit, precision of the first precision circuit is lower than precision of the second precision circuit, technology precision of printing the first precision circuit onthe test mother board is lower than technology precision of printing the second precision circuit on the test sub plate, the test mother plate is connected with the test sub plate, and the first precision circuit is connected with the second precision circuit. Compared with the prior art, the test circuit is divided into a high precision circuit and a lower precision circuit, for the high precision circuit, the processing technology with relatively high processing precision is utilized for printing, for the lower precision circuit, the processing technology with relatively low processing precision is utilized for printing, and integral processing cost of the test plate is reduced.

Description

technical field [0001] The invention relates to the technical field of mass production testing, and more specifically, to a test board and a method for manufacturing the test board. Background technique [0002] Mass production testing of IC (Integrated Circuit, integrated circuit) products is a necessary procedure before IC products are applied to the market. Mass production testing of integrated circuit IC products requires the use of high-precision, high-reliability test boards. The specific test process includes, first adopting PCB (Printed Circuit Board, printed circuit board) process to process the test board, and the test circuit is printed on the finished test board, and then use the test circuit on the test board to test the integrated circuit IC product. Performance is tested. [0003] At present, in the process of manufacturing the test board, a high-precision processing technology is used for the entire test circuit, and the entire test circuit is printed on th...
