Description

Technical Field

[0001] The utility model belongs to the technical field of electronic product manufacturing, and specifically relates to a general-purpose pin carrier board. Background Art

[0002] As an indispensable device in the electronic production process, the in-circuit emulator is widely used in the program writing and function testing of chips. The traditional structure of the pin carrier board often has problems such as poor compatibility, complex maintenance, and low test accuracy. Especially when dealing with chips of different packages and sizes, it is often necessary to replace the entire pin carrier board, increasing production costs and downtime. In addition, due to the unreasonable fixing method between the pin board and the carrier board, the tip of the needle is prone to shift during the test, affecting the accuracy of the test results.

[0003] If the bayonet design between the pin board and the carrier board is not firm enough, after long-term use and frequent plugging and unplugging operations, loosening is likely to occur, which will not only affect the connection effect between the pin board and the carrier board, resulting in unstable transmission of test signals, but may also cause mechanical failures, affecting the normal use of the in-circuit emulator, and will also cause the tip of the needle to shift during the test. The shift will directly affect the stability and accuracy of the test signal, and then affect the results of chip programming and testing. Since the pin board needs to be adapted to a variety of connectors, if the adapter head is not effectively reinforced during the connection process, it is very likely to fall off or be damaged due to uneven stress during the test, thus affecting the smooth progress of the entire test process.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model
