Abstract
The press-in terminal is a special-shaped cross-section suitable for press-in connection. According to the different design of the press-in connection, the press-in connection is divided into two processes: solid press-in connection and flexible press-in connection. This paper mainly analyzes the requirements of the PCBA flexible solderless press-in connection process introduced in the DCS safety equipment of nuclear power plants, identifies the key control requirements. The test items are determined by the design of the application scheme, and various forms of tests are conducted. The data of test is obtained. Based on the test results analyzed, the reliability of the flexible press-in connection process implementation is verified, which laid the foundation for the application of the later flexible press-in connection process, and can also form a set of evaluation methods for the flexible press-in connection process.
