The interface pin plate 300 is mounted on the adapter panel 200 and has a first duct connector 310, a second duct connector 320, and multiple second pin holes 311. The adapter carrier plate 400 is mounted on the interface pin plate 300 and includes a first carrier plate 410 and a second carrier plate 420. The first carrier plate 410 is located above the first duct connector 310, and the second carrier plate 420 is located above the second duct connector 320. Both the first carrier plate 410 and the second carrier plate 420 have multiple probe slots 411. Based on the lower mold of the original test fixture of the ICT test machine, an ICT test adapter fixture is designed on the top. This ICT test adapter fixture then interfaces with the lower mold interfaces of other types of test fixtures. The interface board 110 is connected to the ICT test machine to form a signal conduction. The PCB board to be tested is placed on the first carrier board 410 and the second carrier board 420. The first air pipe connector 310 and the second air pipe connector 320 are opened to create a vacuum and attract the PCB board to be tested. The test fixture descends, causing the adapter carrier board 400 to press down. The probes of the ICT test machine pass through the first pin hole 111 and the second pin hole 311 to form a signal conduction between the interface pin plate 300 and the interface board 110. The probes pass through the interface pin plate 300 to contact the PCB board to be tested, thereby performing ICT testing on the PCB board to be tested. It should be noted that the number and position of the second pin holes 311 on the interface pin plate 300 are set according to the required adapter test fixture. By using this ICT test adapter, other types of test fixtures can be tested on the ICT test machine, realizing the compatibility of the ICT test machine with multiple test fixtures, improving compatibility and reducing testing costs.

The base plate 120 is provided with a first clearance opening 121, the size of which is adapted to the size of the interface plate 110. The perimeter 130 is installed around the base plate 120. The perimeter 130 installed around the perimeter enhances the overall stability of the fixture base frame 100 and forms a receiving space. The first clearance opening 121 on the base plate 120 is adapted to the size of the interface plate 110 so that the probe can pass through the first pinhole 111, and the interface pin plate 300 and the interface plate 110 form a signal conduction connection, which facilitates ICT testing.

[0034] Please refer to Figure 2 and Figure 3The base plate 120 is provided with an air outlet 122. The air outlet 122 on the base plate 120 enables gas circulation, keeps the internal environment of the tooling base frame 100 unobstructed and stable, and avoids problems such as excessive gas pressure caused by accumulation.

[0035] Please refer to Figure 2 and Figure 3 Handles 140 are installed on both sides of the tooling base frame 100. The handles on both sides of the tooling base frame 100 make operation more convenient, allowing the tooling base frame 100 to be moved easily, thereby improving efficiency and safety.

[0042] An ICT test adapter is designed based on the lower mold of the existing test fixture (e.g., the TS128 test fixture) of the ICT test equipment (e.g., the TS128 test equipment). This ICT test adapter then interfaces with the lower mold interfaces of other types of test fixtures (e.g., the TSO52 test fixture). By using this ICT test adapter, it is possible to test other types of test fixtures on the ICT test equipment, achieving compatibility of the ICT test equipment with multiple test fixtures, improving compatibility, and reducing testing costs.

Other types of test fixtures are placed on the ICT test adapter fixture, and then the PCB board to be tested is placed on the first carrier board 410 and the second carrier board 420. The first air pipe connector 310 and the second air pipe connector 320 are opened to create a vacuum and attract the PCB board to be tested. The test fixture descends, causing the adapter carrier board 400 to press down. The probes of the ICT test machine pass through the first pinhole 111 and the second pinhole 311, so that the interface pin plate 300 and the interface board 110 establish signal conduction. The probes pass through the interface pin plate 300 to contact the PCB board to be tested, thereby performing ICT testing on the PCB board.
