Scheme realization

transformation process

HIOKI IN-CIRCUIT HiTESTER 1220 system has a history of more than ten years. The software runs in MS-DOS environment and does not provide much flexibility or function. For example, the system does not support 3rd software integration and interfaces based on Microsoft Windows windows, which are more user-friendly.

Modern test systems need to be flexible so that users can deploy in different environments and requirements. It needs to be compatible in order to extend the system functions with external third-party hardware. It needs to be fast, accurate and efficient.

Hardware conversion

Fixture sharing

The PTI816S is designed with full consideration of compatibility. By optimizing the fixture interface and signal transmission, it can be directly compatible with the testing fixture of HIOKI 1220. We have carried out a comprehensive inspection and adaptation of the fixture to ensure that it can be tested stably and accurately when used on PTI816S, thus avoiding the test error and equipment failure caused by the incompatibility of the fixture.

Cable conversion

In view of the inconsistent transmission of some signals, we specially designed and made the conversion cable. These conversion cables can accurately convert the signal on the HIOKI1220 fixture into a signal that can be recognized by PTI816S. Both HIOKI 1220 and PTI816S adopt 64PIN cables, which ensures the integrity and stability of the test signal and the solid and reliable physical connection between the fixture and the new equipment.

Program conversion

In order to realize the rapid conversion from HIOKI 1220 test program to PTI816S, we developed a special program conversion tool. This tool can read the program files of HIOKI 1220, and automatically transform and optimize the test steps, parameter settings, signal definitions and other contents in the original program according to the programming specifications and grammar requirements of PTI816S, and generate a test program suitable for PTI816S.

According to the performance characteristics of PTI816S, some test parameters and algorithms in the program are optimized to further improve the test speed and efficiency and ensure the reliability and consistency of test results.

Comparison between PTI-816S and HIOKI 1220：

1. Test speed：PTI816S adopts advanced test algorithm and high-speed processor, and the test speed has been significantly improved compared with HIOKI 1220. When testing the same product, the testing time of PTI816S is shortened by about 20%, which greatly improves the production efficiency and meets the increasing order demand of customers.
2. MES function：PTI816S has perfect MES interface function, which can seamlessly connect with customers’ existing MES system. In the process of testing, the test data is uploaded to MES system in real time, including product model, batch, test results, test time and other detailed information, which provides strong support for the information management of production process. HIOKI 1220 doesn’t have this function, so it can’t meet the customer’s requirements for traceability of production process.
3. Key test function：PTI816S is equipped with a professional key testing module, which can accurately test the parameters such as the pressing force, rebound time and combo times of product keys, effectively detect the bad conditions of keys, and ensure the quality and reliability of product keys. HIOKI 1220 needs to add complex test tools to achieve similar key test functions, and the test accuracy and efficiency are far less than PTI816S.
4. Bar code scanning function：PPTI816S integrates high-performance barcode scanner, which can quickly and accurately read all kinds of bar code information, and automatically store the bar code data and test results in the test process, which is convenient for subsequent product traceability and management. HIOKI 1220 has no built-in bar code scanning function, which can’t meet the customer’s demand for automatic product identification and management.
5. Data burning function：PTI816S supports the Inline data burning function, and can quickly and accurately burn the data of the product’s memory chip according to the preset program and data during the test process, which greatly improves the production efficiency and product consistency. If HIOKI 1220 needs to realize the data burning function, it needs to connect a special burning device, which is complicated and inefficient to operate.

By replacing HIOKI 1220 with PTI816S, customers have successfully solved the problems such as equipment aging, difficult maintenance and upgrading, and at the same time realized the expansion of testing functions and greatly improved the testing speed, effectively improved the production efficiency and product quality, and provided strong support and guarantee for customers’ production development.
