ICT & FCT INLINE testing

Project Case

Lamp control panel Automatic test line

As the world’s leading provider of automotive electronic solutions, customer B has always been deeply involved in the research and development and manufacturing of high-end automotive lighting systems. Facing the explosive demand of the new energy vehicle market, its traditional off-line manual testing mode encounters three challenges: the rising labor cost restricts the profit space, the lack of productivity flexibility limits the delivery capacity, and the risk of quality control consistency caused by manual detection fluctuations.

In order to break through the bottleneck of development, customer B took the lead in initiating intelligent transformation, and joined hands with PTI to build a whole-process automatic test system, realizing the digital closed loop of ICT circuit test, IC program burning and FCT function verification, and deploying a new test scheme driven by high-precision machine vision and AI algorithm.

Test Requirements

Automated instead of manual testingSolve the problems of low efficiency, high labor cost and limited capacity expansion of offline manual testing, and realize the whole process automatic testing ICT, burning, FCT.

ICT testShort circuit/open circuit test, impedance test, electronic component function verification

Burning testMultichannel IC burning, Checksum verification, data integrity verification

Quality control and efficiency improvementThe test error rate is less than or equal to 0.5%, the repair rate is reduced by 40%, and the test efficiency is improved by 60%.

FCT testVoltage/current measurement, synchronous signal detection, visual detection of running water function of car lights.

Data management and traceabilityThrough the unified management of product information by RFID tags, bar code acquisition, MES system data transmission and traceability of test results are realized.

Embodiment

In the automation scheme, the code is uniformly scanned on the pallet and written into the RIFD label, and the barcode information is obtained by reading the information in the label, and then enters the testing machine to complete the product test. The scheme flow chart is as follows:

Automatic code scanning (manual code scanning is supported) enables the product barcodes on the pallet to pass through the centralized code scanning platform, and uniformly writes the information corresponding to the pallet into the RIFD label to ensure one-to-one correspondence of products.
