    There are several methods to test the performance of a transparent PCB. Both manual and automated inspections are applicable for transparent circuit board testing. Here, some dependable tests are described for your understanding.

    Flying Probe Test

    FPT (Flying Probe Test) is beneficial for small and large-scale transparent PCB manufacturing. Here, electrical probes are set at different axes, and the FPT conductor falls these probes on the PCB surface.

    Then, you can see the voltage rating, current rating, loopholes in the circuit diagram, short connections, etc. It is required to set a specific temperature to run this test. There is no need to use additional fixtures to alter the transparent flexible PCB board. That’s why it is worthwhile for the customers having budget constraints.

    Automated Optical Inspection

    Automated optical inspection (AOI) is a reliable method for checking the features of a transparent flex PCB. A camera attached to the AOI machine takes 2D and 3D pictures of tested circuit boards.

    Then, these images are compared to the ideal transparent PCB board designs. You can identify the faults of design layout, component placements, current and voltage ratings, etc. But, it is an expensive method of PCB testing. You should indeed think of applying the AOI test for high-volume PCB manufacturing.

    Automated X-ray Inspection

    The AXI (Automated X-ray Inspection) is suitable for finding dimensional errors rather than electrical properties. In this test, the high penetrating power of X-ray is applied to check the diameter of drilled holes, solder joints, back drilling, etc. It is also a costly but rapid inspection process like the AOI test.

    Properly Tested Transparent PCB Board

    Properly Tested Transparent PCB Board

    Except for these, you need to conduct functional tests to check the practical performance of this PCB. Thermal tests, vibration tests, and etc. are effective for determining the quality of a transparent flexible PCB.

    What Is the Thickness of a Transparent Flexible PCB Board?

    A transparent flexible PCB offers outstanding dimensional stability in the case of its thickness. Its board and conductor thicknesses are suitable for numerous flexible applications.

    The average transparent circuit board thickness is around 0.38 mm. It is adequate for maintaining the transparency and bendability of this PCB.

    The most common conductor thickness is 1 oz. It is effective for proper thermal dissipation and current conduction in a Multilayer PCB Stackup. Sometimes, 0.5 oz and 6 oz copper are used in this PCB fabrication.

    The transparent flexible design allows the designer to customize the PCB thickness based on your device. So, you have the opportunity to optimize the design layout by selecting the proper thickness of a transparent PCB board.
