    ◉ Frequently Asked Question

    How long does the test period take？

    The normal period is 5-7 working days (except the time when the sample is in the test chamber). If you need urgent help, please contact our sales or customer service.

    What are the test sample's requirements for peel strength test of metallic clad laminates?

    Peel strength test requires customers to etch samples by themselves. It can be performed with the requirements of GB/T 4722 or IPC-TM-650 2.4.8C.

    How is the test result of CAF test evaluated?

    CAF( conductive anodic filament) can be evaluated by the change of insulation resistance after testing. And the growth of CAF can also be observed by sample microsections.

    What are the pre-treatment conditions of solderability testing?

    Steam aging, damp heat and dry heat are common conditions for sample pretreatment before weldability test.

    How to choose the solderability test method?

    If there is no regulation,  it is generally recommended to choose Dip-look method for PCB sample, wetting balance method for single PCB solder plate or component pin, and wetting balance method for solder paste.
