  • VT-42 CCL/Laminate VT-42 PP/Prepreg (Standard FR4 Material)

    UL Approval: E214381 Version: Rev. B4 17/12/2017 /21

    Storage Condition & Shelf Life

    Precautions In Handling

    • The prepreg exceeding shelf time should be retested.
    • Take care in handling thin core laminates as they are easily damaged.
    • If the prepreg is not consumed within 48hrs after opening the vacuum package, it is recommended that the bags be resealed.
    • Material is available in both long and short grain. The grain direction is indicated on the label with an arrow.

     

    Designing And Inner Layer Process

    • Please be careful when single ply of 1080, 1086, 1078 or 106 prepreg is designed to the dielectric layer.
    • Dimension stability is the same as Standard FR4 material.
    • Please check with your oxide vendor to make sure that our material is suitable with your oxide process. We recommend to control the peel strength with brown oxide copper over 2 Lb/in.
    • For unclad or single sided laminates to be used in multilayer, please brush unclad sides before use.

     

    Prepreg Availability

    E-Glass styles: 7628, 1506, 1500, 2113, 2313, 3313, 2116, 1080, 1086, 1078, 106, 1067 etc.

    ① Press thickness test condition---Prepreg lamination size 18”*24”, Copper Foil---1oz/1oz, Flow---about 5%; ② Make laminated pre-preg to micro-section and measure the thickness with microscope; this thickness is used for resistance design calculation. ③ The thickness measured with micrometer is 0.2~0.4 mil larger than that measured with micro-section; and mainly used for total thickness design calculation.

    Laminate Availablity

    Thickness: 0.002” (0.05mm) to 0.200” (5mm), available in sheet or panel form Copper Foil: 1/4 to 12oz, HTE or RTF or DST DK values are for impedance design.
