What is the Small PCB Fabrication flow path

Discussion in 'Tin Tức' started by jackwong1931, May 10, 2019.

  1. Many engineer and purchase want to find a supplier to production them PCB direct, but they do not know what is the small PCB fabrication flow path and how to calculate the cost, here I will introduce the standard PCB fabrication flow and the cost calculate on PCBA Store,



    The standard PCB fabrication flow

    a, Design
    The different board has a different function,for a particular product and must be designed to perform that function in the space allotted. Board designers use computer-aided design systems with special software to layout the circuit pattern on the board, normally Gerber file is most popular,



    b, Raw material choice
    [​IMG]



    The substrate most commonly used in printed circuit boards is a glass fiber

    reinforced (fiberglass) epoxy resin with a copper foil bonded on to one or both sides. PCBs made from paper reinforced phenolic resin with a bonded copper foil are less expensive and are often used in household electrical devices,

    c, Supplier production process


    1,Copper coated laminate

    2, Cutting the board

    3, Inner layer graphics transfer
    4, laminated-Stack

    5, Drilling hole, PTH

    6, Outer layer graphics transfer

    7, Graphic plating

    8, Outer layer etching

    9, Photoresistive soldering

    10, Surface treatment process

    11, V-cut

    12, E-test

    13, FQC, FQA

    14, Packing

    Small PCB fabrication cost on PCBA Store


    The main effects for PCB is material, layer, size(dimensions), thickness etc,

    PCBA Store support online quote, you can enter these properties and flow the step, then you can get the quote directly from the web, it’s very convenient for your budget,



    This article for standard PCB fabrication, someone has the doubt for the difference on the standard PCB production and PCB fabrication prototype, in next time will write this.
