Thick copper pcb

    Thick copper printed circuit boards are printed circuit boards made of thick copper foil and ultra-thick copper foil. It uses conductive materials (copper foil) and substrate materials, production technology, and application fields are different from conventional PCBs, so it belongs to a special type of PCB. The vast majority of thick copper printed circuit boards are high-current substrates. The main application areas of high-current substrates are power modules (power modules) and automotive electronic components. Some of its main terminal electronic product fields are the same as conventional PCBs (such as portable electronic products, network products, base station equipment, etc.), and some are different from conventional PCB fields, such as automobiles, industrial controls, and power modules.

    Thick copper circuit boards have the following technical points:

    1. The production of thick copper circuits inside and outside layers

    2. The lamination of thick copper circuit core boards, including the resin filling of the laminated circuit and the control of the overall board thickness

    3. The influence of thick copper core board on the drilling method of laminated board

    4. Surface solder mask production of thick copper circuits

  Key points of production capacity:

    • Multilayer thick copper circuit board

      Finished copper thickness of the inner layer: 1050μm (30 oz)

      Finished copper thickness of the outer layer: 1050μm (30 oz)

    • Multilayer buried blind hole copper copper plate

    • Thick copper plate resin/copper paste plug hole

    • High TG material

    • Solder mask thickness 50μm

    • The copper thickness of the hole wall is more than 30μm
