YOU NEED TO DO THE FOLLOWING:

  • Q
    How thick is the copper on the PCB?
    The inner layer of a standard PCB usually has about 1oz of copper, which is equivalent to a thickness of about 35 µ m. However, the weight of finished copper is chosen as 2oz and the thickness is about 75 µ mn.
  • Q
    How to select the thickness of PCB copper?
    You can select the thickness of PCB copper by determining the width. Therefore, if the width can withstand the average to the maximum operating temperature, that is the thickness.
  • Q
    How to remove unwanted copper from PCB during manufacturing?
    You can remove unwanted copper from the PCB by etching. The process is subtractive., Use acid to remove unwanted copper while protecting copper that needs to be left behind
  • Q
    Why does PCB use copper?
    The reason why copper becomes a member of the PCB world is that the component can effectively transmit signals. In the process, it will not lose power.
  • Q
    What is the weight of copper base?
    Base copper weight refers to the amount of copper on PCB before electroplating.
  • Q
    What should be considered for the layout of thick copper PCB?
    First, you need to consider the number of circuit layers, and then the outer layer. The number of copper/copper layers determines the number of layers of a printed circuit board.
  • Q
    What else should we pay attention to for the standard characteristics of heavy copper?
    Heat dissipation is what you need to consider. There are also heat transfer, thermal stress, thermal resistance and thermal expansion. In addition, the increased current, current, power loss, etc.
  • Q
    What should be considered in PCB industry from common design to heavy copper PCB manufacturing?
    There are many considerations on heavy copper board. First, heavy copper PCB solutions - circuit size (product size), copper PCB materials (substrate, FR4 High Tg, etc.), and then, copper thickness requirements, such as copper ounces/copper demand, heavy copper PCB thickness, and extreme copper thickness. Also. Electroplating technology for heavy copper, such as electroplating. In addition, board surface treatment, such as finishing HASL. Other heavy copper and copper electrode circuit manufacturing processes are also essential in PCB technology, such as copper etching, copper trace, solder mask.
  • Q
    Should I choose ordinary circuit board or high current circuit?
    Well, it depends on your needs. For more information about PCB manufacturing services, such as heavy copper PCB quality and circuit, please contact our team. info@camtechcircuits.com
