Aluminum PCB Substrate Materials and Dielectric Materials

  • Details of the four types of aluminum PCB substrate materials are below.
  • 6061 is an Al-Mg-Si alloy. It has medium strength and good cutting performance and is suitable for CNC, V-Cut processing. Its drawback is the high price.
  • 5052 is an Al-Mg alloy. It has medium strength and good bending performance and is suitable for punch forming. And it has a fair price.
  • 3003 and 1100 are both pure aluminum. Both have good thermal conductivity and fair machining performance. And both are cheap.
  • Details of the dielectric layer are below.
  • Because both the aluminum substrate and copper circuit layers are conductive, to avoid shorts, a dielectric layer must be in between to insulate them.
  • The dielectric material that PCBONLINE uses is made of a special polymer filled with ceramics. The polymer leads to good dielectric strength, anti-aging, high bonding, and ceramic medium increases thermal conductivity and viscoelasticity. It also resists mechanical and thermal stresses during welding and operation.
  • All double-sided aluminum PCBs require ceramic-filled polymer as the dielectric layer.

Industrial 4.0 Aluminum PCB Manufacturing at PCBONLINE

  • From laminates to testing the finished boards, the whole aluminum PCB production line is fully automatic without human intervention, which ensures accuracy.
    Industrial 4.0 means full-line production. Our production machines include LDI exposure machines, automatic test machines, automatic punching machines, etc.

    Advantages of Aluminum PCBs

    • The advantages of aluminum PCBs include:
    • ● Aluminum PCB has good thermal conductivity, electrical insulation, and mechanical strength.
    • Low costs - aluminum is easy and inexpensive to extract, so aluminum PCB costs less.
    • Longer lifespan - aluminum PCB is less likely to peel off, which will further extend its shelf life.

    Aluminum PCB Examples

    "These are part of the medical-grade aluminum PCBs PCBONLINE fabricated for a client. The pads for keyboard buttons have a hole in the pad center so that gas discharges when a user presses and releases the buttons. The gold surfaces on pads have to be completely flat, without oxide or contamination. We foresaw the details before fabrication, and the order was delivered smoothly."
