Heavy Copper PCB Manufacturer

Heavy Copper PCB, pcb fabrication up to 12oz, large current, pcb fabrication base material is FR4/Teflon/Ceramic, pcb fabrication used in high-power power supply and motor circuits products. HUIHE CIRCUITS is one of the heavy copper PCB manufacturers, we have passed ISO9001/ISO13485/IATF16949/UL/RoHS/REACH certification.If you want to know more about thick copper pcb, heavy copper pcb, please contact HUIHE Circuits heavy copper pcb manufacturer.

The Heavy Copper PCB plating process must achieve the following aspects:

1. HUIHE Circuits heavy copper pcb manufacturer adds a certain value according to the area value calculated by the computer and the empirical constant accumulated in the actual production to ensure the integrity of the plating layer in the hole.

2. When the heavy copper PCB is electroplated for 5 minutes, take out the substrate and observe whether the copper layer on the surface and the inner wall of the hole is intact. It is better that all the holes have a metallic luster.

3. A certain distance must be maintained between the substrate and the substrate.

4. When the heavy copper PCB reaches the required electroplating time, a certain amount of current must be maintained during the removal of the substrate to ensure that the surface of the substrate and the hole will not be blackened or darkened.

5. HUIHE Circuits heavy copper pcb manufacturer according to the mechanical processing floppy disk for trial processing, the first part pre-inspection is carried out, and all the workpieces are processed after meeting the technological requirements.
   Heavy Copper PCB Manufacturer Quality Control

6. HUIHE Circuits heavy copper PCB manufacturer Strictly implements the first article inspection system to ensure that the product size meets the design requirements.

7. According to the raw materials of different types of PCBs, reasonably select the milling process parameters.

8. When fixing the position of the circuit board, HUIHE Circuits heavy copper PCB manufacturer carefully clamps it so as not to damage the solder layer and solder mask on the surface of the circuit board.

9. To ensure the consistency of the substrate dimensions, HUIHE Circuits heavy copper PCB manufacturer must be strictly controlled the position accuracy .

10. When disassembling and assembling, HUIHE Circuits heavy copper PCB manufacturer pays special attention to the barrier layer of the substrate and pad paper to avoid damage to the coating layer on the surface of the circuit board.
    Applications Of Heavy Copper PCB
    Heavy copper PCBs shine in applications that demand high power and efficient heat management. Here are some key areas where they are widely used:

Power Electronics: This is a major domain for heavy copper PCBs. They are ideal for power supplies, motor controllers, and other high-current devices. Their ability to handle large currents and dissipate heat effectively makes them perfect for these applications.
Industrial Automation: Industrial equipment often involves high-power motors, drives, and converters. Heavy copper PCBs ensure smooth operation by handling substantial currents and dissipating the generated heat.
Automotive Industry: Modern vehicles use increasingly complex electronic systems, including power converters and inverters. Heavy copper PCBs provide the necessary current capacity and thermal management for these applications.
Aerospace and Defense: These sectors demand reliable and high-performance electronics. Heavy copper PCBs meet these needs with their superior current handling and heat dissipation.
Other Applications: They can also be found in welding equipment, power distribution units, power line monitors, torque controls, overload relays, and protection relays.
Overall, anywhere you need a PCB to handle significant power and manage the resulting heat, heavy copper PCBs are a strong choice.
