High Current PCB By Usage

High Current PCB

This type of PCB is required when converting DC to AC with the generated solar power energy from panels.

High Current Amplifier PCB

This type of PCB is used in some power amplifier modules. It can handle up to 10 A of current and is hybrid and modular.

High Current Transformer PCB

Transformers are used in power applications, particularly open type transformers with outputs of up to 10 kA breaking rate.

High Current Adapter Board PCB

This type of Adaptor PCB is required to deliver up to 4A current and allow you to easily plug and use your device.

Electric Vehicle High Current PCB

Because electric vehicles (EVs) operate on low voltage and high current, the controller’s current level must be controlled and precise.

DC High Current PCB

It is a PCB used in a High Voltage Direct Current PCB, also called HVDC, or a power superhighway. It allows for a huge amount of power to be carried.

High Current PCB by Feature (5)

High Current PCB by Board Type (5)

  • Multilayer PCB

    You can accomplish a lot with a Multilayer PCB. The proper amount of voltage and resistance ensures the current flow in your board.

  • Rigid PCB

    Rigid PCBs ensure consistent product performance. We incorporate PCB circuit breakers into large or thick copper PCBs.

  • FR4 PCB

    FR4 PCB meets standard regulations for use in power situations, even when dealing with high current values, such as in motor inrush.

  • ENIG PCB

    Because you can still comply with Lead-free PCB guidelines and regulations, ENIG PCB is considered a gold standard of surface finishes.

  • Customized PCB

    Customized PCBs can accommodate whatever rated values you require them to operate in, preventing shorting and overcurrent.

Possibilities With Our PCB

PCBTok’s PCBs are thoroughly tested throughout the manufacturing process before being dispatched.

This is in order to eliminate errors, and to ensure there are no mistakes occurring.

After securing your peace of mind, let’s talk about the possibilities of using this type of board. The following are applicable:

Power plants, power amplifiers, AC/DC converters (high voltage capacity), MOSFET, and especially, IGBT.

If you order from PCBTok, your High Current PCB is guaranteed to be fully operational.

High Current PCB Fabrication

Deployed For Power Applications

Our PCBs are made with well-known materials to ensure the following:

  • Safeguard against accidental grounding
  • Outdoor protection against lightning strikes
  • Keep workers safe from electrocution if they come into contact with it
  • Regulate/ control the flow of electricity
  • Complete the idealized power switch/transition

If you order from PCBTok, your product will undoubtedly be excellent.

Consider Heat Factor + PCB Layout

The end result of buying High Current PCB is safety when used with power-related gadgets.

To achieve this, your PCB designer must consider the heat factors thoroughly.

What Tg is needed, for example, for the raw materials?

The answer to this is crucial, as important as the layout.

OEM & ODM High Current PCB Applications

Mobile and Telecom

Power considerations must be considered when maximizing space and device memory in a mobile device for telecom.

Computers

A section of our OEM product line is dedicated to computer PCBs. Motherboard PCBs are considered standard items.

Power Grid & Distribution

Power Grid and power distribution require PCBs that can handle both high current and high voltage. Because power lines carry both high voltages ang high current loads.

Military Application

PCBs working in military settings must be exceptional and withstand heavy duty use, even in deserts.

Automotives

Because of the push toward electric vehicles, automotives require high current specs. It is advocated to raise the voltage level in order to maximize battery utilization.

  • “PCBTok’s service was quick and inexpensive, and the sales office staff was extremely pleasant and friendly to work with! If I ever need something more serious done, I’ll bring my PCB here first. This is my first time, but it will not be my last. They deserve credit for attempting to please their customers. I couldn’t explain their method to you, but all that matters is that I’m satisfied.”

    Edmond Black, PCB Assembler from Edinburgh, Scotland
  • “It didn’t take long for my purchase. I received my items the following week. When I first looked at the single-sided PCBs, I thought they were nice because they didn’t rush through the job. They are the experts and should be able to troubleshoot your PCB design if you require assistance. Not only did they do a good job with the PCB, but they also did a great job with the wrapping! I have faith in the PCBTok team.”

    Jasper Eleria, Purchasing Supervisor from Cayman Islands
  • “These guys are fantastic! I have no objections to the price, but PCBTok gave me a great deal regardless. They offered me a price that was half that of the nearest competitor. They were also able to finish it while I waited for a short period of time. I couldn’t believe how nice it looked when I got it. The sales girls in the office were fantastic and kept me up to date on all deadlines and prices. I will most certainly use this company again!”
