10 oz Copper PCB By Feature

High CTI Carbon Ink PCB

This PCB provides 175 to 600 levels of protection against environmental stressors such as dirt and excess moisture.

FR4 Carbon Ink PCB

This type of substrate, known as FR4, is compatible with the use of carbon ink. PCB Etching and PCB Routing are also applicable.

Polyimide Carbon Ink PCB

We can use Carbon Ink printing on Polyimide substrates. Switch to polyimide if you need High Tg PCB or Flex PCBs.

PTFE Carbon Ink PCB

Another platform where Carbon Ink printing is used is PTFE. PTFE or Teflon PCB is good if you need to meet outgassing requirements.

Silver Ink PCB

In FPC and Flex PCBs, Silver Ink PCB or Nano Silver is used. It is also known as conductive silver PCB ink by some suppliers.

Conductive Carbon Ink PCB

Conductivity is a property of Carbon Ink PCB. Its primary function is to connect traces on the board.

Carbon Ink PCB By Usage (5)

  • Remote Control PCB

    Superior PCBs for remote controls are designed to withstand repeated touching and manipulation. It’s mostly made of Rigid types of PCB.

  • Contact Point Carbon Ink PCB

    Contact Points are the pinnacle of Carbon Ink on PCB application. The webbing attachment, which comes with typical product specs, enables the tactile responses.

  • Keyboard PCB

    Another subset of Carbon Ink application on PCB is keyboard PCB. Examples include digital or electric piano keys and a computer keyboard.

  • Welding Machine PCB

    Welding Machine uses Carbon Ink on PCB because this industrial-grade machine requires very tough PCB. With daily use, there’s heavy button pressing.

  • RF Shield PCB

    This product uses Carbon Ink to protect against electromagnetic shielding and unwanted radio frequency interference (RF). RF PCB items are also available from us.

Carbon Ink PCB By Layer & Board Type (6)

  • Single-Layer PCB

    The best value is provided by single-layer PCB. Customers who use it sell simple gadgets like those typified by appliances.

  • Double-Layer PCB

    Because this ink printing on a PCB surface is less expensive, double-layer PCBs, such as those used in appliances, are also applicable.

  • Multilayer PCB

    However, multilayer PCB can be accommodated for the PCB using carbon conductive ink. Primarily made of FR4.

  • Rigid PCB

    Rigid PCBs must withstand environmental stresses such as heat exposure. As a result, a high CTI is a common basis for evaluating.

  • Rigid-Flex PCB

    The Rigid-flex PCB is an outstanding product for product designers, particularly those who create smartphones and other mobile devices.

  • Flexible PCB

    Of course, the Flex PCB has a place among PCB designers due to benefits such as adaptability, ability to fit into small spaces, and durability.

Quick Quote
  • “Your men checked and measured everything and then emailed us a quote later that evening that was significantly less than what we expected. The previous PCB Supplier estimated the job to be twice as expensive as what PCBTok quoted. For lighting, we needed a new multilayer PCB. Because the design is complicated, the other contractor would not have bothered to try. PCBTok did an outstanding job with our order, going above and beyond to ensure that everything was a beauty.”

    Sal Hemminger, Supply Chain Manager from Buckinghamshire, England, UK
  • “PCBTok assisted us in diagnosing our PCB problem in less than 12 hours and fixing it in an hour after EQ requested it. If you are unsure about your PCB project and require experts, I highly recommend them. They’ve never attempted to upsell me on anything. The saleswoman who spoke with me had a pleasant voice and was as professional to work with as you could imagine. Highly recommended. “

    Dennis Catuira, PCB Assembler from São Paulo Brazil
  • “PCBTok They are proud of their work. I needed a great system two years ago, but it got delayed, and now I’ve found the time to switch to a Chinese manufacturer. When the time came, they walked me through the entire process, beginning with the estimate. It was worthwhile to visit this company. My post-work inspection was successful! They did thorough and clean work.”
