Do You Know The History of PCB Copper Coins?

When you think about PCB copper coin technology history, you have to go back to the early 20th century. A German legend named Albert Hanson tried to patent the printed circuit boards in that period.

The thermal control of PCB was not so good then. But, scientists tried to develop a reliable technology for ensuring smooth heat dissipation.

But, their effort didn’t work due to the economic recession of that time. Next, the hard work of many scientists brings PCB coin technology to the present level. We are here with a chronological representation-

1970

In the early 1970, integrated circuits became very popular in electronic applications. But IC can’t function in the absence of PCB. That’s why the scientists tried to upgrade PCB design with safe thermal management.

1980

In this period, computer software-based PCB design started to take the PCB copper coin technology to the next level. Electronic Design Automation allowed the designer to think about small designs.

1990

During the decade of 90, manufacturers started applying various technologies to control excessive heat dissipation. The implementation of thermal via and copper coin insertion became common in most cases.

But copper coin technology became popular in PCB manufacturing because of its tremendous positive features.

21st Century

In the 21st century, PCB makers intended to incorporate versatile functions in PCBs. So, they were looking for a technology that could maintain thermal conduction, along with fast signal transmission.

How Do You Insert The Copper Coins In PCB?

As copper is a good conductor of heat, you should insert a piece of copper into the circuit board. But how does this insertion happen? PCB copper coin technology is reliable for proper heat dissipation.

First, you need to identify the PCB component that lacks thermal control. Copper coins have different shapes and sizes. Such as

• T-coin
• I-coin
• C-coin

You need to apply suitable copper coins concerning the area and component size. After choosing the perfect PCB copper coin, you have to start routing the circuit board.

Next, it is required to laminate the printed circuit board. Then, you must metalize the PCB. Proper metalization ensures a reliable connection between the copper count and PCB.

Besides, it provides an electrical connection by using copper plating. This feature improves the heat dissipation in high-frequency PCBs and RF-based electronic applications.

This is the safest way of insertion for PCB copper coins. You should consult an experienced PCB manufacturer who has compatibility with copper coin technology. Then, you can enjoy a hassle-free copper coin insertion in your circuit boards.

After embedding the PCB copper coin, you must properly drill the copper coins and blind holes. The blind hole aspect ratio needs to be less than 1. Again, you must keep the blind hole size less than 0.1mm on the PCB copper coins.

A high cavity flatness is preferable when making embedded copper coin PCBs. You can utilize specific CNC equipment in this production.

Prepreg Processing

During the processing of PCB prepregs, You need to cut the laminate first. Then, drill it after proper processing. It is required to inspect the laminate before matching the necessary materials.

Processing Of Aluminum Foil

In this case, you have to cut the Aluminum laminate in the beginning. Then, match the accessory materials.

Inner Core Processing

It consists of the following steps-

• First, cut the laminate
• Transfer the inner images
• Check the internal etching
• Fix the inner layer holes
• Plate the holes through CCD machinery
