Hard gold PCB is a printed circuit board with a layer of hard metal plated on its surface. This hard metal not only enhances the PCB’s abrasion and corrosion resistance, but also greatly improves its electrical conductivity, making hard gold PCB in high-frequency, high-speed, high-current electronic equipment outstanding performance.
Application of Hard Gold PCB
Hard gold PCB has become the ideal choice of circuit boards in many fields. Especially in the field of industrial intelligent machinery, we can often see its figure. Whether it’s entertainment, artificial intelligence or educational robots, you can find traces of these circuit boards. In fact, hard gold PCBs are widely used in various electronic devices, such as cell phones, computers, and other devices. The ability of hard gold PCBs to maintain a stable electrical connection makes it a suitable choice for all types of applications.
Computer Systems
Hard gold PCBs are widely used in computer systems. Whether it is a laptop or a desktop computer, these circuit boards play a vital role. Signal integrity and data transmission are critical in computer systems, and the excellent performance of hard gold PCBs meets these needs.
Telecommunications Systems
Hard gold PCB is also ideal for telecommunication systems. These boards play a key role in cell phones, GPS and satellite systems. They ensure the efficient and stable operation of telecommunication equipment and guarantee the quality and stability of signal transmission.
Industrial Systems
In mechanized equipment, we often find the use of hard gold PCB. Since computer-controlled industrial machines need to withstand a variety of harsh environments and working conditions, hard gold PCBs with their unique characteristics are the first choice for such applications. Its resistance to corrosion and abrasion makes this type of circuit board ideal for use in such environments.
Consumer Electronics
Hard gold PCB has excellent resistance to corrosion and high temperatures. Gold has good electrical conductivity, which allows it to withstand high temperature environments without damage. As a result, hard gold PCBs are widely used in consumer electronics such as smartphones, TVs, and smartwatches.
Impact of Underlayment on Hard Gold PCB
Gold is able to provide greater advantages when used in combination with other metals. One of the distinguishing features of hard gold PCB is that they usually have a layer of nickel on the substrate. This layer of nickel sits underneath the gold plating. There are several benefits to using this base layer of gold plating. First of all, the base layer provides the board with additional protection against any form of corrosion. Sometimes, corrosion may seep through certain pores in the gold plating, and the presence of the nickel underlayer effectively prevents this from happening.
