<p>Circuit board is a kind of electronic circuit, which is very common in our life. There are such items in computers, mobile phones and refrigerators. Printed circuit board is also called pcb board aluminum substrate, high frequency board, ultra-thin circuit board, ultra-thin circuit board, Printed (copper etching technology) circuit boards, etc., are the supports for electronic components and the provider of circuit connections for electronic components. The most common printed circuit boards use the method of printing etching resists to produce circuit patterns and circuits, so they are called printed circuit boards or printed circuit boards. Because people want smaller products, mobile phones are getting smaller and smaller, computers are getting smaller and smaller, and the circuit boards of <strong><a href="https://www.realteqs.com/teqsplus/read-blog/26778">FS Technology</a></strong> have become more and more refined. With the advent of the 21st century, production technology has become more and more developed. The vast majority of PCBs now use etch resists (lamination or coating), and after exposure and development, <strong><a href="https://socialsocial.social/pin/what-are-the-reasons-for-computer-damage/">PCBs</a></strong> are made by etching.<br />

<h2>The working principle of FS technology pcb</h2>
<p>PCB is manufactured by many processes, mainly including the following processes, pads, electrical boundaries, mounting holes, vias, components, connectors, wires, filling, etc. If the pcb is distinguished according to the number of layers, it can be divided into the following common types: pcb single-layer board (Single Layer PCB), pcb double-layer board (Double Layer PCB) and pcb multi-layer board (Multi Layer PCB) three types . The main processes of these pcbs have the following functions, each of which is essential:</p>
