What Is A Double Sided PCB

A double-sided PCB is a critical PCB board used in electronic manufacturing.

Double-sided PCB is an acronym for double-sided printed circuit board. Path paths and line holes in these PCBs can connect electrically to various electronic components.

Moreover, we can use double-sided circuit boards for electronic communication equipment. These PCBs have high requirements. They use advanced instruments. This ensures good performance in computers. The board is often perforated in the middle to join a double-sided PCB.

The manufacturing process of double-sided PCBs differs from that of ordinary PCBs. They have an additional copper precipitation process, which turns on the double-sided circuit. Its biodegradable mesh bags will meet all your requirements.

Advantages of Double Sided PCBs

PCB productiion

A double-sided PCB board is a high-tech printed circuit board. It features two conductive copper layers on both sides, allowing it to print electrical components on both sides. Double-sided PCBs allow for more OK circuit routing. This occurs in electrical applications, leading to a higher usage rate than single-sided PCBs.


Applications of Double Sided PCBs

Double-sided circuit boards are now an essential component of electronic equipment. People’s demand for electronic devices has risen as technology has advanced.

Ultimately, it raises the need for circuit boards. Many electrical gadgets now employ double-sided printed circuit boards (PCBs). For example, mobile phones, electronic toys, and domestic appliances are notable.

Double-sided PCB boards are critical in the mass production of fixed circuits. They additionally assist in the optimization of electrical equipment arrangement. Our most common everyday applications for double blade PCBs are ARE, APPLICATIONS, UPS SYSTEMS, and others.


Difference Between Double Sided PCB and Single Sided PCB

Single-sided PCBs have parts and traces on only one side of the board. This limits design complexity and component density. Double-sided PCBs have components and traces on both sides. They offer more design flexibility, higher component density, and better performance. But they cost more to make.



Double Layer PCB Production Manufacturing Process

First, we must prepare the tools and materials to make double-sided circuit boards. The primary materials include double-sided copper-clad heat transfer paper and sandpaper. We also need scissors, an oily pen, hydrochloric acid, hydrogen peroxide, a hand drill, and a soldering iron. Moreover, we may need a twisted pair, paper tape, soldering iron, solder, rosin, and others.

The outer and inner layers combine to make a double-sided PCB board. The following mostly explains the fabrication process for the outer layer of a double-sided circuit board.

Copper plating is the first stage in manufacturing the outer layer of the circuit board’s copper processing. In the second step, the circuit is etched, and then the tin-plated is peeled off. Ultimately, the fabrication of the outer circuit is done.

Typically, industrial staff employ two ways: “Braking Optical Inspection CCD And Laser.” The first approach uses reflection effects to determine whether a short circuit exists. The second way utilizes laser AOI. After reflecting on the copper surface, it generates varied fluorescence intensities. The second way is to evaluate a short course of reflection.


We’re Here To Help You


All double-sided PCBs include two copper circuit protection layers on each side for further protection. PCB designers developed the layout of double-sided PCB boards based on single-sided PCB boards. Through-hole routing is an option for both the top and bottom circuit boards. Besides, the lines can close in on each other, and we can add new lines.
