A single-sided PCB is the most basic type of printed circuit board. It has only one conductive copper layer on top of the substrate. Some parts of the board are connected by solder, while the rest of the board has a circuit that can be seen. The overall single-sided PCB consists of a substrate layer, a conductive metal layer, and a protective soldermask and screen-printed layer. Single-sided PCBs were the first printed circuit board technology and have been popular since the 1950s. They are still used a lot today because they are simple to design.

Features of single-sided PCB
1. Cost-effective: Compared to multi-layer PCBs, single-sided PCBs require less material and processing, which reduces production costs. This makes it easy and fast to produce large quantities, which reduces the time it takes to get products to customers and makes it the best choice for high-volume production. This can save both manufacturers and consumers a lot of money.
2. Simple design and manufacturing: The design process for single-sided PCBs is relatively simple, and it reduces the time and expertise needed to create a single layout. The simple design also makes manufacturing simple, reducing production errors across all industries.
3. Easy to maintain and modify: Due to its simple design, the single-sided PCB is very easy to maintain. All the parts are on the same side. So, it's not hard to test and repair them. It's also simple to modify and update the board without having to do a lot of work on the multilayer PCB.
However, single-sided PCBs have some disadvantages. These boards have only one conductive metal layer, so you can only arrange circuits on one side of the board. This also means that the paths created by the conductors can't cross or overlap with each other. This makes it hard for the board to efficiently connect various PCB components. Designers need to use jumpers to achieve the necessary lengths, which can further increase the complexity of the circuit's assembly process. Single-sided PCBs usually don't use space as efficiently as multilayer PCBs.
Single-sided PCB applications
Daily applications should have a simple design that is both affordable and easy to maintain. Single-sided PCBs were created for this purpose. They are typically used in low-cost, low-density electrical and electronic equipment. Many appliances still use single-sided PCBs.

1. Consumer electronics: These boards are usually used for home electronics. These devices require strength, durability, and high functionality, from calculators to digital cameras. These applications don't require high-frequency PCBs, so single-layer PCBs can meet their circuit needs.
2. Power Supplies: Many basic power supply circuits also use single-sided PCBs. These boards are good for simple layouts. Power regulators, transformers, and capacitors often use this simple layout. Single-sided PCBs are a reliable platform for devices that require power conversion and management.
3. LED Lighting: LED applications, especially in lighting fixtures, usually involve simple circuits. Most of them are inexpensive and have low production costs. For this reason, single-layer PCB boards are usually chosen.
4. Automotive components: In the car industry, single-sided PCBs are used for dashboard indicators, lighting systems, and other equipment. These components don't require complex circuit design. Single-sided PCBs are perfect for these applications. These boards also help make these car parts more durable.
5. Industrial Applications: Many control systems and sensors are used in different types of industries. Single-sided PCBs are often used for these applications. These boards are easy to install and require little maintenance.
Summary
In today's ever-changing electronic technology, single-sided printed circuit board continues to write an industry legend with their unique technical value. Born more than half a century ago, this technology has not only witnessed the vicissitudes of the electronics manufacturing industry, but also in the wave of intelligence to show amazing adaptability. From the temperature control module of smart homes to the BMS monitoring unit of new energy vehicles, single-sided PCBs have always occupied the core position of basic electronic module manufacturing due to their inherent cost advantage and process stability.
