Single Layer PCB

What Is Single Layer PCB?

A single layer PCB is type of PCB that is made of substrate material which is typically fiber glass or an equivalent material with conductive copper channels. Traces are used to link the various components that are installed on the board of single layer PCB. Single layer PCBs are usually made for simplest electrical devices for simple circuitry. Single layer PCBs hold a unique position due to their less expensive in cost then multilayer PCB’s. Below are the mentioned capabilities, detail structure and application about single layer PCB’s

The Single Layer PCB Structure

The single layer PCB is consist of only one sided copper (conductive copper) over the non conductive PCB substrates. Below is the overview of its structure:

Substrate (Base Material)

Substrate is a base material made from epoxy resin fiber glass, which helps as a mechanical support for rigid PCB’s, current insulation and helps keep all copper layer separate.

Copper Layer

The copper layer work as a conductive & primary layer in PCB. Which allows a PCB design to complete its nets connections through Traces, Pads and Via’s. There are multiple copper thickness which we offer for single layer PCB’s

Solder Mask

A polymer layer that is usually green, also it comes in other colors. It protects the copper traces from oxidation and prevents solder bridges between solder pads during the soldering process.

Silkscreen

A non-conductive ink, often white, but can also be yellow, black, or other colors. The purpose for printing silkscreen on PCB’s is to provide reference designators, UL & Date code markings and other information to help during assembly and troubleshooting.

Stackup of Single Layer PCB's

A designer has to ensure to keep the right arrangement of components and conductive traces without any short, open or missing nets. This process, known as layout design, involves strategically placing ground and power connections to maintain signal integrity through precise calculations as per the functional needs of the circuit.There are following consideration when one is planning single layer stackup:

Signal Integrity
EMI/EMC Considerations
Power Distribution
Component Placement and Routing
Thermal Management
Reliability and Long-term Performance
Mechanical Strength and Durability
Manufacturability and Cost Constraints

Applications & industries of Single Layer PCBs

Single-layer PCBs are used in many different applications and for various industries which are as following:

Consumer Electronics
Automotive Electronics
Home Appliances
Educational and Prototyping Purposes
Communication Devices
Audio Devices
Toys and Gadgets
Lighting Solutions
Office Equipment

Single-layer PCBs are still essential in many applications where easy application, cost, and fast response are important considerations. Engineers and producers must comprehend their applications, structure, and stack-up details. By using their strengths through thoughtful design and consideration, one can successfully utilize the advantages of single-layer PCBs in different applications including, home appliances, educational and prototyping purposes.
