PCB 1 layer

A single-layer or single-sided PCB is made from a single layer of base material or substrate covered with a thin layer of copper. In addition to the copper part, a protective mask called “Solder” is usually applied, normally followed by a last silkscreen mask called “Symbology” which is used to indicate all the components of the circuit.
Single-sided PCBs are simple to manufacture with a relatively low cost for this, where possible, they are often used in the creation of circuits for domestic appliances and large-scale commercial equipment.
Surface finishes are available for single-sided boards including Organic Solderability Preservatives (OSP), Immersion Silver, Tin and Gold plating or HASL with lead or lead-free.

Advantages of single-sided PCBs

• Ideal for simple low-density projects
• Cost reduction, especially for high volume orders
• Less chance of production problems
• Popular, common and easily understood by most PCB manufacturers
