Why do you still need single-sided PCBs?

Single-sided flexible printed circuit boards (PCBs) offer several advantages when used in packaging or as part of a system. These PCBs have been around since the 1950s and are still very popular. This article explores the reasons for their continued acclaim.

Basic structure of a single-sided flexible circuit

Single-sided PCBs consist of a single layer of conductive material, making them ideal for low-density designs. The basic structure of a single-sided flexible PCB includes:

l One layer of polyimide

l A layer of glue

l Conductor layer – copper

l A layer of glue

l One layer of polyamide

The bottom or top layers are routed or drilled to find the copper layers so external connections can be made. Like other flex circuits, these single-sided circuits also allow for a variety of general variations.

Conditions for using a single-sided PCB

Single-sided PCBs are ideal for:

l Services and installation extensions

l Small application

l Application of dynamic bending

l Abnormal forming and folding applications

l Flexible service/installation

Single-sided PCB application

Single-sided PCBs are very simple, but they can be used in a variety of complex circuits. Below are some popular applications for single-sided PCBs.

l Power

l Timing circuit

l Digital calculator

l LED lighting

l Packaging equipment

l Broadcast and stereo equipment

l Camera system

l Vending machine

l coffee maker

l Solid State Drive

Benefits of Single-Sided Flexible Circuits

The following advantages of single-sided PCBs illustrate their popularity:

l Minimal possibility of manufacturing problems: With automated production techniques and accurate design, flexible one-sided circuits reduce the possibility of human error. This suggests the least chance of a manufacturing problem.

l Affordable price: This is one of the main drivers for the popularity of PCBs with single-sided copper conductors. These circuits require less labor during assembly. Often, complete interconnect systems are replaced or installed for individual rigid PC boards. This helps reduce errors and control manufacturing costs. So, whether for prototyping, low-volume or high-volume designs, the cost is lower and the turnaround time is shorter.

l Reliability: Single-sided flexible PCB can bend and move without any chance of failure. The thermal stability of polyamide enables PCBs to withstand high and high temperatures.

l Reduced weight and reduced package size: Flexible single-sided PCBs have thinner substrates. This thinness speaks to simplified design, flexibility and resilience. This helps save weight and reduce package size. With the ever-increasing demand for low-weight circuits, single-sided PCBs are sure to continue to be popular.
