LED printed circuit boards at ABL

Many clients rely on ABL Circuits to design, prototype, manufacture and assemble their custom LED PCB projects with unerring accuracy. As well as guaranteeing our clients’ satisfaction in a job done right the first time, every time, we also offer some of the fastest lead times in the UK.

What is an LED PCB?

LED PCBs are specific types of printed circuit board, designed for use in a wide array of lighting modules and applications. A number of light emitting diodes (LEDs) are mounted to a PCB forming a completed circuit, allowing full control of their behaviour through various types of chips or switches.

What are they used for?

Countless industries and applications rely on LED PCBs to control lighting arrays in multiple devices and setups. Common examples include:

  • Automotive lighting
  • Street and tunnel lighting
  • Indicators and display panels used in telecoms devices and computing
  • Torches, flashlights and work lamps
  • Signal lighting
  • Medical room and device lighting

LED PCBs have a number of distinct qualities and characteristics that make them especially well suited to these kinds of uses. Among the most important are:

  • Economy – LED components are fairly cheap to buy, and very efficient to run
  • Reliability and longevity
  • Low power draw
  • Low profile, lightweight
  • Fairly resistant to the effects of dirt and moisture ingress
  • Versatile – highly programmable, and sold in a diverse array of colours/sizes

What are the main challenges of LED PCB assembly?

There are several unique considerations to bear in mind when designing, assembling and manufacturing LED PCBs. Chief among these is often thermal management.

Most surface-mounted light emitting diodes are relatively cool-running semiconductors. However, more powerful lighting arrays often feature multiple high-intensity LEDs arranged in close proximity on a single board. These sorts of designs can output significant heat over a relatively short space of time, which needs to be dissipated effectively in order to improve the overall performance, reliability and durability of the circuit and its components.

There are a number of ways to improve heat management when prototyping and assembling LED PCBs; smart design and precision prototyping are always the first steps. However, more densely packed circuits may require the use of additional components and manufacturing techniques – such as heat sinks or metallic board substrates – in order to improve dissipation.

Ian - MES

First time user of ABL and placed an order for a 4 layer board with 2oz copper on all layers. Order received in 5 days and the quality of the board was excellent. Probably the best quality of board that I have received from using countless suppliers. Would definitely recommend ABL for PCB manufacture and will be using them again for my next PCB request.


Very nice company to work with as they are always happy to help solve any of my problems fast and good quality work. They are my number one PCB supplier.


Excellent service, fast and efficient with excellent help during the development of the circuit design. Great pricing structure and very professional.
