What Is Circuit BoardFingers? A Brief Description

In today’s world, electronic devices are supposedly the inevitable part of the lives. Electronic devices are wondrous invention easing the comforts of life. All electronic devices nowadays run on a circuit board. These are the key components of an electronic device.

What is a circuit board?

To put in simple terms, a circuit board or PCB (Printed Circuit Board) as they are known as is the brain of an electronic device. These are physical boards made up of either plastic or resin and are soldered to connective plates made up of metals that are used for channelizing energy. The metal generally used is copper. The soldering allows electrical connection between the PCB and other parts of the device. It is worth mentioning that PCBs are not only power suppliers as they route the signals to different components of the circuits- hence brain of the device in the true sense. Copper is essential in any PCB for conduction of electricity. Circuit board fingers are present at the edge of the circuit and they function in protecting the circuit board prototype from wear and tear. These fingers are plugged in and out frequently and so they are subjected to wearing and tearing stress.

Purpose of fingers

PCB fingers are present on the edge of the board.  The primary function of circuit board fingers manufactured from top-notch circuit manufacturers like GreatPCB SMT Limited is to reduce the wear and tear stress from the circuit board. Due to its strength, the circuit board fingers enable a PCB to be connected, disconnected an again reconnected as many as 1,000 different times in different slots.

Although the primary functions of PCB fingers to provide mechanical strength, these fingers are versatile in nature and have multiple purposes like:

• Acting as interconnection points: A function of PCB fingers is to act as a connector between secondary PCB and motherboard of the device. This connection occurs through multiple females slots and the PCB fingers conduct the signals through these slots.
• Special adapters: PCB fingers helps to add numerous performance enhancers to personal computers. These enhancements by secondary PCBs include many high-end graphics and hi-fidelity sounds.
• External connections:  Different external devices like speakers, subwoofers, scanners, printers, monitors all are plugged in their specific slots which are in turn plugged into the PCBs through circuit board fingers.
• Other than the realms of personal computing, PCB fingers are used extensively in computerized industrial machinery, large equipment’s, plants, automotive factories, factory robot arms and many more.

Using of PCB fingers from best manufacturers

Circuit boards are non-functional without a properly soldered PCB finger. While fishing for PCB fingers the first feature to check is the quality standard of the PCB board provided. The best manufacturers will deploy standardizing systems like ISO 9001 for developing circuit boards with optimum performances. Also check for their customer services, technical support, expertise and experiences everything contributes to an optimally performing PCB fingers. So when looking for circuits and fingers one should always get their basic knowledge and market knowhow updated.
