PCBs or printed circuit boards are the silent heroes of modern electronic devices. Most users have no idea how the components in the electronic devices they know and love work together. But for engineers, OEMs and designers, there's a lot to know about PCBs.
Printed circuit board or PCB is the heart of any electronic device. It has two main functions.
1) to accommodate electronic components, connecting components for operation
2) The board itself is made of a non-conductive substrate (such as fiberglass), which is coated with copper on one or both sides. Copper conductive and etched away from the board, leaving the appropriate components to interconnect through the circuit.
The board itself consists of four key components.
Substrate - the foundation of the PCB, the substrate is usually made of glass fiber or some other non-conductive material. The substrate can be single or multi-layer.
Copper- Used to carry current, copper in the PCB replaces the wires.
Solder Resist - Metal used to create a connection between the PCB surface and the electronic components. The solder resist layer protects the electronic alignment underneath from adverse conditions.
Screen - The layer that is used to mark the connecting lines of electronic components, warnings and other feature-specific devices.
Before entering final PCB production, prototypes must be verified to ensure that all components are connected and working properly to power the device. Learn more about pcb, you can contact prototype pcb assembly supplier GreensTone.
In order to accommodate the design, application and complexity of the device, several design decisions need to be made in advance. What type of PCB is needed first? Just like an optical conduit, PCBs can be rigid or flexible, depending on the design and application of the device.
Rigid PCB - designed to not bend or deviate from its original shape or position.
Flexible PCBs - can be folded, twisted and bent into the desired configuration. They are thinner, lighter, and can accommodate unique shapes.
