PCB is a bared material board that uses printing technology to make circuit wiring, conductive patterns such as pads, and mounting holes for electronic components on an insulating substrate. It is a board with pre-designed circuit board. These boards are usually made of copper foil and etched on the surface of insulating materials (such as fiberglass, paper, Aluminum,Glass,ceramics etc.) to form electrical connection paths between electronic components.
The printed circuit board(PCB) provides electrical connections for electronic components through these conductive lines, allowing current to flow along the designed path, thereby realizing various functions of electronic equipment.Different circuit layouts and connection methods determine the functions that the circuit board can support.At the same time,It provides mechanical support for electronic components, allowing each component to be fixed in the corresponding position.It can also realize signal transmission and distribution between electronic components, and is an indispensable part of electronic products to realize their functions. For example, on the computer motherboard, complex circuit connections allow various components such as CPU, memory, and graphics cards to work together.
Printed circuit boards are widely used in various electronic devices, including but not limited to Computers, Mobile Phones, televisions, Automotive Electronic systems, Industrial Control equipment, Aerospace equipment,Medical equipment,Measurement instrument,Wearable devices etc. From small electronic devices used in daily life to large and complex industrial machines and aerospace vehicles, printed circuit boards are indispensable.
1. Layer: Single-sided/Double-sided /Multi-layer
Single-sided board: Only 1 side copper foil and components mounted on only one side
Double-sided board: 2 side Copper foils and components mounted on both sides.
Multi-layer boards: consist of multiple layers of conductive material separated by insulating layers, allowing for a higher density of components and connections.
2. Material:Rigid/Flexible/Rigid-Flexible/High Frequency/HDI /Metal Core/Glass/IC Substrate/Burn-in
Rigid PCB:Normally made of FR4, They have ability to provide a rigid structure that can support heavy components and withstand mechanical stress.
Flexible PCB:Normally made of PI (polyimide) Or PET (polyester),is a type of printed circuit board that is able to bend and twist without breaking.
Rigid-Flexible PCB:Combines both rigid and flexible board materials, allowing for increased design flexibility and durability.This unique construction enables the PCB to bend and fold without breaking, making it ideal for applications requiring a combination of strength and flexibility.
High Frequency PCB:Typically constructed using specialized materials that offer low dielectric constant ,Ultra low loss factor and Highly Heat-Resistant , such as PTFE (Polytetrafluoroethylene) or ceramic substrates. These materials help to minimize signal loss and ensure efficient transmission of high-frequency signals.
HDI PCB(High Density Interconnect):Designed for high-density applications where space is limited. This technology allows for more components to be placed on a smaller surface area, making it ideal for devices with advanced functionality in compact form factors.
Metal Core PCB:Metal Core Printed Circuit Boards (MCPCB) or a Aluminum based PCB is a type of PCB that contains a base metal(Aluminum) material to acts as a heat sink, drawing heat away from the components and helping to keep them cool.
Glass PCB:Made of glass as the main material, with a flat and smooth surface. It is generally made by mixing a variety of chemical substances and then undergoing a series of complex processes such as high-temperature melting, molding, and annealing. Its internal structure is a three-dimensional network formed by interconnecting basic structural units such as silicon-oxygen tetrahedrons. Different chemical compositions and manufacturing processes will affect the microstructure and performance of the glass substrate.
IC Substrate PCB:IC substrate (Integrated Circuit Substrate) is a special printed circuit board used to carry integrated circuit (IC) chips.Its structure usually includes substrate, circuit layer, through hole, pad and other parts. The substrate is generally made of high-performance insulating PCB materials, such as glass fiber reinforced epoxy resin.
Burn-in PCB:Burn-in Board is a printed circuit board specifically designed for burn-in testing. Burn-in testing is a method used to stress test electronic components by subjecting them to prolonged periods of operation at elevated temperatures. This process helps to identify any weak components that may fail under normal operating conditions. Burn-in PCBs are equipped with the necessary components and connections to facilitate this testing process.
PCBs are not typically sold to the public like consumer electronics products. They are customized components based on specific design requirements.When you want to purchase the PCB,you should provide manufacturing information to the PCB Manufacturer.Like:Base material,Board thickness,Copper thickness,Surface finish,Soldermask and Silkscreen Color and the special requirement.At Xinfeng Huihe Electronic Technology,we are professional and dependable enough to provide High quality PCB from prototype to series production to you at competitive price.You can easily contact Xinfeng Huihe via email.
