PCB is the abbreviation for printed circuit board in English. Printed circuits are commonly referred to as conductive patterns made of printed circuits, printed components, or a combination of the two, based on predetermined designs on insulating materials. The conductive pattern that provides electrical connections between components on an insulating substrate is called a printed circuit. In this way, printed circuits or finished boards of printed circuits are called printed circuit boards, also known as printed boards or printed circuit boards. On the most basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Because wires only appear on one side, we call this type of PCB a single sided PCB. Because single sided PCBs have many strict limitations in circuit design, as they only have one side, the wiring cannot intersect and must be routed independently.

Flexible PCB has been widely used in the market and has become an indispensable product in the electronics industry. It can adapt to various applications of flexible PCBs, such as wearable devices, artificial organs, medical devices, RFID modules, etc. Rigid flexible PCB is a substitute for rigid PCB, made of PCB material but with bending characteristics. The combination of rigid and flexible PCB is mainly used for mobile phones and wearable products. Both semi flexible and rigid flexible PCBs provide sturdy designs with additional flexibility to move or shake product components.

Rigid flexible PCBs can be bent, folded, or rounded, and then integrated into various products. They provide convenience, flexibility, and mobility for portable devices. They include expansion cards and batteries on laptops or desktop computers. A semi flexible PCB can be bent or bent, but it is not as flexible as a rigid flexible combination board. They are also an effective portable device solution because they do not require rigid connections in areas with high pedestrian traffic, as they can bend without breaking or separating. This blog post will delve into various applications of rigid flexible PCB and semi flexible PCB design.

Printed Circuit Board (PCB), also known as Printed Circuit Board or Printed Circuit Board. Multilayer printed boards refer to printed boards with more than two layers, which are composed of connecting wires on several layers of insulating substrates and solder pads used for assembling and welding electronic components. They not only have the function of conducting the circuits of each layer, but also have the function of mutual insulation.

PCB multilayer board refers to a multi-layer circuit board used in electrical products, which uses more single or double-sided wiring boards. A printed circuit board that uses one double-sided inner layer, two single-sided outer layers, or two double-sided inner layers, and two single-sided outer layers, and is interconnected with conductive graphics according to design requirements through positioning systems and insulating bonding materials, becomes a four or six layer printed circuit board, also known as a multi-layer printed circuit board.

The metal insulation base is composed of a metal base layer, an insulation layer, and a copper clad circuit layer. It is a metal circuit board material that belongs to electronic general components, consisting of a thermal insulation layer, metal plate, and metal foil. It has special magnetic conductivity, excellent heat dissipation, high mechanical strength, and good processing performance.

The metal insulation substrate is composed of a metal substrate layer, an insulation layer, and a copper clad circuit layer. The top layer is a copper clad circuit layer, which initially consists of a layer of copper. According to electrical interconnection requirements, the circuit can be corroded into the required circuit. The power transistor core, driver control chip, etc. can be directly soldered onto the copper clad circuit layer. In order to facilitate welding and prevent oxidation, the solder pad is coated with Ti, Pt, Cu, Au and other gold thin films, with thickness sizes of 35, 50, 70105140 microns; The intermediate layer is an insulating medium layer, usually made of epoxy glass fiber cloth adhesive with good thermal conductivity, epoxy resin, or organic dielectric film filled with ceramic materials. Its thickness is divided into four specifications: 50, 75, 100, 150 microns.

High frequency PCB board refers to a special type of circuit board with high electromagnetic frequency, used in the fields of high frequency (frequency greater than 300MHz or wavelength less than 1 meter) and microwave (frequency greater than 3GHz or wavelength less than 0.1 meter). It is a circuit board produced on a microwave substrate copper clad board using some processes of ordinary rigid circuit board manufacturing or special processing methods.

The heavy copper PCB segment is a growing part of our production. In order to support this important segment, we are developing long-standing relationships with several factories which are carefully selected in our sourcing process.

HDI PCB (High Density Interconnect PCB) is a high-density interconnect circuit board used to achieve more connections and higher density in limited space. It is typically used in complex electronic devices such as smartphones, tablets, and computers.

The HDI PCB circuit board adopts a series of advanced manufacturing technologies, such as micro circuits, blind buried holes, embedded resistors, and interlayer interconnections. These technologies enable HDI PCBs to achieve higher connection density and more complex circuit designs in relatively small sizes.

Due to the manufacturing process and high precision requirements of HDI PCB circuit boards, the manufacturing cost of HDI PCB is usually higher compared to traditional ordinary circuit boards. This is because HDI PCBs require the use of more complex processes and advanced equipment to achieve their high density and complexity.

In addition, the design and layout of HDI PCB circuit boards also require more engineer resources and time investment to ensure the reliability and performance of the circuit.

Therefore, in general, the manufacturing cost of HDI PCB circuit boards is higher than that of traditional circuit boards. However, the specific cost influencing factors are also influenced by many other factors, such as the required number of layers, line width/spacing, aperture requirements, etc.

FPC (Flexible Circuit Board) is a type of PCB, also known as a "soft board". FPC is made of flexible substrates such as polyimide or polyester film, which has the advantages of high wiring density, light weight, thin thickness, flexibility, and high flexibility. It can withstand millions of dynamic bends without damaging the wires, and can move and expand according to spatial layout requirements to achieve three-dimensional assembly, achieving the integration of component assembly and wire connection. It has advantages that other types of circuit boards cannot compare.

FPC is widely used in mechanical sensitive devices because its flexibility allows circuit boards to resist vibration. Flexible PCBs are more durable than traditional circuit boards, but their manufacturing process is sensitive and complex.

Double-sided PCB board is a very important type of PCB board in the circuit board market. There are double-sided PCB boards with metal base, Hi-Tg heavy copper foil circuit board, flat and winding double-sided PCB boards, high-frequency PCB boards, mixed dielectric base high-frequency double-sided PCB boards, etc. It is suitable for a wide range of high-tech industries such as telecommunications, power supply, computers, industrial control, digital products, scientific and educational instruments, medical equipment, automobiles, aerospace defense, etc.

Many users of PCBs find ceramic PCBs have an advantage over traditional PCBs made of other materials. This advantage is because ceramic PCBs provide suitable substrates for electronic circuits with high thermal conductivity and low coefficient of thermal expansion (CTE).

The ceramic PCB is extremely versatile and can replace a complete traditional PCB with a less complex design and increased performance. You can use them in multiple products, like high-power circuits, chip-on-board modules and proximity sensors.
