What are the disadvantages of PCB?

Disadvantages of PCB :

• Uneven PCB surfaces finish.
• Not good for fine-pitch.
• It contains lead.
• Thermal shock.
• Solder bridging.
• Not easy to repair once damaged.
• It can be used for a specific circuit.
• We cannot be updated, once printed.

What are the features of flexible PCBs?

Flexible Printed Circuit (FPC) a highly flexible and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good bending property.

What is Flexi PCB?

A Flex PCB or FPCB is a patterned arrangement of printed circuitry and components that utilizes flexible based material with or without flexible coverlay.

Where is flexible PCB used?

Flex circuits are being used in electronics such as calculators, cell phones, printers, LCD televisions. Cameras. They are used in the medical fields in heart monitors, pace makers, hearing aids. They are used in manufacturing of robotic arms, processing machines, bar code equipment etc.

What are the advantages of flexible PCB?

In many applications, flexible PCBs can eliminate the need (and cost) of connectors and cables, improving connection reliability and reducing assembly time, assembly costs and overall device dimensions.

What are the advantages of flexible PCBs?

The advantages of using a flexible PCB

• Reduce weight and space.
• Meet dynamic flexing requirements.
• Flexing for easier installation and service.
• Increase reliability and repeatability.
• Thermal management.
• Improve aesthetics.
• Eliminate connectors.
• Provide uniform electrical characteristics for high speed circuitry.

What are the advantages of flexible PCBs Mcq?

Advantages of flexible PCBs Being flexible, FPCs can bended and flexed, allowing greater freedom in the design and operation of the application. Flexible circuits can also adapt to small or irregularly shaped spaces, a feature not supported by standard rigid circuits.

What are advantages of flexible PCBs?

Why flexible PCB are used?

Flexible PCB Applications. Flexible circuits and their board types are often used when reliability and maximum adaptability are needed. If a circuit needs to be bent during package assembly, flexible design is required. They are also ideal when flexing and warping cannot be avoided.

What is PCB design advantages of PCB?

Some advantages offered by these PCBs are: These PCBs help save a lot of space, along with reducing the overall board weight. Flexible PCBs helps in decreasing the board size, which makes it ideal for various applications where high signal trace density is needed.

What are the advantages of rigid-FPC PCBs?

FPC also has the advantages of good heat dissipation, good solderability, easy assembly, and low overall cost etc. The design of Rigid-flex PCB also compensates for the insufficiency of the flexible substrate in terms of component carrying capacity.

What are the limitations of FPC?

FPC are usually manufactured by a batch process in the absence of a conventional process, It cannot be made very long and wide size because of the limitation of the size of the production equipment. FPC is easily damaged by improper personnel operation. Its soldering and rework requires the operation of trained personnel.

What are the advantages of FPC plating?

Therefore, FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDAs, digital cameras and other fields. FPC also has the advantages of good heat dissipation, good solderability, easy assembly, and low overall cost etc.

What is a FPC circuit?

FPC are printed circuits made of flexible insulating substrates that have many advantages: It can be freely bent, wound and folded, which can be arranged arbitrarily according to the space layout requirements, and can be moved and expanded in any space in three dimensions.
