Different Types Of Computer PCB

We can classify computer circuit board according to the manufacturing methods, design parameters, and their applications. As computer pcbs designs become more complicated in response to customer demand, it opens the door to producing a more comprehensive range of computer pcbs.

When selecting a circuit board of computer, there are many factors to consider, including the amount of space necessary, how stress is handled, and the computer pcb’s mechanical and electrical stability. Printed circuit board in computer comes in a variety of shapes and sizes.

Computer PCBs with a Single-Sided Tray

Computer printed circuit board are most often single-sided. It features a single copper conductive layer on top of the base. The electrical components are soldered or installed on one side of the board, while the etched circuit is visible on the other side.

The conductive channels on these boards can’t cross or overlap since they have just one conducting layer. Therefore, these computer pcbs may be used for low-density design needs because of their low thickness. Calculator circuit board, power supplies, LED lighting boards, FM radios, and timing circuits are examples of low-cost electrical/electronic devices that employ single-sided computer pcbs.

Single-Sided computer pcbs Have Many Benefits:

  • Cost-effective
  • easy to mass-produce
  • It is ideally suited to low-density architecture.
  • If anything goes wrong, it’s simple to fix.
  • Simple to create

Computer PCBs with a Two-Sided Tray

A thin layer of conducting material, such as copper, is applied on both the top and bottom sides of a double-sided computer circuit board. Metal items may be linked from one side of the computer circuit board via holes in the panel.

It is possible to install electrical components on circuit boards using surface mount technology. One of the two mounting technologies, through-hole technology or surface mount technology, connects the circuits on either side of the board. When using through-hole technology, the circuit board is predrilled with holes for the lead components, then installed and connected through solder.

Computer pcbs with two layers of copper are widely used in various products, including mobile phone systems, power monitoring, test equipment and amplifiers, and HVAC and UPS systems.

Double-Sided calculator circuit boards save several unique perks.

  • Size reduction makes the computer circuit board more compact.
  • The cost is lower than average.
  • a greater degree of adaptability
  • a greater number of pc circuit board per area
  • Suitable for the most recent electrical systems

Rigid Computer PCBs

As the name suggests, Rigid computer pcbs are circuit boards that can’t be twisted or folded like flexible ones. A firm substrate serves as the board’s foundation, giving it both stiffness and strength. Layers such as the substrate and copper are attached using glue and heat to form the final product. A silkscreen is then placed on top of the solder mask layer to create the final product. When it comes to rigid computer circuit board, they might be any of the three options listed above, depending on the application. The only problem is that once they’ve been formed, they can’t be modified.

Rigid computer pcbs are used in GPS equipment, computer circuit board, laptops, tablets, mobile phones, X-rays, heart monitors, CAT scans, MRI systems, temperature sensors, control tower instrumentation, etc.

  • Rigid PCBs have many benefits:
  • Cost-effective
  • Diagnostics and repair are simple.
  • Absorb vibrations
  • Compact

Flex Computer PCBs

There are a lot of printed circuits & parts on a flexible substrate that makes up a flexible computer circuit board. Polyamide and a transparent conductive polyester sheet are typical for flexible PCBs. 

These computer circuit boards are also known as flex PCBs, flex circuits, and flexible printed circuits. They use the same elements as rigid PCBs. 

This computer pcb differs from others in that it is built with flexibility in mind during use. As a result, the unit assembly is simpler to put together. Single-sided, double-sided, and multilayer versions of these PCBs are all available.

There are a variety of applications for flexible PCBs in the electronics industry, including the production of organic light-emitting diodes (OLEDs), LCDs, and flexible solar cells. However, it is not for printed circuit board in computer.

Advantages of flexible printed circuit boards are:

  • Cut down on clutter by doing away with connections.
  • Regulating the temperature
  • Boost consistency and dependability
  • Ensure high-speed circuitry has consistent electrical properties.
  • Suitable for uses requiring a high density of signal traces

Computer PCBs with a Rigid-Flex Design

Flexible and stiff computer pcbs have been combined to create the Rigid-Flex PCB, which may be folded or continuously bent into a flexible form or curve throughout the manufacturing process.

When interconnecting rigid boards, the flexible part of the board is employed since it allows for thinner conductor lines to take up less space, resulting in a smaller board overall. Using flexible computer pcbs for interconnections reduces the weight of rigid-flex printed circuit boards by eliminating the need for bulky connectors. 

Because these boards are 3D-built and may be folded or twisted to generate the necessary form for the product, rigid-flex PCB designs are more complex. Using 3D design to create a board allows for better spatial performance, which may be employed in medical equipment to save space and weight.

Rigid-flex boards may be compactly built, and their small weight makes them a good choice for main printed circuit board in a computer, a wide variety of aeronautical, medical, and consumer electronics applications.

There are many advantages to computer pcbs with a Rigid-Flex Design:

  • Flexibility to bend in any direction
  • Reduced the need for storage space due to 3D capabilities
  • Shock absorption
  • Improved trustworthiness
  • It’s not heavy at all.
  • Fewer solder joints ensure more excellent connection reliability.
  • Streamlined PCB assembly

Computer PCBs with Extremely High Frequency

Computer PCBs used in the 500MHz–2GHz frequency band is known as high-frequency PCBs. Microstrip PCBs, communication systems, microwave PCBs, and other frequency-critical applications all employ these PCBs.

Computer PCBs with aluminum backplates

As a result of the aluminum composition, these PCBs are employed in high-power applications to dissipate heat. The stiffness and minimal thermal expansion of aluminum-backed PCBs make them excellent for applications requiring great mechanical tolerance. 

Factors That Influence Computer Ups Circuit Board Price

The kind of material, board size, and the number of layers are the three elements that most influence PCB manufacturing cost breakdown. The finish and the size of the holes, including these eight, may also influence the pricing.

Material Choice

The cost of a computer circuit board is directly related to the materials used in its construction. When it comes to high-intensity boards, such as those used in the aircraft and petroleum sectors, standard PCBs are laminated with FR4 material.

Thermal Reliability:  Can the computer pcbs handle the high temperatures required to complete the tasks? Materials for high-thermal rating boards must be used on specific circuit boards.

Temperature Reliability: Is the material temperature reliable in ambient conditions without overheating? Materials that pass these tests are required for computer pcbs designed for use in high-temperature environments.

Heat Transfer: Is the board capable of handling high-intensity loads without overheating connected and neighboring components? 

Signal Performance: Can it run without interruption, regardless of how long it’s been idle? Exactly what temperature and other external conditions will not affect the signal? These issues are crucial to the overall PCB performance.

Mechanical Properties:  Does it have the physical composition to handle a reasonable range of stresses? Is it possible to squeeze the computer pcb into a small space without it cracking?

Durability: Can it be dropped many feet without breaking? Drop testing, and other performance standards must be met before a computer pcb ideal may be sold.

Size of the Computer PCB

The size of a computer pcb and how much of the board is used will significantly impact the pricing. The number of circuits needed for a particular device will dictate the size of the computer circuit board.

A PCB in a digital watch, for example, will have fewer components and be less expensive to create than a computer PCB. Similarly, a PCB in a big industrial machine will be larger than those found in most consumer devices.

The number of Layers

The number of layers of a board is also a deciding element in its cost. For obvious reasons, PCBs with three or more layers cost more to create than boards with just two layers. The kind of material used and the board’s size have an impact on the cost. It takes a lot more labor to make thick boards with several layers.
