    CPU PCB: The Ultimate FAQ Guide

    You might have a CPU in many electronics you use. For example, CPU PCB is used in your smartphone, computer, and devices like those. Your computer keyboard, monitor, printer, everywhere you will have microcontrollers (CPU) that use CPU PCBs.

    If you are looking for a way to know about CPU PCBs, you landed in the right place. Here we have collected various knowledgeable questions about CPU PCB and are going to clear them to you.

    Let’s move to the point.

    What Is CPU PCB?

    PCB or the printed circuit board is the base of electrical components used to power up and conduct the workability of the electronics.

    It is mainly made of an electrically conductive material such as copper, which is etched to conduct the current flow. The base block is made of different non-conductive materials such as prepreg, TEFLON, etc.

    A CPU PCB

    A CPU PCB

    A CPU PCB is a printed circuit board that holds the computerized device’s controllers or central processing unit-CPU. The PCBs also include modular PC cards, peripheral component interconnect-PCI, industry-standard architecture. The genre extends with PCI extension for instrumentation card- PXI, and the embedded technology extended-ETX.

    How To Design A CPU PCB?

    There are some fundamental differences between typical PCB designing and CPU PCB board designing. You will have to follow some extra steps to complete a PCB design. Here you will see how to design a CPU PCB with multilayer boards.

    Choose The Component Mounting Technology

    There are two types of component mounting technology you will find: through-hole and surface mounting. The components could be positioned through the surface mounting process by an automated machine.

    Through-hole allows you to place the components by drilling the base of the PCB. So, you determine which method would be preferable for the particular design.

    Determine The Microcontroller

    The central part of the CPU PCB is the microcontroller. Choose a suitable microcontroller for the proper purposes. Consider the overclocking speed and performance of the microcontroller.

    Choose The USB To Serial Converter

    The CPU will need to interface with the computerized system to operate the performance. An external chip is needed here to assist the translation to the automated system through a USB port.

    The signal can be accessed on the microcontroller using serial communications peripherals such as the UART.

    Choose The Analog To Digital Peripherals

    The right analog to digital signal converter is essential to convert your analog signals into digital and enhance usability. Determine which one you will use.

    Analog To Digital Signal Converter Module

    Analog To Digital Signal Converter Module

    Design The Circuit

    Design the circuit by drawing the schematic design of the board. The schematic is the visual of the CPU PCB, which shows how the PCB will be. Schematic is the blueprint of your PCB.

    Check here how to design your microcontroller board:

     

    Design The CPU PCB Layout

    PCB layout is the most crucial part of PCB designing. The layout design is impacted by choosing the characteristics of the analog signals. Ground plane also should be considered to design the layout of the PCB.

    Analog signal traces must be kept away from the high-speed digital traces in the layout.

    Order The PCB Stackup

    The arrangement of the CPU PCB layers is essential for the performance, conductance. So, consider the following things during the PCB design.

    • Number of the PCB layers
    • Layer order
    • Space among the layers
    • Purpose of each layer
    • The thickness of the layers, etc.

    Choose The Right Components

    Right components for the proper purposes are essential. The parts you selected should meet your requirement in terms of the intention to use your CPU PCB.

    PCB Fabrication And Assembly

    Now the CPU PCB board is ready to be fabricated and assembled. The thermal paste on PCB, such as solder mask, should be used to coat the PCB board.  Other PCB fabrications such as photoresist, surface finishes should be appropriately applied.

    Assemble the right components in the right place of your PCB, and solder them if you choose the through-hole mounting. Also, SMT could be used as well to assemble the components correctly.

    What Are CPU PCB Ground And Ground Technique?

    PCB Ground

    The grounding in the CPU PCB or electronics means the backup path track of the electric current that facilitates an alternative to the current flow back to the ground if any fault happens to the wiring or current conducting.

    The active wire for the current flow provides the currents, and the neutral pathways safely send it back to the ground.

    PCB Grounding

    PCB Grounding

    Floating ground, virtual ground, AC ground, Earth ground, and chassis ground are the different terminologies for the grounding in the PCB or electronics. Wrong use of grounding techniques could reduce the performance of the electronics or your PCB.

    Different grounding techniques might be used for grounding a CPU PCB.  Following are among them.

    I. Ground Plane

    One of the most popular and widely utilized grounding techniques is the ground plane. This is done with a big piece of copper foil. The open regions of the PCB, which do not include any trace or component, are generally covered with copper by the CPU PCB makers.

    The ground plane should be put on the base layer of a two-layer CPU PCB, while the parts and signal pathways should be on the top layer, as indicated by ordinary PCB ground plane rules.

    II. Ground Plane Vias

    On the off chance that the CPU PCB load up has a few ground planes, the ground planes would be connected employing discrete vias in different areas on the PCB. Vias are holes in the PCB that allow you to link the two sides together. This confirms that the ground planes on the PCB may be accessed from any part of the board.

    III. Connector Grounds

    All connectors connecting the circuit on the CPU PCBs should also be connected to the grounding. You should use ground pins to isolate the connections so that all signal conducts are parallel.

    What Are The Materials Of A CPU PCB?

    There are various materials used to form a CPU PCB.

    Prepreg

    Prepreg is a light fiberglass fabric that has been dealt with and relieved with epoxy resin. The prepreg is processed to make the CPU PCB utilizing a particular prepreg treater gear.

    FR4 Epoxy Resin

    FR4 Epoxy Resin

    The prepreg that is utilized to assemble a CPU PCB incorporates FR4 epoxy sap, Teflon, and polyamide. They start as a liquid condition and afterward cold and become firm.

    Copper Clad Laminate

    Prepreg is used with a copper-clad cover, which is compacted along with high tension and warm structure. Copper-clad turns into a plastic composite in the CPU PCB when the prepreg solidifies.

    Copper Foil

    To pass current flow via the CPU PCB, copper foil is utilized to etch copper traces. The copper traces are held in place by the outer or inner layer of the PCBs.

    Solder Mask

    The thermal paste on CPU PCBs is a solder mask, which protects them from oxidation and corrosion. Because the external circuitry of the boards is left unprotected, they should be covered with thermal paste.

    Silkscreen

    Silkscreen is a kind of white ink used to recognize the areas of the CPU PCB. It shows what parts will be put in which regions on the bind veil layer utilizing white letters.

    The color of the silkscreen might be different, though.

    Surface Finish

    Surface finishes are the ultimate layer of protection for CPU PCBs against corrosion and oxidation. Surface finish coating might be used to protect copper holes and pads on PCBs. Surface finishes are applied using various metals such as gold, nickel, silver, tins, etc.

    How Do Thermal Characteristics Impact The CPU PCB?

    FR4 is the most used prepreg, which has a dense relation with the thermal characteristics. The thermal factors of the CPU PCB mainly impact the flexible material on it. See the following to check how the thermal state of the CPU PCB impacts.

    Mainly thermal properties are divided into four parts. And they separately impact the PCB.

    I. Glass Transition Temperature

    The CPU PCB substrate gets soft at a specific temperature. The substrate returns to its normal state when the temperature is removed from it. This temperature is known as the glass transition temperature (Tg).

    Glass Transition Temperature Effect On PCB Material

    Glass Transition Temperature Effect On PCB Material

    The range of the glass transition temperature should be under 200° C to 250° C.

    II. Decomposition Temperature

    The CPU PCB substrate loses 5% of its mass when exposed to the decomposition temperature (Td). Td has a permanent impact on the CPU PCB, but Tg has a transient effect. As a result, the Td range should be more than 250° C.

    III. Coefficient Of Thermal Expansion

    The expansion of the CPU PCB substrate is known as the coefficient of thermal expansion (CTE) when it goes under the Td. Usually, the CTE ranges between 10 to 20 parts per million (ppm). Up to 70 ppm is a safe expansion for the board substrate.

    IV. Thermal Conductivity

    The thermal conductivity(k) is in the form of the ability of a PCB to conduct heat through it. The higher the k-level, the better is the performance and thermal conductivity. The copper has the best thermal conductivity of 386 W/mK.

    This range is far better than the typical dielectric constant, which generally ranges 0.3 to 6 W/mK.

    What Are The Top Microcontrollers That Are Used In CPU PCB?

    The significant features of microcontrollers are they compact the size and cost of the chips by using microprocessor, memory, and input-output devices in a single place. As the performance gets raised with cost-efficiency, the use of IoT is becoming handy day by day.

    Here we show the top 5 microcontrollers that are primarily used in modern electronics.

    • 1MIPS per MHz

    Which Factors Should You Be Considering Choosing Microcontrollers?

    The size of the microcontroller, speed, power utilization, streak memory, vital peripherals, costs, and environment support is, for the most part, factors that planners consider to choose a microcontroller. Most of the current realities here are affected by design needs.

    To put it another way, the expense of a microcontroller is relative to its size. Subsequently, the planners just select as much as is required. The application’s objective dictates the fringe to utilize. Also, because speed and force productivity is often compromised, planners ought to return to their particulars.

    PIC32MX250F128B Microcontroller

    PIC32MX250F128B Microcontroller

    As far as force utilization and which peripherals and hinders are dynamic versus not dynamic, low-power modes are ideal. Regarding the size of the flash, planners should remember that as flash size increases, the pin count and the cost are also increased.

    What Is The Solder Mask And Its Functions On A CPU PCB?

    When you finish the fabrication of a CPU PCB, the copper traces on the PCB remain at risk of oxidation and corrosion. This happens due to exposure of the board to the environment. To protect the board from this type of destruction, a protecting coating is used. This coating is known as the solder mask.

    Solder mask is a liquid photo imageable layer on the top and bottom surface of the PCBs. The main jobs of the solder mask are:

    • To protect the CPU PCB from oxidation and corrosion
    • Increase the lifespan of the board
    • Creating shorts during soldering so that the solder bridge cannot be formed

    Applying Solder Mask On PCB

    Applying Solder Mask On PCB

    You will find four types of solder masks:

    1. Epoxy Liquid Solder Masks
    2. Top And Bottom Side Solder Masks
    3. Liquid Photoimageable Solder Mask
    4. Dry Film Photoimageable Solder Mask

    What Are The Types Of CPU PCB?

    Different types of CPU PCBs are made in terms of rigidity and layers.

    1. Single-Sided PCB

    The single-sided PCB is the most common CPU PCB. It is made up of a single copper conductive layer. On one side, components are inserted, while the etched traces are visible on the other.

    2. Double-Sided PCB

    The double-sided PCB has a copper layer on both sides. Vias are utilized to link the board’s metal components. Both through-hole and surface mount technologies can be used to install components on a double-sided PCB.

    3. Multilayer PCB

    A multilayer printed circuit board is made up of at least three conducting layers. Multilayer PCBs are made up of several double-sided PCBs sandwiched together.

    4. Rigid PCB

    PCBs that are rigid cannot be folded or twisted. The boards are made on a robust substrate that prevents the PCB from bending and keeps it sturdy.

    Rigid CPU PCB

    What Are Controlled Impedance And Its Importance In A CPU PCB?

    The coordination of capacitance and inductance during a high-recurrence signal is known as impedance.

    During the high-recurrence signal travel employing the copper follows, the controlled impedance guarantees impeccable recurrence. This ensures that there is no signal misfortune, bending, or recurrence debasement.

    The matching impedance is the only way to get the highest signal power. On the other hand, more caution should be exercised when it comes to high-frequency signals. Otherwise, it may be twisted and damaged. Unexpected failures also could have happened.

    Why Are Vias Used In A CPU PCB?

    Vias are the drilled holes in a multilayer PCB. They are used to join the layers of multilayer PCBs together. The connections made through the vias allow the CPU PCBs to be kept small.

    Spot copper pads on each layer of the PCB and drill an opening through them to make a by vai. Electroplating or putting copper chambers directly in the penetrated holes makes the opening conductive.

    Vias On PCB

    What Are The Design And Layout Considerations Of CPU PCB?

    To obtain a quality design and result in a quality CPU PCB, you must consider some vital facts and assemble the PCB during the procedure.

    • Select proper and quality material for the CPU PCB
    • Components selection should be authentic
    • Determine the component placing method before designing the board
    • Keep short the high-frequency traces
    • Facilitate ground plane with high-frequency signals
    • Keep separate the analog and digital circuitry
    • Try to avoid the auto-routing
    • Think about the proper coating for the board
    • Don’t drill the vias under the components
    • Keep the via hole size as small as possible

    How To Prevent Corrosion In CPU PCB?

    Corrosion is the process of oxidation on the metal of the PCB, especially on the copper, when oxygen bonds with the metal. It produces rust and causes loss of the chemical properties of the metal. CPU PCBs are made of copper and other metal, so corrosion happens to them.

    Galvanic and electrolytic corrosion are the two most common electrochemical corrosion processes. When there is an ionic contamination or electrolyte solution in two different metals, as well as an electrical contact, galvanic corrosion happens.

    Electrolytic corrosion happens when an ionic liquid or electrolytic solution contaminates nearby traces.

    Flux corrosion is another type of corrosion. Corrosion of copper traces and holes is caused by flux residue left over during soldering.

    Surface Coating On PCB

    Corrosion prevention isn’t as difficult as you would imagine. Applying a radiative protective layer to the exposed areas of copper and other metals is all it takes. Corrosion solutions include solder mask covering, epoxy lamination, and aerosol spray. Surface finishes would also be the optimum covering to keep the outside copper regions from corroding.

    Who Are The Quality CPU PCB Manufacturers?

    There is no one word saying that you could say that only one manufacturer in the world is the best. You will find several standard features on the quality CPU PCB manufacturers. Based on the quality, you could consider each one of the best.

    A good CPU PCB manufacturer would hold the following features, which could help you to recognize them.

    • They are experienced in the industry
    • They provide extraordinary customer services
    • Facilitate standard working space and use modern technology
    • Able to meet the deadline
    • Have bulk production ability at a time
    • Ensure the precise quality PCB

    You could select a manufacturer for your CPU PCB production if you get such features on them.
