    Mobile PCB: The Ultimate FAQ Guide

    Mobile phones are a revolutionary invention of the modern telecommunication system. The tiny compact mobile set can be possible only for the development of Mobile PCB. Also, they are improving day by day and offer more and more features and services.

    PCBMay have been manufacturing all kinds of mobile circuit boards, maintaining the highest quality, and ensuring customer satisfaction.

    What Is A Mobile PCB?

    Mobile PCB is a small circuit board that is designed for analog-to-digital and digital-to-analog conversion of mobile phones. A Mobile PCB board is constructed by the combination of necessary computer chips.

    So that they can convert the analog audio signal into a digital signal. Again, they change the converted digital signal of mobile phones into analog.

    Mobile PCB

    Mobile PCB

    How Mobile PCBs Are Made?

    Like other circuit boards, Mobile PCBs are constructed by Printed Circuit Boards materials such as copper is conductive material with polytetrafluoroethylene, fiberglass reinforced epoxy.

    Several steps have been done for making printed circuit boards for mobile. Here are the steps-

    Step 1 – Circuit Design

    First, make the blueprint of the circuit design along with a mobile charger diagram. For this, use software and trance-wide calculators.

    Step 2 – Print The Diagram

    The next step is to print out the circuit diagram using a plotted printer. That print copy will show the details about Mobile PCB layers and components. Clear ink means non-conductive areas where the inked part shows the conductive copper trances.

    Step 3 – Construct The Structure

    In this part, the physical construction starts. The substrate carries the necessary components of the circuit structure. They are formed through oven heat to be secured. Copper layers are etched in this step.

    Step 4 – Components Alignment

    After alignment of the tracks and components of inner and outer layers, now time to laminate under UV rays. The board needs to be washed in an alkaline solution to clean the excess photoresist. Also, remove the unwanted copper.

    Step 5 – Layer Interconnection

    Then the clean layers are inspected. The holes are drilled in this step that creates a connection to inner and outer layers.

    Mobile Circuit Board Etching

    Mobile Circuit Board Etching

    Step 6 – Fusing

    Now the board forms a shape by fusing. After that, the laminating process begins. Then the prepreg layer goes under the substrate, copper foil, and PCB resin. After that, the copper layer is applied. Pins are punched on the layers to press them together.

    Step 7 – Plating

    After that, they are ready for plating. The fused layers are passed through a chemical solution. These will create a cote panel with thin copper conductive layers.

    Step 8 – Planting

    Now it’s time to plant the mobile circuit board. A thin tin guard is applied to the circuit. That will protect the inner copper layers.

    Step 9 – Apply Solder Mask

    After plating and planting, again eating is processed. Then apply an epoxy solder mask film on the circuit board.

    Step 10 – Place SilkScreen

    One of the crucial steps is silkscreen the circuit. The critical and essential lines are placed on the board. After that, coated with a soldering coat finish to enhance the quality of the circuit

    How Does A Mobile PCB Work?

    The mobile phone PCB is considered the brain of the smartphone. This circuit operated the entire functionalities and operations. Not a single component works behind the functionalities. Several components work combined in the mobile circuit diagram. Have a look-

    Computer Chips

    We already mentioned the mobile phone PCB diagram is designed with few computer chips. The role of computer chips is to convert the analog-to-digital signal and vice versa.

    When analog audio signals go from an analog device, they convert the signals into digital.

    Again, do the opposite conversion that is from digital to analog.

    Moreover, the digital signal processor of the mobile circuit board did both compression and decompression of audio signals. And you may wonder, the capacity is 40MIPS. Which can continuously convert 40 Million instructions per seconds signals analog to digital and digital to analog every second.

    Computer Chips

    Computer Chips

    Flash Memory and ROM Chips

    In mobile circuit boards, flash memory and ROM chips are placed for the storage location of smartphones. The capacity varies from device to device and also can be customized.

    Again, the radio frequency and power sections are served for the power management and mobile phone charging system. Though the flash memory and ROM chips are absent in the mobile charger PCB diagram. These both control and operate various FM channels where RF amplifiers help the signal go in and out of the antennae.

    Microprocessor

    The other crucial element of Mobile PCB that works for mainly consumers. The microprocessor(CPU) operates and checks mobile tasks which are performed by the keyboard and display area. Also, deal with the control signals as well as command operations. So that, user can easily understand and use the keyboard’s functionalities.

    How Many Layers Are Used To Construct Mobile PCB?

    Mobile PCBs are usually multilayers that may contain 2 or more laminating conductive layers. The number of layers depends on the device requirements. To construct a smartphone PCB diagram, up to 12 layers can be used.

    Now you may ask why single layers are not used in smartphones? Well, single-layer PCBs are useful for simple applications. To integrate with complex applications, multi-layer printed circuit boards are suitable. They have enough capabilities to deal with and fulfill the requirements of the application.

    Multilayer Printed Circuit Board

    Multilayer Printed Circuit Board

    Besides providing several noteworthy benefits that single PCBs don’t. For example, mobile circuit boards are more flexible, smaller in size, and light-weighted. Also, they are capable of operating functions as well as increase the performance of the overall mobile.

    What Are The Advantages Of Mobile PCB?

    The advantages of Mobile PCB can’t be described in one word. Here are the key benefits of mobile circuit boards-

    1. For using a multilayer circuit, increase the functionalities and capabilities
    2. The Mobile PCB is very small compared to other devices’ circuits. It’s more compact and lightweight
    3. Provides higher mechanical strength so that the performance won’t degrade
    4. Halogen-free Dupont layered Mobile PCBs are environment friendly.
    5. Ensures higher reliability to satisfy consumers

    What Are The Requirements For Designing Mobile PCBs?

    Designing the mobile circuit especially the android Mobile PCB diagram is challenging initially. Now it’s not too hard if you know the requirements. PCBMay offers customization in the designing of mobile circuit boards. The main requirements of designing Mobile PCB are as follows-

    Multilayer PCB Fabrication

    Laminating the multilayer PCB is the 1st requirement. During manufacturing time The multilayer circuit board for mobile phones is fabricated by a subtractive process. Layers are in between 2 to 12 and they are interconnected by the laminations, electroless copper, copper plating, and mechanical drilling.

    And then time to fabricate the solder mask. The colors are different for different purposes like green, orange, etc. With a solder mask, solder coating and silkscreen are placed on the circuit board.

    Use BUM Technology

    During the subtractive process for double layer or multilayer circuit boards, the lead finish is applied as an insulating dielectric on both chemical plating and electrical plating through the holes. This is called BUM technology for manufacturing Mobile PCB. This process is repeatedly run until the circuit layer lamination is fully finished.

    Smartphones require small and thin circuit board diagrams. BUM technology makes the PCB thin with higher density. Also keeps the trace space and width lower. For IC-grade high-density packaging, this efficient method is used.

    Place Fiducial Marks

    Another must-have requirement is the mobile phone PCBs have at least 2 fiducial marks. In phone circuits, the spaces are placed very carefully to arrange flexibility.

    The diameter should be 1mm contrasting between the environment and solder mask materials color. If the estate is limited, the solder mask size could be customized as 0.5 mm.

    In addition, the fiducial marks should have the same background to make them compatible with copper coating.

    Fiducial Marks Of Mobile PCB

    Fiducial Marks Of Mobile PCB

    Design The Panel

    After these, the final requirement is designing the panel of the Mobile PCB. The panel may be double-sided on long slit hole panels.

    • Double-Side V-Groove Panel

    A double-side v-groove panel is more suitable for designing Mobile PCB at a lower cost. Or need to repair them after breaking up. This method works like the neat margin for Mobile circuit boards. The technique is to apply 30 degrees with ⅓ or ¼ of the total circuit thickness. If the ICs with BGA or QFN packages are installed in the device, this method is not appropriate for the application.

    • Long-Slot Hole Plus Circular Hole

    If the Mobile PCB has more than 4 layers then the LCD board, SIM, and TF cardboard button boards are fabricated by this technique. The Long-slot hole plus circular holes are applied according to the daughterboard’s shape and figure and applied to the irregular or arc shape.

    With the development of the properties of smartphones like miniaturization, multifunctions, intelligence, reliability, etc this method is useful and efficient.

    What Problem Comes When Mobile PCBs Tracks Are Broken?

    Printed circuit boards have copper conductor lines which are known as PCB traces or tracks. They are the conductive path to pass signals through the circuit board surface. When electricity passes through tracks, a significant amount of heat is produced.

    This is one of the reasons for tracks being broken or burnt. Some other factors like excess pressure, Improper component spacing, lightning strikes, severe power surges or shorts, dirt, and carelessness are also responsible for line disconnecting of PCB.

    When a track is broken, it affects the functionalities of the Mobile PCB. Sometimes, breaking tracks can stop the total operations of mobile phones.

    How Do We Know The Mobile PCB Track Is Broken?

    If the mobile phone is not working properly, the common problem behind it is the broken track of the internal circuit boards. There are some other reasons like Chemical Leakage, Electromagnetic Issues, Missing Solder Mask Between Pads, or even defeat in the mobile charger PCB diagram that can cause the malfunction of the device.

    Even the broken tracks are not visible to the naked eyes. Then what is the way to know if the Mobile PCB track is broken or not?

    Well, the “Line Checking” method is used in the telecommunication industry to find out the broken tracks. The mobile circuit board should have 7 to 10 layers for this checking system. For this technique, the following tools will be needed-

    • Analog/Digital multimeter
    • Desoldering station
    • Soldering gun
    • Magnifying glass

    Copper Tracks Of Mobile Circuit

    Copper Tracks Of Mobile Circuit

    The steps of Line checking are as follows-

    Step 1 – Visual Inspection

    Start with a Visual Inspection, find out anywhere the Mobile PCB board is getting burnt or melted.

    Step 2 – Power Module Checking

    Then check the power module. For this, you need to check the input and output voltage regulator to give the regular value or not.

    Step 3 – I/O Ports Checking

    Next step is to check the Input/Output Ports. The damage in I/O ports is also the reason for the malfunction of the mobile phone.

    Step 4 – Communication Ports Checking

    Check the Communication Ports whether the lines are connected properly or not.

    By checking these modules, you will find out whether the PCB tracks are broken or not. If you find the lines are separated for burning, melting, or other reasons, immediately repair them.

    Our company PCBMay provides great services for only manufacturing PCB boards but also repairing them effectively.

    Is There Any Difference Between Mobile PCB And Telephone PCB?

    Besides, the Mobile PCB is compact, thin, repairable, and consists of more layers than The Mobile PCB and telephone PCB have differences. The mobile works by radio frequency where the telephone is operated by cable.

    So the arrangement and placement of components, their properties, number of tracks, layers, fabrication processes are quite different for them.

    In telephone printed circuit boards, there is a metal disk known as the diaphragm. That converts the sound waves into electrical energy. This electrical energy goes through the telephone cables and is again converted into sound waves, Which can be heard by the receiver person.

    On the other hand, the printed circuit board of a mobile has computer chips. This circuit board is also regarded as a mini-computer for its features and capabilities. Which are higher than the telephone circuit.

    Mobile circuit boards convert the audio analog and audio signal into digital. The digital signals pass as radio waves that can catch another mobile. The receiver mobile circuit is converted into an analog signal again, And people can hear it then.

    What Is The Highest Heat Resistance Capacity Of A Mobile PCB?

    Mobile PCBs are high-temperature PCBs, they have to work for multiple functions. The Mobile PCB is constructed by polyimide flex laminate systems though it has the capacity level. The highest temperature withstanding capacity is 150 degrees Fahrenheit.

    More temperature may cause melting and breaking the tracks of the internal circuit. So far, the mobile will not work properly, the keyboard and screen fail to interact. Again the solder melting point temperature is around 360 to 370 degrees Fahrenheit. Thus low temperature is useful for operating the mobile properly.

    Several components and materials are used for fabricating Mobile PCBs under heat and pressure. You should keep yourself protected and maintain some safety standards.

    That will prevent the possibility of illness or any other diseases for the conduct of PCB materials.

    Washing hands

    Some ingredients are harmful to your skin. It’s better to practice using hand gloves when preparing and storing circuit boards. If somehow you did these without gloves, wash your hands properly after the laminating process.

    Safety Equipment

    During the manufacturing of Mobile PCB, high radiation can happen. You should wear safety glasses, an apron and hand gloves. These save you from direct conduct of sharp edges of metal, heat, and chemicals.

    Room ventilation

    The room or fabrication place should have a proper ventilation facility keeping sufficient temperature. Any dark, gloomy room may hamper the manufacturing process of Mobile PCB.

    Is It Possible To Custom Laminate On Mobile PCB?

    Mobile PCBs are multilayer circuits, so custom laminates can be done on them. Usually, mobile circuit laminates are made by Polyimide for their mechanical, thermal, chemical, and electrical properties.

    If your application is needed, you can customize the laminate type, materials, thickness, components, thermal properties as well. Also change the finish like Glossy, matte, metallic, solid color, textures, etc based on the device requirements.
