    Frequently Asked Questions

    A sensor PCB is a circuit board used in various types of sensors.

    Copper, glass-fibre reinforced epoxy and polyimide laminates are commonly used in sensor circuit boards.

    There are three basic types of sensor PCB.
    Analog sensor PCBs
    Digital sensor PCBs
    Mixed Signal sensor PCBs

    The sensor devices or components on sensor PCBs detect changes in physical parameters, such as light, temperature, pressure and sound. Sensor circuit boards use electrical signals to convert data from the sensors into digital form for further processing or output.

    Increased precision
    Reduced size and weight
    Increased efficiency
    Improved reliability

    There are many types of sensors used in PCB. The following are some examples.
    temperature sensors
    pressure sensors
    flow sensors
    light sensors
    position/motion sensors
    current/voltage sensors
    optical sensors

    The following are the main steps to assemble the sensor circuit board by SMT.
    Step 1: Adding solder paste
    Step 2: Placing components
    Step 3: Reflow soldering
    Step 4: Wave Soldering
    Step 5: Cleaning
    Step 6: Testing
    Step 7: Packaging & shipping

    We should consider these factors, including the form factor of the sensor, the sensor’s size, the sensor’s purpose, the sensor, the electrical characteristics of the sensor, etc.

    There are many kinds of components used in sense PCBs, including resistors, capacitors, diodes, transistors, inductors, switches, connectors and integrated circuits used in sensor circuit boards.

    To better specify control impedance on sensor PCBs, we should consider the following factors:
    The sensor PCB material: Different sensor PCB materials have different electrical properties, which can affect the control impedance of the sensor system.
    The power supply design: Designing a stable and efficient sensor power supply will help to ensure reliable control impedance.
    The grounding scheme: A sensor system must be appropriately grounded to maintain control impedance consistency and reliability.
    The sensor drive circuit: To achieve the control impedance for optimal performance, we should pay attention to the sensor drive circuit.

    The following are the main steps of sensor PCB manufacturing and assembly.

    Board cutting → Drilling → Copper etching → Solder mask → silkscreen printing → Surface treatment → Profiling → Testing → Quality checking → Components assembly → Functional testing

    Thermal imaging is the most common method for monitoring the heat on sensor circuit boards. Thermal imaging involves using a camera to measure infrared radiation from an object. After that, we can calculate the object’s surface temperature through infrared radiation.

    The process of mounting sensors on PCB is rather complicated. The first step in mounting PCB sensors is determining where the sensor should be placed. Additionally, PCB designers must consider how the placement of a sensor will affect their PCB’s overall design and performance. What’s more, SMT is a common way of mounting sensors on PCB.

    A specialized drill bit is the best way to drill vias in a sensor PCB. Both mechanical and laser drill methods can be used. 

    The testing methods performed on sensor circuit boards are as follows.
    Electrical Test For Open & Short Circuit
    Automated Optical Inspection For Defects
    Testing Fixture Testing
    Functional Testing

    The following points can guide arranging the stack up on a sensor PCB.
    First, consider the sensor requirements for the application.
    Then, select the appropriate materials for the sensor PCB stack up after sensor requirements are determined.
    Finally, optimizing the sensor stack-up is crucial to ensuring that any gaps between layers are minimized.

    Although sensor PCBs have many advantages, they also have some limitations. The following are some of the main limitations of sensor circuit boards.
    Limited range
    Requirements on the sufficient power supply
    How cost
    Vulnerability
