Industrial PCBA – Circuit boards for industrial control machines

In the past, much of the work in factories was done by hand. This mode of production not only reduced industry efficiency but also caused physical and mental exhaustion for workers. Fortunately, those days are long gone, and now we invest heavily in machinery and equipment for industry. These high-end machines can accurately complete various complex processes in a short amount of time.

To enable engineers to produce factory equipment that meets various performance requirements, the demands for industrial PCB manufacturing are increasingly stringent. Many people think that a circuit board is just a circuit board, and that there is no difference in how it runs programs and operates in different environments. However, this is clearly wrong.

An industrial PCBA, also known as an industrial control board, is a circuit board designed to withstand shock, vibration, extreme temperatures, humidity, and dust in industrial equipment. This PCBA is used to perform many operations in the industrial control industry. It is designed to configure the circuit of a project in a compact manner, which allows current to flow accurately in the required path and enhances product operation. These boards are also critical components of industrial control projects and equipment, helping to measure and configure numerous parameters of the assembly line, and obtain accurate physical quantities.

Turnkey Project

The complexity of consumer electronics PCBA cannot be compared to that of industrial control machinery. Therefore, we recommend that customers opt for turnkey solutions for their complex projects. With a turnkey supplier, you can rely on them to handle everything from the prototyping stage of the industrial control board to final production, testing, and delivery. These manufacturers also have a complete feedback system that can provide you with details of your projects from start to endpoint. Ensure that the project creation and management process is the easy and straight word and that the manufacturer has details responses related to any query.

Quick Turnaround

Manufacturers that offer fast turnaround PCB assembly services are becoming increasingly important in the development of the industrial control board industry. This is especially crucial for industries that experience rapid technological advancements or frequent design changes. Manufacturers with fast turnaround capabilities can respond to customer needs more quickly and gain insight into market trends.

In large-scale industries, time is money. The longer it takes to complete a project, the more expensive it becomes to construct. Therefore, it is advisable to choose a supplier who can manufacture PCBs in shorter time intervals, whenever possible.

Experienced​

Having extensive manufacturing experience is crucial when selecting a PCB manufacturer. It is also beneficial for the manufacturer to have completed similar projects in the past, in addition to a strong background in PCBA manufacturing. FS Technology is a company that meets these requirements. With over 10 years of experience in PCBA processing and expertise in industrial control board projects, including power supply units, robotics, electronic switch gears, industrial drives and inverters, electronic test and measurement equipment, energy control systems, and industrial smart meters, our team is well-equipped to handle various industrial projects.

Cheap Price

Industrial PCBs can often be expensive due to various factors, such as design complexity, number of layers, and materials used. To mitigate the cost overhead, it may be sensible to choose Chinese manufacturers who can often produce PCBs with lower labor and material costs. However, it is important to note that while cost is a crucial factor to consider, it should not come at the expense of quality. It is crucial to find a manufacturer with the capabilities to produce industrial PCBs that are both cost-effective and high-quality.

Quality Assurance

The issue of poor quality industrial control circuit boards is absolutely intolerable. When these boards are used in industrial equipment, any errors can result in significant losses for the customer, including costs associated with downtime. As such, PCBA manufacturers must implement strict quality management practices, which goes beyond simple PCB inspection and involves many other factors.

A Comprehensive Guide to Industrial Control PCBs

Industrial Control PCB Board Definition​

Industrial control boards are specific circuit boards used for industrial control operations. They are different from commercial off-the-shelf boards as they are created according to specific requirements. These boards have general-purpose inputs and outputs (IO) that can be used to connect peripheral devices such as valves, motors, and sensors.

There are also dedicated industrial control PCB designed for specific operations, such as temperature control boards. These boards have inputs connected to a thermocouple and outputs connected to heating contractors, which control the heat of devices and environments.

Industrial control boards are made of two materials: a non-conductive base and copper traces and pads. The copper traces and pads serve as interconnections between components assembled on the PCB board. These boards can be single layer, double layer, or multilayer PCB, depending on the complexity of the operations. For single-layer boards, there are copper traces on only one side, while for two-layer boards, traces are on both sides.

These boards are also known as universal PCB as they have programming features that allow users to set the functions according to their requirements. A programming logic controller (PLC) is an example of a general industrial control board. It operates by writing different programs and compiling inputs to perform various operations. It has digital input, analog input ports, and high-speed counter ports that provide communication operations.

Industrial PCB Design Factors

Component Layout

The placement of components on the board layout is a critical factor to consider when designing industrial control PCB boards. Improper component placement can affect the reliability and performance of the final product. During PCB board design, special care must be taken to ensure that components are installed on the board with a minimum of 100 mils space between the edges of the board and the mounted components. This ensures that the dimensions of the board and mounted holes are consistent. 

EMI & RFI

In industrial applications, it is crucial to minimize the effects of Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), which can cause noise and disrupt the operation of the PCBA. To this end, FS Technology offers several strategies:

Board layout: To reduce the risk of noise coupling, separate high-frequency circuits from low-frequency circuits and keep signal traces away from power and ground planes. Signal traces should be as short as possible, while power and ground planes should be as large as possible and routed with low inductance hole connections to minimize the impedance of the power network.

Filtering components: Add filtering components such as capacitors and inductors to power and signal lines to filter out unwanted noise.

Grounding and Shielding Techniques: Enclose sensitive components in Faraday cages to block EMI and RFI.

Component Selection: Choose circuit board components with high-quality grounding and shielding. Use shielded cables to connect the board to external devices to prevent unwanted signal coupling.

Industrial Control PCB Material

The selection of materials for PCB manufacturing is critical and should be based on the specific working environment. Materials for PCBs used in industry must be able to withstand harsh conditions, such as high temperature, high voltage, humidity, vibration, and chemical exposure. Some commonly used materials for industrial PCBs are:

  • Polyimide: This high-performance material can withstand extreme temperatures up to 400°C and is often used in aerospace, military, and high-temperature industrial control applications.
  • Ceramic: A ceramic PCB is made of a ceramic substrate and metal traces. They have excellent thermal conductivity and can handle high temperatures and harsh chemicals. They are commonly used in power electronics and high-frequency applications.
  • PTFE: PTFE or polytetrafluoroethylene is a fluoropolymer with excellent electrical insulating properties that can withstand high temperatures up to 260°C. It is commonly used in high-frequency and microwave applications, as well as harsh chemical environments.
  • FR-4: This composite material made of woven fiberglass cloth and epoxy resin is the most commonly used material for general PCBs, including industrial. FR4 PCB has good electrical insulation properties and can withstand high temperatures and chemicals.
