Industrial control includes a wide range of applications for all aspects of modern life. As long as your project is developed based on MCUs (microcontroller units) and for business, public, and industrial-grade uses, you will need industrial control PCB assembly to turn your idea into real products.

In this blog, you can see the applications of industrial control PCB assembly and project examples.

What is Industrial Control PCB Assembly?

industrial control PCB assenmbly

Industrial control has two aspects - industrial-grade and MCU-controlled.

What does an industrial grade mean? It means the device serves business uses for many people, its reliability, performance, and safety are important. By contrast, a commercial-grade device, such as a home appliance, is for home use for one or a few users.

MCU-controlled is straightforward to understand. The device is developed based on and controlled by Microcontrollers. These MCUs can be ESP32, ESP8266, Neoway wireless modules, Quectel WiF and Bluetooth modules, Fibocom IoT wireless communication modules, and Simcom automotive-grade wireless communication modules.

So we can define industrial control now -- it is an industrial-grade device developed based on and controlled by MCUs for public and business uses.

PCB assembly for industrial control requires precision and high reliability. It includes PCB fabrication, component sourcing, PCB assembly, and value-added services such as IC burn-in programming and box-build assembly. As industrial control PCB assembly will finally go to mass production, it is necessary to have PCBA prototyping and sampling before mass production.

PCBONLINE is an industrial control PCB assembly manufacturer providing free DFM (design for manufacturing) and one-stop PCBA manufacturing. You can work with PCBONLINE to turn your industrial control project into successful real products.

Now, you know the applications of industrial control PCB assembly. However, the above applications are just the projects we have manufactured for our clients. The applications are way more. As long as your project is developed based on an MCU or MCUs, and it is used for public, government, production, and industrial-grade uses, you will need industrial control PCB assembly from PCBONLINE to bring your design or idea into reality.

Project Examples of Industrial Control PCB Assembly

Industrial control PCB assembly requires high reliability, and any issues may happen during the PCBA process. How do you ensure your industrial control project can lead to success? You will need a professional PCBA manufacturer like PCBONLINE to offer DFM and solve technical and unexpected issues throughout the process.

Below, you can see industrial control PCB assembly projects and how we solve the issues for our clients during the electronic manufacturing process.

Industrial inverter PCB assembly

industrial inverter PCB assembly

This high-power industrial inverter board requires a large area of PTH (through-hole) assembly. It requires high soldering fullness, solder-intake amount, and overall thermal dissipation, demanding much experience and technical capabilities to complete the industrial inverter PCB assembly process. PCBONLINE has rich experience in industrial inverters and electric vehicle charging pile PCBAs. We specifically pay attention to jig/fixture design, soldering oven temperature control, and manufacturing process design.

During PTH assembly, the through-hole components may float, as shown in the figure below, leading to gaps and uneven surfaces between components and the PCB. This common issue arises from improper manual component placement and the thermal expansion of solder paste during wave soldering. How does PCBONLINE solve it?

PTH assembly floatation issue

Well, our solution is straightforward:

First, when designing the fixture for wave soldering, we ensure it not only protects components from high temperatures but also presses down on components prone to movement to prevent displacement during reflow.

Secondly, for components requiring high positional accuracy (such as buttons and sockets that must align precisely with the enclosure), we apply a layer of adhesive to the component's bottom before wave soldering, which can effectively mitigate deformation.

Besides, selective soldering is good for preventing PTH soldering defects and component displacement, albeit with lower production efficiency and higher costs.

Industrial camera PCB assembly

This is an industrial camera PCB assembly project for road detection. PCBONLINE provides turnkey ODM PCB assembly for our client, including software and hardware development and one-sop manufacturing. The industrial camera PCBA is used for road traffic detection and municipal monitoring features:

  • 4K High-definition cameras,
  • Face recognition function,
  • Autofocus

PCBONLINE not only develops and manufactures the PCBAs but also designs the enclosure and assembles them to be the final products. Besides, we conducted an application simulation test by putting the industrial camera beside the road for two weeks and recording the data.
