How to Choose the Right PCB Assembly Manufacturer for High-Volume IoT Products in Asia
Choosing the right PCB assembly manufacturer for your IoT product is a critical decision. If you’re like Shelly USA, with innovative products for automating homes and buildings, you need a supplier who can handle high-volume production and deliver quality at scale. Whether you’re working on smart thermostats or other home automation devices, this guide will help you find the ideal PCB supplier in Asia that meets your specific needs.
Why Asia is the Leader in PCB Manufacturing for IoT Products
Asia, particularly China, Taiwan, and Southeast Asia, has long been the global hub for PCB manufacturing. With decades of expertise, state-of-the-art technology, and an unmatched capacity to handle both high-volume runs and custom designs, Asia is the go-to destination for companies looking to scale their IoT products. Whether you’re producing high-frequency PCBs for smart devices or rigid-flex boards for wearables, these regions have the infrastructure to support it all.
If you’re developing a smart home product like Shelly’s Thermostatic Radiator Valve head, you need a partner who can deliver reliable PCBs with short lead times. Let’s take a look at the top manufacturers and key factors to consider when selecting the right supplier for your IoT needs.
Who’s the Largest PCB Manufacturer for IoT Products?
When it comes to sheer production capacity, China leads the charge. Manufacturers like Viasion, JLCPCB, and PCBWay are industry giants, offering everything from cost-effective prototype runs to high-quality mass production. But Taiwan also has its fair share of reputable manufacturers, including Compeq Manufacturing and Unimicron, who specialize in rigid-flex and HDI (high-density interconnect) PCBs ideal for cutting-edge IoT products.
Whether you need cost-efficiency or high-precision boards for smart home devices, these manufacturers can scale with your product’s needs.

Taiwan is especially known for quality control, which is vital for products like Shelly’s smart thermostats that must operate reliably in residential environments.
How to Choose Between PCB Manufacturers in Asia?
There are several important factors when deciding which PCB manufacturer in Asia to work with. Here’s how to make the best choice:
- Price vs. Quality: If cost is your primary concern, China may offer the most affordable options. But if you’re after high-quality, Taiwan offers top-tier precision and reliability for IoT devices.
- Lead Time: If getting your product to market quickly is crucial, consider JLCPCB or Viasion, who offer fast turnaround times.
- Customization: Ensure that the manufacturer can handle custom designs, especially if you’re working on unique IoT solutions like smart home devices.
Can I Scale Up Production with Asian PCB Manufacturers?
Absolutely! Most PCB manufacturers in Asia can handle both low-volume prototypes and high-volume production. Whether your IoT product is in the prototype stage or ready for mass production, there’s a manufacturer who can scale with you.
Shelly USA, for example, likely needs a supplier who can handle both small batch production for initial product testing and high-volume runs as the product gains traction in the market. Many manufacturers have systems in place to handle both needs without compromising quality.
How to Ensure High-Quality PCB Assembly for IoT Devices
Here are some tips to ensure your PCB assembly meets the high standards of IoT devices:
- Prototype First: Before going into mass production, request samples or a pilot batch to test for quality and functionality.
- Request DFM (Design for Manufacturing) Analysis: This helps avoid potential production issues and ensures your design can be efficiently manufactured.
- Test for Reliability: Make sure the manufacturer provides in-circuit testing (ICT) and electrical testing to ensure your PCB works flawlessly in real-world conditions.
