How to Choose a Reliable Automotive PCB Manufacturer

Automotive PCBs are widely used in various electronic systems in automobiles, from ADAS and vehicle lighting to infotainment and powertrain components. According to PR Newswire, the global automotive PCB market is expected to reach $12 billion by 2026 due to the growing demand for new energy vehicles and the need for more in-car entertainment and safety features.  Nowadays, there are countless automotive PCB manufacturers in the world trying to share the benefits of this market, but unlike other PCBs, automotive PCBs must be fabricated with extremely high reliability and stability, so you need to consider carefully when choosing an automotive PCB manufacturer. In this article, we will detail some important considerations and provide a list of quality automotive PCB suppliers for your reference. Now let’s dive right in…

Key Considerations When Choosing an Automotive PCB Manufacturer

Key Considerations When Choosing an Automotive PCB Manufacturer

I. Products

The first thing we need to consider is the product. We need to know what kind of PCBs the automotive PCB manufacturer can provide or what kind of PCBs they really specialize in. For example, commonly used automotive PCBs are HDI PCBs, high-frequency PCBs, metal core PCBs, and flex-rigid PCBs, then you should check if they can provide all these printed circuit boards and see if they have rich experience in manufacturing such PCBs.

Then, we should check the quality of the circuit board by asking if they have stringent quality control processes and certifications like ISO9001, TS16949, ISO14001, UL, etc, which can demonstrate their commitment to quality control.

Price is another important factor need to be considered in term of products. It’s true that quality always comes first, but the cost can never be ignored. Before working with an automotive PCB manufacturer, we can ask if there is any discount for high-volume orders or any support for return customers. For each quotation, please confirm whether there are any additional charges. In a nutshell, you should find a manufacturer who can provide you with the exact products you want with high quality and reasonable prices.

II. Industry

Different industries have different standards and requirements for printed circuit boards. For example, PCBs used in consumer electronics such as smartphones tend to be designed in smaller sizes, while PCBs used in the automotive industry require high reliability to withstand extreme conditions. Therefore, it is very important to know which industries a PCB manufacturer is good at, it is less likely that a PCB manufacturer specializes in all industries, in general, they are proficient in a specific industry. So, if you have any automotive PCB project, your best bet is to find an automotive PCB manufacturer who is experienced and well versed in all the requirements and standards of the automotive industry.

III. Automotive PCB Manufacturing Capacities

Another key consideration is the capacities that an automotive manufacturer has. We need to ensure that they are capable of providing high-quality PCBs and following the project timeline. Below listed some key points that we should figure out:

  • Facilities

Collecting information about the facilities of an automotive manufacturer helps us to make decisions significantly, which affects the production capabilities and turnaround time. In addition, we should also ask about the location of facilities, which is related to the shipping time and shipping costs. For example, MOKO Technology is located in Shenzhen, adjacent to Hongkong. As one of the largest export trade cities in China, it has a transportation system extending in all directions. Products can be delivered to the world at the fastest speed whether they are by ship or by air.

On the other hand, asking manufacturers about the equipment they use or going to their production site. Such information tells us their production efficiency and the order volumes they can handle. Generally speaking, those manufacturers who use state-of-the-art equipment are more likely to produce higher quality products.

  • Technologies

It is also very important to understand the technology that the automotive PCB manufacturer is referencing, we need to make sure that their technology can meet the requirements of the project. For a product with high requirements such as automotive PCB, there are high requirements for the supplier’s technology, and the leading technology in the industry must be used to ensure the high quality and high stability of the product.

  • Turnaround time

Before working with an automotive PCB manufacturer, we should understand how long it takes them to deliver PCBs, from prototypes, low-volume orders to high-volume orders, and everything in between. This ensures that their turnaround time meets our requirements and catches up with the project. Meanwhile, we can ask if there is any order tracking system available that allows us to check the order status in real-time.

VI. Services Provided

Last, we need to ask what services the automotive PCB manufacturer can offer. Some manufacturers only provide manufacturing services, and some can provide turnkey services. MOKO offers one-stop automotive PCB services ranging from designing, components procurement, prototyping, and PCB manufacturing& assembly, to inspection, and supply chain management, saving the trouble of switching between different manufacturers at different stages. In addition, ask if they provide customer support services or technical support. Many companies provide 24/7 online service, making sure that all your problems can be solved as fast as possible.
