Automotive PCB

What is an automotive PCB?

As we all know, an automotive circuit boards is a complex circuit system that controls most of the electronic operations of a car. It is a circuit board specifically designed for various automotive applications, ranging from ignition systems and navigation systems to headlights.

At the same time, car pcb need to withstand the high vibrations, extreme temperatures, and corrosion from various chemicals in the automotive environment, so they must be manufactured according to the highest standards, such as the widely recognized IPC Level 3 standard.

Why choose KING FIELD 's automotive PCB services?

KING FIELD is a PCB manufacturer whose products and services cover multiple fields, including automotive PCBs. Our automotive PCB services offer the following advantages:

• Experience and scale

Since its establishment in 2017, KING FIELD has accumulated rich experience in PCB manufacturing. We currently have a research and development team of 50+ people and a production team of 300+ people. We are committed to providing customers with one-stop solutions from solution design to mass production delivery.

• Quality assurance :

1. In terms of quality control, KING FIELD has passed six major system certifications: IATF 16949, ISO 13485, ISO 9001, ISO 14001, ISO 45001, and QC 080000. With 7 SPI, 7 AOI, and 1 X-Ray testing equipment throughout the process, we use a digital MES system for full traceability to ensure that every PCB is of consistent quality.
2. Automotive-grade reliability testing : high and low temperature cycling (-40°C to 125°C), vibration testing, and damp heat aging testing to ensure stable operation of the product in complex automotive environments.
3. The entire process of quality control is closed-loop : incoming material inspection, pre-engineering review, full production inspection, outgoing re-inspection, and report archiving. Each process is traceable, and the defect rate is controlled at the ppm level.

• Diverse partners :

KING​‍​‌‍​‍‌​‍​‌‍​‍‌ FIELD works with prestigious brands such as PRETTL, Yadea, Xinri, and Schneider in Germany, consistently reinforcing its position as a benchmark in the ODM/OEM PCBA intelligent manufacturing industry with high-performance, cost-effective solutions.

l After-sales guarantee

• We are one of the very few companies in the industry to provide "1-year warranty + lifetime technical consultation" service. If the product has a quality problem not caused by human factor, it can be returned or exchanged without charge and the relevant logistics costs will be borne by ​‍​‌‍​‍‌​‍​‌‍​‍‌us.

Q1. What are the differences between automotive PCBs and ordinary PCBs?

KING FIELD: Automotive circuit boards are designed to meet industry standards for high reliability, high temperature resistance, and vibration resistance, which ordinary PCBs cannot withstand in the specific environmental conditions of automobiles.

Q2. What are the advantages of using automotive PCBs?

KING FIELD: Using automotive PCBs offers the following advantages:

1. Improve performance
2. Enhanced reliability

Q3. What do you think is the most fundamental challenge facing automotive PCBs in terms of reliability and lifespan?
KING FIELD : The most fundamental challenge is to ensure that the PCB remains fully functional in extreme environments throughout the entire lifespan of the vehicle (usually more than 15 years) .

Q4. What are the special requirements for the materials used in your automotive PCBs?

KING FIELD : Our automotive PCB materials must use high-performance substrates to improve heat resistance and stability, and we must also adopt stricter process control to ensure the overall safety of the vehicle .

Q5. What are the mandatory requirements for traceability and consistency of PCBs in the automotive industry?
KING FIELD : KING FIELD's MES system enables full-chain traceability of information for each PCB or production batch, from raw materials, production process, process parameters to final testing data .
