Automotive
As automotive electronics continue to evolve over the past decades, major car manufacturers have been adopting more and more intelligent and energy-efficient designs to meet market trends and consumer demands. Back in the 1980s, automotive electronics accounted for about 2-3% of the entire vehicle. Nowadays, automotive electronics take up more than 50% of a vehicle. Automobiles are expected to become smarter, safer and more energy efficient, all thanks to the automotive electronic systems.
As automobiles become increasingly electrified, automotive products are required to be even more reliable compared to general consumer products. Automotive products are designed and manufactured to be used in relatively harsh environments. For example, automotive products must pass a reliability test of over 500 hours at a high temperature of 155 degrees Celsius and a low temperature of -40 degrees Celsius. In addition, car manufacturers require these products to last at least 10 to 15 years, which is a relatively high standard.
Automotive PCBs carry the crucial components to ensure the proper functioning of a vehicle's electronic systems. These systems encompass a wide range of functionalities, including engine control, transmission, braking, safety features, infotainment systems, and advanced driver-assistance systems (ADAS). PCBs provide the necessary interconnections and pathways for electrical signals to flow smoothly between these components, enabling them to communicate and operate effectively.
Automotive PCB Manufacturer in Taiwan
Having worked with well-known automobile manufacturers in developing and manufacturing automotive over the years, Liang Dar is extremely experienced in manufacturing automotive PCBs. From the early design and development phase to the flexible mass production phase, the company works closely with its customers to develop the market.
Automotive Dashboard Display Module
Primarily composed of single-sided, double-sided, 4-layer and 6-layer boards. From mechanical gauge dashboards to LED dashboards, in recent years, multifunctional dashboard screens that can display different information are on the rise.
In-Vehicle Infotainment System Module
Mainly consists of double-sided to 6-layer boards. Due to automotive modular integration, similar to a laptop, the system requires higher-end ICs. Therefore, blind and buried vias and resin plugging are widely used.
Automotive Battery Module
Automotive Battery Module System (BMS) PCB on a double-sided or multi-layer FR4 structure, laminated aluminium sheets are used as heat sinks, which directly help to dissipate the heat of high voltage or high brightness LED lights.
Electric Power Window Switches
Mainly made with double-sided boards. Gold-plated PAD and carbon paste printing are usually used for the switches.
Automotive LED Module
Primarily consists of single-sided, double-sided, 4-layer and metal core boards. Vehicle lighting controllers and headlight level controllers are mostly made with single-sided or double-sided boards. 4-layer boards are more often used in applications that integrate LEDs and their driver controls. Metal core boards are mostly used for high/low beams, daytime running lights, or occasions that require high-brightness LEDs.
Remote Keys
Automotive Control Knobs
Mainly made with single-sided and double-sided boards. Abrasion-resistant thick hard gold plating or resistive carbon paste is also used to control the knob position.
Tire Pressure Monitoring System
Made primarily with double-sided and 4-layer boards. As the system is used inside the tire where the temperature is higher and there is shock and vibration, the substrate should be even more reliable and durable.
