Automotive PCBs

Most automotive innovations, automobile and truck manufacturing require highly durable, reliable and robust PCB applications. High-tech PCB requirements signify that they can withstand harsh driving conditions and can become a catalyst for new innovations that expose automotive electronics. High-power copper-plated PCBs are the most widely used PCBs by car manufacturers. In addition, automotive PCB prototypes and PCB automotive sensors are the main sources of electronic development, especially engine management systems (EMS), instrument panels, fuel regulators, power supplies and V2V communications. Flexible PCBs and other automotive electronic circuits are the main time trend for highly compact and multifunctional technology applications in vehicles. The so-called smart car has very advanced functions and sounds futuristic, but it is unique. Other automotive PCB board applications include DC/AC power converters, digital displays, audio and video equipment, anti-lock braking systems, electronic computer units (ECU), automatic dimming and electronic mirror control systems, indoor LED lighting, power relays , Engine timing system and remote diagnosis system.

Aluminum PCB also named as metal clad (MCPCB) PCB, insulated metal substrate (IMS or IMPCB) PCB, thermally conductive PCBs, etc. It is generally including single layer, double layer and multi-layer. Aluminum PCBs is the most common type - the base material consists of aluminum core with standard FR4. Aluminum PCBs is regarded as the solution to high power and tight tolerance applications.
• Environmentally Friendly: Aluminum is non-toxic and recyclable. Manufacturing with aluminum is also conducive to conserving energy due to its ease of assembly.
• Heat dissipation: High temperatures can cause severe damage to electronics; Aluminum can actually transfer heat away from vital components, thus minimizing the harmful effect it could have on the circuit board.
• Higher durability: Aluminum provides strength and durability to a product that ceramic or fiberglass bases cannot.
• Lightweight: Aluminum is a surprisingly lightweight metal. Aluminum adds strength and resilience without adding on any additional weight.

Thick copper PCB is characterized by structures with copper thicknesses from 105 to 400 µm. These PCBs are used for high current outputs and optimization of thermal management. The thick copper allows large PCB-cross-sections for high current loads and encourages heat dissipation. The most common designs are multilayer or double-sided. With this PCB technology it is also possible to combine fine layout structures on the outer layers and thick copper layers in the inner layers. Thick copper PCB has the best elongation performance and can be used in hot melt welding methods such as oxygen blowing at a high melting point and not brittle at low temperatures. Even in extremely corrosive atmospheric environments, copper PCB forms a strong, non-toxic passivation protective layer. The application of thick copper PCB makes the core component of electronic equipment products-circuit boards have a longer service life, and at the same time it is very helpful to the size reduction of electronic equipment.

Rigid-flex PCB circuit is a hybrid construction flex circuit combining rigid and flexible substrates which are laminated together under a single structure. Each layer of rigid-flex circuit are electrically interconnected by plated through holes (PTH), which is different from a flexible circuit with FR4/PI stiffener on top or bottom of flex circuit only by the means of preventive or thermal sensitive adhesive only, no PTH. Rigid-flex board own the advantages both rigid FR4 PCBs and flexible PCBs. In rigid area, components will be soldered on, and whole board can be bendable at the flexible circuit area. as these boards are designed in a 3D space, which also offers greater spatial efficiency. Benefits of Rigid-Flex PCBs are below:
• Save space and weight by applying 3D and remove connectors
• Assure higher reliability with fewer solder joints
• Simplified assembly and test processes.
• Provide simple modular interfaces to the system environment.
• Adapt to more complexity of mechanical designs

LED PCB The LED is soldered to the circuit board and features a chip that produces the light when electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. LED will generate more heat compared with other electronic parts, which required the PCB to have a better ability for dissipating heat. For these special requirements, metal core PCB are frequently used on LED PCB, especially aluminum core PCB. This is because the aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional rigid PCB.
