Detailed Introduction to Transparent FR-4 Multilayer PCB

Material characteristics

High transparency: Using special transparent FR-4 material, the transparency can reach 85% -92%, which can clearly display the internal circuit layout and component arrangement, bringing unique visual effects to product design.

Good electrical performance: Similar to ordinary FR-4 material, it has excellent electrical insulation performance, which can effectively prevent current leakage and electromagnetic interference, ensuring stable operation of PCB in complex electrical environments.

High mechanical strength: The glass fiber reinforced epoxy resin laminated board endows the transparent FR-4 multi-layer PCB with good mechanical strength, enabling it to withstand certain external impacts and vibrations, and is not easily deformed or damaged, making it suitable for various application scenarios.

Heat resistance: The heat resistance temperature range is usually between 130 ℃ and 180 ℃, which can maintain the stability of its structure and performance in higher temperature environments and adapt to different working environments.

Flame retardancy: As a flame-retardant material, FR-4 has flame-retardant properties and can self extinguish when burned, improving the safety of PCB use and complying with relevant safety standards 2.

manufacturing process

High precision etching: Through high-precision exposure and etching processes, the transparent conductive layer is precisely processed to ensure that the line width and spacing accuracy of the circuit pattern meet the design requirements, usually up to 3/3mil or even smaller, ensuring the accuracy and consistency of the circuit.

Laminated process: Advanced laminating technology is one of the key steps in manufacturing transparent FR-4 multilayer PCBs, which requires ensuring tight bonding between layers to avoid problems such as bubbles and stress concentration. At the same time, it is required that the alignment error between layers be less than 10 μ m to ensure the performance and reliability of the multilayer board.

Surface treatment: According to different application requirements, various surface treatment methods are provided, such as OSP (organic solder mask), gold deposition, tin spraying, etc., which can improve the oxidation resistance, solderability, and wear resistance of the circuit board surface.

Application Area 1

Intelligent display: such as transparent display screens, smart glass, etc. The transparent FR-4 multi-layer PCB provides a transparent circuit solution for display devices, making the display effect more unique and beautiful, while also achieving higher integration and functionality.

Automotive electronics: Used for intelligent instrument panels, head up displays, and other components in cars, which can enhance the driving experience and bring more innovative space to car interior design, making the electronic devices in the car more integrated with the overall interior style.

High end consumer electronics: In products such as smartphones, tablets, wearable devices, etc., transparent FR-4 multi-layer PCB can provide more creativity for product design, showcase the technological and exquisite sense of the product, and meet consumers' needs for personalization and aesthetics.

Medical equipment: In the fields of medical imaging equipment, medical monitoring instruments, etc., transparent PCBs can provide clearer image transmission and signal processing, which helps doctors to diagnose and treat more accurately, and also facilitates equipment maintenance and repair.
