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 productdesign.
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.

FR-4 material ultra long board PCB
2-layer transparent FR-4 material ultra long ultra-thin PCB
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 scenario
s.
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 environ
ments.
Flame retardancy: As a flame-retardant material, FR-4 has flame-retardant properties and can self extinguish when bu
rned, 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 require
ments, 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 multil
ayer PCBs, which requires ensuring tight bonding between layers to avoid problems such as bubbles and stress conc
entration. 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, sol
derability, 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 achie
ving 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 devi
ces 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 mu
lti-layer PCB can provide more creativity for product design, showcase the technological and exquisite sense of the p
roduct, 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.

| FAQ | |||||||||||||||||||
| Serial Number | Question Point | Answer | |||||||||||||||||
| Q1 | Q: What information is required to make a PCB | CEGSATE: Gberber files for PCB production, product process instructions, such as material requirements, surface treatment requirements, finished product thickness requirements, PCB stack structure diagram for advanced products, copper thickness requirements for each layer, sample quantity requirements, batch order requirements, product application fields, and other related information are required | |||||||||||||||||
| Q2 | Q: What information does PCBA need to provide | CEGSATE: BOM report is required (including the brand, specifications, and model of the components), X and Y coordinate numbers of PCBA components, and processing requirements: Do we need to purchase the components on our behalf? Or customer supplied components? Do you need software burning? What is the required quantity? What is the monthly demand and other detailed information. | |||||||||||||||||
| Q3 | Question: Is my file secure? | CEGSATE: Your files are very secure, and we protect intellectual property rights for our clients throughout the entire process. All files provided by the customer will never be shared with any third party. | |||||||||||||||||
| Q4 | Q: What is the minimum order quantity? | CESGATE: We do not have a minimum order quantity for PO orders. We are able to handle small and large batches flexibly. | |||||||||||||||||
| Q5 | Q: What is your inspection method? How do you control the quality? | CESGATE: In order to ensure the quality of PCB, FPC, and PCBA products, we use flying pin testing for small batches, which is usually used for samples and small batches; The inner circuit undergoes 100% optical inspection through AOI, and we have online AOI automatic inspection for intermediate inspection. Batch finished products undergo 100% inspection through E-SET testing rack. The appearance is 100% inspected by fully automated finished product testing equipment and FQC. PCBA undergoes automatic optical inspection (AOI), 100% X-ray inspection of BGA parts, and first article inspection (FAI). PCBA products that require software burning must undergo 100% comprehensive testing on the finished product testing rack according to product functional requirements before they can be shipped. |
|||||||||||||||||
| Q6 | Q: What standard should PCB be shipped according to? | WCESGATE: e accept and store according to the international IPC-6012 Level 2 standard.
