Definition of Shengyi SAR10S
Shengyi SAR10S is a type of PCB (Printed Circuit Board) material manufactured by Shengyi Technology Co., Ltd. SAR10S is a high-frequency laminate material designed for applications that require excellent electrical performance at high frequencies. It is commonly used in the telecommunications, aerospace, and automotive industries.
Properties Features of Shengyi SAR10S
Low glass transition temperature (Tg):
The glass transition temperature (Tg) is a critical property that influences the thermal performance of a PCB material. It represents the temperature at which the material transitions from a solid state to a rubber-like state. In the case of Shengyi SAR10S PCB material, the Tg is measured at 140 degrees Celsius. This low Tg indicates that the material can effectively withstand high temperatures without compromising its structural integrity.
Low coefficient of thermal expansion:
The coefficient of thermal expansion (CTE) is a measure of how much a material expands or contracts in response to changes in temperature. Shengyi SAR10S PCB material exhibits a low CTE of 27 ppm/℃ before reaching its Tg, which increases slightly to 30 ppm/℃ after reaching Tg. This low CTE implies that the material experiences minimal dimensional changes when exposed to elevated temperatures. Consequently, Shengyi SAR10S is an ideal choice for high-end PCB applications where dimensional stability is crucial.
Excellent thermal conductivity:
Thermal conductivity is a vital property that determines the efficiency of heat transfer in a PCB material. Shengyi SAR10S possesses an impressive thermal conductivity of 1.1 W/mK, indicating its ability to effectively dissipate heat. This high thermal conductivity enables the material to efficiently absorb and transfer heat from its surroundings. As a result, Shengyi SAR10S is highly suitable for applications that require optimal thermal management.
High decomposition temperature (Td):
The decomposition temperature (Td) of Shengyi SAR10S is measured at 410 degrees Celsius with 5% weight loss. Td signifies the temperature at which the material chemically decomposes. It is desirable for PCB materials to have a Td exceeding 320 degrees Celsius. Shengyi SAR10S surpasses this requirement, demonstrating its capability to withstand high temperatures and maintain its structural integrity. PCB materials with high Td values also tend to possess elevated glass flow temperatures.
High comparative tracking index (CTI):
The comparative tracking index (CTI) is a crucial parameter that evaluates the insulating material’s ability to withstand unwanted current flow between circuit board traces. Shengyi SAR10S PCB material exhibits an exceptionally high CTI, emphasizing its superior tracking resistance capabilities. The CTI value directly influences the overall performance and reliability of a PCB. By possessing a high CTI, Shengyi SAR10S ensures enhanced electrical insulation and reduced risk of electrical breakdown.

Suitability for LED Devices: Shengyi SAR10S PCB material is particularly well-suited for use in LED TVs and LED lighting due to its exceptional dielectric properties. These properties enable efficient electrical insulation, ensuring reliable performance and longevity in LED applications.
Overall, Shengyi SAR10S PCB material offers a range of benefits, including its halogen-free composition, excellent thermal performance, and suitability for LED devices. These advantages make it a preferred choice for high-quality PCB fabrication, particularly in applications that require reliable thermal management and electrical insulation.
Guide of Using Shengyi SAR10S PCB Laminates
When working with laminates such as Shengyi SAR10S, it is crucial to take certain precautions to ensure the integrity and quality of the material. Here are some important guidelines to follow:
1. Wear protective gloves when handling the laminate to prevent copper foil collisions and avoid contamination of the copper foil surface by bare hands.
2. During operation, carefully inspect the laminate for any scratches or pollution that could affect its performance. Any damage or contamination should be addressed before proceeding.
3. Pay special attention to the drilling and cutting processes to avoid any breaks or damage to the laminate. These steps require precision and care to maintain the integrity of the material.
4. When working with aluminum boards, consider the unique properties of this material. Ensure proper insulation barriers between conductors and the board’s edge. Maintain a minimum distance of 2mm between the line and the edge, and at least 3mm between the hole and the line.
5. Due to the metal structure of aluminum laminates, traditional baking methods can be replaced with mechanical leveling techniques if warpage is detected.
6. It is important to use harder cutting tools when working with aluminum laminates. Special milling tools and V-CUT blades should be employed. Additionally, reducing the cutting speed can help ensure clean and precise cuts.
By adhering to these guidelines in a professional manner, the handling and processing of laminates like Shengyi SAR10S can be done effectively, reducing the risk of damage or contamination and ensuring high-quality PCB fabrication.
Drilling and Punching Process of Shengyi SAR10S
The drilling and punching processes for Shengyi SAR10S involve creating holes and openings in the laminate material for various purposes such as component mounting and interconnection. Here is an overview of these processes:
1. Drilling Process:
a. Drill Bit Selection: Choose the appropriate drill bits based on the hole size requirements specified in the PCB design. The drill bits should be made of high-speed steel or carbide to ensure durability.
b. Drill Tool Setup: Set up the drilling machine by securing the laminate material firmly on the machine’s work table. Ensure proper alignment and fixation to prevent any movement during drilling.
