These properties serve as evidence of the laminate’s compliance with the Shengyi S1141 specifications. The following are the main properties that should be tested for Shengyi S1141 laminates:

1. Glass Transition Temperature:

The glass transition temperature of Shengyi S1141 laminates should be tested under designated treatment conditions, such as Differential Scanning Calorimetry (DSC), yielding a result of 140 degrees Celsius. This indicates the temperature at which the material transitions from a solid glass state.

2. Flammability:

To determine the flammability characteristics of Shengyi S1141 laminates, testing should be conducted to identify the ignition point. Understanding the flame limits is essential for safely operating these laminates.

3. Current Resistivity:

Testing should be performed to determine the point at which current leakage occurs for Shengyi S1141 laminates. Both volume resistivity and surface resistivity should be assessed after subjecting the laminates to moisture resistance.

4. Dielectric Factors:

The dielectric constants and dielectric breakdown strength of Shengyi S1141 laminates should also be tested. These tests assess the laminate’s electrical behavior and its ability to withstand electric currents without failure.

5. Thermal Stress:

Evaluating the thermal stress of Shengyi S1141 laminates, both when etched and unetched, is crucial. The absence of delamination within 60 seconds confirms the use of Shengyi S1141 laminates.

6. Peel Strength:

What Factors do You Consider when Selecting Shengyi S1141 Prepreg Materials?

When selecting Shengyi S1141 prepreg materials, there are many factors to consider, given that these materials are often used in the manufacturing of printed circuit boards (PCBs). Here are some key considerations:

Thermal Performance: Shengyi S1141 prepregs are typically selected for their high thermal performance. The glass transition temperature (Tg), decomposition temperature (Td), and coefficient of thermal expansion (CTE) are all important parameters to consider. The higher the Td and Tg, the better the material can withstand high temperatures.

Dielectric Constant (Dk) and Loss Tangent (Df): The Dk is a measure of the electrical insulating properties of the material, and the Df indicates the loss of energy in the form of heat. These properties are crucial for the signal integrity and speed of a PCB, especially in high-frequency applications.

Mechanical Properties: The prepreg material should have suitable mechanical properties, such as tensile strength, peel strength, and flexural strength. These properties determine the material’s ability to withstand various forms of stress during PCB manufacturing and assembly.

Flammability Rating: The flammability rating (typically UL 94V-0 for PCB materials) is an important safety consideration. This rating indicates the material’s ability to extinguish flame once the source of the flame is removed.

Moisture Absorption: The lower the moisture absorption, the better. Moisture can degrade the PCB’s performance and reliability, particularly at high frequencies.

Processability: The prepreg should be compatible with standard PCB manufacturing processes, such as lamination, drilling, and plating.

Cost: Finally, the cost of the material is always a consideration. While higher performance materials are often more expensive, they may be necessary for certain high-reliability or high-frequency applications.

Remember to always consult with your PCB manufacturer or material supplier to ensure that the selected prepreg material meets all the requirements of your specific application.

What information is needed when purchasing Shengyi S1141 laminates?

When communicating with a Shengyi S1141 laminate manufacturer, it is essential to provide specific information to ensure accurate understanding of your requirements. Here are the key details you should convey:


Clearly specify the desired thickness of the Shengyi S1141 laminate. This measurement should be provided in millimeters, as it determines the overall thickness of the laminate material.

Copper Foil:

Provide detailed information regarding the size of the copper foil you require for your Shengyi S1141 laminates. This specification is crucial as it determines the thickness and conductivity of the copper layer. The value for copper foil size should be expressed in micrometers, as it represents a small percentage of the laminate’s composition.

Standard Size:

Specify the desired standard size for your Shengyi S1141 laminates. Since these laminates are typically small in size, it is important to provide the dimensions in millimeters. Clearly communicate the required length and width of the laminates to ensure accurate manufacturing and compatibility with your intended application.

By communicating these specific details in a clear and professional manner, you can enable the Shengyi S1141 laminate manufacturer to better understand your requirements and produce laminates that meet your specifications.
