Shengyi PCB materials have been existing for a while now. These materials provide an effective solution to PCB fabrication issues. With the advancement in technology, there is a high need for high performance PCBs. With the right material a high performance and high end PCB can be fabricated.

Also, the properties of a PCB material will determine its performance. Therefore, it is important to use the right PCB material for fabricating your boards. In this article, we will be discussing the Shengyi 1600 PCB material and its properties.

What is Shengyi S1600?

Shengyi S1600 is a conventional FR4 PCB material. This laminate features great properties like great tracking resistance and UV blocking. It functions as the base material for a printed circuit board. This PCB base material is ideal for fabricating high end PCBs. Also, this board features properties like high tensile strength and high temperature resistance.

Features of Shengyi S1600

Shengyi 1600 has got great features which include:

UV blocking

This conventional FR-4 PCB material is great at blocking UV rays from the PCB. Therefore, it protects a circuit board from the impact of UV rays.

Great tracking resistance

The comparative tracking index (CTI) of Shengyi S1600 PCB material is ≥ 600V. CTI describes the leakage current resistance of base material of a PCB.  The CTI value specifies Shengyi S1600 resistance against ecological impacts like moisture. Also, this value evaluates the proportionate resistance of Shengyi S1600.

Good PCB Processability

Shengyi S1600 PCB material features great PCB processability. Also, this means that this base material is ideal for PCB manufacturing.

The Mechanical and Thermal Properties of Shengyi S1600

Shengyi S1600 has great thermal and mechanical properties. Each of these properties contributes to the performance of ShengyiS1600.

Low glass transition temperature (tg)

The glass transition temperature of Shengyi S1600 is 135 degree Celsius. This means that at 135 degree Celsius, the temperature of Shengyi S1600 will transform from hard to soft. A PCB base material with this Tg value provides great insulation and low water absorption rate.

Coefficient of thermal expansion (CTE)

The coefficient of thermal expansion measures the changes in the size of a material in response to varying temperature. The CTE (Z axis) of Shengyi S1600 is 55 ppm/℃ before glass transition temperature. After Tg, the CTE is 308 ppm/℃.

Decomposition temperature (Td)

Td describes the temperature at which Shengyi S1600 decomposes chemically. The Td of Shengyi S1600 is 310 degree Celsius at 5% weight loss. When a material goes beyond its Td value, changes to its properties are irreversible.

Thermal stress

This refers to mechanical stress caused by temperature change of a material. This helps to create a relative ability of PCBs to withstand the thermal excursions related to rework and assembly. Also, the thermal stress of Shengyi S1600 is >100S at 288 degree Celsius.

Flexural strength

This describes the ability of a PCB material to resist breakage during bending stress. Also, it specifies how Shengyi S1600 resist bending deflection during energy application to the PCB. Therefore, the flexural strength of Shengyi S1600 is 550 MPa.

Peel strength

This evaluates the adhesive strength of materials bonded together. Also, it describes the ability of Shengyi S1600 to resist forces that can peel it apart. The peel strength of Shengyi S1600 is 1.8 N/mm after thermal stress at 288 degree Celsius.

Benefits of Shengyi S1600

Shengyi S1600 provides several benefits. Due to the benefits, this laminate is widely used in PCB fabrication. Below are the benefits of Shengyi S1600
