What Kinds of Resistance Does Shengyi SH260 PCB Material Have?
Each prepreg system and laminate material possesses unique resistance characteristics, which are determined by their specific properties. The ability to withstand varying temperatures and heat is solely reliant on the inherent properties of the laminate. Furthermore, the materials utilized in creating these prepreg systems dictate whether the resulting PCB material can endure harsh or hazardous environmental conditions. Let us now delve into some of the resistance traits exhibited by Shengyi SH260.

Thermal Resistance
This particular prepreg system boasts a remarkable capacity for resisting heat flow across both its internal and external surfaces, making it an ideal choice for applications requiring exceptional thermal resistance. Consequently, this laminate excels in high-temperature environments due to its outstanding thermal reliability, setting it apart from other prepreg systems.
High Temperature Resistance
Shengyi SH260 is a pure polyimide with a high glass transition temperature of 250⁰C laminate and prepreg system, reinforced with a non-woven aramid substrate. Shengyi SH260 combines the high-reliability features of polyimide (improved PTH reliability and temperature stability) with the low in-plane (X,Y) expansion of 12-15 ppm/ ⁰C and outstanding dimensional stability of the aramid reinforcement.
CAF Resistance
The Shengyi SH260 PCB material can withstand the procedures for electrochemical corrosion or migration. Interestingly, this aids how long lasting this laminate material can be. This prepreg system has the ability to retain its high performance because of its CAF resistance.
Water Resistance
This is very important for all laminates and prepreg systems. Although the level at which laminates can absorb water is considerably different. This laminate is waterproof and has a low rate of water absorption.
Therefore, it has the capacity to hold water. It serves as a barrier to moisture condensation or doesn’t allow the flow of water through its components. Hence, this laminate is durable and works in diverse applications and different atmospheres.
The Advantages of Using The Shengyi SH260 PCB Material
There are many benefits that come with using this type of polyimide laminate and prepreg system. It works effectively for most applications because of its potential to resist some dangerous environmental conditions.
High Rate of Resistance
Earlier we listed the different kinds of resistance levels this laminate material has. One benefit with using Shengyi SH260 is that its resistance rate is high such that no harmful chemicals or UV light, high degrees of temperature can affect it. This is one thing to always check out for in PCB materials.
Thermal Stability
We shouldn’t forget that the ability to retain stability under high temperature is one unique feature of this laminate material. With increasing temperature, this laminate and prepreg system can still work without any hindrance.
Simple Processing Modes
When it comes to the processing modes of Shengyi SH260, it is very simple. This kind of laminate doesn’t require extra procedures for processing it. The processing modes are quicker and simpler in comparison to other PCB materials. It has faster speed when in operation in many applications or multilayer circuit boards.
Durability
This is one advantage of using this laminate and prepreg system. When it comes to high durability, this PCB material is one that gives you value for your money. This is because engineers and designers always ensure this material is compatible with lead free assembly. Thus, it can be potent for years connecting multilayers in the circuit boards.
Multiple Performance
When we talk about versatility, this is the laminate material to opt for. This is because it serves multiple purposes for different applications. That is why it is easier to use Shengyi SH260 for various applications. It is not a rigid kind of laminate and prepreg system that works only on one type of application.
What Mechanical Properties of Shengyi SH260 PCB Material?
