Simply put, an S1150G is one of the laminates that a customer can opt for in their desired applications; it is produced by one of the famous companies in China, Shengyi Technology.

Almost all technical people in this industry know laminate’s importance in various applications since they are responsible for maintaining the layers glued all together.

In this article, we will share our knowledge about S1150G as one of the leading and experienced manufacturers in the industry. All of the information shared will be related to its definition, features, applications, properties, parameters, and other technical details.

At the end of this article, we anticipate that the reader will be equipped with adequate information relating to S1150G that will eventually help them in their decision-making process.

Introduction to S1150G

Introduction to S1150G

What is S1150G?

As mentioned, S1150G is a kind of laminate produced by the famous company in China, Shengyi Technology, that is recognized to be composed of Halogen-Free components.

In addition, it has a TD value of 325°C up to 365°C and a TG value of approximately 140°C to 150°C at a frequency rate of 0 to 0.1 GHz. Based on its TG value, it is regarded that an S1150G falls under the Mid-TG category. If one’s application requires a laminate that can tolerate higher than the TG value of an S1150G, this isn’t the right option for that usage.

Apart from being free from the presence of halogen, it doesn’t possess toxic substances and hazardous residues. Furthermore, the S1150G laminate is well-known for its lead-free, mechanical process compatibility and exceptional thermal resistance. Thus, making this laminate RoHS compliant and other environment-related certifications.

It can be applied in various applications and different board types; we’ll share some of the boards that are compatible with this laminate. We have lead-free, halogen-free smartphones, Xbox, automotive, and laptop circuit boards.

Nevertheless, the board class doesn’t solely include the mentioned ones; it can also be integrated into other panels. We suggest contacting an experienced manufacturer like PCBTok for quicker assistance and professional opinion.

Hot Pressing Cycle and Storage Condition of S1150G

In order to fully understand the principle and functionality of an S1150G, we will share its hot-pressing cycle procedure and the storage condition of S1150G depending on the months it is desired to store since it may vary from time to time. Thus, it is essential to have adequate knowledge of it to avoid unnecessary events to the laminate and its device.

Hot Pressing Cycle

  • The Multilayer PCB’s composition or the underlying copper influences the pace of heat-up.
  • Its treatment is roughly 45 minutes or more from 180°C to 190°C.
  • If you require deeper in-depth insights, please contact us; we have qualified and seasoned professionals ready to address your questions.

Hot Pressing the Laminate

Storage Condition

  • Three (3) months if kept at temperatures below 23°C and humidity levels below 50%.
  • While six (6) months if kept at or below 5°C. At least 4 hours should pass for stabilization prior to application.
  • Keep things protected in damp-proof cloth at all times, and be wary of wetness since the prepreg might absorb moisture while being maintained routinely, reducing the adhesion properties.
  • Stay out of direct sunlight and UV radiation.
