Product Description

 
Custom 8B35 Polycarbonate Lexan PCB Board Designer For Lighthouse Device
 
 

Here's a detailed description of using Lexan (polycarbonate) as the material for a PCB (Printed Circuit Board):

Lexan PCB Board Overview:
Lexan, a type of polycarbonate plastic, is an alternative material to the more commonly used FR-4 (fiberglass-reinforced epoxy) for manufacturing PCB boards. Lexan offers several distinct advantages that make it a suitable choice for specific applications.

Key Features and Benefits:

1. Durability and Impact Resistance:

   • Lexan is known for its exceptional impact and shatter resistance, making it highly durable and able to withstand physical stress or accidental impacts.
   • This property makes Lexan PCBs well-suited for industrial, military, or other rugged applications where the board may be subjected to harsh environments or potential drops.

2. Thermal Resistance:

   • Lexan has a relatively high continuous-use temperature range, typically around 120°C to 135°C, making it suitable for applications where the PCB may be exposed to elevated temperatures.
   • This thermal resistance can be beneficial for PCBs that generate substantial heat during operation, though additional cooling solutions may be required due to Lexan's lower thermal conductivity compared to FR-4.

3. Electrical Insulation:

   • Lexan exhibits excellent dielectric properties, providing effective electrical insulation for the copper traces and components on the PCB.
   • This helps to prevent short circuits and maintain the overall electrical integrity of the circuit.

4. Transparency and Aesthetics:

   • The transparent nature of Lexan can be advantageous in applications where visibility of the PCB components is desirable, such as for prototyping, testing, or diagnostic purposes.
   • This transparency can also contribute to a unique and visually appealing design for the PCB.

5. Chemical Resistance:

   • Lexan demonstrates good resistance to a wide range of chemicals, including acids, bases, and solvents, making it suitable for applications where the PCB may be exposed to various chemical agents or cleaning solutions
