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:
-
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.
-
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.
-
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.
-
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.
-
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
