Sculptured Finger
The Sculptured Finger PCB is a specialized interconnect solution designed for applications that require integrated, durable contact fingers as part of the PCB itself. Using precision etching and forming techniques, the copper fingers extend beyond the edge of the board, eliminating the need for separate connectors and simplifying assembly.
Key Features of Sculptured Finger PCB
- Integrated Contact Fingers: Sculptured copper fingers are built into the PCB, providing a rugged, low-profile connector interface.
- Durable Copper Construction: Formed from thick copper layers (up to 4 oz) for high current-carrying capability and extended wear life.
- Low-Profile Design: Eliminates bulky edge connectors, reducing overall assembly size and cost.
- Plating Options: Hard Gold, ENIG, ENEPIG, or selective plating available to maximize wear resistance and conductivity.
- Custom Configurations: Fingers can be sculpted to various lengths, thicknesses, and profiles to meet unique application requirements.
- IPC Class 3 Compliance: Manufactured to meet the most stringent reliability standards.
