Custom Made PCB Boards with Gerber File
♦ What is a Gerber File?
A Gerber file is the standard file format used in PCB (Printed Circuit Board) manufacturing to describe the physical layers of a PCB design. It contains all the necessary information for fabricating the PCB, including:
Each layer of the PCB is represented as a separate Gerber file (e.g., .gbr or .ger extension).
♦ Why Are Gerber Files Important?
✔ Universal Acceptance – Used by all PCB manufacturers worldwide.
✔ Precision – Ensures accurate reproduction of your PCB design.
✔ Manufacturing Blueprint – Tells the fab house how to produce the board.
♦ Types of Gerber Files in a PCB Design:
A complete PCB design typically includes these Gerber files:
