Make PCB by yourself Printed Circuit Boards (PCBs) are typically made from a fiberglass epoxy resin substrate with copper foil on one or both sides. More affordable PCBs use a phenolic resin substrate, commonly found in household electrical devices. PCB design is facilitated by software like Eagle, allowing for the quick creation of a circuit pattern. The process involves printing the design on transparent paper, transferring it to a photo-resist PCB using ultraviolet light exposure, and developing the design using a developer solution. The board is then etched with a ferric chloride solution to remove excess copper, leaving the desired copper traces intact. Finally, holes are drilled in the board using a CNC machine or manual tools to complete the PCB, making it a cost-effective and efficient method for DIY electronic projects.
