In printed circuit board (PCB) fabrication, a device or tool that creates an angled edge on the board’s perimeter is employed. This process, often automated, removes a small amount of material from the edge at a specific angle, typically 30 to 45 degrees. For example, after a PCB is routed from a larger panel, a specialized machine might grind the edges at a 45-degree angle to prepare it for insertion into a card edge connector.
The use of an angled edge provides several advantages. It facilitates smoother insertion into mating connectors, reducing the risk of damage to both the board and the connector’s contacts. This angled surface also minimizes the potential for scraping or catching during handling and installation. Historically, hand tools were used, but automated machinery has enhanced precision and production efficiency. The precision achieved by modern equipment ensures consistent and reliable connections.
