PCB Routing
PCB routing is a manufacturing process used to cut, separate, or contour printed circuit boards using controlled routing paths. In electronics production, routing is applied to create defined board outlines, internal cutouts, or separation lines within a PCB panel. This glossary explains the key terms and system concepts related to PCB routing in a clear and structured way.
As a specialist in laser technologies and industrial laser systems for the photovoltaics, electronics, and semiconductor industries, the Photonics Systems Group develops application-specific solutions for demanding PCB manufacturing processes.
PCB Routing Process
The PCB routing process defines how material is removed along a predefined path to shape or separate printed circuit boards. Routing can be used for both full separation and partial contouring, depending on the board design and production stage.
In modern electronics manufacturing, routing is often combined with laser-based processing to achieve high accuracy, clean edges, and consistent results across complex PCB layouts. This process is also called tab cutting, where the router creates breakout tabs that are subsequently removed by a laser to completely separate the individual PCB from the panel. For industrial implementation, Photonics provides dedicated laser routing solutions designed for precision electronics applications.
PCB Router
A PCB router is a system used to execute routing paths on printed circuit boards. Traditionally, PCB routers relied on mechanical tools or router bits, whereas laser-based PCB routers enable contactless processing and higher design flexibility.
PCB Router Machine
A PCB router machine integrates the routing technology, motion control, and process software into a single production platform. In laser-based systems, the routing path is executed using a focused laser beam, allowing precise contours without mechanical stress on the board.
PCB Laser Router Machine
A PCB laser router machine is a specialized routing system that uses laser technology to cut and contour printed circuit boards. Compared to mechanical routing, laser PCB routing offers advantages such as contactless laser material processing, high contour accuracy, and small radii.
Photonics develops laser routing machines for PCB and microelectronics applications based on its DR20/30 machine series. These systems are designed for laser drilling and routing, combining precise motion control, stable beam delivery, and application-specific process configurations.
Laser Types used in PCB Routing Machines
Depending on the material stack-up and application requirements, laser routing systems may use different laser sources. In PCB manufacturing, green USP lasers and UV lasers are commonly applied to achieve precise material removal with controlled thermal input.
