A depaneling router is a machine similar to wood router. It uses a router bit to mill the material of the PCB. The hardness of the PCB material wears down the bit, which must be replaced periodically. Routing requires that single boards are connected using tabs in a panel. The bit mills the whole material of the tab.
The earliest types of EDA routers were "manual routers"—the drafter clicked a mouse on the endpoint of each line segment of each net. Modern PCB design software typically provides "interactive routers"—the drafter selects a pad and clicks a few places to give the EDA tool an idea of where to go, and the EDA tool tries to place wires as ...
Specctra is a commercial PCB auto-router originally developed by John F. Cooper and David Chyan of Cooper & Chyan Technology, Inc. (CCT) in 1989. [2] The company and product were taken over by Cadence Design Systems in May 1997. [3] [2] [4] Since its integration into Cadence's Allegro PCB Editor, the name of the router is Allegro PCB Router ...
A computer numerical control (CNC) router is a computer-controlled cutting machine which typically mounts a hand-held router as a spindle which is used for cutting various materials, such as wood, composites, metals, plastics, glass, and foams.
TopoR (Topological Router) [nb 1] is an EDA program developed and maintained by the Russian company Eremex. It is dedicated to laying out a printed circuit board (PCB). The current version is 6.3.17875 as of 2017-09-20.
A PCB milling system is similar to a miniature and highly accurate NC milling table. For machine control, positioning information and machine control commands are sent from the controlling software via a serial port or parallel port connection to the milling machine's on-board controller. The controller is then responsible for driving and ...
The name Excellon format is derived from the company Excellon Automation (not to be confused with Excellon Software), which was the market leader in PCB drilling and routing machines during the 1980s, and whose proprietary format became widely used. There are actually two Excellon formats, the older Excellon 1 and Excellon 2.
In contrast to an IC layout, where the entire finished layout is stored in one graphics file, different files and formats are needed for PCB manufacture. The fabrication data consists of a set of Gerber files, a drill file, and a pick-and-place file containing the location and alignment of the devices generated for automated placement of the ...
