With the passage of time the need of being independent from the outside market has significantly increased and physics lab is approaching this goal by developing specific expertise and manufacturing skills in the lab. Moreover, making complex circuit on Vero board was time consuming and prone to error. Previously PCB manufacturing was done from Hall road or through chemical etching in the lab. Recently, the Physlab has acquired CNC based CCD PCB machine. The machine is capable of routing and drilling copper boards. The machine works on the principle of isolation milling. The workstation comprises of a dedicated personal computer with driver software and Isocam, vacuum cleaner (for sucking dust while spindle is running) and a power supply unit. We have Tungsten carbide routers of diameter 0.6 mm and drill bits of 1.2 mm, 0.5 mm, 0.3 mm and 3 mm size.
Commercial usage of the facility can also be discussed.
