CNC machine

Are you a start up in the electronics industry? Tired of turn around times for the PCBs from the manufacturing houses? Thinking of doing a PCB prototypes by yourselves with a small setup? Thinking that fabricating a PCB using chemicals can be a messy job? Then CNC machine must be one of your choices.

               CNC short form for computer numerical control. These types of machines work automatically as per the instructions provided by the user. The manual techniques used in high production environments are long one and are replaced by CNC machines. Consider the PCB fabrication process where milling is done to create the signal routing patterns. PCB drilling, routing and engraving are done using CNC machines which can bring the prototypes out quickly and at a very low cost if done in-house. The CNC machine comprises of the mini computer or the microcomputer that acts as the controller unit of the machine. The existing CNC machines involve inputting a PCB Gerber where in the complete PCB process will be automatically done through a single machine. The entire process can be monitored over a well-defined GUI. The options when using a CNC machine is used involves checking of PCB material to be etched, drill bit to be used on the machine, the PCB tools (in fact output of PCB tools) supported by the CNC machine. the drill depth can be automated in the tool. The drill position is controlled through a well calibrated motors which meant no chance of any error. The RPM of the machine can be up to 110,000. Copper clad board is used instead of photo-resistant board. Here we are eliminating hazardous chemicals during the process. The process with CNC machine might be slow than normal etching but is always a quality and better environmental friendly option.
