Features of PCB2100: 1. High efficiency: It just need few minutes to make a piece of PCB. 2. Accuracy: The min error of digital-display-control drill hole < 1mil (0.025mm). 3. Automatical: After operation data input through software, you just press the keys on operation system to make PCB Boards. CNC operation: Input PROTEL. PCB file into machine drive program_DK, plate making, drill hole, cutting will be finished automatically. Under PC control, the drive motors of X, Y, Z-axes drive main shaft motor to move according to program order. The main shaft motor drives the cutter to make the PCB into the shape that the user requires. Mechanical action can be executed strictly according to program order. PCB making technology is physical engraving technique. Without the process from wet to dry and from cold to hot on chemical PCB manufacture, copper clings on PCB board strongly. Clear PCB line: You can see whether there is connection or break on PCB by your eyes. Moreover, the software is easy to operate.
