Computer control for PCB driller using DT-51 microcontroller interface

---

The purpose of this project is to design a simple automated machine for drilling a printed circuit board (PCB) blank at a minimum cost and with the minimum amount of conventional machinery. Drill data is transferred to the DT-51 microcontroller from a grid form generated by a visual basic program running on a PC. The printed circuit board blank is mounted to on X-Y positioning table that is constructed from a mechanism of two 460 X 480 mm which can accommodate the PCB in a 90mm X 100mm dimension. Separated from the table is a driller consisting of a high speed DC motor and pneumatic system that manipulate the driller to move up and down. The main controller is a DT-51 microcontroller. This device interfaces with the personal computer via the serial port and receives data about the hole positions. Then, the DT-51 microcontroller sends the data to each SPC Stepper motor and electro pneumatic driller. The driller software is written in visual basic that gives the input point to assembler. However, with the appropriate commands, the machine can be used for machining circuit traces also resulting in a complete PCB prototyping system.
