           Printed circuit boards used in every modern-day   electronics   application.   For   production   standard  boards.  all aspects of board construction  are  carried  out  by machine.  based   on  a   design   created   in   a  computer   aided design package.   But this   type  of  construction   is only cheap   for   boards   which   are  to be  produced in   large quantities.  One   of   the   tasks  involved  in   this   process  is drilling all  of the  holes in  the board. which are  required to hold the  components. In   the  production  level process,  this task carried out using a drilling  device. known as a CNC (Computerized   Controlled)   machine.  which drills  holes    based  on  the  input  from.   an  NC  (Numerical Control) drilling i.e. created by the CAD application. 
 
      The   aim   of  the   paper  is  to  introduce  a  prototype drilling   machine.   which   takes   its   input   from   imaging sensor   (camera).  The   machine  drill  holes   at  the   correct points on  a printed  circuit board. based on the  input from  the   computer.  which   use   image   processing   techniques   to detect  exact   hole   location   on   sample   PCB. and  direct   the microcontroller to move the motors to the desired location.

 

         With   the   advancement   of   computer technologies.   electronic   machinery   is   being   automated, which   need   less   time   and   less   men-power.   For   this purpose,   we  have  designed  and   built   an  automatic  PCB drilling  machine.  Creating  holes   on  single.   or  multilayer printed   circuit   boards   (PCBs)   is   an   important   stage   in electronic production. Holes of different sizes and at a large  number  of positions (up to thousands). must drilled with high precision for manual. or automatic insertion of various  electronic devices and components. The PCB pattern of the circuit schematic  diagram is.  extracted from a sample PCB using image processing  techniques.  and   stepper  motors used   to  move  drill  to   the   required   position.   

       The   image processing techniques discussed in this paper.   between  used   CNC  CAD based machines  and  our  designed   machine.  will   illustrate the  importance   of  its  role  in  the   PCB industry.   The  project has   been  completed   and  put  in   use (making small scale PCBs).

 

       CNC machine which carries out operating commands. calculated with the help of a computer. Conventional CNC machines constructed using linear components. such as worm drives, ball races, linear guides and many other. not inexpensive — specialist components. The construction of a linear machine appears very straightforward. select the required components in the appropriate sizes, fit them together. and set the computer going. But the devil is of course in the detail: all the parts must mounted, parallel, true. and free of play, or else things will grind and jam.

      PCB drilling machine is, as far as function and aims concerned, exactly like an X/Y/Z-machine. It can handle circuit boards up to 200 mm by 300 mm with an accuracy of 0.03 mm. which is adequate for our application. Because of its lightweight construction it can move , at almost 80 mm/s. In construction it is different from linear machines. Everything reduced down to two rotating, vertical axles. The only specialist components required are good-quality ball. bearings to support these axles without play. In appearance, the machine resembles a record player. in the middle is a rotating table, on which the workpiece. the circuit board  fixed. Instead of a cartridge we have a drill, which can moved up and down. And in exactly the same way as the tone arm can reach any point on a record. the drill can get to any point where drilling required on the circuit board.

      As well as the rotating table, there is space for more tool arms. which can all operate practically simultaneously on the same circuit board. The advantages are that the job gets done quicker, and no tool changes required.

      The tool can be a drill, which can used for drilling holes for the leads of components. or a milling tool, with which the conductors can milled away. Drilling data taken from one's preferred circuit board design program in Excellon format. all programs are capable of outputting this format. Milling data sent to the machine in the HPGL plotter control language. allowing any desired cutting path to followed. The machine can connected to the printer port of an ordinary PC without extra hardware.

       The machine is not designed for heavy-duty milling operations. If you want to produce milled aluminium front panels, you will have to look elsewhere. The key feature of the machine is its high speed. which can only obtained with a lightweight construction. It is sturdy enough for working on printed circuit boards. but not sturdy enough to withstand the high sideways forces that arise. when milling metals. The machine has to be small and light enough so that it finds a place not in the workshop. but actually on the experimenter's bench

 

      PCB drilling determined by the increasing technical. and commercial requirements of the electronics industry. The rising level of. integration of the electronic components requires to improve drilling accuracy. and process reliability. At the same time. the prevailing pricing pressure on electronic devices demands a continuous step-up in productivity
