INTRODUCTION
Prototype is a rudimentary working model of a product or information system usually built for demonstration purposes or as a part of the development of a process. It comes fro Latin word proto means original and typus means form or model. Like on our exposure it is original but we remodeled the design and the circuit. Exposure box, is a one of more advanced PCB manufacturing method is exposing laminate copper boards covered by photo resistive layer through mask. Using our compact fluorescent lamp in manufacturing PCB’s has many benefits according to other methods. You can get thin tracks like 0.2mm you couldn’t do this by using other home techniques like laser printers or hand artwork. Other advantages this method gives clean image, smooth edges of PCB tracks. Little bit effort and you can compare the results to commercial products and of course third benefit is speed and multiple replications of your boards by using the same mask. Exposure box is a one of the electronics device that can contribute a big help for the electrician people who works in the field of electronics. Exposing time is so very wasting of time and effort so we decided to make an exposure box with timer and buzzer so that while exposing of your PCB design you didn’t to wait in the front of your exposure box, just do other thins to make all accomplished. If the 15 minutes will reached it is alarmed that is the signal that your exposing time was finished. You save more electricity, time and most of all your effort. The function of this exposure box first place your PCB inside of our portable digital exposure box and close it. After that plug in and switch on and the timer will start to count from 15 to 0 count down timer.
CONCLUSION: On our projec
