![]() Buttons are connected directly to I/O pins through internal Pull- Up resistors. Circuit diagram is shown bellow: Control circuit is very simple. ![]() The UV box is controlled by 8 bit microcontroller AT9. The intensity smoothness viewed on white paper sheet at distance 5 cm from lamps.Ĭontroller. To make all the float of light towards the PCB there is Aluminum foil used. Some technical characteristics: Wavelength, nm. 2 lamps in this exposure box on each side. LCD displays the Time of exposure, and after start is pressed it shows remaining time of UV exposure. START starts timer counter and powers the lamps through relays. When automatic mode is selected, then by pressing buttons MIN UP, MIN DOWN, SEC UP, SEC DOWN exposure time is selected. Switches UPSIDE and UNDERSIDE are used to enable upper and lower lamps separately – in case you are using single or double sided boards. MANUAL/AUTOMATIC switch is used to power l the UV lamps manually or automatically. Control panel consists of two parts: â€Power control†and “Automatic controlâ€POWER switch is used to turn on/off power of the UV box. Atmel® microcontrollers deliver easy-to-use embedded design solutions with low power consumption and high performance for a wide array of applications. ![]() First we need to tell our Arduino UNO (in my case an Arduino UNO R1), to know that whatever we are sending is not for it, but for our other micro. Atmel is a leading manufacturer of microcontrollers and touch technology semiconductors for mobile, automotive, industrial, smart energy, lighting, consumer and home. Case is made of 5mm wood board wired with screws.įirmware (Arduino sketch) file for the Arduino Data Logger.ino sketch for the 8-bit Arduino microcontroller used in the Arduino Data Logger project from the August. Searching for an electronic component? Simultaneously query distributors, and returns the responses in real time. ![]() ![]() In this article is described the manufacturing of an automatic ultraviolet light source exposure box.ĭo you know any DIY programmer to use with Codevision? I built a programmer to burn AT90s2313 from Elektor 2003 July/August edition and it works with BASCOM and. And pf course third benefit is speed and multiple replications of your boards by using the same mask. Little bit effort and you can compare results to commercial products. You couldn’t do this by using other home techniques like laser printers or hand artwork other advantage is that this method gives clean image – smooth edges of PCB tracks. Using UV light in manufacturing PCB’s has many benefits according to other methods: you can get thin tracks like 0. PCB exposure |One of more advanced PCB manufacturing methods is exposing laminate copper boards covered by photo resistive layer through mask. ![]()
