Ultraviolet light source UV 8. PCB exposure One of more advanced PCB manufacturing methods is exposing laminate copper boards covered by photo resistive layer through mask. Using UV light in manufacturing PCBs has many benefits according to other methods you can get thin tracks like 0. Atmel microcontrollers deliver easytouse embedded design solutions with low power consumption and high performance for an array of applications. PGM09825 This new version uses an SMD 5x2 header. This is a simple to use USB AVR programmer. It is low cost, easy to use, works great with AVRDudehttpladyada. CodeVisionAVR Standard.

Do you know any DIY programmer to use with Codevision I built a programmer to burn AT90s2313 from Elektor 2003 JulyAugust edition and it works with BASCOM and. The insystem programming ISP programming method is functionally performed through SPI, plus some twiddling of the Reset line. As long as the SPI pins of the AVR.

Little bit effort and you can compare results to commercial products. And pf course third benefit is speed and multiple replications of your boards by using the same mask. In this article is described the manufacturing of an automatic ultraviolet light source exposure box. Parts for UV box. Case with organic glass. Panel. UV lamps ballasts and starters. Controller. Case. Case is made of 5mm wood board wired with screws. Making a control panel. Control panel consists of two parts Power control and Automatic controlPOWER switch is used to turn onoff power of the UV box. Green LED indicates the ON. MANUALAUTOMATIC switch is used to power l the UV lamps manually or automatically. Switches UPSIDE and UNDERSIDE are used to enable upper and lower lamps separately in case you are using single or double sided boards. When automatic mode is selected, then by pressing buttons MIN UP, MIN DOWN, SEC UP, SEC DOWN exposure time is selected. START starts timer counter and powers the lamps through relays. STOPCLEAR is not implemented yet. LCD displays the Time of exposure, and after start is pressed it shows remaining time of UV exposure. UV Lamps. There are used 8 PHILIPS TL 2. W5. 2 lamps in this exposure box on each side. Some technical characteristics Wavelength, nm. Power, W2. 0Voltage, V5. Current, A0,3. 7Cap. G1. 3A, mm. 58. 9,8. B, mm. 59. 6,9. C, mm. D, mm. 38. All view of lamps installed. To make all the float of light towards the PCB there is Aluminum foil used. It also makes illuminations smoother. The intensity smoothness viewed on white paper sheet at distance 5 cm from lamps. Controller. The UV box is controlled by 8 bit microcontroller AT9. ATMEL. Circuit diagram is shown bellow Control circuit is very simple. Buttons are connected directly to IO pins through internal Pull Up resistors. When button is pressed the 0 level in port input is generated, which triggers an action. Buttons MIN UP, MIN DOWN, SEC UP, SEC DOWN are used to select UV exposure Time. START is for starting Exposure and count down. LCD displays time remaining. There is standard HD4. U LCD 62 characters used. Lamps are controlled through 5. V relays. There you can see some Pictures of PCB. Lamp control and power source. UV lamps are connected in series of 2 and then ballasts are connected. Starter is connected to lamps in parallel. Upper and lower covers of box can be controlled separately by using switch. In this circuit you can also see power control for microcontroller and relays. Putting it all together. First test. Other examples you can see in my ARM section. Download source code Source Code.
