<p>Created Page + Added Basic Categories + Info</p> <p><b>New page</b></p><div>=Basics=<br /> <br /> - Part of the [[Open Source Advanced Materials Construction Set]]<br /> <br /> - Essentially a better [[Open Source PCB Photoengraving System]] (ie smaller traces can be made;to CPU Levels instead of PCB Levels)<br /> <br /> - A device that uses a photosensitive maskant and a laser/dlp projector/electron beam to create the traces in the maskant. This is then etched using a chemical etchant<br /> <br /> <br /> <br /> <br /> <br /> =Used For=<br /> <br /> - The [[Open Source Advanced Electronics Construction Set]]<br /> <br /> <br /> <br /> <br /> <br /> =Industry Standards=<br /> <br /> -<br /> <br /> <br /> <br /> <br /> <br /> =Existing Open Source Devices=<br /> <br /> -<br /> <br /> <br /> <br /> <br /> <br /> =Minimum Viable Product=<br /> <br /> - Fast<br /> <br /> - Easy to Use (upload file and press print)<br /> <br /> - Recycles its own / can use recycled chemicals<br /> <br /> - Cheap to run<br /> <br /> - Scalable (both in physical size ,and precision/ability (ie pcb engraving at the low end and cpu manufacture at the high end)<br /> <br /> <br /> <br /> <br /> <br /> =Basic Design=<br /> <br /> ==Feedstock Module==<br /> <br /> - 1 or more of these<br /> <br /> - Holds PCB&#039;s, Silicon wafers etc<br /> <br /> <br /> <br /> ==Conveyor Belt Module==<br /> <br /> - Carryies feedstock from the feedstock module to the next module<br /> <br /> - should be relitively unreactive (ie Plastic or ceramic)<br /> <br /> <br /> <br /> ==Prewash Module==<br /> <br /> - Washes and dries the feedstock to prevent contamination errors in the next modules<br /> <br /> <br /> <br /> ==Photoresist application module==<br /> <br /> - Applies the Photoresist<br /> <br /> <br /> <br /> ==Exposure Module==<br /> <br /> - Exposes the photoresist to light<br /> <br /> - Can be either a pattern in front of a UV Lamp, a laser, or a DLP UV Projector<br /> <br /> <br /> <br /> ==Post Exposure Cleaning Module==<br /> <br /> - Cleans off the exposed photoresist <br /> <br /> <br /> <br /> ==Etching Module==<br /> <br /> - Is a bath of chemical etchant that the conveyor belt dips into<br /> <br /> - Dissolves the areas not protected by undeveloped photoresist<br /> <br /> - May use plasma etching instead at this level (possibly)<br /> <br /> <br /> <br /> ==Post Etching Cleaning Module==<br /> <br /> - Removes the Etchant<br /> <br /> <br /> <br /> ==Post Processing Module==<br /> <br /> - Removes any remaining photoresist + delivers the finished product to the end of the conveyor belt<br /> <br /> <br /> <br /> <br /> <br /> =BOM=<br /> <br /> -<br /> <br /> <br /> <br /> <br /> =See Also=<br /> <br /> -<br /> <br /> <br /> <br /> <br /> <br /> =Usefull Links=<br /> <br /> - [https://en.wikipedia.org/wiki/Photoengraving Wikipedia Page on Photoengraving]<br /> <br /> - [https://en.wikipedia.org/wiki/Photolithography Wikipedia Page on Photolithography]<br /> <br /> - [http://www.tomshardware.com/picturestory/514-intel-cpu-processor-core-i7.html#s1 How CPU&#039;s Are Made]</div>
