Week #3: Make-through

• Step 1: I tried to design without using bridge but I spent much without any result. deciding to use one bridge to end this error.

• Step 2: I designed great the PCP on Eagle (according to it is second PCP)

• Step 3: Lets start my fabrication of PCP with all happiness, I entered the Fab Lab door and I send to the flash memory all photos. putting the all info need for CNC machine setting.

• Step 4: It is work WOW. I can't wait to see great. It is finish the tracks. the tracks was so roughness and not finishing well. I know the problem because is in manual using of down button of machine is little big. I told to my self it is not a problem. It seem good.

• Step 5:The machine is ready to drill and I change driller. it is start. Oh no the hole is shift above its location. keep calm, I know my error ( I forget the test of photos). my mind five minute only for fix the problem. after I finished, I heard words that no one would like to hear ( It is 5:50 o'clock and please prepare yourself because we will close after 10 min). it is mean no time for fabricate PCP again.

It is not look good but there is wrong in holes position and the dimension 50mmx35mm

• Step 1: After you download Eagle come with me prepare your tools (laptop and coffee) for ten minute journey

• step 2: Downloads library of Fab (Spark Fun libraries, Fab library).

• step 3: Use all, Right click on each library and make sure you use all library (green circle). Warning, each time you use Eagle You should make libraries use all.

• step 4: Searching on component. go to left window (two columns) and you will find add part search about your components name choose ( smd or through hole = Pads). Remember, to use " if you missed part of component name.

• step 5: Finishing the schematic and go to Board, In second tool par after bar you will find button (Generate/ switch to board) make click.

• step 6: drag all your components in the area between the orange boundary stop at here.

• step 7: some steps before wiring to save your PCP it depends on the accuracy of CNC machine used follow me to save your time by saving the tracks from cutting or touching together. (clearly in the following Photos)

• step 9: layer, choose (single or double layers)

• step 8: Wiring (Route Airwire) [smd (Top layer) or Through all (bottom)] try to drag each component near to prevent the two tracks touched together. Please, don't challenge your self to use with out any bridge (zero ohm). it consumes more time but it great challenge.

• step 8: Making outer outlines, draw you outlines of PCP with width 31.49.

• step 10: Make sure your isolation is 20.

• step 11: CAM Processor files, click on CAM Processor then in the top Export as ZIP- then process job.

• step 12: gerbv viewer, Open Grebv and open Gerberfiles and change colors to white and black only. follow my Pdf files colors.

• step 13: Gimp, Photoshop program open Pdfs files and makes the resolution 1000 pixels. Image- model-indexed-use black and white- convert. You will use flip horizontal in transform if you wiring on bottom with through hole components.

• step 14: Finally, revise all photo together make sure all drills in the each photo not shift in any photos. I prefer to keep the outline frame in Pdf and remove from Gimp (PNG).

• Step 1: Setting the machine parameters. I can not wait. I revise the all error I failed in the first trial, but the machine had another opinion.

• Step 2: the PCP had two different depth of tracks. you can see in the picture ( I knowed the It is a bad elevation problem wait it is not my problem ( thanks to Allah). using some traditional techniques (that we can remove the track which is done well and keep the other and repeat tracks again with more down in of drilling tool . it is failed because of the the tracks are connected to together (some well and some not well) so that I can not remove.

• Step 3: Choosing another area in copper board. No space enough to make my PCP in the fixed board on machine. I should replace it with new one.

• Step 4: with no hope (disappointment) because it is 5;45 o'clock. I wait to hear the Fab Lab Sentence.
