Assignment
No. 4 Electronics production
Objectives: Group assignment: Characterize the design rules for your PCB production process Individual assignment: Make an in-circuit programmer by milling and stuffing the PCB, test it, then optionally try other PCB processes Assignment: After group assignment I make the hello.IPS.44; because the only components in Fab Lb CDMX, but the circuit it's very used for programming the new boards created. In this task I initiate my adventure in the world of the electronics already with more force, I on having been a mechanical engineer my knowledge in electronics is almost void, but I him am going to throw many desire to learn. I begin with the image of the card that I have to elaborate, which is the Hello ISP 44, which from CorelDRAW I modify and obtain:
Figure 1. Original design hello.IPS.borad
Figure 2. Board with changes in Corel Draw
It will scheme it in her MDX Shapes 20 of Roland (For obtained data sheet click in the figure 3)
Figure 3. Roland MDX 20
I place the plate of phenolic with copper.
Figure 4. Board use for fabricated the PCB of hello.IPS.44
And by means of fabmodules
Figure 5. Fabmodules
I started with a speed of court of 4 mm/min for a cutter Diameter of the tool of 1/8”, diameter of court of 1/64”.
Figure 6. Court use the fabricated PCB
I started with a speed of court of 4 mm/min for a cutter Diameter of the tool of 1/8”, diameter of court of 1/64”.
Figure 7. PCB fabricated with Fab modules and the court of 1/64".
But after 5 attempts, I obtained the correct one ,but I had to lower the speed of court to 0.8 mm/min.
Figure 8. Five intents for the fabricated PCB.
It appreciates the difference

Already with the components I prepare to weld according to the following electronic graph:

Now testing the board with load program

Ups, I do not work, it seems that the weld is not nice … it will treat again
