Published Powerboard Tyche PCB reworked source

Finally, the reworked PCB design source of Powerboard Tyche with the updated available components is ready ( in older posts you can go more deep about “our” electronic components shortage issues). This work was made using Mentor Expedition and it is ready and uploaded into our repository with all reported issues fixed, including issue number 5, the last one corrected . Thanks to our collaborators we are able to export this work using Altium form so the next days we will publish it and we will try to convert it to Open Source Kicad format ( and probably loosing something in the conversion process) . In our older post we have give more details regarding the PCB sources.

Inside Output folder you can find many interesting files easy simple viewable like the “the plot separate sheet” CAM350/DFMSTREAM and the Motherboard Assembly TOP and BUTTOM.

As a conclusion now we have everything to produce and make the hardware tests in September.

In July we have published more details about the rework design due to the global shortage of electronic components

Rework of a part of the mobo and situation of the components

As you know, we were having troubles to find a few components in the marked (listed below) not only because of their availability but also due to the increased price. After an extensive research, the designer was able to identify the replacement components.

Below, a detailed list of unavailable or extremly expensive parts that the designer is replacing with other readily-available components:

• 1 per pcb Transistor: NPN; BSR17A bipolar; 40V; 0.2A; 0.35W; SOT23 – ON SEMICONDUCTOR > 3100>#/strong### cost increase from 0,5 euro to 16,50 euro per piece
• 4 per pcb Field Effect Transistor –NDC7002N MOSFET 2N-CH 50V 0.51A SSOT6 – ON SEMICONDUCTOR : >1100>#/strong### cost increase from 0,50 euro to 6,5 euro per piece
