Status update of the order with pbcway.com
1.- The service is impressive. There is a person following the order that I can email ! It is always the same person so there is no need to explain again an again the history. It is the first time that I see such a good service.
2.- They have questioned the designed in a number of places:
I have been told that an engineer with review the new version and the comments tomorrow.
- 2a - the PADs where the controller will go were not marked as PADs in the Gerber file. The reason for this is rooted in the import process from the generic CAD tool (Deltacad) in the PBC tool (Diptrace). During the import, one can state if the import shall be done as "traces" of "pads". I used traces so our PAD was marked as trace and therefore would have been covered by the green isolation layer.
This has been resolved in a version 0.49 that I have sent them. I separated the PAD components in a different Deltacad layer that I imported separately into Diptrace. They confirmed that this trick did the job.
2b.- the have also questioned all the PCB areas that are not connected anywhere.
I have sent this explanation (included the typos):
I know that is strange.
The PCB is kind of tricky.
I think that it is correct in the version 0.49. Please confirm that you will use the version 0.49.
The PADS are isolated from the rest.
The complete PCB shall be covered by isolation layer but for the connector that I have sent you (and I send again)
As I said, it is not a normal one. It is used to create capacitors between the rectangles on the upper and bottom layers. There are areas that are not connected. They are just sitting there, to act as capacitors.
The PCB will be used to sense key presses of a keyboard.
In any case (attached an image that explains also), each key is a pair of two PADs on the top layer (rows) and one on the bottom (columns).
In the top layer, one (BIGGEST) of the two pads is disconnected. Isolated
The other (SMALLER) is connected to the sensing row.
On the bottom layer, the BIGGEST pad matches the disconnected one on the top layer.
The complete PCB shall be covered with isolation but for the PADS on the connector that I have already sent you and I send again.
Hopefully this clarifies.
Please confirm that the version 0.49 will be used !!!
