This morning we mounted the new version of the picus wifi (now has definitive name FLYPORT).
The difference with the first version are:
1. PIC microchip 24F (was 64k flash, now is 256k)
2. PIC microchip 24F (was 44 pins, now is 64pin)
3. Quarz (was 28Mhz and quite big, now is very small and 32Mhz and we added a second quarz for the RTC 32.768Khz)
The complexity of mounting is a little increased since the pitch of the new PIC processor is quite small, but we did it without problems.
We use MANTIS optical system and a very small soldering iron to place and solder the prototypes. Here’s what we see on Mantis during mounting:
Here’s the board almost mounted:
And finally everything is soldered:
Tomorrow we’ll start electrical testing and we’ll run some testing software to check that everything is properly connected.
We hope that this is the last prototype and before end of July we want to start the first 500pcs production batch.
