Hi Patrice

Thank you for clearing up several things on the Ukrainian forum as they answered some questions that I had as well.


1. I got proper quotes for the PCB manufacture from PCBway. For our board with size 56x88mm we get:
5x = $10
10x = $10
15x = $25
20x = $28
25x = $31
30x = $33
(all prices in US$)

Shipping with DHL is $25, HK post = $11. DHL will deliver within 2-3 days, HK post within 4-6 weeks. PCB manufacturing usually takes 2-3 days only.


2. Brendan, ChipQuik is the weapon of my choice. It works well even with just a soldering iron and no heat gun. Once I won a bet by desoldering 100-QFP chip with just ChipQuik and a soldering iron

3. Brendan, what do you think about modifying the PCB to have a separate power supply for the Peltier? That way we could use 12V or even 16V for the Peltier and 7-ish V for the rest of the circuit (I forgot what the real minimum is, will have to confirm on the Ukrainian forums). It would greatly reduce the heat generation on the PCB but we would need an extra pin. We would also need to use a common ground for both, somehow...
