First, thank you for the comments on your country and economy.
A square foot is 12x12 inches, right? That's 244 square inches per two square feet. Two sqare feet are approx. 30x60cm. Or about 0.1 tatami.
16x10cm is 160cm^2, that's 16000mm^2, that's 1.6dm^2, that's 0.016 square meters. Decades squared.
BGAs and FPGAs are no longer advanced or expensive, 5-10 dollar toys and hobby projects contain them. Chip makers prefer them. I could place 0.35-mm pitch BGA as well as a pro machine for tiny fraction of the cost. Some hobby market board makers started supplying 6-layer boards as standard.
You are doing massive amout of jobs, not just work. Work is defined by the effort spent, in Joules, calories, BTU, etc. (or time.) In the rushtime for a deadline, I spent 40 hours in three days reworking, placing, adding and finishing some design, pages and pages of new schematics made from scratch. Roughly the work of those 4 engineers and you. The difference is that I'm not being paid for that.
I just wish you that only people who actually work on the project will comment and try to change the design, not people who did not, will not and never would work on it, like in my case, I can tell you that is hell to live. People who will care only too much and pressure you about something cheap removed, yet the next day care not at all, yet the day after happily agree to some external suggestion of adding a useless component of the same cost level. You will spend a lot time explaining why one or another design choice has been made (three times), only for the person acting surprised and shocked that such a design choice is there in some important fourth meeting. I suddenly felt dizzy after that.
I just wish that you would never ever have to suffer that, lots of people wanting something, changing opinions, goals, wanting you to make a document, then wanting you to remake that document, and after that not caring about the document the slightest bit!!! Did I mention that the document work would stop you from actually working on the design? You guessed that there would be questions why the design has not proceeded in the meantime, yes. No, that person didn't even TRY to help with that document. Saboteur.
The solution you offer is simple: change country of residence, I see that.
Will try later.
Thanks.
