Well, for now not enthusiastic about the component availability.
This is what i was able to populate.

Positioning issues are a huge time sucker.
For now i think i am sticking with PCBWAY for this kind of boards.
The risk of making errors not having a professional doing the positioning is a huge bummer for me. If I screw this two times, my customer is going to kick me where the sun doesn't shine.
Something odd ball going on with your 5 Pin SOT-23's They all seem 180degrees out.
Depends on whether it is a hobby project or not.
A lot of hobby projects I'm much more willing to put time in versus money, even if my "time" is worth more.
Commercial projects where engineers cost £30+ an hour then it's harder to argue when you are saving only £100 or so...
but at that point is it really cheaper than elecrow, pcbway or some other full service PCBA?
a good reason to use asymmetrical packages, then it is at least obvious when the rotation is wrong
* inspection is going to be minimal to keep price down
* process is heavily automated, so you don't get an expert technician reviewing it
* how much do you trust yourself getting the positioning right?

The process is better controlled than you're suggesting. They're basically able to offer these boards for this price because your PCBs are being pooled onto the commercial PCB production line otherwise it wouldn't be commercially viable. The manufacture files are reviewed and fixed by their technicians, rotation fixed, placement fixed etc (up to a point...)
44-47k Stiring.. is about 22.5 / hour.

I was referring to the assembly not the PCBs
I wouldn't necessarily expect such a process to spot the more annoying centroid file quirks however, the main one being if you have incorrectly defined your component centers so they instead show Pin1 or some other arbitrary co-ordinate. (although even that isn't out of the question if they can overlay placement data onto gerber)
mine came
first image is took by mirrorless camera.
you guys can check quality.
I think not bad for SAMPLE.
I am still fixing my pcb now.
Since I am in korea, so I will start mass product with korean local company.

thanks, looks very good, whats with the optos though? Are you using them for low voltage isolation and not high voltage?
