...I have alot of experience with parts from this corner of the world, some are good others are not. If we can identify the weak ones and find suitable replacements I am sure we can turn some of these lemons into lemonade.
i have a lot of experience with chinese mfr's too
the funny thing about chinese manufacturers is that if someone is paying them to do it, they can get really good at designing stuff.
they aren't idiots. they're just better at price scaling than we are..
if you say "make me a $0.50 opti sensor, times 10,000", they will gladly do it
....with the appropriately skilled employees, and the appropriate corners cut to make it that price.
if you say "make me a $25 opti sensor that's close in quality to this mitsubishi one", they'll gladly do that too.
the trick is, the first lot off the line is going to be half-developed and have issues. you'll have failure rates through the roof. they'll try to cut corners at first, no matter what, to see if they can get away with it.
you get back to them, tell them the issues, say they need to be resolved in the next batch to continue your business relationship. usually they are
that's not unique to chinese mfr's.. most stuff you have built in the USA or mexico is the same way.
