Hi Friends,nice to meet you here
I want to know someone who engaged in this line such as Feeder, Nozzle, Motor,Driver, Valve,Filter,SMT machine,SMT squeeze,cable,oxygen analyzer?I just engaged in this line few days ago,I hope I can learn sth from friends here also in this line.

This forum is about the 6502 family of microprocessors. Are you wanting to control stepper motors, valves, and other things with a 65xx, and read an oxygen analyzer and other sensors with it? Please be specific. I have not done mechanical controls like that, but I have done many electronics work and hobby projects with my workbench computer shown at http://wilsonminesco.com/BenchCPU/ . It could be used also for things like you seem to be talking about, but I want to make sure you understand what this forum is about. I and others here do SMT layouts, but I don't think there is anyone here who is involved in the commercial manufacture of PC boards.

One other thing: What is this "sth" you have mentioned a few times? At first I thought it was a typographical error (typo), but now I don't think so.

What's an additional VIA among friends, anyhow?

I think it's a texting/internet abbreviation for "something".

Sarah, I think you'll be better understood around here if you don't use those abbreviations, and phrase things less... err... densely.

Welcome Sarah! As Garth notes, these forums are intended for 6502 topics and projects.

Possibly there are general electronics forums which are closer to what you need. Here's one I'm aware of:
http://www.eevblog.com/forum/

Also this Q&A site could be useful to you:
https://electronics.stackexchange.com/

And I see now that this site has some more pointers to discussion sites and reference sites:

(If anyone else knows of any general maker/hobbyist/electronics forums, please add them to this conversation!)
