Why do we care about the Inside a modern Chinese PCB factory
We come here to share how we home brew PCBs. If we want to professionally source PCBs we can choose who to support with our dollars. I don't know about you guys but I only home brew PCBs for hobby

Re: Means of going from a pdf file board image to a file to engrave from?
I used to this when I had more time than money, the only way to get really clean gerber files was to trace every line by hand with new tracks and pads. A layout software that can import pictures was

Re: Inside a modern chinese PCB factory
Standard PC boards, DS, no PTH, can be done but the chemicals are messy. Ditto but using mechanical etching, limits resolution and you need to have the etching setup. anybody price those bits? I'd

Re: Inside a modern chinese PCB factory
It costs me (neglecting my time, etchant and toner) about 3 dollars to make a 4 x 6 PC board (largest I can do with EAGLE). That's double sided, plated, but not plated through holes, Vias not under

Re: Inside a modern chinese PCB factory
First time I ever heard it mentioned was when Al gore bought it up as a debate when he ran to be president. His solution was tax all emissions, even cow farts. From what I hear, plenty of factories

Re: Inside a modern chinese PCB factory
Speaking of gluing modules together, I was reminded of this: https://www.xkcd.com/1988/ Well yeah sure it works, but it will make some of the old folk rather unhappy. Tony

Re: Inside a modern chinese PCB factory
The joys of mass production and economies of scale. Stuff that used to be expensive and/or hard to do is now easy & cheap, mainly due to automation. Making your own boards might still have its

Re: Inside a modern chinese PCB factory
You can't even buy the base material for that sort of money. Generally electronics as a hobby has changed in the last decade(s). Now it is often about connecting modules together. I mean I do this

Re: Inside a modern chinese PCB factory
Well, we were taught about anthropogenic global warming here in school - in 1986, and by the late 80s it was already a widely discussed subject. I think part of the decline of homebrew PCBs isn't

Re: Inside a modern chinese PCB factory
Well all the global warming debates, DID get heavy when China got .com capability when the internet came along and the entire globe began making purchases for goods directly from China. Think of 4x

Re: Inside a modern chinese PCB factory
There seems less and less incentive to make your own boards these days. (Also evidenced by group activity). If I have boards made for work locally it costs roughly 200eur. The same boards at

Does a bear crap in the woods? Actually this has the potential to be the worst ecological disaster the planet has ever had to deal with. Look at the sheer volume of pollution in the form of burn off

Re: Inside a modern chinese PCB factory
And apparently there's a bit of a price war going on. Once your designs (if they do) migrate to plated through holes, I suspect that the average person sends them out somewhere. Harvey

Interesting to see how this is done these days: https://www.youtube.com/watch?v=ljOoGyCso8s&ab_channel=StrangeParts And you'll never believe the prices, so I won't even write them down
