We tried 3 times and finally we make it, but still many things should be considered. How do you guys to fabricate this?

 

We get professionals who know WTF they are doing. Life is to short to mess around learning commodity skills.

#1 Google Hit. I've used these guys -- they did good work.

Thanks. Just what I need for the Hall Effect sensor on my water softener.

What was so hard about fabricating that flex circuit?

 

1) Materials are hard to find
2) Thin stuff is really hard to drill
3) Messing with nasty chemicals is no fun
4) Your homemade flex circuit is going to be poor quality

Like Papa said, it's a commodity skill, learning this has no career or strategic value.
You could make homemade tires for your car- but you wouldn't.

 

Maybe they are trying to start an offshore flex circuit fabrication company. Too bad they're two decades behind the curve. Better luck next time fellas.

 

Wait for it...

I'm sure we'll hear an spam-vertisement from the OP in a day or two.

That depends on the design requirements. Some of the manufacturers are using laser cutting, mechanical routing, steel rule dies and chemically milled dies methods for final fabrication.

Thank you, I will have a look.

You mean your sensor needs this kind of circuit?

Only the location of "Golden fingers", cause they are hollow.

1)We use FFCL (polyimide+copper)
2)laser drill we can use
3)If we can fabricate well, I believe they are useful, after all, flex circuits are widely used in many electrical applications. How do you think?

So two decades ago, you've started source flex circuits oversea?

But the difficult point is the location of "Gold Fingers", they are hollow.

We made flex circuits here two decades ago.

That's quite good, so have you some suggestion for the hollow gold fingers? Thank you in advance.

You misunderstand. I was a user of flex circuits, not a maker. I went to the people who are professionals and had them do the work for me. I was satisfied with the results. You should ask the people who do this for advice. It was not clear to me if you are a user or a maker of flex circuits.
