Contract circuit board maker source?

Try

Just checked them out, that's three 2.5" x 3.8" boards. Too expensive for what I want to do.

they have a 3 boards for $51.00 but they don't specify the size etc. they maybe large boards in which case you could mask multiple copies of the same mini board on the larger one and then slice them up your self using a scroll saw. i am not sure, look at the sight.

I have tried those products and I do not recommend them. It is very difficult to get a layer which has the same thickness everywhere, and that ruins the etching process.

It is much better to buy readymade photosensitive pcb board material.

If you choose to make your own after all you can spray in the middle of the board and then rotate the board very fast (with a motor) to spread out the photoresist evenly in a thin layer. I have not tried this but I heard about that method.

Or mount two boards on each side of the rotation center, spray the inner edges, rotate fast to force the liquid to flow over the whole surface, and the excess liquid is thrown off the outer edge.

You also need to do it in a dust free environment which can contaminate the photoresist before it has dried in an oven set to low heat.

Hello, You can send your file to me. We can help you to do these boards. Only

I am interested in the communication possibilities between China and Europe, and maybe you can tell me something about that.

I understand that you send most of your products via airplane or oceangoing ships, but is there a possibility to send products by truck, through central Asia?

That should be a more economical way to send products from China to Europe than by airplane, and faster than by ships, going around the whole eurasian continent.

Do you know how the roads are in China, from China to Kazakstan and from there to Europe?

Is that possibility used by chinese producers, or are there problems which make that alternative less attractive?

Hello Roger, Very gald to see your answer. Yes, you are right. We send most of our products via airplane or oceangoing ships. You know if we use your suggestions to transfer the products using truck s. No truck go directly from one country to another one. I can not promise to you if the products can send to your hands. Maybe will lose very easy. We all do not want to see such thing happen. Do you agreee? So I think the best way is by ship the first, the second by air. For further discuss, you can send mail to me. Send to fjq at qingdaonews dot com.

Best regards, Feng

Yes, I think I understand. But sometime in the future we will see better and safer transport infrastructures through central Asia. An infrastructure which promotes peace and equality between all people on the eurasian continent.

Yes, for urgent orders airplane is the best, and for big volumes ship is best, even if it takes a week or two to Europe.

Not necessary, but thanks anyway.

I guess that means I need to take credit for this mess. Sigh. Apologies to all concerned. It is

No 'e'.

There are two URLs here. One with, one without an "e".

The one "without" is a straight HTML site and will display in Dillo, which has no bells or whistles. Not even frames.

The one "with" is 99% Flash.

This may account for the differing experiences of subsequent posters to this thread

A nice and well functioning site, I wish more companies had so good sites. Honors to the web designer at

The one with e is a french site based in Marseille, and the site does not seem to be functional at all, as far as I can see. The flash animation just sits there and blinks a little, showing some phone numbers in Marseille.

You'd be doing some spotty-faced web "designer" out of his exorbitant fee :-)

Yeah, probably.
