For our Amazing Assembly services we offer other technologies (different copper thickness, colors, silkscreen, etc). The only limitation there is, that your projects needs to be prototypable with one of our Prototyping Technologies above. If you have further questions, feel free to contact us here
Just discovered this service. Looks very promising!
I would very much prefer to order in EU and Germany than from China. Are you planning to add any more colors than green, for the solder masks (like white and black)?
I have a beginners question: I see from the FR4 data sheet that the glass transition temperature is 140°C. How does this work with reflow soldering? For normal lead-containing solder paste, I have to heat up to 200°C. If I do that on a hot plate, then the whole PCB will heat to this temperature…
I tried looking for the “Scalable Series”, but I cannot find this anywhere in your online information. I want to order small numbers of boards, as in the prototyping “Beautiful Boards” series, but would like to choose a different color for the solder mask, and choose a thinner board material (.031 = 1/32" instead of the standard 1/16", .062"). How do I do this?
Thank you, Christina. I did not realize that the “assembly” form could be used just for a PCB manufactured board (with no actual component insertion or other “assembly”). I filled in the request and uploaded my KiCAD project files. Thank you again.
Hello, first, thank you very much for this information.
I have a question about copper thickness. In the Table provided, there are two different values, called “Base copper thickness” and “Min. processed copper thickness”. I don’t understand exactly what they mean?
The “base copper thickness” describes the thickness of the copper foil of the base material at the beginning of the manufacturing process. In the electroplating process step, the copper foil is enriched with additional copper wherever copper structures are intended. (This process step is essential to form a copper sleeve in the drill holes and thus to connect different layers).
Finally, tracks and surfaces have the “minimum processed copper thickness”, which is made up of the “base copper thickness” and the additional copper added by the electroplating.
(For inner layers, a copper foil with 35 µm can be used from the beginning. In contrast to the outer layers, the copper structures are not enriched with additional copper here. Copper is deposited only in the (plated) drill holes.)
Thanks, now the link in the above table under “Stackup” works.
I got this URL from a Google search and wondered if it was the right one.
By the way, I downloaded your Eagle design rules from github and found that they show a PCB thickness of 2 mm. Glad to know the correct value now. Hopefully, thinner PCBs will be offered too in the future.
I’m new and eager to order my next project here!
Thank you very much for the Info on top.
I searched the forums and didn’t find an answer to my question, so i’ll just dump it here, if misplaced feel free to move.
I am often designing proto boards to carry bare sillicon dies, these are then wire bonded to the PCB. Wire bonding works well on copper (or gold of course) and is very bad on tin layers usually found on PCBs.
Could I order a simple 2 layer board containing only bare copper, so no tin on the exposed copper ?
If so, how would I specify this in my Gerbers ? (using Eagle for example)
If I understand you correctly, PCBs with an ENIG finish should solve your problem. If you select Beautiful Boards HD all exposed (= not covered with solder mask) copper pads/planes will get an ENIG finish.
You can make the selection after uploading your project in the project overview. (Btw: You can upload your EAGLE .brd-file directly to us!)
