Don’t find what you are looking for?

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)?

hi @anders-weijnitz-gmai , welcome to the community :slight_smile:

we haven’t documented this anywhere, but for our series assembly you can switch color and copper thickness. the prototype you will have to run in the available configuration.

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?

hi @maxman in this case just contact us here: AISLER Assembly Request a Quote Form

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?

Best regards,
GC

Hi @gchancel102 ,

Welcome to the community!

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.)

Cheers,
Manuel

Hi @Manuel-from-AISLER!

Thank you so much for your feedback, you answer perfectly to my question.

Have a good day,

Hello. Is a two layer board 1.6 mm thick?

Hi @wiegell ,

Welcome to the community!

I have moved your question from Design Rules, as it is better addressed here.

Is a two layer board 1.6 mm thick?

Yes, all boards (2 & 4 layer) have a thickness of 1.6 mm. Please also see the table in the first post.

Cheers,
Manuel

The links to the stackup have been dead for months now, PLEASE correct that!

I wonder if 4-Layer HD PCB Stackup is the only information on this topic.

What is the minimum wire width and spacing that the factory can process?

Hi @t-wesenberg-wenzel-e ,

Welcome to the community!

The links to the stackup have been dead for months now, PLEASE correct that!

Which links are you referring to? The two links to the 2-Layer-HD and the 4-Layer-HD (last row of the table) should work. In any case, we will add the missing links for Blitz/Budget to the table!

I wonder if 4-Layer HD PCB Stackup is the only information on this topic.

At the moment, yes. What information is missing in your opinion?

Hi @Herr-Mie ,

You can find this information in our design rules here .

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.

Hi All,
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)

Thank you in advance.
Best regards,
Patrick

Hi Patrick (@timeout ),

Welcome to the community!

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!)

(If your board receives a complex rating, ENIG will be the only possible surface finish. You can find more information on this in our Design Rules.)

Cheers,
Manuel
