Hexagon hole with metalisation

[ilghiz]

Hello,

I need several holes with complicated shapes (hexagon, etc.) with metalisation. I tried to make a component and generate gerber according to this component. However, jlcpcb do not want to manufacture it without reasonable explanation.

Since I am new user, I cannot upload here, so I just put plain text of my *.kicad_mod file below.

Thank you

It would be more fruitful to be able to see the board instead of just the footprint. Anyways, I don’t wonder they want confirmation.

[ilghiz]

Thank you for the replay.

I placed Gerber - it is really simple! However, jlcpcb do not accept it.

Please, suggest me how to improve my footprint.

Thank you!

You were not specific. Perhaps this will provide ideas…

1. A Round Insert with Hex-shape hole to be Pressed into a round hole on PCB.

2. A Flange-Nut to be captured in a Hex-Shape cutout (in edge-cut layer). I did NOT bother to make the edges line up with the Hex Nut’s shape…

In both cases, I made a Step file for the insert and used it to make a Footprint-Part.

You could download free Step file of stock inserts/nuts…

Without the exact message from your manufacturer we really can only guess what might be going on.

Until we have that info a general info from my side:
Be aware that sharp inside corners might not really be manufacturable.

Ask what the minimum radius is that can be made (after metalization) and make sure whatever goes into the hole still fits with that radius applied (you might need to have partial circles in the corners for corner relieve).

Oh and if you indeed want to have a hex hole for capturing a nut then maybe these could be an alternative: https://www.we-online.com/web/en/electronic_components/produkte_pb/produktinnovationen/smtspacer.php (There are footprints for all of these already in the official library)

You show as ‘leveled up’ so you should be able to upload now.

Any PCB that requires plating after routing is a special and cannot use any of the low cost manufacturers.

[straubm]

JLCPCB does it w/o extra cost. I have it all the time with plated slots.
