How to add pin headers at 180°?

tejaswini.nivarthi.chandra.shekar — Tue, 14 Dec 2021 05:29:15 GMT

Hi,

I am quite new to PCB design. I want to add a female 4 pin header to my board so that I can connect another part later. But I want to place them at 180° (parallel to the board) and not at 90° so that I can connect from the sides and not from the top. How do I do this? Thank you in advance for your help.

The female connector (note: Not a "pin header" - that implies male) that sits flat on the board is a different component to the one that sits vertically. Look on the stock list of your favourite component supplier - you will find they list both "straight" and "right angle" types. Similarly, when you use such a connector on your Eagle design, you need to pick the correct component type. This may be a matter of choosing the appropriate footprint / package option, or it may be a different device. That depends on how the library has been designed.

Hi One of the robs,

Thank you but I don't have any favorite component supplier as such. Is there a possibility to find one in one of the eagle libraries?

I think you're looking at this the wrong way round, aren't you?

Are you actually designing something you intend to build? If so, you need to decide what components you'll use based on what you can afford and actually source. So you need to think about suppliers first, libraries second.

If you're not intending to build it, what's the point?

If you go looking through Eagle's libraries for nice components that look pretty on your design, you may discover further down the road that what you've picked has been obsolete for twenty years because it always cost five times as much as anyone else's.

In your case, though, I'm fairly sure one of the standard libraries in the install package includes some 0.1" pitch right-angle female sockets. Possibly con-lst-b from memory but I'm at the wrong PC right now.

I know all the main components that I want to use and they are all available, as in they are, in stock. But the pin headers and connectors I did not check. Your answer also leads me to other questions and since I have never done this before as I said maybe you can answer. So is it important that all the components that I use are from a single supplier? or is it fine if some of them are available at one supplier and the rest at another supplier? Or is it important for the PCB manufacturer I choose to have all the components by himself, if not will he reject to manufacture or will he look online and buy from different suppliers?

In general, I would say there's no reason whatever to need a single source. Most of what I work on ends up needing two or three component suppliers. However...

That depends on the PCB maker. If you're having the boards fabricated and assembled on the cheap by somewhere like JLCPCB then they may only be willing to populate parts from their own stock list. (JLC are also restricted to SMD only and on one side only). If you're using a more professional outfit (at correspondingly higher cost) then they should be able to fit anything you can point them to a source for.

Thank you very much 🙂
