Is It Possible to Find This Component ("Hammer Header") in AliExpress?

Wed Feb 21, 2024 9:14 pm

Hi all


In an older thread, I asked about connecting a Female Header to RPi,
without soldering the header to the board.

The user thagrol recommended me this component:

https://shop.pimoroni.com/search?q=hammer


It can be pushed into the RPi board, without soldering.


Is it possible to buy it in AliExpress instead of pimoroni?


I tried searching AliExpress for hammer header,
but no success with that term.

Maybe it has other names?


Thank you

IIRC they're Samtec solderless press-fit headers. I don't know the part numbers so you'll need to go dig in their datasheets for that.

That is a regular header that needs to be soldered.

It's also expensive: https://shop.pimoroni.com/products/male ... 0476117383. More expensive than the hammer type: https://shop.pimoroni.com/products/gpio ... 5643241098
Knowledge, skills, & experience have value. If you expect to profit from someone's you should expect to pay for them.

All advice given is based on my experience. it worked for me, it may not work for you.

You could just learn to solder.
Oh no, not again.

In a couple of clicks I found this:
https://www.pishop.us/product/hammer-he ... connector/

I have repaired boards before that utilized solderless headers (Cisco router blade), and the connections were surprisingly good. However, the plated through-holes were probably of the exact size specified by the manufacturer of the associated connector, and there is no guarantee like that here.

Soldering is your best bet.

When making a project with a Pi or other board that has holes for headers or wiring, I'll plan ahead and only solder in only what is needed (either a wire or a pin). I would not solder in one of these press-fit connectors because if the fit is correct, you'll most likely pull out the plated through hole if it was ever necessary to desolder it.

For some people, that's not an option.

Eugene’s fishing line header hack for Raspberry Pi Zero also works if you don't mind a little ugly:

That's 0.38 mm / 5.4 kg test Trilene laced through the holes.

I have to laugh a bit, however this is probably a hundred times better than some of the single pin female header plugs I've come across.
