5mm Pitch PCB stacking

[tibibs]

Hi,

I am facing a simple issue and I am struggling to find an adequate solution.

I have 2 PCBs that I am stacking with some headers.
1 of the PCB is designed by me and the other one is a standard board from a third party.
On this last board, I need to connect to my PCB above 4 pins with a 5mm pitch, and I can't get my hand on proper headers for this.
Can anyone recommend me a solution or different options that are on the table?
I would like to keep the 2 PCBs removables and trying to avoid wires.

Any ideas? I can find pins but can't put my hand on some female sockets for the pins. I wonder if any of you would have some work around?

Thank you,

Tibibs

just use the length of regular 2.54mm headers and snip out every other pin? what kind of header pins ya got? you can usually just pull them out with pliers

Just regular SIP sockets chopped up?

Maybe…
Take out every other pin…

[push down and the nut helps preserve the pins for solitary use]

They’re 2.54mm apart, each so 5.8 may not work for removing every other pin, but just solder individual sockets…



I’m having trouble picturing your dilemma — maybe post pics of the two boards to illustrate?

Edit — I got pipped to the punch.

component name: male female pin header. Easy removable.

my experience, sometimes get loose. I do like reinforcement solution like @Brett did https://forum.pedalpcb.com/threads/mos-tron-envelope-filter-dylan159s-chewborg.21961/

Will the 5mm pitch male headers fit into a 2.54mm pitch female header? (0.04mm per pin doesn't seem like it'd be a deal breaker)

If so, can you use the 2.54mm female header on your PCB and the 5.0mm male header on the 3rd party PCB?

The male headers would skip every other pin the female header, no clipping of pins needed. (assuming you have access to the layout files for your PCB and can make that modification)

It will work, up to a point. Once you get into extended ranges, the differences will become more noticeable. If that's not eloquently explained, let me try to be more concise. If you use a 2.54mm spaced header and snip out every other pin, it may work okay up to about 6-8 pins, depending on the excess drill diameter of the pad that's allotted for during the design stage of the board. It's once you start getting into higher pin counts is where you start to run into trouble because that .04mm that you're adding at each pin is cumulative and will eventually become greater than the excess pad hole diameter in the design.

Basically, if your board is designed loose, like sleeve of wizard, you may never notice any issues. Otherwise, it's kind of a crapshoot and will require some test fitting.

Slight thread drift, but using a nut as a support to push out pins is brilliant. Holding a socket in my fingers while I try to push with pliers hurts so much... no more!

Nut from a mini-SPDT switch is the perfect size.

Also, you can just use the loose pins and then not worry about 2.54 pitch — instead you worry about the fragility of the pins without their plastic-surround support.
