Sourcing extra tall PCB headers

[Alex Gibson]

Hi all

 

Making a long awaited upgrade board for the Thames Valley RepRaps, I’m hitting a sourcing issue which is infuriating as I was sure I sorted this before, but I lost a lot of research data.

 

I’m making an upgrade that plugs into a 40-pin ATMEGA644p DIP carrier socket.  A lot like those old BBC Micro mod boards like below:

 

 

The good news is that I can find something close still, from RS Components – but it’s absurdly expensive for what it is and would need extra pieces of stiff wire to make into a standoff: https://uk.rs-online.com/web/p/products/0402692/

 

 

Does anyone know of a good source of extra-tall PCB header strips I could use to complete this?  Or even, a complete standoff component if such a thing exists?

 

Cheers,

Alex,

Maybe you can do something with a 40-pin wirewrap DIL socket (https://uk.rs-online.com/web/p/dil-sockets/1882774/)

The problem is likely to be that the legs, although long, are probably not a good size to plug into an existing DIP  socket

Hi,

Whilst not my favorite supplier stick "20mm PCB header" (other lengths are
available) into Amazon.co.uk and you should be presented with 40 pin strips
that can be cut in two at a variety of prices.

These have square pins and may or may not fit the socket on the existing
OMC PCB. If they don't fit or to be stronger/neater solder the strips to
the back of a turned pin DIP socket.

Alternately I have some turned pin pcb header strips in my store and by
soldering these to the bottom of the pcb, I might then get away with simply
stacking multiple turned pin sockets. Probably an expensive way to go.

Thanks Bob, sometimes the solution is under one's nose...

A combination of Amazon 20mm square headers plus this https://uk.rs-online.com/web/p/dil-sockets/6742505/ will do the job very neatly I think!

Cheers,
