Title: 40 pin female header 2.54mm
Post by: ebclr on June 04, 2016, 04:52:10 am
Is there a Technic to cut a 40 pin header to be 5 pin without destroying a lot of pins ?

You should only have to destroy 1 pin, yes? Cut with your flushcutters, trim off excess plastic, done.

Take your stanley (craft) knife, count out how many pins you want, score down the middle of the next pin after that (unavoidably deleted), snap, clean up the snapped ends.

You want 5 pins, score down the middle of the 6th, snap, trim.

I only score one side, one knife-score is all it takes to weaken it to snap at that spot.

I just twist them and break them off where I want.

I guess since these are headers, it's the female ones that are not supposed to be snapped apart. I guess, as said others, you could sacrifice one of the pin, and smooth the remaining part.

oh, well yes you loose one receptacle, just cut through with cutter and file off as neccessary.

Its easy if you don't care about the offcut, but if you need both pieces with only one pin's waste, it depends on the shell.  If its glass filled hard plastic, you may have to use a fine-toothed junior hacksaw to notch each side of it as its hard and brittle enough that snipping it tends to damage the corner between the inter-contact separators and the sides.  If its soft thermoplastic, surface scoring doesn't work too well and you may need to remove the contact insert so you can cut it without the cut being deflected.
