Soldering two PCBs or Perfboards together?

Other Hardware General Electronics

Hi,
I'm confused about the way one PCB should be attached to another. I'm currently doing some project that I want to use a LCD1602 screen directly on a perfboard. If I install female headers on the perf, and male on the LCD, it seems like a huge vertical burden on the dimension, so I don't want to do that. However, when I tried to insert the already populated LCD PCB into the perf, it seems like the male header is too long on the other side. So anyone got good tips on how to joining two boards together? I wonder if there are any headers out there that are short on both sides. :slight_smile:
Thanks a lot!

That's where these are for:

Hahaha I once thought of that.. but the pin headers comparing to those on a resistor etc are "fat" and is it easy to cut a whole line? :slight_smile:

What's preventing you from finding out?

You cut them one pin at a time. Simple.

They will fly off when cut - wear eye protection, or limit the flight of the cutoff pin somehow.

Just put a finger on the end of the pin when you cut it.
