I use .1" SIL and DIL connectors in various styles according to what I'm doing. I'll etch a small number of boards and mount an SMD header if it's attaching to a flat surface and use a 'flying' connector with crimp terminals to connect. I only use this system to connect various parts of more complex guitars with synth/piezo/magnetic combinations where I need to be able to easily swap out sections for troubleshooting or changes. .1" connectors are available in SMD, through-hole, crimp and solder bucket formats in all kinds variations. Plus they're inexpensive.
