Strapping fans to a PCB?

I can just imagine the reaction you'll get when you explain this mounting idea to whomever has asked you to design this, and even more so as you explain it to whomever you expect to assemble it. And it's not good.

I think you're trying to save pennies of parts costs that will result in dollars of labor costs – I'll let you do the conversion to local currency.

How about something like this mounting block from Essentia components? Screw a couple blocks to the fan, and attach it to the circuit board with screws. Essentia has all types of hardware, so they may have other useful pieces.



Keystone Electonics also has many brackets and other bits and pieces that could be pressed into service. One piece that caught my eye were these right-angle screw terminal blocks. Not their intended purpose but solder them to the circuit board and screw the fans to them.

No worries for him, he is just doing this stuff as a hobby.
