Hi all,
I need a heatsink which can be mount on PCB with screws. Dimensions are length=19mm width=19mm and height doesn't matter. I found some heatsinks on internet but didn't find any with screws, some of them are clip mount and some are Thermal Tape mount.
If anyone know about it kindly help, I will be very thankful to you.
Regards
Tanveer
 
you could try a simple sheet of aliuminium it wouldn't be as good as the real heatsink but if you can't find any heatsink then you could use this XD

Have you looked around a recycler's yard ( metal, electronics)? You're bound to find small, usable heatsinks that can be cut to fit your application.
In my locale, there is a used metal shop among many retailers that carries heatsink extrusion panels, but not the multi-finned TO-3 panels found on power amps.
I'm working on liquid-cooled heatsinks, that use 5/16" steel pipes fed into the fins. Just need to get a 6" long 5/16" drillbit and flexible tubing.
