Fat-pin TDA7292 Prototyping
« on: October 22, 2013, 05:50:38 am »
I've just bought a TDA7292 40+40W Audio amp from ST, and it comes in this quite easy to use Multiwatt-11 package, the only problem is that the pins are too fat to put through a stripboard...
I don't know if there's any I can get that have larger holes, but there's no way I can print my own PCBs so that's out the question. Any ideas? Adapters maybe?
Thanks  :)

Why not taking a drill bit (1.0 mm) and drill from bottom to top (to avoid ripping off the pad)?

Or maybe I don't understand the question right!?

Got any non-machined ic sockets? I use them. up to quite large legs fit in them.

That could work, but I'd probably cut the trace in the process...

Take 2 boards and place back to back so the traces are on the visible side. then place the sandwich between the leg rows and solder to the legs. that way you have a breakout row on each side to solder to the veroboard via short wires.
