In my thread on my M44D40+ module, I recently posted some pictures of an alternate version
that uses a DIP40 propeller chip on top of the stackable headers as opposed to the QFN chip on the PCB. The version will enable me to sell the module as a kit and thus be even more useful.
However, the leads on the IC are not long enough to seat into the header as deep as I would like. They do seat fine and the module works great, but it could not survive a good smack while held upside down. Yeah, I know, maybe I am asking too much, but if someone uses my module in a project that will see some shock and vibration, I don't want the socket's retention to be a cause of intermittent or critical failure of the project.
So, anyone know of any elevated stacking header strips made for ICs that don't cost an arm and a leg? The ESS-120-T-28 from Samtec is actually a PERFECT solution, but at $4.10 each, that can't be my choice. It's an elevated, machined pin, header strip with long stackable solder tails.
I am even considering using a cheap stackable header then stick a standard 40 pin IC socket into it to get my solution.
