The idea of a chip with pins in the form of a plug.

The big problem is the microcontroller pins, which often break and make the chip unusable.My idea is to use the terminals of the microcontroller as a plug, on which you can immediately put the socket on and attach the microcontroller with screws. In such an implementation, there is no need for textolite, you do not need to spend copper on the tracks on the board. Tin is not wasted for soldering. We already have less and less minerals, moreover, a lot of garbage appears. I think this segment of the market will be in demand by those who like to design and model electronic circuits using microcontrollers. For such development hobbies, as a rule, a prototype is done on which everything is tested and debugged, it is very convenient not to waste time and money on additional details, when everything is done so well in Atmega16 that it does not need additional components for conclusions.

The bigger a package the more expensive. Plastic quantity impact price. Coplanarity, quality contacts and field return msy become a concern. DIP packaged are now deprecated. On the other spectrum are lcd drivers in dual staggered rows of 25um gold bump pitch used as COF chip on flex with ACF to avoid soldering?

DIP case, just drawn in a large form. Contacts can be made smaller, here the idea is displayed. Dimensions can be made larger / smaller and the contact can be soldered if necessary.

This would make chips huuge, it would be nice for developing but 99% of chips are used in production stages not development
