Integrated circuit

A flexible integrated circuit comprising:

• an upper dielectric layer;
• a lower dielectric layer;
• an electrical routing layer located between the upper dielectric layer and the lower dielectric layer;
• and
• an edge connection tab which is electrically coupled to the electrical routing layer and protrudes beyond a footprint of the upper dielectric layer.

An electronic circuit assembly comprising:

• an integrated circuit comprising:
• an upper dielectric layer;
• a lower dielectric layer;
• an electrical routing layer located between the upper dielectric layer and the lower dielectric layer;
• and
• an edge connection tab which is electrically coupled to the electrical routing layer and protrudes beyond a footprint of the upper dielectric layer;
• and
• an application circuit comprising a metal protrusion arranged such that, when the edge connection tab is pressed down onto the metal protrusion, the metal protrusion pierces the edge connection tab, so as to electrically couple the metal protrusion to the electrical routing layer.
