Abstract
A method for manufacturing an ignition coil for an internal combustion engine includes manufacturing a containment body provided with a containment chamber, defining an internal volume, and with a lateral seat facing outwards, and preparing an electronic board provided with a first face and a second face, opposite the first. The electronic board is positioned inside said lateral seat and a polymeric material with high thermal conductivity is then printed on the electronic board so as to cover it.

An ignition coil for an internal combustion engine, comprising:
- a containment body provided with a containment chamber, defining an internal volume, and with a lateral seat facing outwards, away from said containment chamber,
- electric/electronic means for generating high-voltage electrical energy housed in said containment chamber;
- an electronic board electrically connected to said electric/electronic means and arranged in said lateral seat;
- a protection element to protect said electronic board;
- wherein said protection element is made of a polymeric material with high thermal conductivity over-moulded on said electronic board so as to close the lateral seat and cover the electronic board.
