Electronic module for generating light pulses for LIDAR applications and method for manufacturing the electronic module

A method for manufacturing an electronic module for generating light pulses, comprising:

• providing an interface card, having a first and a second side opposite to one another;
• coupling, to the interface card, a lighting module having a front side and a back side and housing one or more emitter devices that emit said light pulses and have a common biasing terminal on the back side and respective one or more dedicated biasing terminals on the front side;
• and
• coupling, to the lighting module, a driver module configured to generate biasing signals of the one or more emitter devices for controlling generation of said light pulses,
• shaping the interface card on the first side to form a recess;
• forming an electrical contact pad on a bottom of the recess, the electrical contact pad being electrically connected by a conductive track to a through via of the interface card, the through via forming an electrical connection towards the first side;
• arranging a conductive adhesive layer, or layer of glue, on the common biasing terminal of the lighting module;
• arranging the lighting module in the recess and coupling the common biasing terminal to the electrical contact pad by the conductive adhesive layer, or layer of glue;
• forming respective regions of conductive solder paste on the dedicated biasing terminals and on the through via;
• arranging the driver module so that it faces the front side of the lighting module and the first side of the interface card;
• and
• electrically coupling the driver module to the dedicated biasing terminals and to the through via by said regions of conductive solder paste.
