Patent ID: 8887384

Claim:
A method for the production of a circuit board having a reflective coating and at least one electroconductively contacted LED, whereby the reflective coating is printed onto a surface of the circuit board and a protective coating comprising one of a partially transparent and a transparent cover layer is printed onto the reflective coating by means of inkjet printing, wherein on the surface of the circuit board, first a base layer is applied with inkjet printing before the reflective coating is applied, whereby the reflective coating comprises an oxide layer with a noble metal, the method comprising: a) exposing an uppermost conductor layer to form a recess for the purpose of exposing the underlying circuit board substrate and creating an installation surface for the LED; b) disposing an electroconductive bonding surface in the neighborhood of the installation surface for the LED; c) applying a solder mask onto the uppermost conductor layer; d) printing of the base layer; e) printing the reflective coating in a surrounding region of the installation surface for the LED and the bonding surface by means of inkjet printing; and f) printing the cover layer at least partially covering the reflective coating.
