Abstract:
A method (200, 300, 500) for producing an electrically conductive pattern on substrate (202, 402), comprising: providing electrically conductive solid particles onto an area of the substrate in a predefined pattern (508), where the pattern (403) comprises a contact area (404B) for connecting to an electronic component and a conductive structure (404A) having at least a portion (414) adjacent to the contact area, heating the conductive particles to a temperature higher than a characteristic melting point of the particles to establish a melt (510), and pressing the melt against the substrate in a nip, the temperature of the contact portion of which being lower than the aforesaid characteristic melting point so as to solidify the particles into essentially electrically continuous layer within the contact area and within the conductive structure in accordance with the pattern (512), wherein the thermal masses of the contact area and the at least adjacent portion of the conductive structure are configured substantially equal.
