FIELD: electricity.
SUBSTANCE: dispersion is obtained by mixing liquid adhesive to filler from metal brazing alloy powder, and after dispersion layer is applied to substrate, it is dried, and heating of dispersion is performed by means of laser with emission power providing evaporation of adhesive component and melting of brazing alloy particles.
EFFECT: lower polluting emissions and improved manufacturability of electroconductive tracks during production of printed-circuit boards obtained by application to the substrate surface of dispersion layer, local heating of dispersion in places corresponding to the pattern of electroconductive tracks till adhesion of sipersion with surface of substrate, and removal of unused dispersion from substrate surface.
