A method for assembling micro-components to a carrier substrate, said substrate being provided on at least one surface with assembly locations suitable for receiving said micro-components, through the alignment of a contact surface of a component with the surface of an assembly location, wherein: • a template substrate is placed facing said substrate surface comprising said assembly locations, said template comprising openings whose shape corresponds to the shape of the largest cross-section of said components taken parallel to the contact surface, said template being placed in an arrangement relative to said carrier substrate so that said openings are aligned with said assembly locations, and at a distance to said carrier which is smaller than the height of the components, said arrangement thereby forming a carrier side and a template side, • said carrier and template, whilst remaining in said arrangement of the template relative to the carrier, are submerged in a liquid, and subsequently • said components are provided to the template side of said arrangement, together with a supply of said liquid directed at the template side, said supply of liquid generating a flow of said liquid from the template side through said openings, said flow guiding the components towards said openings, so that components become inserted in said openings, • the distance between the template and the carrier substrate is large enough to allow a significant liquid flow through the space between the carrier and the template, • said arrangement of the carrier and template is placed horizontally in a tank filled with said liquid, with the template side facing upwards, wherein simultaneously with said supply of liquid, liquid is drained from the tank through one or more outlet openings in said tank. • a template substrate is placed facing said substrate surface comprising said assembly locations, said template comprising openings whose shape corresponds to the shape of the largest cross-section of said components taken parallel to the contact surface, said template being placed in an arrangement relative to said carrier substrate so that said openings are aligned with said assembly locations, and at a distance to said carrier which is smaller than the height of the components, said arrangement thereby forming a carrier side and a template side, • said carrier and template, whilst remaining in said arrangement of the template relative to the carrier, are submerged in a liquid, and subsequently • said components are provided to the template side of said arrangement, together with a supply of said liquid directed at the template side, said supply of liquid generating a flow of said liquid from the template side through said openings, said flow guiding the components towards said openings, so that components become inserted in said openings, • the distance between the template and the carrier substrate is large enough to allow a significant liquid flow through the space between the carrier and the template, • said arrangement of the carrier and template is placed horizontally in a tank filled with said liquid, with the template side facing upwards, wherein simultaneously with said supply of liquid, liquid is drained from the tank through one or more outlet openings in said tank.
