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. <EOS>
