Abstract
Methods, systems, devices, and products for manufacturing an electrical assembly, such as a completed downhole circuit board, for use in well logging. Methods include attaching an electrical component to a printed circuit board by mechanically fastening the electrical component to the printed circuit board. Methods may include using a laser to attach a plurality of legs to contact surfaces. Methods may include applying light from the laser to a material of the printed circuit board to produce heat, including mitigating reflection of the light from the material. Methods include forming a connection between a first electrical component of the electrical assembly and a second electrical component of the electrical assembly by causing heating of an additive manufacturing material by applying light from a laser. The connection may be at least one of: i) an electrical connection; ii) a structural connection; iii) an electrical insulation.
