The main task of this technology is the development of reliable heat resistant joints on printed circuit boards. The base of technology is spot electrostatic welding-soldering with energy inserting by a special algorithm. (Figures 1,2) Welding head electrodes (3) hold down, with a specified pressure P, electron component lead (2) to a land (5) of a printed circuit board (1). Electrostatic electrode discharge (5) takes place with an energy inserting by a specified algorithm, at the same time an optimal welding-soldering regime is sustained automatically within given limits at the expense of consistant monitoring of energy amount inserted into a joint energy.
