Abstract: A method for mounting electronic parts on a printed circuit board by applying an adhesive to a printed board at predetermined positions is provided. A droplet of an acryl-modified resin emulsion adhesive in a predetermined volume is ejected from a nozzle to said board at each of said positions, the adhesive is dried to remove water therefrom to ensure mounting of said parts on said binder and a solder is applied to said adhesive areas. The advantage is that an exact amount of adhesive for retaining each part on the board is obtained by each single droplet and in addition the nozzle is non-contactive to the board.

Abstract: An electronic circuit element capable of positively and stably accomplishing its provisional fixing on a printed circuit board substantially free of any trouble and being readily taken out or extracted for the mounting on a printed circuit board, irrespective of a manner of holding of the circuit element prior to the extraction. The electronic circuit element includes an element body and an adhesive or polymeric layer deposited on the element body. The polymeric layer is arranged on a surface of the element body opposite to a printed circuit board on which the circuit element is to be mounted. The polymeric layer is formed of a material exhibiting adhesion when it is heated to a temperature of about 80.degree. C.
