When mounting pinless electronic components on the conductor path side of a printed circuit card, the components are oriented in a predetermined manner, depending on the desired orientation at the mounting site, in component trays from which the components are transferred to the printed circuit card by means of a manually operated suction device. On the conductor path side of the printed circuit card, an adhesive material has previously been applied to the intended mounting sites of the components, the suction force of the suction device being set at a lower value than the adhesive force of the adhesive material. In addition to a number of component trays, a mounting table with a rotatable holder for the printed circuit cards, a program-controlled indicator system for indicating the relevant trays and mounting sites, and a suction device for manually transferring the components from the trays to the printed circuit card, the device according to the present invention has been provided with a surface profiling, preferably in the form of grooves, adapted to determine the intended component orientation and to intercept said components. The device also has a movable wrist support ruler for quick and accurate alignment of the components with respect to the intended mounting sites, and in the suction line of the suction device, a pressure sensing element may be provided for sensing when a component has been placed on the printed circuit card. |
