Flux applicator and method for cavity recessed semiconductor chips, has a spring loaded dispensing container

摘要

Flux applicator includes a slide with a lower and upper section. The upper section holds a container (4) and is pulled against the lower section by a spring load. An upper section recess holds a container shaft located in the sliding base plate (2). Front and rear walls of the container are designed round, such that the filling of the cavity (3) begins and ends on the middle axis of the cavity : - The upper part (8b) of the slide is pulled, using a spring force, against the lower part (8a) of the slide in the direction of the base plate so that the container lies on the base plate with a predetermined force. The slide is moved back and forth along a guide rail (9) parallel to the base plate using a pneumatic drive (14) via a rod (15). The slide walls of the container slant such that the contents of the container bank up on the front edge (11) in direction of movement. The container moves over the cavity where the contents are pressed downward into the depression. An independent claim is also included for a device for the application of a liquid substance to an object.
