Abstract

Often the arrangement of conductive lines and lands on the surface of a printed circuit board is such that insufficient room remains for satisfactorily mounting a transistor or transistors. This is a technique of cementing an insulating transistor cap to the board and inserting the inverted transistor in it. Since the transistor cap is made of insulating material, no electrical problems result, yet adequate support is provided for the transistor. The transistor leads are then connected to the plated-through holes in the lands.
