Abstract
A jet head box for a semiconductor substrate and nozzle plate containing fluid jet actuators. The jet head box includes an elongate substantially rigid body having a first surface and a second surface opposite the first surface. The body also includes a first recessed portion defining a substrate pocket area in the first surface thereof. An elongate slot extends through the body from the second surface to the first surface in the substrate pocket area. An encapsulant dam is provided adjacent at least one end thereof. A shelf is adjacent the encapsulant dam. The jet head box provides a low cost construction for simple miniature fluid jetting devices.
