A device for applying fluid to a substrate which includes a head member having first and second opposed portions adapted for being fixedly positioned relative to each other. The device is particularly suited for treating a substrate as the substrate moves between the first and second portions. Each portion may in turn include a first channel located at a predetermined distance from the substrate for having a first fluid impinge on the substrate at a first velocity. Additionally, each portion may include a weir adjacent the first channel for having fluid pass thereover at an accelerated rate and thus at a greater velocity than the first fluid, this weir being located at a lesser distance than the first channel. Fluid inlet means is coupled to the respective portions to provide the fluid thereto at desired velocities. Significantly, a fluid blocking means (e.g., an elongated bar) is also included as part of the structure for maintaining the fluids at pre-established levels.

Fluid treatment device

A method and device are provided for connecting a triaxial or coaxial cable to a substrate by surface mount technology wherein the substrate has a plurality of contact pads located on the surface thereof. The connector includes a signal wire connector element connected to the signal wire of the cable and a drain wire connector element connected to each of the drain wires of the cable. The connection also includes resilient connector element, including a flexible circuit having a plurality of spaced electrical conducting lines thereon. One set of lines is for connection to the signal wires of the cable and the other set for connection to the drain wire(s) of the cable. The opposite ends of the signal line and drain line of the flexible circuit element are connected to electrical connection pads on the substrate to provide signal and drain connections between the cable and the substrate. A support element is configured and positioned to mount a plurality of the connectors on the substrate with the resilient element being resiliently urged into contact with the electrical connection pads on the substrate.

Method and apparatus for connecting cable to the surface of printed

A method and apparatus for selectively spray etching an epoxy encapsulated chip which is mounted to a chip carrier without damage to the chip, the chip carrier or other closely mounted chips. The apparatus includes a diaphragm which can be raised and lowered to direct the flow of etchant solution at the encapsulating material located alongside and under the chip. The encapsulating material is removed from the chip without removing the chip from the chip carrier.
