Abstract: A flow sensor includes a flow tube in a form of a tube and a support cast around the flow tube. The support clamps the flow tube and the flow tube extends through the support. The flow sensor is formed by placing the flow tube in a tube cavity of a casting mold and pouring or injecting a liquid resin into a support cavity of the casting mold. The support is formed around the flow tube from solidifying the liquid resin in the support cavity of the casting mold. A temperature of the casting mold during formation of the support does not exceed a threshold temperature to avoid deformation of the flow tube. The flow sensor can also include at least one memory chip that stores calibration information associated with the flow sensor and connectors that allows a controller to read the calibration information from the memory chip.

Abstract: A flow measurement system includes two or more flow sensors that may operate simultaneously and a plurality of connected flow paths for flow of fluids. Each flow sensor is positioned along a different flow path of the plurality of connected flow paths and includes at least one flow tube and a support that clamps the flow tube. The flow tube of each flow sensor has a different resonant frequency so that cross-talk between the flow sensors can be reduced or eliminated. In some embodiments, the flow tube of each flow sensor has a different tube length, wall thickness, material, and/or weight. The flow measurement system can also include one or more pumps for pumping fluid into the flow sensors and a dampener arranged between a pump and a corresponding flow sensor for mitigating interference on the flow sensor from operation of the pump.

Abstract: An improved contact probe pin for wafer probing apparatus including an elongated metal conductor having a connector (or proximal) end, a center or medial section coated with an elastic material, and a contact pad engaging tip end. At least a portion of the center section of the probe pin is coated with a poorly conductive, but highly elastic material so as to enhance its flex characteristics. The coating may uniformly cover a portion of the center section of the probe pin or it may take on a predetermined pattern or shape. The coating may also unevenly cover a portion of the center section of the probe pin. The coating is selected such that it augments or enhances the resiliency of the pin and causes it to have a predetermined stress-strain profile with vertical (or Z-axis) displacement, and thus enables it to have predetermined probe pin tip contact force characteristics.

Abstract: An improved contact probe pin for wafer probing apparatus including an elongated metal conductor having a connector (or proximal) end, a center or medial section coated with an elastic material, and a contact pad engaging tip end. More specifically, at least a portion of the center section of the probe pin is coated with a poorly conductive, but highly elastic metal so as to enhance the flex characteristics of the probe pin. The coating may uniformly cover a portion of the center section of the probe pin or it may take on a predetermined pattern or shape. The coating may also, in some applications, unevenly cover a portion of the center section of the probe pin. The coating is selected such that it augments or enhances the resiliency of the pin and causes it to have a predetermined stress-strain profile with vertical (or Z-axis) displacement, and thus enables it to have predetermined probe pin tip contact force characteristics.
