For example, devices and systems disclosed herein may include reusable cases for storing dedicated column bed supports when the column bed supports are not in use. Such cases may include one or more dividers and inserts configured to fit column bed supports, and may be designed and built specifically to ensure efficient, secure storage of column bed supports while minimizing risk of damaging or contaminating them. Methods disclosed herein may include performing a particular chromatography operation in a column, removing the column bed supports from the column, storing the column bed supports in a column bed support storage case, and installing another set of column bed supports in the column for another chromatography operation.

Abstract: A method for manufacturing an electronic device includes placing a plurality of components on a printed wiring board (204), detecting a defect in a component (210) and, in response, producing a defect indication including a defect location on the printed wiring board. Subsequently, additional components are placed on the printed wiring board (220) but placement of all additional components having a location which has a predetermined relation with the defect location is suspended. The defective printed wiring board may then be repaired by a technician who subsequently places the additional components over the defect location. This reduces the need to apply a large amount of heat to the printed wiring board to remove subsequently placed components such as radio frequency shields. This further reduces the possibility of additional defects occurring during repair.

Abstract: A method for making a heat exchanger assembly (10) includes inserting tubes (20) through fin holes (32) in heat exchanger fins (30) and headers (40, 42) to form a bundle (50), and expanding the tubes (20) forming an interference fit with the heat exchanger fins (30). The bundle (50) is inserted into a housing (60) open at both end; (67, 68) and having a wall (62) surrounding the headers (40, 42) with inlet and outlet lines (64, 66) in the wall (62), and sealing the wall (62) of the housing (60) to the first and second headers (40, 42) with the inlet and outlet lines (64, 66) disposed between the headers (40, 42). A plurality of mandrel heads (70) are inserted through the open ends (67, 68) of the housing (60) into the tubes (20) expanding the tubes (20) into the headers (40, 42) to form a sealed joint between the tubes (20) and the headers (40, 42).

Abstract: Accuracy of a circuit assembly process (100) is determined by capturing an image (306, 1008) of an assembly formed on a substrate by the circuit assembly process (100), calculating coverage (310, 1012, 1024) of the assembly from the image, and comparing the coverage (312, 1016, 1026) to a threshold.

Abstract: An apparatus (200) and method are provided for testing a nozzle of a pick-and-place system (100). The apparatus (200) includes a reservoir (206) configured to carry a fluid, a membrane (204) covering an opening of the reservoir (206), and a reservoir pressure sensor. The apparatus may further include a processor (118) coupled to the reservoir pressure sensor (208) and an output device (116) coupled to the processor (118). The nozzle (104) is positioned to contact and displace the membrane (204), thus changing the pressure of the fluid within the reservoir (206). The reservoir pressure sensor (208) senses pressure changes within the reservoir (206) and generates a signal that varies in response to the displacement of the membrane. The signal is compared to a predetermined signal to detect whether the nozzle has the proper position, the proper alignment, sufficient vacuum, and other errors affecting pick-and-place systems.

Abstract: A carrier/insertion apparatus that has a U channel handle is improved to comprise an insertion portion, a stabilizer plate, and a deflector portion. The substrate that the carrier/insertion apparatus is mounted on comprises a carrier/insertion apparatus interface region that allows the carrier/insertion apparatus to mate thereto. As the carrier/insertion apparatus is slid into place, the deflector portion deflects the substrate a predetermined distance such that the carrier/insertion apparatus can be snapped into place. This arrangement allows for the carrier/insertion apparatus to be mounted on to a substrate without the use of mechanical hardware.
