  • Publication number: 20230102959
    Abstract: A semiconductor package includes a substrate having a top planar surface and a semiconductor die mounted on the top planar surface of the substrate. Bond wires electrically connect the semiconductor die to the substrate. Flow control dams are integrally formed with the top planar surface of the substrate and each flow control dam protrudes from the top planar surface of the substrate at a location proximate to the bond wires. The flow control dams reduce the occurrence of wire sweep in the bond wires electrically connected to the substrate and semiconductor die.

  • Publication number: 20230031117
    Abstract: A system for biological analysis includes a housing, a block assembly within the housing having a sample block and a baseplate, a heated cover and a cover carrier. The sample block receives a sample holder comprising an RFID tag. A first drive mechanism generates relative movement between the sample block and the baseplate along a first axis. A second drive mechanism generates relative movement between the heated cover and the cover carrier along a second axis that is different from the first axis. Based on a first command the first drive mechanism releasably engages the sample block and operates the second drive mechanism to releasably engage the heated cover with the cover carrier. The system also includes first and second RFID antennas that receive RFID data from the sample holder RFID tag that is read by at least one RFID reader.

  • Patent number: 11548846
    Abstract: The present invention discloses a novel method of preparing 8-methyldecanal, a flavor and fragrance material. Specifically, starting from cheap and readily available material 6-chloro-1-hexanol, first, the hydroxyl group was protected with dihydropyran catalyzed by para-toluene sulfonic acid to produce 6-chloro-hexyl tetrahydropyran ether. Then 6-chloro-hexyl tetrahydropyran ether reacted with magnesium turnings to form a Grignard reagent and reacted with 1-bromo-2-methyl-butane under the catalysis of cuprous bromide to give the intermediate 8-methyl-sunny tetrahydropyran ether. Without purification, crude 8-methyl-sunny tetrahydropyran ether was treated under acidic conditions to remove the protecting group to generate 8-methyl-1-decyl alcohol. Finally, 8-methyl decanal was obtained after oxidation with 2, 2, 6, 6-tetramethylpiperidinyloxy.
