摘要:
The present invention relates to a process comprising the steps of reacting in the presence of a hydrosilylation catalyst, a first reaction mixture comprising a free radical reactive compound and a silicon containing compound to form a silicon substituted glyceryl (meth)acrylate.
摘要:
An integrated void-free process has been developed for attaching a solder bumped chip to a substrate. The chip is first dipped in a tacky thermosettable flux, and the chip is mounted on the substrate. An underfill is dispensed along the edge of the chip The device is then sent into the reflow furnace to complete the underfilling (which optionally can be completed before reflow), solder reflowing and underfill curing. The flux also acts as a physical barrier minimizing, if not eliminating, the interference of filler on solder wetting and resulting metallurgical joints formed between the solder and the bond pads. The process allows for the integration of a void free conventional capillary flow underfilling process and a pre-deposited fluxing underfilling process by using a tacky thermosettable flux, avoiding the problems associated with each of the individual processes and requiring less time for the overall process.

Various embodiments disclosed relate to analyte sensor configurations. The present disclosure can include planar analyte sensors or coaxial analyte sensors. The planar analyte sensors can include one or more insulating and conductive layers and a substrate layered on each other. The coaxial analyte sensors can include one or more co-extruded wire electrodes with a substrate. The continuous analyte monitoring systems discussed herein can be configured to monitor one or more analytes to provide predictive and real-time health data and benefits.
摘要:
New polymer electrolytes were prepared by in situ cross-linking of allyl functional polymers based on hydrosilation reaction using a multifunctional silane cross-linker and an organoplatinum catalyst. The new cross-linked electrolytes are insoluble in organic solvent and show much better mechanical strength. In addition, the processability of the polymer electrolyte is maintained since the casting is finished well before the gel formation.
