摘要:
A direct chip attach module (DCAM) 10, comprises of one or more electronic components 30, electrically bonded to a printed circuit 40, on a substrate 20. The DCAM 10, is bonded to an electronic circuit assembly by connection pads 50, formed on the edge of the DCAM substrate 10. This enables easy visual inspection of solder joints between the DCAM and the assembly.DCAM substrates 10, are initially formed in a panel form 70, and vias 50, are drilled and filled with electrically conductive media 55, at predetermined connection points. The DCAM 10, is then excised from the parent panel 70, and the cut vias provide connection pads 55, along the edge of the substrate 10.

摘要:
Compounds of the general formula (I) are inhibitors of the reuptake of norepinephrine. As such, they may be useful for the treatment of disorders of the central and/or peripheral nervous system.
摘要:
The present invention is a method for cleaning a process chamber without damaging the process kit by coating the process kit with another consumable material that protects the process kit during the etch that removes buildup from the processing chamber. First, a polysilicon layer is deposited on at least one inner surface of the processing chamber. Next, a silicon nitride layer deposition is performed on at least one semiconductor substrate in the processing chamber. The semiconductor substrate having said nitride layer thereon is then removed from the processing chamber. An etch is then performed to remove the nitride layer buildup from the inner surface of the processing chamber that has the polysilicon layer thereon.
