Cisco Introduces a New Mobil IP
Cisco Systems, Inc. has announced availability of new Mobile IP
functionality called Cisco Mobile Networks. Mobile IP, as specified by the
Internet Engineering Task Force (IETF), enables an IP device to roam across
networks and geographies while remaining constantly connected to the network or
the Internet as if it is attached to its home location all the time using the
same IP address. With the Mobile
Networks functionality, a Cisco router along with its entire network of
connected IP devices can now roam seamlessly across network boundaries and
connection types.
Mobile Networks is independent of the physical layer and operates transparently over cellular, satellite and other types of communications networks. A mobile LAN powered by Cisco Mobile Networks supports an "always on" connection to the Internet, enabling end users connected to the LAN to stay fully functional at all times during long periods of transit. For example, an airplane with a router running Cisco Mobile IP with the Cisco Mobile Networks functionality can fly around the world with all passengers continuously connected to the Internet. The passengers connect their laptops, personal digital assistants, or cell phones to the router on the airplane using traditional LAN technologies such as Ethernet or 802.11b. No special "mobility enabled" devices are required as the network is enabling the mobility.

The NC-SMQ 81 Sn-Bi-Ag alloy solder
paste is claimed to be the only commercially available robust No-Clean,
Halide-free solder paste designed for thermally sensitive assembly processes
using the eutectic Sn-Bi-Ag alloy. In a
typical reflow soldering profile (forced convection system), its maximum peak
temperature is 170°C (in order to pass SIR) with a maximum temperature of
195°C. The solder paste meets J-STD-004
and -005 criteria, as well as Bellcore, ANSI/IPC-SF-818/SP-819 and Mil-P-28809
specifications
Cobar's XM-5 series no-clean solder
paste utilizes the company's new polymer system, which is claimed to give the paste
unparalleled thermal stability, even under the demanding conditions and high
temperatures associated with lead-free soldering. The formulation is extremely clean, offering excellent wetting
and soldering performance while leaving minimal residue, and resists
collecting/condensing on reflow oven internal surfaces. XM-5 wets evenly and coalesces uniformly on
solder connections, minimizing tombstoning effects associated with today's
ever-smaller passive electronic components.
The paste can be printed at high speeds under very low pressures with
zero print defects.
