The Radioisotope Fume Hood is engineered to meet the strict requirements
for lab work involving radiochemicals. The
hood is constructed with a welded one
piece seamless type 304 stainless steel
interior fume chamber with all corners
coved for easy cleaning. The work surface
is welded to the fume chamber liner and is
reinforced to support weight loads associated to isotope work such as lead barriers
and equipment. LED lighting and vertical
slide tempered glass sash are standard
features. These fume hoods are offered in
48, 60, and 72 in. widths and can be outfitted with a wide selection of accessories
including service fixtures, electrical service
options, cabinets/tables and suitable exhaust blowers to safely remove hazardous
fumes or particulates.
Ironwood Electronics has introduced a new high performance elastomer socket
for 0.65 mm pitch BGA package. The SG25-BGA-2045 socket is designed for a
11 mm x11 mm package size and operates at bandwidths up to 52 GHz with less
than 1dB of insertion loss (GSSG configuration). The contact resistance is typically 20
milliohms per pin. Network analyzer reflection measurements for the G-S-S-G case
were taken with all except the pins under consideration terminated into 50 Ohms. The
socket is mounted using supplied hardware on the target PCB with no soldering and
uses smallest footprint in the industry. The smallest footprint allows inductors, resistors,
and decoupling capacitors to be placed very close to the device for impedance tuning.
The socket also incorporates a simple swivel hardware installation method so that IC’s
can be changed out quickly.
The SG25-BGA-2045 sockets are constructed with high performance and low inductance elastomer contactor. The temperature range is –35 ºC to +100 ºC. The pin
self-inductance is 0.06 nH and mutual inductance of 0.019 nH. Capacitance to ground
is 0.129 pF and mutual capacitance is 0.017pF. Current capacity is
2 amps per pin.
