5. Removable Lid Spring
Pin Socket for QFN28

6. Clean Room
Cabinet Oven

Ironwood Electronics introduced
a QFN socket addressing highperformance requirements for
custom-sized devices called the
CBT-QFN-7071. The contactor
is a stamped spring pin with
14.5 gram actuation force per
pin and a cycle life of 100,000
insertions. The self-inductance
of the contactor is 0.98 nH, with
an insertion loss of less than 1
dB at 31.7 GHz and a capacitance
0.067pF. The current capacity of
each contactor is 4 amps. Socket
temperature range is -55C to
+180C. Socket also features an
IC guide pocket inside the top
pin guide for precise QFN edge
alignment.

Grieve's No.797 is a 260°F
(127°C), clean room cabinet
oven that can be used for drying
coating on printed circuit boards.
Workspace dimensions of this
oven measure 36 " W x 36 " D
x 39 " H. 20 KW installed in
Incoloy sheathed tubular heating
elements, while a 1000 CFM,
1-1/2 HP recirculating blower
provides horizontal airflow to
the workload. This oven features
4 " insulated walls, Type 304, 2B
finish stainless steel interior with
continuously back-welded seams
and an exterior finished with
white epoxy paint. Oven features
include a #4 brushed stainless
steel door cover and control panel
face.

7. Low Profile Mid-Plane 8. FSW signal and
RJ45 Connectors
spectrum analyzer
upgraded
Stewart Connector introduced a
series of low-profile mid-plane
RJ45 connectors. The Mid-Plane
RJ45 design allows the connector
to straddle the board edge, and
utilize space above and below the
printed circuit board, compared
to traditional RJ45 connectors
that are only designed to mount
above the printed circuit board.
The Mid-Plane connectors offer
a high-speed solution for a wide
array of IoT applications, including
servers/switches, video game
systems, and portable storage
devices. They RJ45 connectors
support 1 and 2.5G data rates
and 100 MHz transmission
frequencies.

With the R&S FSW-B8001
option, the R&S FSW high-end
signal and spectrum analyzer
now supports an 8.3 GHz internal
analysis bandwidth, offering
dynamic range and sensitivity.
Design engineers developing
the latest radar and wireless
communications technologies
as well as future satellite
systems will benefit from the
extended bandwidth available
in a one-box solution. Covering
an input frequency range of up
to 90 GHz, the instrument offers
dynamic range and sensitivity,
precision and EVM performance.
Applications for the R&S FSW
include pulse measurements of
A&D radar systems, satellite
payload testing and amplifier predistortion tests.
