According to David Schedin, product manager, AVX's
8069 series shield lock connectors allow design and production
engineers to install and remove RF shielding without the need for
labor-intensive soldering or resoldering. |
Designated the 8069 Series, the new connector family is specifically
designed to lock RF shielding cans to the printed circuit board (PCB).
According to the company, the new series extends the AVX connector range
while addressing the needs of design and production engineers who need
to access components housed under an RF shield. Applications include
cellular phones, notebook computers, PDAs, and other portable electronic
devices that require shielding.
"Traditionally, RF shielding cans have been hard-soldered to the
PCB during assembly, often as a secondary soldering process.
This can mean that
any rework is an expensive and time-consuming process," explains
David Schedin, AVX product manager. "The Series 8069 connector is
an SMT shield clip that will lock the can in place, which avoids the
secondary soldering process and allows the can to be removed and refitted
without damage to the PCB," he continues.
According to Mr. Schedin,
the shield lock clips utilize spring contact technology to mechanically
and electrically connect the RF shield to
the PCB. "Certainly the automation and control associated with modern
pick and place/reflow processing has proven to outperform competing manual
methods," he says. "This advantage manifests itself in lower
manufacturing costs and improved reliability."
The SMT shield clips
are stamped and formed from a Phosphor Bronze material to provide electrical
conductivity and spring-like properties. The components
are also plated with tin. "This is done to make the contact compatible
with pick-and-place reflow solder manufacturing processes," Mr.
Schedin explains.
The connectors come in standard heights of 1.80 mm and
3.00 mm and are available in tape-and-reel packaging of 3,000 pieces
per reel. In addition,
they have a current rating of 0.5 A, a voltage rating of 5.0 V, and
will accept 0.20-mm thick metal cans.
