SMOX® Surface Mount Test

Surface Mount Applications

Surface-Mount Oxley (SMOX) Test-Point is available Taped and Reeled,
with a compatible mating socket and is suitable for a range of applications.

Due to the unique nature of the SMOX Connection System, it represents the
only Surface Mount Test Point available on the market with a specially
designed socket for easy low contact resistance and gentle detachment; the
applications and potential uses are limitless.

Requiring a minimum pad size of only two millimetres (0.080”), and being a
singlepole device, the SMOX can be placed accurately by any Pick and
Place machine in even the most congested designs. The socket is normally
used with the recommended PTFE Insulated Sleeve, (diameter 3.2 mm/

0.128”), but for those very close pitch designers, this can be replaced with
alternative insulation techniques.

Detecting and localising board faults is an obvious application, where the
ability to quickly and individually identify faulty components, cracked solder
joints or short circuits can save time of testing via an edge mounted
connector, or under a microscope.

On thick multilayered boards, where complex track designs can lead to very
expensive PCB’s, the benefits of quickly and effectively identifying and
repairing any faulty populated PCB can be easily recognised.

The ability to monitor waveform characteristics and determine the
performance of a circuit with variable components is vital, and not just in a
test laboratory. Where exact frequency output is required, a certain
waveform is needed or the ability to manually set the characteristics of each
production board manufactured; the inclusion of SMOX Test Points fulfils
that requirement.

SMOX® Surface Mount Test

Key Characteristics

Gold plated SMOX Test Point for low contact resistance and durability.
SMOX Connector Systems to reduce the risk of accidental damage to the

PCB. Can be used on any Pick and Place machine using vacuum nozzles.
Square or round solder pads can be used, with a minimum pad size of 2 mm

diameter.

Sockets are gently

detached when moved

beyond an angle of 30°

from vertical.

Packaging

The SMOX/060/B1LP.R3K Test Point is available on Tape and Reel, to
enable placement on to PCB’s by a variety of pick and Place machines. The
plastic reels are an industry standard 7” diameter and the R3K extension
denotes 3,000 components in a specially designed carrier tape.

The SMOX/060/B1-R2K test point is available on Tape and Reel, to enable
placement on to PCB’s by a variety of pick and Place machines. The plastic
reels are an industry standard 7” diameter and the .R2K extension denotes
2,000 components in a specially designed carrier tape.

The solid flat bottomed pocket ensures the component is in the correct
vertical position when the heat sealing backing tape is peeled off. 100%
visual inspection by camera during population of the tape ensures no
components are heat sealed in place in the wrong position, or that empty
pockets can be sealed.

For customers requiring the SMOX Socket to be supplied assembled, a
standard product is available on 15” of cable, with differing lengths possible
where demand exists.

KINKY PIN Plated Through

Hole (PTH) Connectors

Application

• Self retaining compliant pin for plated
through holes in multilayer printed
circuit boards.

Kinky Pins

Kinky Pins were designed specifically to meet the demands of plated
through hole (PTH) technology introduced in printed circuit boards. They
tend to be used with flexi-circuit termination and as solder terminals,
connectors and in multiway pin arrays.

They use a unique kinked retention mechanism which gives a fit in the PTH
that is unsurpassed. The kinked leg provides a tight non-aggressive spring
loaded fit whilst the straight leg ensures the pin is kept perpendicular to the
PCB prior to soldering.

This Kinky Pin mechanism gives an additional benefit which is a key part
of its operation. The slotted design induces wicking of the solder up into the
kink and up to the flange which means that the solder joint is solid and free
of air pockets. This reduces the possibility of dry joints developing and the
life of the solder joint is therefore increased. In our opinion and that of our
customers, there is no better PTH solder-in terminal!

The Kinky Pin range is comprehensive and our in-house high precision
machining capabilities mean that we have the ability to manufacture
bespoke versions on request. Standard finishes are tin lead and gold;
other finishes are available on request.

Snale Pins

The use of Snale Pins has been widely established in the commercial and
military electronics market worldwide as the definitive terminal pin for use
with non-plated through hole PCB’s and chassis.

The knurled and barbed retention mechanism gives a low insertion force,
high retention and non-rotation fit ensuring rigidity with ease of assembly.
The snale Pin range is available in a variety of lengths and diameters to suit
applications such as multiway pin headers on aircraft engine control
systems, as pins in connectors and lead-through terminals and solder posts
on flow meters.

They are available in standard Tin Lead and Gold finishes with others
available on request. Bespoke styles are also available due to our in-house
high precision machining capabilities.
