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.
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°

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.
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.
The Snaplox® name has firmly established itself in the world electronics
market. The award winning design has yielded use in a vast range of
applications in the commercial and military electronics world. Applications
which use them include towed sonar arrays and rolling stock electronics
equipment.

reducing the risk of board damage. This is due to the unique ball and socket
arrangement which provides 8 points of low resistance contact through a 60°
connection angle. Beyond this 60° the socket disconnects with ease
preventing stress to the pin and board.
The standard finishes are palladium or Gold plated pin and PTFE insulated
Silver plated socket to give a robust, long life, low contact resistance test
point system. Other finishes are available on request.
They are available with a range of PCB (surface mount, Kinky Pin and
Snale) and chassis mounting (Barb Cone-Lock) retention mechanisms to
suit most applications and bespoke styles can be manufactured as needed
due to our in-house, high precision machining capabilities.
Oxley Developments designed the Barb Cone Lock
constructed from PTFE and have an elastic property which allows the barbed
metal spill to lock itself in place by gently expanding the PTFE underneath
the chassis during insertion. This ensures a long life, stable fixing in the
chassis which is a fundamental part of the product’s success.
The product has seen use in a whole host of applications from the military,
nuclear and space industries to the medical and telecommunications
industries. There is a vast range of types and styles to suit a variety of hole
sizes and chassis thicknesses. There are also the "CEEL" high sealing
versions for use in applications involving vacuums and differential pressures.
The spills are precision turned, high specification brass material with a silver
plating finish as standard. Other finishes are available on request.
We also have the capability to manufacture Barb Cone Locks
of exotic metals for thermocouple applications.

card rack systems.
BARB CONE LOCK
Plugs and Sockets
®
Barb Cone Lock® Plugs and Sockets
Using the same technology as the Barb Cone Lock® Insulated Terminals,
this product range utilise High Dispersion Grade PTFE for insulation and
reliability.
The range includes chassis mounting plugs and sockets, line plugs and
sockets and multiway edge mounting sockets all in a range of diameters from
0.5 mm to 4 mm with current ratings from 1 to 5 Amps. Typical applications
are for test equipment and card rack systems in the military, aerospace and
nuclear industries and for high voltage applications up to 2 kV.
The simple assembly provides a product with high insulation resistance and
low contact resistance.
Standard finishes are Gold flash on a Silver undercoat for the plugs, and
Silver on the sockets helping to maintain a low contact resistance
performance over many mating cycles. Other finishes are available on
request.
1. Thread the connecting wire through the insulating sleeve.
2. Solder the wire into the hole on the probe.
3. Assemble the sleeve and probe with the appropriate insertion tools or by
hand.
1. Ensure the holes are within tolerance and deburred.
2. Place the bush into the hole.Support the chassis underneath throughout
this operation.
3. Using the appropriate assembly tool, slowly press the socket tube into
the bush until it is just below the top surface of the bush. Support the
chassis underneath throughout this operation.
Oxley Barb Cone Lock self locking plugs and sockets are designed to take
advantage of the outstanding electrical and physical properties of high
dispersion grade PTFE (polytetrafluorethylene).
The socket contact is slit longitudinally to exploit the inherent elastic of the
surrounding PTFE, thus providing the necessary retention and low contact
resistance even after repeated insertions.
The chassis mounted connectors are assembled by first inserting the PTFE
bush into the mounting hole and then slowly, but firmly, inserting the contact
spill through the bush until a positive action firmly locks the assembly in
place.
The flying connector is assembled by first threading the PTFE sleeve on to
the connecting wire, then soldering the wire in the solder bucket, before
pressing home the sleeve onto the spill.
