Thanks to the highly automated precision machining division
at the Preci-Dip production plant, most Preci-Dip products come with high
quality machined contacts for additional safety and durability.
Machined precision contacts
Preci-Dip's contact technology for receptacles uses three, four or six finger
clips made of CuBe and housed in a machined brass sleeve. Platings can be
different for both parts, e.g. tin for the sleeve, gold for the clip. Contact
clips are produced on modern, high speed precision stamping machines and inserted
- after plating of both parts - into the sleeve on fully automatic assembly
lines. Receptacles made by Preci-Dip are of extremely good reliability and
have excellent performances with respect to shock and vibration, number of
matings, contact resistance, etc. One of the most important features, however,
is the closed design of the sleeve which makes it absolutely safe against
flux wicking during the soldering process.
Insertion diameter and contact point
Insertion diameter and contact point of the receptacles
may vary depending on contact type.
These relevant values are normally indicated on each catalog drawing representing
a receptacle:
- insertable pin diameter (0.40-0.65 mm) or rectangle (0.25 x 0.45 mm) is
shown on top of part
- distance between contact point and upper edge of receptacle (2.4 mm) is
shown on left side of part.
Male contacts
Male contacts have cylindrical, machined pins. In comparison to pins with
square or rectangular section, this provides for smoother insertion/extraction
with more constant forces, longer life and higher reliability. The terminations
of machined contacts are rugged and accurately positioned, bending of leads
by inadvertance is almost excluded which makes handling very easy.
Interconnect components
Machined pins are ideally suited for all kinds of board-to-board interconnecting
applications. Their ruggedness and precision are mayor advantages when reliability
and sturdiness of the mechanical assembly are major requirements. Interconnect
contacts are available in a variety of different lengths to suit a maximum
number of applications. They are mostly fitted to single or double row strip
insulators but they are also available on dual-in- line or other body styles.
The fact of these contacts being machined allows to manufacture customer specific
lengths with no or very little tooling cost.
Insulator bodies
Precision injection molded insulator bodies are made of temperature resistant
thermoplastic material, to withstand soldering heat and climatic requirements.
All the plastic materials used on Preci-Dip products are UL 94-VO rated.
Contact strips have a notched design. The insulators are thus
easy to cut to any length - in most cases without any loss of contact.
Carriers
Disposable insulators made of recycled plastic material with cart" pins
and plugged-on contacts are used on Preci-Dip's unique carrier sockets and
strips. These carriers are rugged and have the same rigidity and precision
as the standard sockets and strips. In comparison to flexible care` solution,
Preci-Dip carriers are as easy to handle as normal precision sockets and strips.
All styles of insulator bodies including PGAs can be equipped for Carrier
applications.
Products with stamped contacts
Some Preci-Dip product lines come with stamped contact versions Please
refer to respective product pages for detailed information.
