Picoflex Vertical SMT headers from Molex can withstand reflow at temperatures up to 260C

Picoflex Vertical SMT headers from Molex are specifically designed for compatibility with the latest lead-free soldering processes and can withstand reflow at temperatures up to 260C. The headers, which are rated at 2.4A per circuit at up to 250V, have a pitch of 1.27mm and are available in a choice of standard and low-profile versions.

The insulant used in the new Picoflex headers is fully compatible with the stringent demands of the glow-wire test prescribed by IEC60335 and is self-extinguishing in line with the requirements of UL94V-0.

The headers are therefore an ideal and cost-effective choice for use in a wide range of applications - including white goods, medical, and industrial equipment - where suitability for unattended operation is essential.

Fully compatible with standard connectors in the Picoflex range, the new headers can be supplied with tin or gold-plated contacts, and are available in versions with between 4 and 26 circuits.

Other options include printed circuit board pegs for positive location, and a choice of tube or tape-on-reel packaging.

When used in conjunction with Molex Picoflex discrete wire connectors, which incorporate finger tabs for easy tool-free mating, the new headers have a maximum mating force of 1.7N for tin-plated types, and 1.1N for gold-plated versions.

They are designed for applications requiring occasional mating and unmating and have a minimum durability of 30 cycles for tin and 100 cycles for gold.

The operating temperature range for Molex Picoflex headers is -40C to +105C.

Used with Picoflex discrete wire connectors, they have a maximum contact resistance of 15 milliohm, a di-electric withstand voltage of 750V AC and a minimum insulation resistance of 1,000Mohm.

Onanon’s innovations in compliant pin technology are made possible by its highly automated, close-tolerance milling manufacture

Onanon has released smooth sliding, fast holding press-fit compliant pin connectors. Compliant pin technology has stood the test of time by providing press-fit connections that withstand thermal shock, vibration and humidity. Onanon has improved this 20-year old technology so that the compliant pins slide smoothly into plated thru-holes, a major breakthrough in this tried and tested green technology that makes it even more cost-effective and environmentally friendly.
These devices can be used in the harshest environments and in the most delicate devices.

They are solderless and meet RoHS standards.

Onanon compliant pin connectors can be selected from a quick order catalogue or custom made.

Onanon’s innovations in compliant pin technology are made possible by its highly automated, close-tolerance milling manufacture.

‘In the prior technology, an oval ‘eye of the needle’ hole was punched into a pin’.

‘When this pin is inserted into a plated thru-hole, the ‘eye of the needle’ compressed with a spring force that held the pin snug’, said Dennis Johnson, CEO of Onanon.

‘Now, by precisely engineering the curvature of the hole and pin, we can guarantee that the contact force is more than sufficient to maintain contact in the harshest environments, but not so great as to produce excessive insertion force’.

Limiting the insertion force allows easy insertion of connectors with a large number of pins.

It also eliminates particulate debris from being scraped from the plated thru-hole and increases the number of reinsertion cycles to over a thousand.

The rapid increase in chip performance, density, mixed signal level type and frequency has placed increasing demands on printed circuit board (PCB) manufacturers.

Rapid advances in technology leave a trail of obsolescence.

Redesigning and testing a new board to stay on the cutting edge can be expensive.

Onanon compliant pin technology simplifies and reduces the cost of PCB manufacture.

The devices remove the time, cost and thermal stress of soldering.

All the problems associated with solder such as residue, bridging, cracked or cold solder joints are also eliminated.

Connectors can be manufactured with a PCB platform.

These connectors can be part of an interconnection or plug-in modules designed to modify a board’s function.

Both plug-ins and interconnection platforms have been designed and engineered using only terminating resistors or decoupling capacitors, while other platforms have hosted more complex configurations using microcontroller or analogue chips.

Onanon’s compliant pin products provide production flexibility to manufacturers.

Mass termination of connectors is common in the telecommunications industry.

A press can inserts a connector with up to a thousand pins.

Pin-stitching systems can apply discreet reeled pins one at a time.

This latter process has the advantage of a flexible insertion pattern that can change to offer different options in the same PCB.

Onanon delivers custom headers according to the customer’s specification.

These headers can be automatically inserted at the factory or manually replaced in the field using ordinary tools.

Customised connector products can be engineered and manufactured with any pin size, shape or pattern and placed in a variety of insulators.

Since there are no set-up charges, modification can be made on connectors with just-in-time delivery to accommodate new board innovations.

Onanon assembles custom connectors with a fully automated process.

Pins or contacts are installed to a precise depth into machined insulators.

Straight and secure installation in the plastic, ceramic or ferrite substrate is insured.

The finished product is human inspected by real-time x-ray analysis.

These interconnections can deliver DC to 10GHz, with pin-to-pin capacitance as low as 1pF, inductances as low as 2nH and connection resistance less than 10mohm.

The cost-effectiveness and rugged ability of these pins allows them to be used in the harshest conditions such as aerospace, military and automotive industries.

They are also able to perform in the most delicate devices such as medical instruments and mobile phones.

The system offers three different tail lengths on the through-hole shields, kinked tails and SMT versions.

9175 connectors can be used for connecting two or three wires between PCBs in high-volume consumer market applications

TTI has added AVX’ 9175 connector to its portfolio, allowing users to easily connect individual wires to a single row of contacts using IDC technology. Currently available as two and three-way IDC connectors, the device is both low-profile (3.45mm) with a small PCB footprint, saving precious space on PCBs

A dedicated single-wire insertion hand tool allows for quick and easy assembly.

Before assembly, 9175 series connectors are surface mounted to the PCB.

Using the hand tool, 26 or 28 AWG solid/stranded wires are inserted into the contact slot.

This process cuts the insulation and enables the individual conductors of the wire to form a homogeneous joint.

The shape of the moulding forms a restraint to the wire when fully inserted in the contact.

Contact material is phosphor bronze, with five re-terminations achievable for each individual contact.

The devices offer a current rating of 1A continuous through all contacts at 25C (ambient), with a voltage rating of 125V.

The components feature an operating temperature range of -40C up to +80C.

Due to ease and speed of assembly to the small volume intricate/flexible connections of high-value devices, 9175 connectors can be used for connecting two or three wires between PCBs in high-volume consumer market applications, for example speakers, buzzers, microphones, and vibration mechanisms.

Molex’ Mini-Fit RTC vertical headers can withstand high SMT solder-reflow temperatures and are compatible with lead-free RoHS reflow processes

Molex has released the 4.20mm pitch Mini-Fit RTC (RoHS Temperature Capable) vertical headers, providing a cost-effective solution for mid-range power applications that require high density and current carrying capability. Designed with a high-temperature LCP housing that can withstand high SMT solder-reflow temperatures, the headers guarantee compatibility with lead-free RoHS reflow processes.

In addition, the press-fit PCB pegs provide polarisation during placement on the board and increased retention during the soldering process.

The Mini-Fit RTC headers share the same features of the Mini-Fit Jr headers, ensuring even greater compatibility and reliability.

The Mini-Fit key design allows it to mate with standard Mini-Fit receptacles.

Design flexibility is ensured through the choice of four to 12 and 24 circuit configurations.

The improved Mini-Fit Plus HCS male pins provide up to 12A per circuit when mated with the 16AWG Mini-Fit Plus HCS female crimp terminal.

The elliptical contact dimple design increases durability, doubling to tripling the number of mating cycles that standard Mini-Fit terminals will survive.

Terminals are available in post-plated versions only, enhancing the electrical performance and minimising the contact resistance of the mating interface.

The gold-plated terminals are suitable for ‘hot-pluggable’ applications.

The AdvancedMC Plug is manufactured using a tightly specified process and offers the highest degree of contact reliability and protection against wear and corrosion

The Harting AdvancedMC Plug has been developed to further enhance the contact reliability of the connection of AdvancedMC modules and MicroTCA backplanes. The new connector replaces the card edge and associated gold contact pads of the AdvancedMC module, which can suffer from variable surface quality and unstable tolerances and are expensive to produce.

The AdvancedMC Plug, on the other hand, is manufactured using a tightly specified process and offers the highest degree of contact reliability and protection against wear and corrosion.

The design of the new connector means that the insertion force of the module is reduced significantly, while the PCB thickness is no longer limited to the specified value of 1.6mm +/-10%.

Depending on the PCB design, the signal integrity behaviour is superior to that obtained with the card edge gold pads.

The AdvancedMC Plug is mounted on the module via the pin-in-hole reflow soldering technique, and is pick-and-place compatible.

It is designed according to the AMC.0 specification and can be used in both MicroTCA and AdvancedTCA applications.

It can be used for MicroTCA carrier hub (MCH) applications, in conjunction with the MCH plug.
