HIROSE’S SMALL BM25 SERIES HYBRID BOARD-TO-FPC CONNECTOR HANDLES UP TO 9 AMPS

CHICAGO, ILLINOIS — December 2, 2015 — Hirose, a leader in the development of innovative connector solutions, has developed a small, board-to-flexible printed circuit (FPC) connector designed for battery pack connections in mobile devices. The hybrid BM25 Series connector is rated up to 9 Amps per pin for power contacts and 1 Amp per pin for signal contacts. With a space-saving design that offers a stacking height of only 0.7mm and a depth of 2.6mm, the low-profile BM25 Series delivers twice as much current-carrying capacity in a smaller profile than traditional technologies.

Offering contact resistance as low as 5m ohms or below for power contacts and 30m ohms or below for signal contacts, the BM25 Series provides significant power savings by utilizing a design that minimizes contact resistance.

A six point, highly reliable clip-like contact structure combined with a robust eight-point metal lock provides a mating force that is resistant to intense vibration and drop impact. The BM25 Series also utilizes a metal guide structure that prevents housing damage due to incorrect mating. With a breaking strength of 70 N, the metal guide design ensures that if the header and the receptacle should be mated incorrectly, the metal hold-downs would dissipate the force and prevent housing damage.

Offering simple and easy mating operation, the BM25 Series utilizes guide ribs that self-align up to 0.48mm in the pitch direction and 0.46mm in the width direction.

“Our ultra-compact BM25 Series hybrid board-to-FPC connector delivers more power in a smaller package than competing technologies on the market,” said Rick van Weezel, Vice-President of Sales and Marketing for Hirose Electric USA. “Designed for mobile device connectivity, the BM25 Series connector meets the power and signal transition needs for a wide variety of handheld consumer, medical, point of sale, inventory control, and other wireless equipment.”

The BM25 Series has an integrally molded header and receptacle that prevents solder wicking. This space saving connector is suitable for vacuum pick & place equipment.

The BM25 Series connector has a rated voltage of 30 V AC/DC, a power contact resistance of 5 m ohms maximum and a signal contact resistance of 30 m ohms maximum, an insulation resistance of 1000 M ohms minimum, and an operating temperature of -40 degrees C to +85 degrees C.

Space saving, 0.5mm pitch FX20 Series connector requires only 120 positions to carry 60 Amps versus 200 positions from competing connector technologies?

HIROSE INTRODUCES RUGGED SELF-ALIGNING, FLOATING BOARD-TO-BOARD CONNECTOR

CHICAGO, ILLINOIS — January 6, 2016 — Hirose, a leader in the development of innovative connector solutions, has designed a board-to-board connector with a highly reliable floating contact mechanism and self-alignment structure that simplifies assembly. Providing +/- 0.6mm floating in the X and Y axis directions, the FX20 Series absorbs mounting misalignment from multiple stacking connectors as well as PCB shrinkage caused by high temperatures.

Ideal for industrial and vehicle applications, the FX20 Series is a new member of Hirose’s FunctionMax family. It has a highly reliable double beam contact structure that provides high shock and vibration resistance. Each contact beam has a different vibration characteristic and a different contact force, which widens the frequency range and reduces resonance. In this unique design, the first beam has a 0.5N contact force, while the second beam has a 0.35N contact force. The FX20 Series is resistant to sulfur dioxide, and operates in environments up to 105 degrees C, with thermal shock protection from -40 degrees C to +85 degrees C for up to 1000 cycles.

The board-to-board connector’s double beam contact structure also provides self-cleaning functionality. The first beam eliminates dust from the contact path, securing an ultra-reliable contact path for second beam. The contacts of both the header and receptacle are also enclosed in the housing, which provides advanced protection against dust. This feature also reduces the risk of dust adhesion due to solder waste and flux during the mounting process. Both the FX20 Series and Hirose’s FX18 Series feature the same stack height variations as well as a floating design, allowing use of both series on the same board in a parallel configuration, providing high speed and high current capability.

The space saving FX20 Series connector has a compact 0.5mm pitch design that delivers a 0.5 Amp current per pin capacity. Using highly conductive contact materials that minimize loss and reduce heat generation, the FX20 Series connector requires only 120 positions to carry 60 Amps versus 200 positions from competing technologies.

“Hirose’s FX20 Series board-to-board connector was developed to provide engineers with unparalleled design flexibility. From the floating mechanism, self-aligning structure and dual beam contact construction to the flexible circuit patterning and level surface for pick-and-place attachment, the FX20 Series simplifies the design and assembly process to provide time and cost savings,” said Rick van Weezel, Vice-President of Sales and Marketing for Hirose Electric USA.

The FX20 Series offers large mating guide pins on the header, which allows for +/- 1.2mm self-alignment producing easy mating. The connector also features a flat, leveled surface that allows for automatic pick-and-place mounting. To save valuable space on the board, the area beneath the FX20 Series connector is available for other PCB circuits and through-hole assemblies.

The connector is offered in a parallel stacking version with stacking heights of 15, 20, 25 and 30mm, as well as a right-angle mating type. Both types are available from 20 to 140 positions, and range from 17.4mm to 47.4mm in width.

The FX20 Series is designed for a wide range of applications including automotive/vehicle, broadcast equipment, base station transceivers, auto navigation/ radio, industrial equipment, measuring instrumentation, medical devices, multifunction printer/copiers, projectors, smart meters and more.

Should cables with crimp connections be pull tested before leaving the Factory?

No one should ever have to experience wires coming loose and pulling out of their crimp terminals.

While pull testing is a mandatory step in the set up portion of the manufacturing process, it is a destructive test and is not intended for production testing.

To insure that wires stay put, several steps must take place before production begins.

Crimp contacts have a pull force range, a Crimp height range, and an Insulation Crimp height range specified by the manufacturer.  It is the responsibly of the assembler to verify that the specifications will be met by test and validation during the job set up.

To do this the assembler takes the wire, crimp terminal and tooling (hand or automated crimper) that are for the specific job at hand and crimps a test lot.  The test lot is then measured for crimp and insulation height and finally pull tested using a crimp pull tester with a telltale gauge.

Results are recorded and compared with the manufactures parameters.  If all measurements are within spec the cable is then released to production.

If the test identifies any condition where the spec is not achieved adjustments are made to tooling and tests are repeated until the spec is met.

This insures that all cables made with the specified wire, crimp terminals and tooling will not pull out in the field.

Can I save money by switching from Gold plated contacts in my cable connectors to Tin plated contacts?

Before you can make that decision you have to look at the trade offs between the virtues of the two materials. While Tin plated contacts can be up to 4 times cheaper than the same contact plated in gold there are issues to consider regarding mating cycles, conductivity and resistance to oxidation.

Gold is very durable. Gold contacts can be mated and unmated many more times before degrading to the base metal than the same connector using Tin plating.

Gold is also very resistant to corrosion; Tin on the other hand is very susceptible to corroding over time due to environmental conditions (high humidity, direct exposure to wet conditions especially salty wet conditions).

Tin is also subject to a process called Fretting. Fretting occurs in environments where mechanical vibrations cause small movements between the connectors surfaces or where expansion and contraction through temperature is present. The Fretting process can wear down the Tin contact surface over time and expose the base metal, which is even more prone to oxidation.

Tin can also be subject to galvanic corrosion. If a tin contact is mated to a dissimilar type of contact material (usually gold) as current flows across the surfaces metallic oxides can form at that union. These oxides have a relatively high resistance, which can degrade current flow.

Gold also has a lower contact resistance than Tin. Gold has a mated maximum contact resistance expectation of 20 milliohms whereas Tin is 50 milliohms.

So how do you chose if you should switch from Gold to Tin plating on cable contacts?

If you go down this checklist and you can check all of these boxes you should be ok with the switch from Gold to Tin if the Cable Connectors will:

psc-plate

*have a low number of lifetime mating cycles

*be used in a relatively Dry Environment.

*be free from continuous mechanical vibration

*be free from extreme temperature swings

* be mated to a similar (Tin) plated contacts

*operate above 50milliohm threshold

Should Cables be 100% tested before they leave the factory?

In any cable manufacturing endeavor consistency in all aspects of the process is key but it is not a means to an end in itself.  Along with 100% consistency in process you must have validation of the process by a comprehensive testing methodology.

That means every cable gets tested 100% before it can be signed off to ship.  For some cables that means testing at the final step of QC but for others it also includes in-process testing.  Some complex harnesses may have several electrical tests before they reach their final test.

As you’d imagine the testing methodology you choose is as important as the choice to test.  Not all testing is alike and not all methods guarantee a proper working cable.

You can test all cables 100% for continuity (shorts and opens) but that doesn’t insure a proper pin-out.  You can have continuity but at what resistance level?

At PSC we’ve chosen the industry gold standard Cirris Systems CR Easy Wire Tester.

https://www.cirris.com/products/testers/item/8-cr

The Cirris CR allows up to 32,000 test points, resistance threshold can be set from 0.1 Ohm to 500k Ohm.  The CR tests resistors, diodes and capacitors.  It will test in process and at final QC.

The Cirris CR “learns” from a “golden” cable and stores each cables characteristic by a unique filename.  Operators are alerted to cable pass/fail status by audible tone and Pass (Green) and Fail (Red) notifications on their PC’s when performing tests.

What I like best is its test reporting features.  For some of customers, we serialize each cable and provide test reports with each cable.  Soft copy test results are archived on all results and can be called up at anytime.

It’s a powerful way to test and it get’s you the cable you want each and every time!
