Introducing Molex’s Quad-Row connector: The future of space optimized connectivity

Introducing the world’s smallest board-to-board connector – Molex’s revolutionary Quad-Row! With its compact size and unparalleled performance, the Quad-Row Board-to-Board Connector is changing the game when it comes to space optimized connectivity.

In today’s rapidly evolving world of consumer electronics, the demand for smarter, faster and more powerful technology has never been greater. At the electronic component level, this pace of transformation has created its own set of challenges in the architecture, electronic design, physical size and the overall performance of components. The shift towards reduced package size, higher signal density and electrical performance while meeting assembly processing requirements is inevitable.

From Idea to Reality: The Process Behind the Innovation

Molex_Smartwatch_ImageDevice manufacturers are working to pack various functions into the smallest possible device size to meet the demand for new features for consumers. As a result, design engineers are prioritizing miniaturization and performance as crucial factors to fulfill new design requirements.

To meet this growing demand, Molex has introduced Quad-Row, the world’s smallest board-to-board connector. This innovative solution offers 30% space-saving over conventional designs. This connector presents significant opportunities for achieving leading-edge, compactness and miniaturization while remaining compatible with standard surface-mount technology (SMT) processes.

This innovative design features pins arranged across four rows at a pitch of 0.175mm, resulting in an unprecedented 30% reduction in space requirements compared to traditional designs. This space-saving design allowed for high-density circuit connectivity and freed up considerable real estate for additional sensors and hardware needed to provide additional functionality.

What is Size without Strength?

Molex’s Quad-Row Board-to-Board connectors provide robust mating and reliable contact due to their sturdy design. The connector is equipped with internal armor and insert-molded power nails that shield the pins from damage during high-volume manufacturing and assembly. The connectors also have a broad alignment system, which enables easy and secure mating while reducing the likelihood of fallout.

With the ability to accommodate voltages up to 50V and a maximum current of 0.3A for signal and 3.0A for power nail, this connector possesses impressive electrical capabilities, including 35 milliohms contact resistance for signal and 20 milliohms for nail contact. Despite its small size, this compact connector measures only 2.00mm and a mated height of only 6.0mm, featuring a 250V dielectric withstanding voltage and 100 megohms insulation resistance.

Molex Quad-Row Board-to-Board Connectors are available worldwide in 32- and 36-pin configurations with 20- and 64-pin configurations coming soon. Plans are underway to support up to 100-pin counts. With a durability of 30 cycles, Quad-Row connectors operate at temperatures from -40 to +85 and come in embossed tape and reel packaging for automated assembly. The connectors are RoHS compliant and available with low halogen status.

Limitless Opportunities

Ideally suited for a variety of applications requiring increasingly smaller PCBs and flex assemblies, Quad-Row Board-to-Board Connectors meet product miniaturization demands, creating limitless opportunities across a wide array of industries and applications. As manufacturers continue to expand the functionality of small products like smartphones, smart glasses, earbuds, and AR/VR devices, their increasingly densely packed PCBs must remain height-scalable and maintain a small footprint. New connector designs like the Quad-Row can help them innovate without the concerns of signal integrity and PCB space limitation issues.
