0.4-mm pitch board-to-board connector targets portable electronics design

MYRTLE BEACH, SC?Billed as the industry’s smallest 0.4-mm pitch board-to-board connector, AVX Corp.’s (www.avxcorp.com) 5802 Series low-profile connectors feature a slim form factor of 0.8-mm stacking height and 3.2-mm width, including tails.

The connectors are designed for internal wiring of mobile devices, such as cell phones, MP3 players, digital still and video cameras, PDAs, and game players. They are also suitable for connecting LCDs in camera modules, CMOS/CCD image pickup devices, and other space-sensitive board applications.

Mark Jarman, a product manager at AVX, says the connectors “are ideal for portable devices due to a design that combines ultra-small size with high-reliability. The space-saving design allows engineers to be flexible without sacrificing performance or ruggedness.”

The area beneath this 10- to 60-position connector family is fully insulated, allowing designers to run tracks beneath the device. To ensure low insertion force while maintaining high retention and separation force, the connector contact employs a twin rib structure, which is also designed to ensure that contacts are wiped clean from contaminants (such as dust and flux) during every mating cycle.

Providing an audible and tactile “click” mating, the plugs are shaped by insert moldings and enclosed metal fittings on the receptacles to improve breaking strength against any drop impact. A nickel barrier and solder-on receptacle contacts prevent solder wicking, while pinched-type dual contacts are designed to further enhance contact reliability.

The 5802 Series has a 0.3-amp rated contact current, 50-volt rated contact voltage, gold-plated beryllium copper contacts, UL94V-0 heat-resistant insulator material, and -40° to 85° C operating temperature.

Pricing typically starts at $0.03 per position in low volumes, with a lead time of 8 to 12 weeks.
