According to AVX Corp., its 5802 series 0.4-mm pitch board-to-board connectors are the smallest in the industry. Their form factor also includes a 0.8-mm stacking height and 3.2-mm width, including tails, with 10 to 60 positions. The area beneath the connectors is fully insulated, allowing designers to run tracks beneath the device for a more flexible board layout.

The 5802 series of board-to-board connectors from AVX Corp. have a 0.4-mm pitch, 0.8-mm stacking height, and 3.2-mm width, making them the smallest in the industry, according to the company.

To ensure low insertion force while maintaining high retention and separation force, the connector contact employs a twin rib structure, which also ensures that contacts are wiped clean from contaminants like 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 further enhance contact reliability. Other specifications include 0.3-A rated contact current, 50-V rated contact voltage, gold-plated beryllium copper contacts, UL94V-0 heat-resistant insulator material, and a –40°C to 85°C operating temperature. 

The AVX 5802 connectors suit use as low-profile and space-efficient board-to-board connectors that are required for the internal wiring of mobile devices. They also can be used to connect LCDs in camera modules, CMOS/CCD image pickup devices, and other space-sensitive board applications. Pricing typically starts at $0.03 per position in low volumes with a lead time of eight to 12 weeks.
