New switch-a-pitch adapters from Aries provide even smaller pitch landing pads for use on larger pitch boards

Article Type: New products From: Circuit World, Volume 35, Issue 4

Aries Electronics, an international manufacturer of standard, programmed and custom interconnection products, has expanded its line of BGA switch-a-pitch adapters that simplify high density interconnect construction to enable the use of smaller pitch devices on larger pitch boards.

The series now includes models with tops where the BGA landing pads are on a 0.40 mm pitch and adapter bottoms are populated with BGA balls on a 1.27 mm pitch.

The new adapters significantly reduce costs. Designers can use readily-available, and therefore less expensive, larger pitch boards because the adapters allow new, tighter pitch devices to be placed on existing larger pitch designs. In addition, manufacturers can add components to designs at much lower costs, since the adapter tops leave open space around the location for the replacement device.

The switch-a-pitch design eliminates the need for laser-drilled microvias on motherboards. Standard line and trace spacing down to 0.003 in. (0.75 mm) can be used.

The adapters are 0.062 in. (1.57 mm) thick FR4 or Rogers 370 HR with 1/2 oz copper traces on both sides. The non-solder mask defined pads are finished with electroless nickel immersion gold and have solder spheres of 63/37 lead/tin or of lead-free SAC305 alloy. The devices can operate up to 221°F (105°C) for FR4 or up to 266°F (130°C) for lead-free. Suggested PCB pad size is 0.022 (0.55 mm) for a 1.27 mm pitch.

Switch-a-pitch adapters are part of Aries' exclusive Correct-a-Chip adapter series that saves end-users time and money by reducing board design time. Correct-A-Chip adapters can incorporate both passive and active components and can enable the use of one termination style or pitch on a board designed for a different style or pitch.

The adapters are available in various forms, including panelised, adapter only or as a turnkey solution with mounted devices. Specializing in custom design and production, Aries offers standard products as well as special materials, platings, sizes and configurations upon request.

Switch-a-pitch adapters are custom made to customer requirements. A typical adapter with 64 positions is priced at $25 each for a quantity of 300 adapters.
