Aries Electronics has introduced BGA Switch-A-Pitch adapters that allow for small pitch devices to be used with large pitch boards.

The new adapters in the series adapt 0.40mm devices to boards with a 1.00mm pitch.

The BGA Switch-A-Pitch adapters, part of the company’s line of Correct-A-Chip adapters, reduce costs by enabling the use of newer, tighter pitch devices with larger pitch boards, which are readily available and more economical, lowering the cost of the printed circuit board (PCB).

The adapters have tops with BGA landing pads on a 0.40mm pitch and bottoms fitted with BGA balls on a 1.00mm pitch.

Open space around the adapter tops provides space for further components to be added to the design at a lower cost.

High-density-interconnect (HDI) construction is reduced and the need for laser-drilled microvias on the motherboard is eliminated by adapting tighter pitch devices to larger footprints.

The BGA Switch-A-Pitch adapters enable the use of standard line and trace spacing down to 0.003in (0.076mm).

The adapters can operate at up to +221F (+105C) for FR4 and up to +266F (+130C) for lead free.

The recommended PCB size for a 1.00mm pitch is 0.020in (0.50mm).

Boards are 0.062in-thick FR4 or Rogers 370 HR with 1/2oz copper traces on both sides.

Solder spheres are 63/37 tin/lead or lead-free SAC 305.

The adapters feature non-solder mask-defined (NSMD) pads finished with electroless nickel immersion gold (ENIG).

As part of Aries’ Correct-A-Chip adapter series, the Switch-A-Pitch adapters are designed to save users both time and money.

Correct-A-Chip adapters allow the use of different termination styles or pitches on one board designed for an alternative style or pitch and can be fitted with either active or passive components for added functionality.

Aries adapters are available as adapter only or as a turnkey solution with mounted devices.

Specialising in custom design and production, Aries offers standard products as well as special materials, platings, sizes and configurations upon request.

The Switch-A-Pitch adapters are made to customer requirements.

The pricing for a typical adapter with 32 positions is USD6.50 (GBP4.15) each in quantities of 1,000.

Delivery is four to five weeks after the receipt of order.
