| Detailed Description: | BRISTOL, PA, March 2009 – Aries Electronics, an international manufacturer of standard, programmed and custom interconnection products, has added a unique Adapter Series to its extensive line of Correct-a-Chip Adapters that save end users both time and money.
The new BGA Switch-A-Pitch Adapters enable the use of smaller pitch devices with larger pitch boards.
The first Switch-A-Pitch Adapters in the series have tops where the BGA “landing pads” (on the top of the adapter) are on a 0.5mm, while the adapter bottoms are populated with BGA balls on a 1.27mm pitch.
These innovative adapters can reduce high-density interconnect (HDI) construction by adapting smaller pitch devices to larger footprints. In essence, the adapters allow the use of new, tighter pitch devices on existing larger pitch designs – which vastly lowers the PCB cost, since larger pitch boards are readily available and therefore more economical.
Since the top of the adapter board can leave open space around the small device, adapter manufacturers can add components to the design at a very low cost. The need for laser-drilled microvias on motherboards is eliminated. Standard line and trace spacing down to 0.003" (0.75mm) can be used.
Switch-A-Pitch boards are 0.062" (1.57mm) thick FR4 or Rogers 370 HR, with 1/2-oz. Cu traces on both sides. The non-solder mask defined (NSMD) pads are finished with electroless Ni immersion Au (ENIG) and have solder spheres of 63/37 Sn/Pb or of Pb-free SAC305 alloy. The device can operate up to 221°F (105°C) for FR4 or up to 226°F (130°C) for lead-free. Suggested PCB pad sizes include 0.022" (0.55mm) for a 1.27mm pitch.
Switch-A-Pitch Adapters are available in panelized form, as an 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. |
