ELECTRONICS: Ironwood Electronics‘ released a new board-to-board socket adapter for 352 pin BGA, 1mm pitch, 27×27mm IC size. Board-to-board high performance socket adapter consists of two modules (female socket module and male pin module). Patent pending female socket module was built with machined pins epoxy over molded into an assembly that matches the male pin module with similar construction. SF-BGA352B-B-42 (female socket module) can be soldered to a mother board using standard soldering methods without warping that result in reliable connection to PCB. Similarly, SF-BGA352B-B-41 (male pin module) can be soldered to an upgraded daughter board. Both modules are constructed with high temperature FR-4 substrate assuring match with target PCB’s and preventing failures that occur with CTE mismatch. SF-BGA352B-B-41 is plugged into SF-BGA352B-B-42 on the board, thereby daughter and mother boards are interconnected and the system is ready to go. The modules come with both lead and lead free solder ball type options. The board-to-board socket adapter pair requires half the force of conventional connectors at 10 pounds for the 352 pin interface for ease of operation. The electrical path of the board-to-board socket adapter is a high priority performance issue with the physical length from the top connection point on the male pin module to the solder ball on the female socket is 4.5 mm. This is the shortest connection length by far for machined pin sockets, therefore providing better transmission of high frequency signals. These board-to-board socket adapters passed environmental tests (MIL-STD) and qualified for various range of applications including automotive, military, communications, industrial, etc. The board-to-board socket adapter line is available in many different pin counts with 1mm & 0.8mm pitch, and customs can be delivered in days.
Pricing for the SF-BGA352B-B-42 @qty1 = $110.00 each and SF-BGA352B-B-41 @qty1 = $89.00
Just when you thought mobile technology couldn’t get any more personal, Proctor & Gamble have come up with a way to put your mobile where your mouth is, in the form of a Bluetooth 4.0 connected toothbrush.
MCU manufacturers have become excellent sources for information you can use to get a head start on your next design. In addition to the normal data sheets and evaluation boards, MCU manufacturers also often provide complete reference designs -- working designs that establish a proven baseline for creating your own custom design.
