Low Resistance LGA Connector Offer Lead-Free Option
In an effort to improve assembly efficiency and reduce the amount of lead content in finished products, many electronics manufacturers have selected a land grid array (LGA) as part of their integrated circuit package.
Fujipoly’s WBC Matrix Connector is the ideal interconnect pad for LGAs with 200 or more circuit board I/Os. After inserting the WBC pad between the circuit board and components, all that is necessary to make reliable electrical contact is even pressure. This eliminates the need to solder or rework components on the board.
The highly reliable connector is embedded with 300 to 2,000 curved wires per cm2 and provides a current carrying capacity of 500 mA/mm2. The curved orientation of the metal conductors allows for repeated compressions without a loss in performance. This is ideal for applications that require multiple inspection processes.The low resistance silicone-based WBC connector is available from stock in sizes up to 50 x 50 mm and thicknesses of 0.5 or 1.0 mm.
