Latest Patents
One of Yinggang Tu's latest patents is titled "Ball grid array resistor network having a ground plane." This invention features a ball grid array resistor network designed to reduce noise and enhance signal integrity. The network includes a substrate with a first and second surface, along with vias extending through the substrate. Resistors are strategically placed on the first surface, while conductors are positioned over the vias and connected to the resistors. A cover coat protects the conductors and resistors, and a ground plane is situated on the second surface, topped with an insulating layer. Ball pads are located over the vias and are electrically connected, with solder spheres attached to facilitate connections.
Another significant patent is the "Ball grid array resistor network." This invention utilizes a planar substrate made from organic material, preferably a printed circuit board. The substrate has both top and bottom surfaces, with a ball pad located on the bottom surface. A low-temperature resistor is connected to the ball pad, and a solder mask covers the first surface, leaving the ball pads exposed. A conductive ball is attached to the ball pad, with reflowed solder paste ensuring a secure connection.
