What is BGA Chip ? - RayPCB

Hidden Gold Inside BGA IC Chips! Inside many BGA (Ball Grid Array) IC chips, you can find tiny gold wires used to make electrical connections between the silicon die and the chip’s internal pins. These gold wires are extremely fine — often thinner than a human hair — but they are made of real gold because gold conducts electricity perfectly and never rusts or oxidizes. When you open a BGA chip, you’ll see a small silicon die at the center, usually surrounded by epoxy or black resin. Beneath that

CPU reballing is a technique used to repair or replace the solder balls that connect a CPU (Central Processing Unit) to a motherboard, particularly in devices like laptops and smartphones where the CPU is directly soldered to the board (BGA, or Ball Grid Array). This process involves removing the old solder balls, cleaning the contact points, and then applying new solder balls, often using specialized tools and techniques. It's a repair method for issues like overheating, crashing, or other faul
