It involves inserting component leads or pins into specially designed plated through-holes on the PCB, creating a press-fit connection. This process is often used for connectors or components that require frequent replacement or rework.

6. Flip-Chip Bonding: Flip-chip bonding is a technique used to connect bare semiconductor chips directly to a substrate or PCB. In this process, the chip is flipped, and its bumps or solder balls are aligned with corresponding pads on the substrate. Pressure or heat is applied to create electrical and mechanical connections. Flip chip bonding allows for high-density packaging and improved electrical performance.
