  • Publication number: 20230137877
    Abstract: No-remelt solder joints can eliminate die or substrate movement in downstream reflow processes. In one example, one or more solder joints between two substrates can be formed as full IMC (intermetallic compound) solder joints. In one example, a full IMC solder joint includes a continuous layer (e.g., from the top pad to bottom pad) of intermetallic compounds. In one example, a full IMC joint can be formed by dispensing a no-remelt solder paste on some of the pads of one or both substrates to be bonded together.
