SIP encapsulation
SiP packaging achieves higher integration and smaller product size by highly integrating multiple chips and functional devices into a single package. MCOTI provides conductive adhesive, underfill and precision soldering process solutions, which can effectively enhance the mechanical connection strength between the chip and the substrate, reduce the impact of thermal stress on the solder joints, and improve the package's resistance to drops, thermal cycles and long-term reliability.

Improve component reliability with our innovative adhesive materials for solder joint reinforcement. We provide tailor-made solutions that support a variety of connection stabilization and optimization methods to help you ensure that semiconductor chips and other electronic devices maintain excellent performance throughout their life cycle. There are various methods for mechanical reinforcement of BGAs and other components, whether underfill, corner filling or corner fixing, each method has its own advantages and varies in terms of degree of reinforcement, amount of material, process speed, reworkability and CO2 emissions.

Underfill: It is the most reliable solution. Glue is dispensed on the side of the chip and the gaps between the solder balls are fully filled through capillary action;

Cornerfill: Dispensing glue at the four corners and partially filling the gaps between the solder balls can enhance the mechanical strength of the four corners of the chip/PCB;

Edgebond: only covers the four corners, and the dispensing height is greater than 50% of the chip body. It is suitable for large-sized chips, saving costs & can be repaired.
