Elastomer socket overview

  • Previous technology

    MBP Elastomer Socket

    Elastomer made from existing particles

    • Nonlinear spherical conductive particles are formed in a column shape to create a connecting pin.
    • The contact between conductive particles is take place in dots, making tehm vulnerable.
    • The nature of the conductive particles makes it difficult to extend the length (thickness) of the connecting pin.

    MBP Elastomer Socket

    Micro Brick Particles and Elastomer with a New Structure

    • Brick-shaped conductive particles are used to make a connection pin solid like a block.
    • A new particle can extend the length of a connecting pin by reducing the number of conductive particles inside the conductive particle column.
    • It can be made to be resistant to impact while lowering the contact resistance by increasing the contact area between conductive particles.
    • The length of the connecting pin can be extended while the contact pressure against the semiconductor IC can be lowered.

New Paradigm Creation of 'MBP' Technology

  • Existing Elastomer Paradigm

    • As the pitch decreases, the thickness also decreases.
    • As the pitch decreases, the resistance increases.
    • As the thickness increases, the resistance increases.
    • There is a height limit to increase the thickness.
    • As thickness decreases, lifespan decreases.

  • Key Quality Factor 'Particles'

    • Reducing 'particle' size
    • Reduced 'particle' heat quantity
    • Increase the number of 'particles' in the 'particle' column
    • Limit on the number of 'particles' present in a 'particle' column
    • Increase the amount of shrinkage, increase the pressure deviation within the area

  • 'New Paradigm'
    MBP elastomer socket

    • MBP elastomer socket with Micro Brick Particles technology
    • Thickness can be increased even when the pitch is reduced
    • Low resistance even with reduced pitch
    • Low resistance can be maintained even with increased thickness
    • Thickness and height can be increased with an appropriate number of particles
    • Lifespan is improved by maintaining the proper amount of shrinkage
