    CATCHING COUNTERFEITS
    Verifying Component Authenticity Using Decapsulation
    Decapsulation is a process that has been around for some time and has many different applications. Whether for analysis or verification purposes, the goal is the same: expose the die to perform the task at hand. While different methods are available to achieve this, manual etching has become a primary choice for exposing the die, as it leaves the device in question functional.

    FIXING THE FENCE
    RF Shield Rework
    RF shield rework is difficult due to continually shrinking package sizes, reduction of pitch and reduced clear space available around components. This increased density and complexity drives new techniques for removing and replacing RF shields. A new solution involves high-energy conduction heating and custom tips.
