ABSTRACT:
An electronic assembly for use in a downhole tool includes a damming boot deployed about at least one integrated circuit component on a circuit board. The boot is disposed to house the integrated circuit leads and solder joints in a substantially sealed cavity between the circuit board, the integrated circuit body, and an inner surface of the damming boot. The boot is also disposed to support the integrated circuit body and thereby improve the shock and vibration resistance of various electronic assemblies used in downhole tools. The invention also tends to improve the reworkability of downhole electronic assemblies.
