Disassembling tool and method for disassembling a circuit board from a housing, and assembly of a circuit board, a housing and the disassembling tool

A method for disassembling a circuit board from a housing, said method being implemented using a disassembling tool, the disassembling tool including a rod section and first and second protrusions projecting radially from the rod section and spaced apart from each other with one on top of the other, the circuit board being mounted in the housing and having a board edge blocked by a stop protrusion of the housing, the circuit board being provided with an indentation adjacent to the stop protrusion, said method comprising:

• (A) extending the rod section through the indentation;
• (B) rotating the rod section axially such that the second protrusion is displaced to a position below the circuit board and the first protrusion pushes the stop protrusion away from the board edge of the circuit board;
• and
• (C) displacing the rod section upwardly relative to the housing such that the circuit board is lifted upwardly and outwardly of the housing by virtue of upward movement of the second protrusion.

An assembly of a circuit board, a housing and a disassembling tool, comprising:

• a housing having a peripheral wall with an inner wall surface, and a stop protrusion projecting from said inner wall surface;
• a circuit board mounted in said housing and having a board edge that is blocked by said stop protrusion, said circuit board having an indentation disposed adjacent to said stop protrusion;
• and
• a disassembling tool having
• a rod section,
• a first protrusion projecting radially from said rod section, and
• a second protrusion projecting radially from said rod section and spaced apart from and disposed below said first protrusion, said second protrusion and said first protrusion defining a non-zero degree angle therebetween with respect to an axis of said rod section;
• wherein said rod section is extended through said indentation in said circuit board and is rotated axially such that said second protrusion supports a bottom face of said circuit board and said first protrusion pushes said stop protrusion away from said circuit board, said rod section being displaceable upwardly relative to said housing to permit upward movement of said circuit board together with said disassembling tool.
