Case for an electronic device, method of fabrication and storage device using the same

A method of fabricating an electronic device case, the method comprising:

• providing a conductive material;
• casting a top case having first fastening members and a bottom case having second fastening members using the conductive material;
• forming a coating layer on each of the top case and the bottom case including surfaces of the first and second fastening members;
• and
• removing the coating layer from surfaces of the first fastening members and the second fastening members in areas that contact each other.

A storage device comprising:

• a printed circuit board (PCB) having electronic components, including a controller and a non-volatile memory device, mounted on a front surface of the PCB and having fastening holes at respective corners of the PCB;
• a top case covering the front surface of the PCB and having first fastening members at positions corresponding to the fastening holes;
• and
• a bottom case receiving the PCB to cover a rear surface of the PCB, and having second fastening members at positions corresponding to the first fastening members,
• wherein each of the top case and the bottom case includes a coating layer except for areas of interface between the first fastening members and the second fastening members.
