Samsung BN59-01391A Smart TV Remote Control teardown knolling
Plastic Shell (Front)
Material: Plastic
Manufacturing: Injection molded using a custom mold for shape and precision.
（Remove the screws with a small Phillips screwdriver. ）
Mounting Screws ×2
Material: Metal
Manufacturing: Metal wire is cold-forged to form the screw head, and threads are formed using a thread rolling machine for high speed and accuracy.
Surface is treated with black oxide coating or black nickel plating to create a rust-resistant and visually appealing black finish.

Plastic Shell (Back)
Material: Plastic
Manufacturing: Injection molded using a custom mold for shape and precision.
Plastic Button
Material: Plastic
Manufacturing: Molded via injection molding for shape and function.
Silicone Buttons
Material: Silicone
Manufacturing: Molded using compression molding, then printed color on the surface.
Solar Panel
Materials: Silicon, glass (low-iron tempered glass with Anti-Reflective Coating coating), plastic, metals, wires with rubber tubing
Manufacturing: Layers of silicon cells are sandwiched between tempered glass and protective plastic sheets. Electrical wires and rubber tubing are added for connectivity and sealing.
Printed Circuit Board
Materials: Core of non-conductive material: Fiberglass-epoxy composite (FR4), copper traces, solder mask
Manufacturing: The fabrication involves imaging and etching copper layers, drilling holes, plating with copper, and laminating layers to form the base circuit. The board is etched with copper circuits, and components are soldered on via wave soldering or reflow techniques.

two design elements that interest me：
One interesting design element is the silicone button, which appears to be made from two differently colored silicone parts: a translucent base and an opaque white key cap. I imagine the white silicone is placed into the mold first, followed by the injection of transparent silicone to encapsulate it. I’m not sure why the designer chose this approach, it may be for cost-efficiency—by limiting the amount of white silicone pigment used—while still maintaining the desired appearance on the surface.
Another interesting design is how the two VPC batteries are connected to the PCB. They are directly soldered onto the board with four solder joints, which makes the setup straightforward and easy to identify. However, this also leads to a potential weakness—these connection points are more prone to damage or disconnection, especially with frequent handling or over long-term use. It reminds me of my Apple Magic Keyboard can’t charge, so I couldn’t use the Bluetooth connection. I suspect that one of its solder joints may have come loose. I think the designer may have chosen this method for its speed and simplicity in assembly. It also makes repair or inspection relatively easy, as the joints are clearly exposed and accessible.
