-The BTC 5100 is a compact keyboard produced by BTC that uses BTC tactile foam and foil switches. It is **not** to be confused with the BTC 5100**C** that utilizes an assembly with a conductive dome with slider system over a PCB.+**BTC 5100** is used to describe two similar-looking compact keyboards produced by BTC: the //BTC 5100// using their capacitive tactile foam and foil switches, and the //BTC 5100//**//C//** that utilizes thier conductive dome with slider system over a PCB.

 This keyboard crams all of the keys from a full-size keyboard into a 80 key compact keyboard through several design decisions. The alphanumeric block utilizes a 60%-style layout that truncates the right Alt and Ctrl keys along with splitting the right Shift key to make space for an L-shaped arrow key cluster in the bottom-right corner. Furthermore, the keyboard shortens the right side of the keyboard, visible with the Backspace, "pipe/backslash", and Enter keys; causing the keyboard to be 14.5 units wide. This main alphanumeric block utilizes BTC tactile foam and foil switches, with a Cherry MX compatible keycap mount. This keyboard crams all of the keys from a full-size keyboard into a 80 key compact keyboard through several design decisions.

-The keyboard features a top case with an integrated plate. The top case screws into the bottom case via six screws. The bottom case has four anti-slip rubber pads on the case, along with two flip-out feet to adjust the typing angle. The flip out feet do not have rubber padding. The bottom case features two stickers - one listing the serial number and variant, and the other listing the FCC ID.+<WRAP wfix right>

 When opening the keyboard, the capacitive PCB can be found screwed into the top case. It consists of the capacitive matrix, LEDs for the lock lights, and jumper wires for the matrix. The PCB is then soldered into a daughterboard that connects with the PCB via pin headers. This daughterboard contains the internal controllers, PCB components, a socket for the cable, and grounding wire which is screwed onto a metal foil that covers most of the backing of the PCB. Both the main PCB and the daughterboard have printing indicating a manufacture date - the first two digits for the year, and the last two is presumed to be for the week. When opening the keyboard, the capacitive PCB can be found screwed into the top case.

 The sliders fit loosely into the top case with its integrated plate and housings, with no clips used to keep the sliders affixed within the housing. The foam and foil pads are affixed onto the slider, with clips in the slider hooking into a plastic backing on the foam pad. The "foil" component is glued into the foam, and consists of a capacitive plastic coated with a foil metal film. The sliders fit loosely into the top case with its integrated plate and housings, with no clips used to keep the sliders affixed within the housing.

 On the external side of the top case, linear springs loosely fit over the sliders for the top row of keys, whilst buckling rubber sleeves are placed over the alphanumeric block. There is a main mat of rubber sleeves that go over the main alphanumeric block excluding the entire right side. Individual buckling rubber sleeves are used for the modifiers, Tab, Caps Lock, "Fn", Backspace, Enter, and arrow keys. A special red buckling rubber sleeve is used for the spacebar, with the red sleeve being stiffer than the other sleeves. On the external side of the top case, linear springs loosely fit over the sliders for the top row of keys, whilst buckling rubber sleeves are placed over the alphanumeric block.
