Before you start assembling the PCB, please carry out a PCB test and check if all keys function. Before assembling the screws, remove the yellow tape on the stand-offs of PCBs. Whether or not to use foam sets is optional. Cut the space bar area of the foam set to fit your keyboard layout. To assemble the PCB and the plate, you must use all 14 screws. After removing the C-type port once, you cannot put it on again. Remove the daughter board installed above the arrow keys before usage, since electricity may go through. Daughter board and C-type ports are made of FR-4, which means you must use a nipper. If you use tools made for other uses such as scissors, the product may be damaged. These PCBs, such as photos, are not eligible for exchange or refund. The stabilizer mounts normally.
