Tip Perakitan Penting:
- Orientasi Komponen: Pay close attention to the orientation of polarized components such as LEDs, diodes, and integrated circuits (ICs). Incorrect orientation can prevent the device from functioning or cause damage.
- Soldering Technique: Ensure proper soldering technique, creating shiny, cone-shaped joints. Avoid cold solder joints (dull, lumpy) or solder bridges (solder connecting adjacent pads).
- OLED Display Alignment: When soldering the OLED display, ensure it is properly aligned with the mounting holes on the PCB before fully soldering its connections. This will prevent stress on the display module during final assembly.
- 3-Layer Structure: The kit is designed with a 3-layer structure (Effect Display Layer, Component Placement Layer, Protective Layer) for safety and aesthetics. Assemble these layers using the provided standoffs and screws after all soldering is complete.
