SMD use is, however, challenging. No well-defined established accepted pedagogy complete with a set of competently designed commercially-supported properly-documented SMD electronics methods and systems has been available to aspiring builders. SMD components entail unique technical characteristics including different construction and assembly technique requirements, parts management challenges for near-microscopic components, unfamiliarity with new parts types by personal builders, and difficulty in parts identification for tiny parts too small to bear a helpful readable marking visible to the naked eye.
With careful selection and proper circuit design. SMD parts can provide for additional new features in electronics devices, but configuring and managing many newer SMD parts often requires special skills, and still more specialized SMD parts, such as microcontroller (MCU) or microprocessor (MPU) control using specially designed printed circuit boards (PCBs) with appropriate traces allocated to provide control signaling and data via SPI or I2C control. The datasheet for such a modern MCU easily can exceed one thousand pages, and understanding such a device well enough to control a single adjacent SMD device in a circuit becomes a daunting prospect for a hobbyist or student.
