käsinsijoitus

Käsinsijoitus, often translated as "manual placement" or "hand placement," refers to the deliberate and careful positioning of components onto a printed circuit board (PCB) by human operators. This process is typically employed in situations where automated pick-and-place machines are not suitable or economical. These situations can include the assembly of prototypes, small production runs, or when dealing with very large or unusually shaped components that automated machinery might struggle to handle.

The operator uses specialized tools, such as tweezers, vacuum pick-up tools, and fine-tipped soldering irons, to pick up individual electronic components from their packaging and place them onto the designated pads on the PCB. Precision is paramount, as incorrect placement can lead to circuit malfunctions, shorts, or the inability of the board to function at all. Operators must have a good understanding of component polarity, orientation, and the layout of the PCB.

While Käsinsijoitus is labor-intensive and generally slower than automated assembly, it offers flexibility and a lower barrier to entry for custom or low-volume electronics manufacturing. It requires skilled personnel with good dexterity and attention to detail to ensure the quality and functionality of the assembled PCB. In some cases, it is used in conjunction with automated processes to place specific components that cannot be handled by machines.
