Trükkplaadi

Trükkplaadi, also known as a printed circuit board (PCB), is a substrate used to mechanically support and electrically connect electronic components using conductive tracks, pads, and other features etched from copper sheets laminated onto a non-conductive substrate. Trükkplaadi are the backbone of virtually all electronic devices, from simple calculators to complex supercomputers.

The manufacturing process of a trükkplaadi typically involves several stages. First, a design is created using specialized software. This design dictates the layout of the conductive paths and component placement. The design is then transferred to a copper-clad laminate board. Unwanted copper is etched away, leaving only the desired conductive tracks. Holes are drilled for component leads and vias, which are conductive connections between different layers of the board. Finally, components are soldered onto the board, either manually or through automated processes.

Trükkplaadi can be single-sided, double-sided, or multi-layered, depending on the complexity of the circuit. Multi-layered boards allow for denser component placement and more intricate interconnections. The materials used for trükkplaadi vary, with fiberglass reinforced epoxy resin (FR-4) being the most common substrate. Other materials are used for specific applications requiring higher temperature resistance or flexibility. The prevalence of trükkplaadi has revolutionized electronics manufacturing, enabling miniaturization, increased reliability, and cost-effective production of sophisticated devices.
