pintakytkentätekniikan

Pintakytkentätekniikka, often translated as surface-mount technology (SMT), is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). This contrasts with through-hole technology (THT), where component leads are inserted into holes drilled in the PCB and soldered to pads on the opposite side. SMT components, also known as surface-mount devices (SMDs), are typically smaller and have no leads, instead possessing small terminations or balls that are soldered directly to the PCB surface.

The adoption of pintakytkentätekniikka has revolutionized electronics manufacturing. It allows for smaller, lighter, and more densely packed electronic devices, contributing to the miniaturization trend seen in consumer electronics. SMT also enables components to be placed on both sides of the PCB, further increasing component density and functionality. Automated placement machines are used for high-speed, precise placement of SMDs, leading to increased manufacturing efficiency and reduced labor costs compared to manual THT assembly. This technology is fundamental to the production of virtually all modern electronic devices, from smartphones and computers to automotive electronics and industrial control systems.
