pintaasennuksia

Pintaasennus, also known as surface mount technology (SMT), is a method for producing electronic circuits where the components are mounted directly onto the surface of a printed circuit board (PCB). This contrasts with through-hole technology, where component leads are inserted through holes in the PCB and soldered on the opposite side. Pintaasennus components are typically smaller and have leads that lie flat against the board, allowing for much higher component density and smaller overall circuit sizes.

The process of pintaasennus involves several steps. First, a solder paste is applied to the designated pads on the PCB using a stencil. Then, automated pick-and-place machines accurately position the surface-mount components onto the solder paste. The assembled board then goes through a reflow soldering process, where it is heated in an oven to melt the solder paste, forming electrical and mechanical connections between the component leads and the PCB pads. After cooling, any remaining flux residue is typically cleaned off.

Pintaasennus offers several advantages, including reduced manufacturing costs due to automation and smaller component sizes, improved circuit performance with shorter signal paths, and the ability to place components on both sides of the PCB. It has become the dominant technology in modern electronics manufacturing, enabling the creation of smaller, more powerful, and more complex devices.
