juotostahna
Juotostahna, also known as solder paste, is a material used in the soldering of electronic components. It is a suspension of fine solder particles in a flux vehicle. The solder particles are typically made of a tin-lead alloy, although lead-free alloys are increasingly common. The flux vehicle is a chemical mixture that cleans the surfaces to be soldered, prevents oxidation, and promotes the flow of molten solder.
Juotostahna is applied to printed circuit boards (PCBs) using a stencil or a syringe. The stencil is
After application, the PCB with the juotostahna is heated in a reflow oven. The oven's controlled temperature
Juotostahna is a critical material in the manufacturing of modern electronics, particularly for surface-mount technology (SMT)
