What is solder paste?
Soldering paste is a critical component in the process of surface mount device assembly. It fills tiny gaps between components and provides a conductive medium for heat to flow from the soldering iron,through the solder joint, and into the metal on either side of it. This first blog post will explore what solder paste is and how to use it properly during SMD assembly
A solder paste is a mixture of metal alloys, fluxes, and solvents that are created into a thick sticky paste.
This thin layer serves as the medium for attaching components to printed circuit boards (PCBs).Solder pastes come in different thicknesses from very thin down to approximately 50 microns. The thicker formulations can be used with stencil printing whereas thinner ones require screen-printing techniques. Thicker types will stay on the PCB surface better than thinner ones but it also depends on other factors such as print technique and
