Pájení
Pájení is a process used to join two or more metal items together by melting and putting a filler metal (solder) into the joint, the filler metal having a relatively low melting point. The filler metal is not melted over the joint itself, but rather is melted by the heat of the joint and then flows into the close-fitting gap between the joined parts by capillary action. Once the heat source is removed, the filler metal cools and solidifies, creating a strong electrical and mechanical bond.
The process requires careful control of temperature to ensure the solder melts and flows properly without
