Changes in the approach to ecology meant that the subject of environmental protection also burst into the area of electronics. The gradual withdrawal of subsequent harmful substances (mainly heavy metals) as part of the implementation of successive versions of the RoHS directive resulted in a very strong limitation of the scope of legal applicability of solders based on tin and lead (Sn60Pb40). They have been replaced with much more modern materials, in which tin occupies about 99% of the weight of the alloy, and the rest are admixtures of other metals (usually copper and silver). What is important - although the initial versions of lead-free solder caused considerable difficulties for engineers, the development in the field of the alloys themselves, as well as the fluxes used with them, meant that today RoHS-compliant soldering is no different (except temperature) from working with "lead tin". .

Lead solders vs. lead-free - similarities and differences
Soft soldering in electronic applications is based on connecting two elements (usually component leads with a PCB pad) using a relatively low-melting metal alloy. These conditions are met both by alloys based on tin and lead, as well as their lead-free versions (e.g. Sn99Cu0.7Ag0.3). In the case of the latter, however, the melting point is higher by about 30...40 o C, so the actual temperature of the tip, enabling effective soldering, must also be significantly higher. A different material also means differences in the appearance of solders - in the past, properly made connections could be recognized by their almost mirror surface, and any matting testified to problems (e.g. overheating of tin or lack of flux, and in extreme cases it could even be signaled by the so-called cold solders) . Today, the situation has changed a bit - the surface of lead-free solders reflects light slightly worse as standard, so more attention should be paid to the correctness of the soldering process itself. What's more - a higher tip temperature also means a greater risk of thermal damage to electronic components or a printed circuit board, so before switching to RoHS-compliant assembly, it is worth practicing working with modern solder on universal boards or self-assembly kits.
