This product works well for circuit boards and applications in tiny areas. Its small size rather than buying a larger spool makes it easier to handle. The alternative 64-025 lead free solder requires higer temperatures and reportedly does not work well with the 15 watt Radio Shack iron. (See reviews of that iron. I recommend that iron, also.) The quetion here is the health danger and legal restrictions on lead verses ease of use and possible shorting over time of non-lead solders on tiny circuits where wires are very close. Also, the greater heat required by non-lead products might harm heat sensitive parts during assembly. However, for manufacturing applications, non-lead solders are preferred due to restrictions on lead [See ROHS compliance] in some countries. Where parts may move during assembly, consider a 63/37 solder but note that it may take more heat.
