There are many kinds of solder bars, which can be divided into lead solder bars and lead-free solder bars from the lead content. As the name suggests, leaded solder bars contain lead, and the lead content accounts for a large part. However, lead-free solder bars are not lead-free, but if their content is below 1000PPM, they can be called lead-free solder bars. That is to say, the lead content in lead-free solder bars is within 0.1%, but we generally regard it as lead-free solder bars without lead.
