Soldering is a process whereby similar or dissimilar metals are joined using a soldering alloy that typically includes Tin combined with silver, lead, copper, antimony, bismuth, indium or other alloys. Soldering covers a temperature range of 60 – 445°C. Most solders for electronic and other purposes are an alloy of lead (Pb) and tin (Sn). Some solders also contain Silver (Ag), and others are lead free. Repeat this on both sides of the heat tape. Next- Hold the tinned end of one of the wires on one side of the tinned heat tape. Now gently press down on the wire end, the wire and solder puddle on the heat tape will heat up and as soon as you see all the solder flow together remove the iron. The tape is on the rack itself, not in the tub. Between the snake and the tape is the bottom of the tub and bedding; that is unless the snake pushes it out of the way which a few of mine have done but the bottom of the tub is thick enough to keep the snakes from being burned. Features are Superior adhesiveness to applications with high repulsive force such as FPC bending. High shard removal processability/usage during die-cutting process. Can be soldered with the release liner attached. (Heat resistant release liner.
