RoHS (Restriction of Hazardous Substances) is a European Union directive that restricts the use of lead, mercury, cadmium, chromium (VI), PBBs, and PBDEs in electrical and electronic equipment as of July 1, 2006. Like other semiconductor companies, we use tin/lead solder (plating) for the surface finish of leadframes.
What is RoHS solder made of?
Lead-free solder materials usually comprise of lead-free solder and flux. Lead-free solder can be made from different compositions (% weight) of metals, such as Tin (usually the main element), Silver, Copper, Antimony, Bismuth, Cobalt, Nickel, Indium, Zinc, Germanium, and rare earth elements.
Is 63 37 solder RoHS compliant?
This product contains lead. It can be used to repair lead-free devices, but they will no longer be ROHS compliant. Solder with a rosin flux core is a favorite for rework. Leaded Solder Wire 63/37 Tin/Lead no-clean 4oz.
Why is RoHS important?
The goal of RoHS (Reduction of Hazardous Substances) is to reduce the environmental effect and health impact of electronics. The legislation’s primary purpose is to make electronics manufacturing safer at every stage of an electronic device’s life cycle.
What is solder made of now?
Solder is a metal alloy usually made of tin and lead which is melted using a hot iron. The iron is heated to temperatures above 600 degrees fahrenheit which then cools to create a strong electrical bond.
Does RoHS have flux?
flux have compliance with all the requirements of RoHS directives. RoHS: Restriction of Hazardous Substances [ lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE).]
What is the strongest type of solder?
A 60-40 solder (60% tin, 40% lead) is the most expensive, but it makes the strongest bond and is easiest to work with because of its low melting point. Less expensive 40-60 solder is more difficult to use.
