Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".

Typical Applications
Solder is used alongside soldering irons, particularly in securing electrical components to integrated circuit boards. The solder melts easily when heated, and cools quickly, meaning it can be moulded to secure components in place in solder joints. The quick setting nature of solder means it can also be used for light brazing.
Because of its relatively low melting point, solder can be reworked easily by heating it to a melting point and using a solder sucker to remove it.
Solder is commonly used with SMD and through-hole components, with applications in repair, prototyping, and production.
FAQ’s
What is soldering used for?
Solder wire forms a connection between electronic components. Solder is heated, and melts using a soldering iron and then melts into a connection.
What is solder made of?
Typically, 60% tin and 40% lead. 60/40 is the most commonly used type of solder for hand soldering. Solder that is made of 63% tin and 37% lead. 63/37solder is also known as eutectic solder and is often preferred because it goes directly from a solid to liquid state when melted.
Types of solders?
Electronics solder – lead alloy, lead-free, silver alloy.
What metal cannot be soldered?
Stainless steel and high alloy steel unless pre-plated in a solderable metal.
