RoHS
The information will be relevant for those of our customers who plan to supply their finished electronic devices to the European Union market. In 2003, the European Union adopted the RoHS (Restriction of Hazardous Substances) directive. This directive defines the maximum possible content of 10 substances in goods produced in the EU or supplied to the EU from the list below:
The restriction on the use of nine substances from the list did not affect electronics and electronic components manufacturers in any way, but the restriction on the use of lead became a real headache. Prior to the adoption of this directive, lead was the main material in electronics, solder pastes and solders contained more than 60% lead, this is due to the fact that lead has several advantages, namely:
Going lead-free has been a real challenge for many contract electronics manufacturers because it has meant not only higher solder costs, but also upgrades to production equipment as lead-free solders are more refractory.
What is the way out for companies that want to supply their electronic devices to the EU market? First, you need to choose the right solder. Secondly, find a supplier with reasonable prices. Thirdly, to purchase a test batch of solder or solder paste and send it to the laboratory for analysis, this is very important, because the maximum lead content according to RoHS is 0.1%. Fourth, after confirmation, purchase the required batch of solder and transfer it to the manufacturing company (provided that they have suitable equipment and experience in using lead-free solders). Or contact a manufacturing company with experience in this matter, which will do it all for you on a turnkey basis.

Prior to the adoption of this directive, lead was the main material in electronics, solder pastes and solders contained more than 60% lead, this is due to the fact that lead has several advantages, namely:
- low melting point;
- comparatively high conductivity
- economy.
