LEAD-CONTAINING SOLDER PASTE
Most industries switched to lead-free solder pastes when the RoHS Directive came into force in 2006. There are only a very few exceptions in which lead-containing solder pastes may be used. Exempt are, for example, safety-relevant components in the automotive, aviation, military, and medical engineering industries, where the safety of people has priority. There are suitable long-term tests for lead-containing solder joints that show that the requirements in these industries can be met.
As more and more applications use lead-free alloys, the production volumes of lead-containing solder pastes have been significantly reduced. We have adapted our range of lead-containing solder pastes so that we still have one type available in stock.
Advantages of lead-containing solder paste
- High elasticity of the alloy
- Low melting temperature range
- Broad melting range (tombstoning is prevented)
- Cost-efficient
- Quick wetting
- No whisker formation
