Stuck in the Middle?
...Cross the Lead-Free Divide with Henkel's Multicore MP218
With the European lead-free directives now less than a year away, electronics manufacturers everywhere are finding out exactly what it takes to comply.
But what if you don’t have to adopt lead-free just yet? Can you sit back and observe from a distance? The answer is, quite simply, not at all.
Problem: Transitioning tin-lead to lead-free
Unfortunately, conventional tin-lead materials are not compatible with the new lead-free device finishes. However, as part of the global transition to lead-free, component manufacturers are switching to lead-free finishes – sometimes without even changing the part number.
With such a diversity of conventional processes in widespread use, tin-lead solder is likely to interact during reflow with one or more lead-free finishes, causing subtle changes in the mechanism of joint formation. The higher temperatures required by lead-free alloys means that a standard tin-lead profile will not enable proper reflow. Incomplete wetting is a typical consequence, often leading to problems such as opens and voiding, and tempting assemblers to adjust the reflow profile, at the risk of exceeding the capability of most tin-lead pastes. So whether you need to go lead-free with your products and market sectors or not, you won’t necessarily get the choice.
Solution: Multicore MP218
Henkel has formulated Multicore MP218 to address this problem directly. Using raw materials, activators and other components similar to those used in next generation lead-free solder pastes, MP218 is specifically intended to allow tin-lead processes to cross the lead-free divide. Extra activity and a wider process window are designed to put you back in charge of your assembly.
Thousands of manufacturers around the world already rely on Henkel’s solder formulations. With internationally recognised technical expertise, industry knowledge and comprehensive materials solutions, Henkel is best-equipped to meet every challenge presented by today’s changing market needs.
