Electronics Design & Manufacturing Workshop 25: 10 years of RoHS
30-09-2016 :: Kapeldreef 75, 3000 Leuven

Organizer: imec

10 years ago, July 1st, 2006 to be exact, the EU directive 2002/95/EC RoHS (Restriction of Hazardous Substances in electrical and electronic equipment) came into effect. The goal of this directive is to reduce the use of six hazardous materials in the electronics industry : Pb, Hg, Cd, Cr6+ and the flame retardants PBB and PBDE.
The electronics industry started preparing for this directive well in advance. It proved to have an impact to the operations of the electronic industry as well as on electronics quality and reliability, larger than what some expected.
Mainly the use of lead-free soldering processes, and the subsequent higher soldering temperature, induced a change in the choice of solder alloys and flux formulations, PCB substrate material, board and terminal finishes, component mold compounds and lead to more thermal stress to the components during soldering. It also changed the way we look at reliability of electronic modules. Even some of the well-established design rules required revision.
On the other hand, the requirement of traceability of RoHS compliancy over the total supply chain was a logistical challenge, both for the component suppliers, for the manufacturers ERP systems and for the quality departments in the companies. As an extra complexity, the exemptions for some sectors meant that most manufacturing companies had the need to run both lead-free and SnPb solder processes simultaneously (some still do).

During this first workshop, we will focus on legislation and on the material aspects of the RoHS story. Below you find a short overview of the presentations that will be given during the workshop.

  • The future of RoHS, what is still coming up?
    In the last ten years, we got used to RoHS. Even the recast of 2011 did not fundamentally change the way RoHS works. But will this also be true for the next ten years? And what about other EU policies coming up? Let us take a look at the EU negotiation table.
    Johan Daniëls : Attache FOD Leefmilieu, Afdeling Productbeleid.
  • Soldering Materials and chemistry : evolution in the past 10 years of RoHS and future challenges and trends.
    Steven Teliszewski : Interflux electronics
  • Conductive adhesives as alternative for solder, or is there more ?
    Speaker : to be confirmed
  • Lead-Free soldering : a challenge for PCB base materials
    Adolf Sommer : Manager of Application Engineering : ISOLA group

The coffee is ready at 13:30, the presentations start at 14:00. At 17:00, we invite you to network, facilitated with a drink and a snack.
