    About the Lead Free-RoHS Course

    THIS RoHS COURSE DESCRIBED BELOW, HAS BEEN MERGED INTO SMT-BGA-BTC COURSE SINCE MAJORITY OF THE COMPANIES HAVE MADE THE CONVERSION TO LEAD FREE.

    THOSE COMPANIES WHO ARE STILL USING TIN-LEAD (e.g. Military), YOU STILL NEED TO DEAL WITH LEAD FREE COMPONENTS ESPECIALLY BGAs.

    THE SMT-BGA-BTC COURSE ALSO DEALS WITH ALL THE TECHNICAL ISSUES RELATED TO DESIGN AND ASSEMBLY OF MIXED ASSEMBLY, ALSO KNOWN AS BACKWARD COMPATIBILITY WHERE LEAD FREE COMPONENTS ESPECIALLY LEAD FREE BGAs ARE SOLDERED WITH TIN-LEAD SOLDER PASTE.

    IF YOU THINKING OF CONVERTING FROM YOUR CURRENT PROCESS OF TIN LEAD TO LEAD FREE, THIS RoHS COURSE DESCRIBED BELOW CAN BE OFFERED AT YOUR SITE. IN ADDITION, WE CAN TOTALLY CUSTOMIZE THIS COURSE TO MEET YOUR SPECIFIC NEEDS. YOU CAN USE THE DESCRIPTION BELOW (A TWO DAY COURSE) AND ALSO THE COURSE DESCRIPTION OF SMT-BGA-BTC COURSE TAUGHT IN BEAVERTON (OR YOU SITE) AND DEVELOP YOUR OWN COURSE OUTLINE. WE CAN WORK WITH YOU TO DEVELOP A CUSTOMIZED COURSE OUTLINE FOR ONE TO FIVE DAY COURSE.

    HERE IS THE COURSE DESCRIPTION OF RoHS COURSE:

    Is lead free also on your mind? It should be even if your industry may be temporarily exempt. Lead free impacts almost everyone in the electronics industry - from supplier of component, board and materials like paste and flux to manufacturers and users of electronics products and equipment including military and medical industry.

    This is not a theoretical course. We will also show you how you can resolve the business and technical issues (principles as well as practice) for an effective implementation of lead-free at lower cost and higher yield.

    Most lead-free solders have higher melting points than currently used tin-lead solders and thus pose a challenge for all board assembly processes, including rework. We will also cover use of low temperature lead free solders that address some of the technical issues in high temperature lead free alloys. They are becoming popular in many applications. As opposed to one tin-lead composition we have been used to, in lead free you may have to deal with multiple lead free BGA ball compositions with different melting points on the same board.

    We will discuss the details of RoHS and WEEE legislation including the status of exemptions for various industries. In addition to discussing the details of in-house lead free implementation, we will also discuss technical issues when dealing with Contract Manufacturers.

    We will provide you all the technical details including wave and reflow profile development, paste selection, inspection and rework using both conventional and laser. We will also provide you the status of legislation banning lead around the world including Europe, Japan, China and USA and how you can improve your companyís profile and benefit from this disruptive technology.

    Objectives of this Course:

    • Understand the current status and driving forces for RoHS & lead-free conversion
    • Understand how to do a detailed RoHS compliance audit of a supplier or be ready for RoHS audit by a customer
    • Understand complex technical, cost and business issues in RoHS & lead-free implementation
    • Understand the pros and cons of various laminate materials and surface finishes for lead free products.
    • Understand metallurgy of lead free solder to enable selection of appropriate lead free surfaces finishes, solder alloys, soldering and rework processes and equipment
    • Understand how to implement RoHS & lead-free technology in your products and manufacturing processes either in-house or at a subcontractor including dealing with the technical challenges of mixed technologies
