Calendar of Events
The Ohio Valley chapter of the SMTA would like to invite you to this exciting educational event.
WHEN: Tuesday, October 26, 2004
WHERE: Radisson Hotel Columbus - Worthington, Worthington, OH
TIME: 9:00AM - 2:30PM
TOPIC: "Materials, Processing, and Reliability of Lead Free Solder Solutions"
INSTRUCTOR: Daniel Baldwin, Engent, Inc./Georgia Institute of Technology
COST: $100 SMTA Members/$160 non-members
This course will present a review of the materials, processes and reliability of lead free solder solutions. The course will focus on materials selection based on environmental impact, legislation, and market trends. It will also highlight lead free solutions for component lead terminations, connectors, and PCB surface finishes. Process implementation strategies and issues from printing wave soldering and rework will be presented. A discussion on backwards compatibility of lead free solder will also be included. Reliability and qualification of lead free solder solutions across multiple industrial efforts will also be reviewed.
Although no country has banned lead solder completely, the European Union is calling for a phase-out in the use of the toxic substance in the design of new products. Large OEMs have lead on their â€˜restricted listâ€™ and are currently seeking alternative solutions. Waste from electrical and electronic equipment (WEEE) contains many substances that may pose a threat to human beings and the environment, making it urgent to involve the producers and to change the waste management systems. The European Commission has adopted a proposal for a European Directive on WEEE. Producers of electrical equipment will be responsible for take-back, reuse, and disposal of the product. When customers buy a new product, they can return an old product of the same type, free of charge. Producers are also obligated to provide information on the material content of the product when requested by pre-treatment operators.
Lead-tin solder is inexpensive and readily available. It has a low melting point and excellent thermal fatigue resistance in addition to good electrical and thermal conductivity. Lead-tin solder has rapid and complete wetting, is easily repaired, resists corrosion, and gives fast self-alignment during reflow. A simple drop-in replacement alloy with a melting point that is relatively close to that of Pb-Sn solder is in great demand. The lead-free solder must perform comparably for manufacturers to readily replace the standard soldering methods used in electronics assembly.
Who Should Attend
Individuals associated with low cost surface mount assembly and low cost electronics packaging are encouraged to attend, specifically, the following: ï‚· Managers. Knowledge gained through this course will allow managers to make informed decisions about the technical feasibility, implementation factors, performance benefits, reliability, and costs of implementing lead free solder processing technology. ï‚· Engineers. Manufacturing, quality, design, and packaging engineers in integrated circuit, equipment, materials, and system design who are challenged to solve tomorrowâ€™s process solutions and next generation packaging problems. ï‚· Procurement. Course materials we introduce purchasing and supply chain management personnel to the key issues and sourcing concerns that should be addressed in the early phases of lead free solder assembly production.
