High Reliability Lean Lead-free SMT Manufacturing

HIGH-RELIABILITY LEAN LEAD-FREE SMT MANUFACTURING

Environmental and economic demands have made electronic manufacturing more challenging than ever. To be competitive In this day and age, the electronics assembler has to be both Lean and Green. A daunting task perhaps, but it can be accomplished.

Although many electronics manufacturers are still in transition to the production of RoHS compliant, Lead-Free products, sufficient experience has been gained throughout the industry to move the “science” of Lead-Free design and manufacturing from the investigation phase into at least the first levels of optimization. This must be accomplished in a manner that facilitates the manufacturer’s competitiveness.

This course teaches the essentials of lean manufacturing as they apply to SMT electronic assembly. Rather than generalizations, specific applications of lean principles are presented and discussed. Not surprisingly, these lean practices and methodologies compliment and enhance the effectiveness of lead-free manufacturing.

The workshop also presents an objective examination of the current state of the industry in applying and optimizing Lead-free materials, solder, equipment, and processes.

The course examines what the variations in lead-free alloys mean to the electronic assembler at the process and logistics level and choosing specific alloys to enhance reliability for individual applications. The pros and cons of specific available solder alloys are discussed and how these can be utilized to minimize costs, assembly problems such as copper erosion and to enhance the reliability characteristics of certain types of products including handheld devices. The impact upon printing, placement, reflow and inspection will be examined and the situations confronted by both OEMs and CEMs will also be discussed.

The final part of the course will contend with the implications of lead-free on the SMT assembly process with the most current research and data being presented. Interactions with substrate finishes and components will be discussed as will the far-reaching implications and process adaptations that must be made to accommodate no-lead soldering. Conversion to RoHS Compliant, Lead-Free products and manufacturing involves a significant effort in time, materials, and personnel. This course will demonstrate some of the OPPORTUNITIES to use this conversion to create a more efficient and “Lean” production environment with higher yields and less defects.
