Silicones for Electronic Assembly - Principles and Applications

Silicones are broadly used in electronics assembly to prolong the life of modules and enhance safety due to their intrinsic physical properties such as dielectric strength, heat stability and flame retardancy. Silicone materials can either protect, bond and/or conduct heat of electronics parts in versatile high value applications such as automotive, aerospace or communication.
This Webinar will highlight the specific characteristics and properties of silicone polymers in electronics. The Webinar contains case studies with good practice recommendation to illustrate some important material properties, such as (1) an efficient moisture protection of modules, (2) management of the coefficient of thermal expansion and (3) surface preparation to improve adhesion performance.
The different forms and chemistries of silicones commercially available to serve electronic applications are reviewed (1) Adhesives, (2) Encapsulants / Gels, (3) Conformal Coatings and (4) Thermally Conductive materials. Their similarities (e.g., the need for developing a strong interfacial contact with the substrate to assure protection) as well as their differences (e.g., shock absorbing ability) is explained.

Objectives:

• Learn the advantages and limitations of Silicones in electronics
• Be able to understand the different type of cure chemistries commercially available
• Learn best practise for a reliable usage of silicone materials
• Gain sufficient knowledge to make a successful material selection
• Be able to identify a suitable silicone material in respect of form, physicals properties and processability for a variety of electronics applications
