Lid Seal Adhesives
Low Stress, Highly-reliable Sealants for High-Performance Devices
DuPont Electronics & Industrial portfolio of silicone lid-seal adhesives are designed to manage the highly stressful operating environments of today’s advanced semiconductor devices, resulting in more reliable, long-term device performance critical in today's high-performance computing, mobile and automotive electronics applications.
Available with various modulus and curing conditions to improve productivity and meet a wide range of customer needs.
Lid Seal features:
- Low voiding for more reliable heat transfer
- Thixotropic for easy dispensing
- Low modulus ensures outstanding stress relief
- Fast or snap cure for shortened processing time, resulting in increased productivity
- High performance sealant for protecting sensitive components against moisture and contamination
- Strong adhesion to commonly-used microelectronics substrates
What are Lid Seal Adhesives?
Lid seal adhesives are used to protect sensitive components against moisture and contamination. Today’s high functioning advanced packaging requires higher processing and operating temperatures that can damage sensitive electronic products. Lid seal adhesives can complement thermal interface materials (TIMs) to provide an effective stress-relief solution for managing the heat of high-performance devices through the heat spreader.
Today’s Advanced Packaging, Assembly Processes
Our high-purity lid seal adhesives meet the demanding criteria of today’s semiconductor packaging and assembly technologies. They provide excellent primer-less adhesion to a wide variety of substrate materials and perform reliably at high temperature, fast curing processing. They also perform well in stringent reliability tests, such as temperature cycling or other moisture sensitivity level testing applications.
