LED ASSEMBLY · LOW-TEMPERATURE-CURING EPOXY
See real bonding demonstrations of PC lenses fixed to aluminum substrates using a one-component, low-temperature-curing epoxy adhesive.
The application
LED backlight assemblies require lenses to be fixed to their supporting substrates. For this application, XINCHENG supplied a heat-curing epoxy solution for bonding PC lenses to aluminum substrates.
The selected adhesive is part of our LED Backlight Fixing Adhesive family. The one-component format requires no mixing, while the grade and curing process can be selected to suit the customer’s assembly requirements.
Demonstrated curing conditions: 85°C for 5 minutes
This schedule applies to the samples demonstrated here. It is an application example, rather than a fixed specification for every grade in the product family. Confirm the heating conditions for your materials, adhesive amount, assembly geometry and equipment.
Watch the bonding demonstrations
The following clips show actual sample handling. They are presented without audio and without claims of standardized test compliance.
Flexing, handling and close-up view
View the bonded lens strip during manual handling and flexing, followed by close-up footage of the assembly.
Pull demonstration
A bonded sample is subjected to a manually applied pulling force using a measuring tool. No numerical bond-strength value is reported.
Drop demonstration
A bonded sample is dropped onto the floor. The clip provides a visual demonstration; drop height and a standardized impact rating are not specified.
What this application demonstrates
- A practical PC lens-to-aluminum bonding application for LED backlight assemblies
- Use of a one-component epoxy with a low-temperature, short-duration heat-curing schedule
- Actual bonded samples shown during pull, flexing and drop demonstrations
These demonstrations apply to the samples and conditions shown. They do not establish a standardized tensile strength, drop rating or long-term durability specification.
