Customer Testimonials
Leader in polymer thermal conductive material modification technology
Must we use Non-Silicone for optical modules?
Absolutely. Standard silicone causes outgassing, leading to lens fogging and signal loss.
-
Zero Outgassing & Migration
-
Ultimate reliability for LiDAR & Transceiver
Is a softer thermal pad (Shore 00 30) always better?
It depends on your design. Harder pads (Shore 60) can be ultra-thin for perfectly flat surfaces. Softer pads (Shore 30) are essential for filling irregular gaps and large tolerances.
-
Custom Hardness Available
-
Zero Localized Hot Spots
Thermal Gel or Pre-cut Pads for mass production?
Gel wins for complexity. Pads are great for simple, single components. But for complex boards with varying heights, automated gel dispensing eliminates the need for multiple pad SKUs.
