Material Selection & Integration
01 · Contamination sensitivity
AF Series pads are silicone-free / siloxane-free and help eliminate the risk of silicone oil bleed in sensitive assemblies.
- Check silicone sensitivity before ranking materials by W/m·K.
- Evaluate compatibility with optics, sensors and precision electronics.
- Confirm electrical insulation requirements for the selected grade.
02 · Thickness, softness & pressure
The series covers 0.25–5.0 mm across grades. AF1000 is available in 1–2 mm; AF800 covers 0.5–5.0 mm by quotation.
- Start with actual gap, tolerance stack-up and allowable assembly force.
- AF100–AF800: 50 / 70 ± 5 Shore 00. AF1000: 50–65 Shore 00.
- Validate compression and contact quality in the actual assembly.
03 · Supply & production integration
The existing series specification lists 200 × 300 mm sheets and die-cut parts. Confirm the selected model, thickness and project-specific format before ordering.
- Self-adhesive behavior supports placement and rework.
- Confirm thermal, insulation and UL94 V-0 requirements for your model.
- Review required RoHS, Halogen-Free and REACH documentation.
04 · Storage & qualification
Store in a cool, dry, well-ventilated place away from open flames. The existing series information lists a 12-month shelf life.
- Lock model, thickness, format and compression condition before volume supply.
- Confirm handling, packaging and current technical data for the selected grade.
- Qualify thermal performance and compatibility in the intended use.
Applications & Recommended Starting Points
For higher thermal demand, AF600, AF600G and AF1000 are strong evaluation priorities. AF1000 is the highest public grade at 10±1 W/m·K for 1–2 mm gaps; AF800 is available by quotation when the gap needs the wider 0.5–5.0 mm window.
Optical communication
Evaluate AF600 / AF600G / AF1000
For silicone-sensitive optical modules and communication interfaces. Match the candidate grade to the actual gap and allowable contact pressure.
AI data centers & servers
AF1000 · 1–2 mm interfaces
The highest public grade for data centers, network equipment and servers when a 1–2 mm thickness window fits.
Sensors, cameras & medical electronics
AF300–AF600G · Evaluate by gap
For precision electronics that prioritize silicone-free materials and electrical insulation.
Storage & industrial control
AF500 / AF600 / AF600G; AF1000 where suitable
Screen hard drives, SSDs and industrial assemblies by thermal load, thickness, compression and interface geometry.
For broader 0.5–5.0 mm gaps requiring an 8 W/m·K class, request an AF800 quotation. Pricing, MOQ, technical data and die-cut formats are confirmed per project.
Datasheets & Downloads
AF1000 is the highest public grade with a released datasheet. AF800 is quotation-only: its 0.5–5.0 mm thickness window and die-cut formats are configured per project, so pricing, MOQ and technical data are confirmed on request.
Frequently Asked Questions
Q1. Why is contamination risk discussed first?
Because the AF Series is explicitly positioned as a silicone-free thermal pad family that is free of siloxane and intended to help eliminate silicone oil bleed in sensitive assemblies.
Q2. Why compare thermal impedance instead of only conductivity?
Because actual thermal performance depends on conductivity, thermal impedance, thickness, compression, and real assembly structure. W/m·K alone is not enough for model selection.
Q3. Why is thickness discussed separately from conductivity?
Because thickness determines whether the pad can properly bridge the actual gap without excessive stress. A higher-conductivity model is not automatically the best fit if the thickness and compression window do not match the assembly.
Q4. Which AF models are better starting points for higher thermal demand?
Based on the current public series page, AF600, AF600G and AF1000 are the stronger starting points when higher thermal performance is required. AF1000 adds a 10±1 W/m·K class for 1–2 mm interfaces; AF800 is a quotation-only grade for 0.5–5.0 mm gaps.
Q5. What production forms are available?
The current public page lists 200 × 300 mm sheet supply and die-cut parts, with customized packaging according to customer requirements.
Q6. What applications are explicitly listed on the current public page?
The current series page explicitly lists data centers, automotive sensors, AI devices, fiber optic communication systems, industrial control equipment, hard disk drives, and medical devices.
