Consumer ElectronicsThermal Materials & Stack-up Support

Air gaps between hot components and heatsinks act as an insulator (air ~0.026 W/m·K).
Sheen TIMs fill micro-gaps, reduce interface resistance, and stabilize device performance.

Typical Thermal Challenges in Compact Devices

Hotspots on SoC/CPU/GPU/PMIC under tight Z-height and limited heatsink volume.

Tolerance stack-up and height differences requiring compliant pads or dispensable gels.

Production constraints (rework, cleanliness, automation, yield) in high-volume assembly.

Tip: Share your gap (min/max), power map, and target temperatures. We will recommend material type, conductivity range, thickness window, and a sample plan.

Where Sheen TIMs Are Used

Typical consumer electronics interfaces that benefit from air-gap elimination and stable thermal contact.

Smartphones

Processor/shield can / power stages. Gels help handle chip height differences and reduce assembly stress.

Laptops & Handhelds

CPU/GPU thermal modules. PCM and thin interfaces enhance wetting and reduce thermal resistance at operating temperatures.

Routers & Networking

SoC and power modules. Pads provide stable thickness and fast placement in production.

SSD & Storage

Controller/NAND coupling. Pads support consistent contact and reliability for compact enclosures.

Consumer Electronics

Choose based on gap, pressure, and silicone restriction.
and production method (placement vs dispensing/printing).

Consumer Electronics

Flexible pads for defined gaps and tolerance stack-up. Options may include reinforcement films (e.g., fiberglass/PI) and adhesive options depending on assembly needs.
Thermal conductivity: 1.5–15.0 W/m·K
Thickness: 0.3–10.0 mm

Consumer Electronics

Routers, SSD modules, graphics thermal modules, and other compact electronics where fast placement is preferred.
Interface Goal Notes

Consumer Electronics

Designed to reduce risks from silicone oil bleed / low-molecular siloxane volatility that may contaminate sensitive parts (e.g., optics/camera or HDD environments).
  • Thermal conductivity: 1.0–6.0 W/m·K
  • Thermal conductivity: 1.0–6.0 W/m·K

Consumer Electronics

  • Optical/camera modules where condensation can affect clarity
  • HDD/storage where oil bleed can attract dust and impact read/write reliability
  • Silicone-sensitive electronics requiring cleaner long-term environment

Consumer Electronics

Fluid-like TIM with strong wetting for micro-roughness. Suitable for dispensing equipment, screen printing or spreading, supporting automated production and large thickness variation.
  • One-part series (SE20–SE100): 2.0–10.0 W/m·K
  • Two-part gel: cures to elastomer, helps maintain required thickness

Consumer Electronics

Smartphones and smart speakers with multiple chips and height differences; gel reduces assembly stress and improves contact.

Process-friendly: dispensing / printing enables consistent thickness control and scalable yield.

Consumer Electronics

Reference Matrix

Interface Recommended Material Engineering Notes
SoC → Vapor chamber/heatsink PCM / Thin Pad Prioritize low thermal resistance; confirm contact pressure & flatness.
PMIC / RF module → shield/frame Soft Pad / Gel Manage tolerance stack; avoid over-compression damage.
Small module bonding Thermal Tape / Adhesive Choose reworkable tape vs permanent adhesive based on service strategy.
Battery / charging IC → chassis Pad / Gel Consider cycling reliability; validate at sustained load.

NDA available. We can share TDS, compliance declarations, and a sample plan after your request.

Validation Checklist

A simple, repeatable approach for engineering qualification. Keep documentation consistent for procurement review.

Etiam erat velit scelerisque in dictum non consectetur. Nisl purus in mollis nunc sed id semper. Cras fermentum odio eu feugiat pretium nibh ipsum.

Gap Mapping & Tolerance

Measure the minimum and maximum gaps across units. Select compliance/hardness to cover real distribution, not nominal values.

Validate junction/case temperatures at sustained load. Watch for interface pumping or contact loss over time.

Run thermal cycling, storage, and long-duration stress as needed. Confirm stable contact and no excessive migration.

Confirm placement, cleanliness, rework, and automation suitability. Define a QC plan for incoming inspection.
