DOWSIL TC-5888 thin-bondline thermal interface compound
Dow · Material properties and interface engineering
- Purpose
- Gaps, coverage and bond-line thickness can raise contact resistance in processor or power-module thermal interfaces. TIM performance needs comparison under the actual pressure and surface geometry.
- Technical approach
- DOWSIL TC-5888 is a one-part, non-curing, solvent-free thermal compound that can be screen printed to fill contact gaps. Thermal resistance needs evaluation alongside pressure, thickness and application method.
- Scope of use
- Dow lists electronics applications such as MPUs and power modules, and includes it on its computing-systems page. The intended die/lid/heatsink interface and material compatibility need confirmation.
- Limitations and open questions
These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitationsThe published resistance and thickness values have a specified pressure; actual flatness, warpage and coverage matter. The reviewed pages do not establish directly usable pump-out/dry-out lifetime conditions for the target stack.
What to prepareBLNKK suggests preparing contact materials, dimensions/topography, gaps and clamping pressure, dispensing/printing coverage, target thickness, and initial versus aged thermal-resistance results.
Confirm with the supplierConfirm the intended interface, material compatibility, recommended application/pressure window and resistance test method. Request relevant cycling or long-term pump-out, dry-out and migration data, and confirm any removal/reapplication procedure.
- Public evidence
- The page lists 5.2 W/m·K conductivity and typical properties of 20 µm bond-line thickness and 0.05°C·cm²/W resistance at 40 psi. These condition-specific values do not guarantee performance in an arbitrary assembly.
