Automotive Electronics

ECU, ADAS, and zonal controllers must survive temperature cycles, vibration, and long service life. Ziitek supplies automotive-lean TIM documentation, gap pads for housing interfaces, and PCMs for power-dense stages — coordinated with your validation plan.

Solution overview

Ziitek supplies thermal interface materials, foam sealing, and selective heating across the automotive electronics stack — battery packs and BMS, inverters and e-drives, ADAS cameras and lidar, LED headlamps, e-pumps, and zonal controllers. IATF-aware documentation, PPAP-friendly lot control, and validated grades on EV programs let Tier-1 and pack customers second-source against imported pads with predictable resistance from −40 °C to 125 °C dwells.

Scene challenges

  • Zonal ECUs and e-drives pack more silicon into sealed housings, forcing soft gap materials to fill tolerance while keeping resistance predictable
  • Road vibration, shock, and -40 to 125 C dwells fret mechanical interfaces and pump out greases on inverter and motor-controller bondlines
  • ADAS camera modules and lidar pods sit millimetres from heat sources where outgassing or oil migration onto lens barrels and seal paths is fatal
  • Tier-1 and pack customers gate any TIM change on PPAP-aligned documentation, IATF change control, and banked-sample evidence before production

Solution value

  • TIF100 and TIF200 silicone gap pads plus TIF020AB two-part thermal gel fill cell, ECU, and inverter tolerance with tuned modulus and predictable resistance
  • TIC800K-2 phase change material (re-tuned on the customer's own controller bench at ~1.8 W/m K) and TIF100-K1 reinforced pads resist pump-out under road vibration
  • Thin, low-outgassing TIF pads and TIF-series gels in tape-and-reel format protect lens stacks and seal paths on ADAS cameras, lidar, and LED headlamps
  • PPAP-friendly data packs, IATF-aware ECN discipline, lot traceability, and banked samples ship with every grade for Tier-1 and pack-integrator audits

Where Ziitek materials sit in an automotive electronics platform

Modern vehicle programs concentrate silicon into sealed housings — zonal ECUs, e-axle inverters, ADAS sensor pods, BMS slave boards, lighting drivers — while keeping the same expectations on durability and EMC. Ziitek's portfolio spans the four jobs that show up across those housings: conduct heat between die and lid, fill manufacturing tolerance without aggressive clamp, seal the box against ingress, and selectively add heat where chemistry needs it.

The TIF, TIC, and Z-foam families that ship into power-tool, server, and consumer electronics platforms are the same families qualified on EV pack, motor, and inverter programs — the difference is the documentation discipline and the validation plan, not the chemistry shelf.

Key applications

  • Battery pack & BMS. TIF100 and TIF200 silicone gap pads bridge cells and cooling plates for cylindrical (18650 / 21700 / 46800), prismatic, and pouch architectures. Two-part thermal gels such as TIF020AB-02S flow into uneven cell-to-plate gaps on passenger-car packs where pad thickness alone cannot follow tolerance.
  • Pack sealing. Z-foam 800 is Ziitek's own closed-cell silicone foam, designed for pack housing seals. At 65 kPa it reaches 25 % compression; at 50 % compression it holds IP68 and IPX9K, and the material carries UL 94 V-0 (UL E331100) and UL 157 (MH66719) certifications. Reusable assembly keeps service costs predictable.
  • Low-temperature pre-heat. Kheat SP silicone-rubber heaters and Kheat PI polyimide film heaters add zoned pack pre-heat — for example a 35.2 V / 550 W PI heater partitioned into segments matched to cell-group thermal needs — improving cold-weather charge and discharge behaviour.
  • Motor, e-drive & inverter. TIF100 series pads, TIF020-19 single-part gel, TIF035AB-05S two-part gel, and TIF045-05 cover stator-to-housing, e-axle, and inverter power-stage interfaces. TIF100-K1 and dedicated capacitor pads sit on DC-link capacitors and IGBT modules where vibration and thermal cycling would defeat a grease.
  • ADAS, lidar & cameras. Low-outgassing TIF pads and thermal gels manage heat behind sensor PCBs without bleed onto lens stacks or seal paths. Tape-and-reel formats fit EMS line speed.
  • LED headlamps & lighting. Reinforced TIF pads with consumer-aesthetic cleanliness keep matrix-LED and projector modules within optical-stability windows over the life of the vehicle.
  • Electric oil pumps, e-transmissions, infotainment. The same families above, in thin and color-neutral variants, are deployed where housing tolerance and acoustic isolation matter as much as raw conductivity.

Recommended product paths

  • Silicone thermal pad (TIF) — primary gap-fill across pack, motor, inverter, ADAS, and lighting interfaces.
  • Thermal gel — single- and two-part formulations for irregular gaps, automated dispensing on pack and inverter lines.
  • Phase change material (TIC) — preferred for MOSFET stacks and high-power-density modules where pump-out and rewetting decide field life.
  • Silicone foam gasket (Z-foam 800) — pack housing seal, UL 94 V-0, IPX8/IPX9K with reusable service.
  • Film heating element (Kheat PI / SP) — zoned low-temperature pre-heat for pack and battery modules.
  • Thermal graphite sheet (TIR) — in-plane spreading in cockpit, infotainment, and slim sensor housings.

Reliability and documentation

Automotive electronics teams need predictable behaviour across −40 °C to 125 °C dwells and tens of thousands of thermal cycles, not just spec-sheet conductivity. Ziitek tunes filler loading and carrier chemistry on customer hardware so junction-to-case data on the customer's own controller, inverter, or BMS bench matches incumbents — even where rated bulk conductivity sits lower. Engineering change discipline, banked samples ahead of production switches, and PPAP-friendly data packages align with supplier-quality processes typical of IATF-certified Tier-1 and pack-integrator customers.

Reference programs

Ziitek materials are deployed on passenger-car battery packs (prismatic-cell programs at multiple Chinese OEMs, e-bike and two-wheel EV motor controllers), e-drive and motor platforms, traction inverters, and energy-storage packs that share the same thermal physics. The two-wheel EV motor controller case above is one example of the iterative, hardware-in-loop filler tuning that turns a portfolio grade into a qualified domestic second source against an imported incumbent. Tier-1 OEMs, pack customers, and motor/e-drive customers — referenced in Ziitek's industry roster — anchor the volume base that keeps lot control, change discipline, and global engineering support viable for new automotive programs.

  • Kheat PI and SP zoned heaters released on passenger-car and commercial EV programs for cold-climate pre-heat
  • IATF-aware ECN discipline, banked samples, and PPAP-friendly data packs ship with every grade for Tier-1 and pack-integrator audits

Material compliance & qualification

Ziitek automotive grades ship with RoHS, REACH, and SVHC declarations, UL94 V-0 flame rating, and lot traceability aligned to IATF 16949 supplier-quality processes. Z-foam 800 carries UL 94 V-0 (UL E331100) and UL 157 (MH66719) listings. Where customer programs require PPAP-aligned change control, banked samples ahead of production switches, and predictable behaviour across −40 °C to 125 °C thermal-cycle dwells, Ziitek's engineering team builds the documentation pack alongside the engineering sample shipment.

Conclusion

Ziitek's automotive-electronics portfolio is qualified against imported PCM pads on live motor-controller, pack, inverter, and ADAS programs, with verified resistance to pump-out, predictable performance across automotive thermal cycles, and PPAP-aware documentation. The TIF100 / TIF200 / TIF020AB / TIC800K-2 / Z-foam 800 family is the reference configuration we recommend for new Tier-1 and pack-integrator programs.

Material compliance & qualification

Ziitek lighting grades ship with RoHS, REACH, and UL94 V-0 documentation alongside long-cycle aging records that support TM-21 worksheets, L70 / L90 reliability models, and DLC / utility-rebate filings. Low-bleed, low-outgassing chemistry selection is verified for silicone optics, reflectors, and sealed lens stacks. Where customer programs require interface-resistance data appropriate to a specific stack, cut-to-width roll formats for linear MCPCBs, or qualification samples sized to EVT, Ziitek's application engineering supplies the data and the cut proofs inside the lighting-program cadence.

Conclusion

Ziitek's LED-lighting portfolio is qualified against the same chemistry families that ship into industrial photonics and high-power emitter cooling, with low-bleed, color-stable, low-outgassing discipline appropriate to silicone optics and IP-rated castings.
