Oven Temperature Profiler‑Applications in New Energy Vehicle Manufacturing
New energy vehicle inverters, BMS, vehicle‑mounted controllers and power semiconductors are automotive‑grade products with extremely strict requirements for soldering, curing and sintering temperatures. The oven temperature profiler serves as core equipment for thermal‑process quality control.
1. SMT Reflow Soldering for Vehicle‑mounted Electronic Boards (BMS, VCU, Domain Controllers)
Collect real‑time temperature profiles of PCBs, BGA chips and connectors. Control heating slope, soaking time, peak temperature and cooling rate to avoid cold joints, voids and thermal damage to components. Comply with IATF16949 automotive‑grade traceability requirements. Generate process reports for factory audit and filing, ensuring long‑term reliability of vehicle‑mounted circuit boards under vibration and extreme temperature conditions.
2. Soldering & Brazing of IGBT / SiC Power Modules
For core inverter components including IGBT and SiC power devices, multi‑channel temperature measurement monitors temperature differences across chips, solder layers and substrates during chip brazing and DBC substrate reflow soldering. Prevent solder voids and thermal‑stress cracking. Poor soldering of power modules may directly cause vehicle power failure. The profiler safeguards the service life and safety of high‑voltage power devices.
3. Manufacturing Processes for Power Battery Components
- PCBA reflow soldering of battery protection boards: Control temperature deviation caused by high‑thermal‑conductivity aluminum substrates. Prevent failure of protection‑board soldering and eliminate risks of over‑charging or over‑discharging of batteries.
- Curing of structural adhesive & potting compound: Monitor temperature profiles inside curing furnaces to achieve full curing for BMS and module potting, improving moisture and shock resistance.
- Heat‑treatment for busbar welding of battery modules to verify thermal‑process consistency.
4. Coating and Baking Curing of Vehicle‑mounted Parts
For charging‑pile housings and automotive structural parts with powder coating, track baking temperature profiles to guarantee coating adhesion and avoid peeling, enhancing weather resistance of components.
5. Digital Production & Automotive‑grade Quality Control
- Compare set furnace temperature against actual workpiece temperature, offset temperature drift caused by furnace aging and uneven airflow to stabilize mass‑production yield.
- Full‑data storage and MES‑system integration realize full‑process traceability to meet audit standards of automotive OEM suppliers.
- Optimize furnace‑zone parameters to cut energy consumption and reduce scrap for cost‑efficiency improvement.
