FAQ

Frequently asked questions about solutions and customization

Which businesses suit which customers?
Thermal flow-channel cleaning equipment serves automotive thermal-management makers and AI liquid-cooling integrators; intelligent assembly lines serve automotive components, sensor and electrical-parts makers; compute-board test fixtures serve AI server and GPU module makers. All three are custom designed and built.
Are the machines standard products or custom-built?
Everything is tailored to the customer's products and process. Thermal cleaning uses a standardized process platform configurable per workpiece and takt; assembly lines and compute-board test fixtures are designed from standalone stations to full lines as needed, with quick multi-variant changeover.
What is the process from inquiry to delivery?
A five-stage closed loop: discovery, design, prototype, delivery, and support. Standard solutions deliver in about 60 days; complex turnkey lines are assessed by project complexity, number of processes and customization needs.
Does the equipment meet automotive-grade quality requirements?
Equipment is designed and built to automotive-grade quality requirements, with key-station data traceability, poka-yoke, inline inspection and EOL testing, and MES integration — supporting customers' IATF 16949 audit requirements for data traceability and quality control.
How do we get a proposal or quotation?
Submit your requirements via the /contact page or call +86 13451730284. We respond within 24 business hours; our engineers review product drawings and takt targets and then provide a custom proposal and quotation.
To which standard is thermal flow-channel cleanliness assessed?
Particle cleanliness is assessed to ISO 16232 / VDA 19.1 for flow-channel parts such as cold plates, oil coolers, manifolds and flow plates. The process covers integrated cleaning, air-blow, vacuum drying and cooling, with multi-stage filtered media recirculation. The exact cleanliness class follows the customer's drawing and acceptance specification — and note that ISO 16232 is a component-cleanliness standard, not to be confused with cleanroom classification (ISO 14644) or hydraulic fluid contamination (ISO 4406).
Can an intelligent assembly line integrate with our MES and traceability requirements?
Yes. Lines provide automatic key-station data capture, batch and per-unit traceability, poka-yoke, and inline inspection and EOL testing, with MES integration — supporting customers' IATF 16949 audit requirements for data traceability and quality control. Key-station process capability can be designed and validated to a Cpk ≥ 1.67 target.
Does the AI board-test business include software or algorithm development?
No. That business covers the hardware layer only: mechanical design, precision alignment and press-fit mechanisms, RF signal-path planning, probe selection and shielding design, plus hardware integration and instrument verification on mainstream platforms — complementing your test software and algorithm capabilities.
How is multi-variant production and changeover handled?
Assembly and forming stations use modular layouts, flexible feeding and SMED quick-change fixtures, so routine multi-variant changeover is typically within 15 minutes. Process parameters are stored as per-model recipes and recalled from the HMI, suiting high-mix, low-to-medium-volume production; capacity can be expanded by adding modules without rebuilding the line.
Do you provide turnkey lines or only standalone machines?
Both. Delivery can be a standalone machine, a set of stations, or a full turnkey line. Standard thermal-cleaning solutions follow a standardized process platform configurable per workpiece and takt, while assembly lines and board-test fixtures are designed from single stations to full lines. The delivery model is agreed with you during solution design.
Which industries and customers do you serve?
We serve automotive thermal-management makers and AI liquid-cooling integrators for flow-channel cleaning; automotive component, sensor and electrical-parts makers for intelligent assembly; and AI server and GPU module makers for compute-board test fixtures. Equipment is custom designed and built to each customer's product and process, with clients shown as industry-generic descriptions under confidentiality constraints.
