The required inspection items should be defined according to the customer's product specifications and quality control requirements.

4. Quality, Reliability and Factory Requirements

Q11: What quality and reliability performance can customers expect?

Quality and reliability targets depend on the production line model, equipment configuration, manufacturing process, and acceptance criteria.

Certain configurations in our product documentation specify product qualification rates of at least 99.8%, final yield rates of at least 99.9%, and an overall line failure rate of no more than 3%.

A separate premium production line specification lists an OEE target of at least 88%, a first-pass yield of at least 99.3%, and a second-pass yield of at least 99.67%, subject to the stated calculation conditions.

These figures apply to the relevant configurations and should not be treated as universal guarantees for every production line. Final performance indicators and acceptance methods must be agreed upon for each project.

Q12: What factory space and utilities are required?

Factory requirements vary according to the production line layout, equipment configuration, product dimensions, and auxiliary systems.

For reference, a premium production line specification lists AC 220 V/50 Hz and AC 380 V/50 Hz power supplies, a rated power of 115 kW, and an air pressure range of 0.4–0.7 MPa.

These figures are specific to the referenced configuration. The actual factory space, utility capacity, equipment arrangement, and installation conditions should be confirmed during project evaluation.
