5.3 The product quality should be different within 30 days after receipt according to the acceptance test report. The maximum delivery age of the manufacturer, 6 marking, packaging, transportation and storage
Marking, packaging, transportation and storage should comply with the provisions of B2 of the safety association. Each substrate is wrapped with capacitor paper and packed with polyolefin film. The package contains a strict product quality certificate, indicating: product name, specification, dielectric tape number, individual quality exemption from cutting. Make it good, inspection results and production date, and put the substrate of the sealed part into a smaller size (do not exceed the size of the block) to ensure the quality of the film.
It can be transported by pressing into pellets. During transportation, the base should be packed in a technical box to prevent damage from heat and other mechanical damage.
