DESCRIPTION
DuPont™ Pyralux® HT flexible circuit material is a complete
all-polyimide flex laminate system that includes a double-sided, copper-clad laminate and a unique all-polyimide coverfilm or bonding material that becomes a flexible coverlay after processing. The bonding material can be ud as a coverfilm, offering good coverage over circuits, or as a bonding material for multilayer flex applications. This material system is ideal for multilayer flex and rigid flex applications which require high operating temperature performance, advanced material performance, and high reliability.

GENERAL INFORMATION
Quality and Traceability
末代皇帝观后感
DuPont™ Pyralux® HT flexible circuit material copper clads are manufactured under a quality system registered to ISO9002 by Underwriters Laboratories. The copper clad laminates are certified to IPC-4204/11. The bonding/cover film is certified to IPC-4203/24. Complete material and manufacturing records, which include archive samples of finished product, are maintained by DuPont. Each manufactured lot is identified for reference and traceability. The packaging label rves as the primary tracking mechanism in the event of customer inquiry and includes the product name, batch number, size, and quantity.
Storage Conditions and Warranty
DuPont™ Pyralux® HT flexible circuit material laminates should be stored in the original packaging at temperatures of 4-29°C (40-85°F) and below 70% humidity. The product should not be frozen and should be kept dry, clean and well protected. Subject to compliance with the foregoing handling and storage recommendations, the DuPont warranty, as provided in the DuPont Standard Conditions of Sale, shall remain in effect for a period of two years following the date of shipment.Safe Handling
Anyone handling DuPont™ Pyralux® HT flexible circuit materials should wash their hands with soap before eating, smoking, or using restroom facilities. Although DuPont is not aware of anyone develop
ing contact dermatitis when using DuPont™ Pyralux® HT products, some individuals may be more nsitive than others. Gloves, finger cots, and finger pads should be changed daily. DuPont™ Pyralux® HT flexible circuit materials are fully cured when delivered. However, lamination areas should be well ventilated with a fresh air supply to avoid build-up from trace quantities of residual solvent (typical of polyimides) that may volatilize during press lamination. When drilling or routing parts made with DuPont™ Pyralux® HT, provide adequate vacuum around the drill to minimize worker exposure to generated dust. As with all thin, copper-clad laminates, sharp edges prent a potential hazard during handling. All personnel involved in handling Pyralux® HT clads should u suitable gloves to minimize potential cuts.
