How to Safe Handling for PYRALUX AP8525R PCB Materials?

It is important for individuals handling DuPont™ Pyralux® AP flexible circuit materials to wash their hands with soap before engaging in activities such as eating, smoking, or using restroom facilities. While DuPont is not aware of any cases of contact dermatitis associated with the use of DuPont™ Pyralux® AP products, it is possible that some individuals may have a higher sensitivity than others. Therefore, it is recommended to use gloves, finger cots, and finger pads, and these protective measures should be changed on a daily basis.

DuPont™ Pyralux® AP flexible circuit materials are fully cured upon delivery. However, it is advisable to ensure proper ventilation in lamination areas, with a fresh air supply, to prevent the accumulation of trace amounts of residual solvent (common in polyimides) that may volatilize during press lamination. When drilling or routing parts made with DuPont™ Pyralux® AP, it is important to provide adequate vacuum around the drill to minimize worker exposure to generated dust.

As is the case with all thin, copper-clad laminates, sharp edges can pose a potential hazard during handling. Therefore, all personnel involved in handling Pyralux® AP clads should use suitable gloves to minimize the risk of cuts.

Storage Conditions and Warranty

Dupont PYRALUX AP8525R flexible circuit material laminates should be stored within their original packaging at temperatures ranging from 4-29°C (40-85°F) and humidity levels below 70%. It is crucial to prevent the product from freezing and to maintain a dry, clean, and well-protected environment. Adherence to these recommended handling and storage guidelines is essential to ensure the validity of the DuPont warranty, as stated in the DuPont Standard Conditions of Sale, which covers a period of two years from the shipment date.

Quality and Traceability

The copper clads of Dupont PYRALUX AP8525R flexible circuit material are produced within a quality system that is registered to ISO9002 by Underwriters Laboratories. These clads are certified to meet the IPC-4204/11 standard. DuPont meticulously maintains comprehensive material and manufacturing records, which encompass archived samples of the finished product. Each manufacturing lot is assigned a unique identification for easy reference and traceability. The packaging label plays a critical role as the primary tracking mechanism in the event of customer inquiries, containing essential information such as the product name, batch number, size, and quantity.
