Frequently Asked Questions
Why do sheet protectors in an EPA need to be ESD-safe?
Standard plastic sheet protectors are typically made from PVC or polypropylene, which are highly insulative materials that can generate and hold significant electrostatic charges through triboelectric charging (friction from handling). In an ESD-protected area, these charges can discharge to nearby ESD-sensitive components, causing latent or catastrophic damage. ESD-safe sheet protectors like the Desco 07473 are made from materials that dissipate static charge safely, preventing charge buildup at the workstation.
What does amine-free mean and why does it matter?
Amines are chemical compounds found in some plastics and coatings that can outgas and contaminate sensitive surfaces — particularly conformal coatings, adhesives, and optical coatings that are sensitive to amine contamination. In electronics assembly environments where conformal coating or adhesive bonding is performed, amine contamination from sheet protectors or other materials at the workstation can cause coating adhesion failures or cure inhibition. The Desco 07473 is amine-free, making it safe for use in these sensitive environments.
Can the Desco 07473 be used in lead-free soldering environments?
Yes — the 07473 is specifically noted as appropriate for use in lead-free work areas and is RoHS compliant. It will not introduce lead or other restricted substances to the work area.
What is a shop traveler and why is an ESD-safe protector needed?
A shop traveler is a document that accompanies a PCB or assembly through the production process, recording work instructions, inspection results, serial numbers, and process steps at each workstation. Shop travelers are handled frequently at ESD-sensitive workstations, so the sheet protector holding them must be ESD-safe to avoid introducing static charge sources near sensitive components during handling.
