Tesa Precision Mask, 38mm Width, 85μm Thickness - 04342-00003-00


This precision mask is a paper-backed copper tape designed for controlled masking in thermal and Electronic Assembly contexts. It combines a metallic backing with an acrylic adhesive to provide a defined protective layer during processes that involve elevated temperatures and fine-detail masking.

Features and Benefits:


• Acrylic adhesive provides a strong bond for secure masking
• Copper backing enables electrical conductivity where needed
• Withstands temperatures up to 150°C for heat processes
• Adhesion measured at 1.5N/cm supports stable placement
• Tensile strength of 32N/cm resists tearing during handling
• Available in a thin 85μm construction for precise contours

Applications


• Suitable for PCB soldering where selective masking is required
• Ideal for electronics masking during reflow and wave soldering
• Used with fine-edge masking tasks in thermal processing
• Can be used for temporary earthing or shielding during assembly
• Suitable for machine application in roll-fed production lines

What is the tape’s backing material and its implication?


The backing is paper which allows controlled conformability and easy handling during application and removal.

How long is a single roll and how does that affect workflows?


Each roll is 50 m long, providing extended run lengths to reduce the frequency of reel changes in production.

What width options are available and how does width impact precision?


The supplied width is 38 mm, which balances handiness and coverage for narrow masking tasks.

How thick is the material and why does thickness matter?


The overall thickness is 85 μm, which helps achieve precise edge definition while remaining flexible for fine features.
