Adhesive Overflow Control
Definition
Preventing adhesive from migrating beyond tape edges.
Historical Background
1980s: edge sealing and silicone treatment solved severe bleed problems.
Example
Adhesive seeping from edges dirties surfaces. Like staying within the lines.
Formula
Adhesive Bleed Amount (g/m) = Overflow Mass / Tape Length
Core Concepts
Root cause of production incidents: contaminating equipment and products.
Extended Applications
Ordinary: <5 g/m; precision: <1; electronic: <0.5; optical: <0.1; aerospace: <0.05 g/m.
