Bonding Surface Treatment
Definition
Surface processing of substrates to improve bonding performance.
Historical Background
1960s: surface treatment increased bonding strength 3-5x.
Example
Clean oily metal with alcohol before taping for much better adhesion. Like laying a foundation.
Formula
Bonding Strength = Base Strength x Treatment Coefficient
Core Concepts
Increasing interfacial forces via cleaning, roughening, or chemical modification.
Extended Applications
Cleaning: general; plasma: electronic (increase surface energy); primer: metal; corona: film; flame: plastic.
