Integrated surface morphology and contaminant detection solution

Section 1: In-depth Analysis of 3D Surface Topography Module

1. 3D Reconstruction Technology

• Achieve holographic imaging with surface roughness down to 0.1μm (Sa/Sz), simultaneously correlating contact angles with micro-morphological parameters (such as porosity, peak-to-valley ratio).

• Wettability - Structural Model: Construct a three-dimensional wetting distribution map using contact angle meter data, quantifying the guiding effect of microgrooves (width > 2μm) on droplet spreading.

• Functional Coating: Assess uniformity of superhydrophobic surface micropillar arrays (qualified with contact angle fluctuation <1° or surface tension deviation >2 mN/m)

• Electronic Packaging: Wafer Cutting Path Contaminant 3D Location (ASTM D5946 Standard Report Automatically Generated)

Module of innovative application in surface tension by mechanical method

1. Platinum Plate Pollution Detection System

• Real-time monitoring of solid-liquid interface tension decay curve (sampling rate 10Hz), identifying organic pollutant adsorption (Δγ > 2mN/m triggers alarm)

• Combined with the contact angle measurement instrument, Acid-baSE model, analyzes the percentage of polar component of pollutants (threshold setting: γ^P > 25% is deemed as organic residue)

• Equipment: Biofilm Contamination Assessment (Compliant with ISO Biocompatibility Standards)

• Food Packaging: Oil Migration Pollution Detection (Alert for Contact Angle Hysteresis Δθ > 8°)
