Nsuo a Ɛtɔ Angle Tester Dwumadie Titiriw

1. Surface Wettability Nhwehwɛmu

Nsuo a ɛtɔ gu fam tester susuw sɛnea nsu (mpɛn pii no nsu) a ɛwɔ ade a ɛyɛ den so no di nkitaho, na ɛkyerɛ sɛnea ade no tumi yɛ nwini tẽẽ. Contact angle a ennu digrii 90 kyerɛ sɛ ade bi yɛ hydrophilicity (sɛ nhwɛso no, nsu a ɛtɔ gu ahwehwɛ so); contact angle a ɛboro 90℃kyerɛ hydrophobicity (sɛ nhwɛso no, lotus effect). Saa data yi yɛ ade titiriw a ɛkyerɛ sɛnea ade bi ani so ahoɔden, ahotew, anaa nsakrae a etu mpɔn no hwɛ. Sɛ nhwɛso no, wɔ semiconductor adwumayɛ mu no, ɛsɛ sɛ wɔhwɛ contact angle a ɛwɔ wafer soro no so wɔ digrii 5 ne digrii 10 ntam (a ɛkyerɛ ISO 19403-2) na ama photoresist no abata ho pɛpɛɛpɛ.

2. Coating Adwumayɛ ho Nhwehwɛmu

Wɔ nneɛma a wɔde kata so a ɛyɛ adwuma (te sɛ nsu-repellent, anti-fouling, ne anti-reflective coatings) a wɔyɛ mu no, wɔde nsuo a ɛtɔ fam angle tester di dwuma de kyerɛ sɛnea akatasoɔ no yɛ adwuma yie. Sɛ nhwɛso no, ɛsɛ sɛ hydrophobic coating a ɛwɔ kar ahwehwɛ so no nya contact angle a anyɛ yiye koraa no 110℃(sɛnea SAE J1960 kyerɛ no) na ama wɔahwɛ ahu sɛ osutɔ nsu no bɛbɔ ntɛmntɛm-.
