Menene TTV, BOW, WARP, da TIR suke nufi a cikin Wafers?

A lokacin da ake yin nazari kan wafers na siliki ko abubuwan da aka yi da wasu kayan, sau da yawa muna haɗuwa da alamun fasaha kamar: TTV, BOW, WARP, da yuwuwar TIR, STIR, LTV, da sauransu. Wadanne sigogi ne waɗannan ke wakilta?

TTV - Jimlar Bambancin Kauri
BOW - Baka
WARP - Warp
TIR - Jimlar Karatun da aka Nuna
STIR - Gabaɗayan Rubutun da aka Nuna Karatu
LTV - Bambancin Kauri na Gida

1. Jimlar Bambancin Kauri - TTV

Bambanci tsakanin matsakaicin matsakaici da mafi ƙarancin kauri na wafer dangane da jirgin sama lokacin da aka matse wafer kuma a cikin kusanci. Gabaɗaya ana bayyana shi a cikin micrometers (μm), galibi ana wakilta kamar: ≤15 μm.

2. Baka - BOW

Bambance-bambance tsakanin mafi ƙanƙanta da matsakaicin nisa daga tsakiyar wurin wafer saman zuwa jirgin sama lokacin da wafer ke cikin yanayin kyauta (wanda ba a haɗa shi ba). Wannan ya haɗa da nau'i-nau'i biyu na concave (mara kyau baka) da kuma convex (tabbatacciyar baka). Yawanci ana bayyana shi a cikin micrometers (μm), galibi ana wakilta kamar: ≤40 μm.

3. Warp - WARP

Bambance-bambancen tsakanin mafi ƙanƙanta da matsakaicin nisa daga saman wafer zuwa jirgin sama mai tunani (yawanci saman baya na wafer) lokacin da wafer yake cikin yanayin kyauta (wanda ba a haɗa shi ba). Wannan ya haɗa da duka concave (mara kyau warp) da convex (tabbataccen warp). Gabaɗaya ana bayyana shi a cikin micrometers (μm), galibi ana wakilta kamar: ≤30 μm.

4. Jimlar Karatun da aka Nuna - TIR

Lokacin da wafer ɗin ya matse kuma yana cikin kusanci, ta amfani da jirgin sama mai nuni wanda ke rage adadin abubuwan da aka samu na duk maki a cikin yanki mai inganci ko ƙayyadaddun yanki na yanki akan saman wafer, TIR shine karkata tsakanin matsakaicin matsakaici da mafi ƙarancin nisa daga saman wafer zuwa wannan jirgin sama.
