Waxyeelaha Dhammaadka Dhoobada ee Teflon-ka lagu dahaadhay - Dusha sare ee aan dheg lahayn ee loogu talagalay maaraynta Wafer-ka Xasaasiga ah
Qalabka wax soo saarka dhoobada ee St.Cera's Teflon (PTFE) ee dahaaran wuxuu isku daraa substrate alumina oo xoog badan leh oo leh dahaar PTFE oo isku mid ah oo is jiidjiid hooseeya (dhumucdiisuna waa 15-30 μm). Dahaarka wuxuu bixiyaa isku-xidhnaan aad u hooseeya (≤0.1), iska caabin kiimiko oo aad u fiican, iyo sifooyin aan dhegdheg lahayn, isagoo ka hortagaya isku-xidhka waferka iyo baabi'inta wasakhda dhabarka. Substrate-ka dhoobada ee hoose (99.8% Al₂O₃) wuxuu bixiyaa xoog dabacsan oo sare (361–1000 MPa), iska caabin xirasho, iyo xasillooni kuleyl ilaa 260°C (xadka dahaarka). Qalabkan wax soo saarka dhammaadka ah wuxuu ku habboon yahay maaraynta wafers jilicsan, khafiif ah, ama dhegdheg leh (tusaale ahaan, ka dib dahaarka sawir-qaadista ama hababka kiimikada).
Tilmaamaha (oo ku salaysan 99.8% Al₂O₃ substrate oo leh dahaarka PTFE):
| Hantida | Qiimaha |
| Qalabka Substrate-ka | 99.8% Alumina (Ceyri) |
| Qalabka dahaadhka | PTFE (Teflon) |
| Dhumucda dahaarka | 15–30 μm |
| Isku-dhafka Khilaafka (Dahaaran) | ≤0.1 |
| Xoogga Laab-la'aanta Substrate-ka (Al₂O₃) | 361 MPa |
| Adkaanshaha Substrate-ka (Al₂O₃) | 16 GPA |
| Cufnaanta Substrate-ka | 3.93 g/cm³ |
| Heerkulka ugu Sareeya ee Hawlgalka (xadka dahaarka) | 260°C |
| Qalafsanaanta Dusha sare (kahor inta aan la dahaadhin) | Ra ≤0.4 μm |
| Xoogga Dielectric (substrate) | 15 × 10⁶ V/m |
Fiiro gaar ah: Dahaarka PTFE wuxuu heerkulka ugu badan ku xaddidaa 260°C; haddii aad u baahato heerkul sare, tixgeli dhoobada aan dahaarka lahayn ama dahaarka kale.
Codsiyada:
- · Maareynta buskudka ka dib dahaarka photoresist (sagxadaha dhegdheg leh)
- · Wareejinta buskudka khafiifka ah ama jilicsan (ka hortagtaa dhegdheg)
- · Qalabka kormeerka semiconductor-ka iyo mitirka
- · Is-waafajinta qolka nadiifka ah halkaas oo wasakhowga walxaha ay tahay in la yareeyo
Habka Wax Soo Saarka:
Dhul-hoosaadka dhoobada ah ee sifaysan iyo saxnaanta dhulka → xoqidda dusha sare (plasma etch ama grit blast) → Dahaarka buufinta PTFE → kululaynta kulaylka 380°C → kormeerka kama dambaysta ah. Wax-qabad kasta oo dhammaadka ah waxaa loo hubiyaa dhumucda dahaarka (current eddy), dhejinta (tijaabada isgoyska ASTM D3359), iyo isku-dhafka is-jiidjiidka.
Xakamaynta Tayada:
Kormeer muuqaal ah oo 100% ah oo loogu talagalay godadka biinanka ama xumbo; isku-dhafka dhumucda dahaarka gudaha ±5 μm; ma jiro kala-goyn ka dib tijaabada leexashada 90° ee ku-darka markhaatiga. Hubinta cabbirka ee dulqaadka OEM (dhererka ±0.05 mm, fidsanaan ≤0.1 mm).
Faa'iidooyinka Dahaarka aan dahaarka lahayn ama kuwa kale:
- · Dusha sare ee aan dhegdheg lahayn waxay ka hortagtaa dhegdheg iyo jabitaan wafer ah
- · Isku-darka ugu hooseeya ee is-jiidjiidka u dhexeeya dahaarka dhoobada
- · Iska caabin kiimiko oo aad u fiican (asiidh, saldhigyo, dareereyaal)
- · Waxay yareysaa soo saarista walxaha iyadoo ka hortageysa wareejinta walxaha
Xaddidaadaha (faallooyin ku saabsan leexashada agabka):
Dahaarka PTFE kama soo baxo jaantusyada hantida agabka la bixiyay (Al₂O₃, ZrO₂, Si₃N₄, BeO). Sifooyinka substrate-ka si adag ayay u raacaan xaashida xogta la bixiyay (99.8% Al₂O₃). Sifooyinka dahaarka waxay ku salaysan yihiin qeexitaannada heerka warshadaha ee PTFE, maadaama aan la bixin xog dahaar ah. Codsiyada ka badan 260°C, waxaa lagu talinayaa in la isticmaalo wax-qabad dhammaadka dhoobada ah oo aan dahaar lahayn.*
Habayn:
Waxaa laga heli karaa dherer ahaan 150–1500 mm, qaababka caarada (qabashada geeska, Bernoulli, fidsan), qaababka flange-ka ee lagu rakibayo sawirka OEM. Dahaarka qayb ahaan (kaliya meelaha taabashada) ama daboolida buuxda waa ikhtiyaari.
