Pūwhakaputa Ukume Panipani Teflon – Mata Kore-Pīpiri mō te Whakahaere Wafer Tairongo
Ko te taputapu pito uku kua pania ki te Teflon (PTFE) a St.Cera e whakakotahi ana i tētahi papa alumina kaha-teitei me tētahi paninga PTFE ōrite, iti-waku (matotoru 15–30 μm). Ka whakaratohia e te paninga he tauwehenga waku tino iti (≤0.1), he ātete matū pai rawa atu, me ngā āhuatanga kore-piri, e ārai ana i te piri o te papa whakarewa me te whakakore i te poke o te taha o muri. Ko te papa uku kei raro (99.8% Al₂O₃) e tuku ana i te kaha piko teitei (361–1000 MPa), te ātete kakahu, me te pumau wera tae atu ki te 260°C (te rohe paninga). He pai tēnei taputapu pito mō te whakahaere i ngā papa whakarewa ngawari, angiangi, piri rānei (hei tauira, i muri i te paninga photoresist, i ngā tukanga matū rānei).
Ngā Whakatakotoranga (i runga i te papa 99.8% Al₂O₃ me te paninga PTFE):
| Taonga | Uara |
| Rauemi Papa | 99.8% Arumina (Ai) |
| Rauemi Paninga | PTFE (Teflon) |
| Matotoru o te paninga | 15–30 μm |
| Tauwehenga o te Waku (Kua Pania) | ≤0.1 |
| Kaha Piko o te Papa (Al₂O₃) | 361 MPa |
| Te Mārō o te Papa (Al₂O₃) | 16 GPa |
| Te Kīanga o te Papa | 3.93 karamu/cm³ |
| Te pāmahana whakahaere mōrahi (te rohenga paninga) | 260°C |
| Te Pākari o te Mata (i mua i te paninga) | Ra ≤0.4 μm |
| Kaha Whakakore Hiko (papa) | 15×10⁶ V/m |
Kia mōhio: Ka whakawhāitihia e te paninga PTFE te pāmahana mōrahi ki te 260°C; mō ngā whakamahinga pāmahana teitei ake, whakaarohia te uku kāore i pania, me ētahi atu paninga rānei.
Ngā tono:
- · Te whakahaere i ngā papa i muri i te paninga photoresist (ngā mata piri)
- · Te whakawhiti i ngā angiangi, pakarukaru rānei (ārai i te piri)
- · Ngā taputapu tirotiro me te ine ira mō ngā haurua-ārahi
- · Te aunoatanga o te rūma horoi, me whakaiti te poke o ngā matūriki
Tukanga Hanga:
Te papa uku kua whakatōngia, kua hurihia kia tika → te whakakorikori i te mata (te werohanga plasma, te pupuhi kirikiri rānei) → te paninga rehu PTFE → te whakamaroke wera i te 380°C → te tirotiro whakamutunga. Ka tirohia ia pito pānga mō te matotoru o te paninga (te au hurihuri), te piri (te whakamātautau tapahi whakawhiti ASTM D3359), me te tauwehenga waku.
Mana Kounga:
Tirotiro ā-kanohi 100% mō ngā kōhao iti, ngā mirumiru rānei; te matotoru o te paninga kia ōrite i roto i te ±5 μm; kāore he wehewehenga i muri i te whakamātautau piko 90° i runga i te tīkitipati kaiwhakaatu. Tirohia ngā āhuatanga ki te manawanui OEM (roa ±0.05 mm, papatahi ≤0.1 mm).
Ngā Painga ki ngā Paninga Kore-Panitia, ki ētahi atu Paninga rānei:
- · Ka ārai te mata korepiri i te piri me te pakaru o te papa
- · Te tauwehenga waku iti rawa i waenga i ngā paninga uku
- · He ātete matū tino pai (waikawa, kawakore, whakarewa)
- · Ka whakaiti i te whakaputanga matūriki mā te aukati i te whakawhiti rauemi
Ngā Here (ngā kōrero mō te rerekētanga rauemi):
Kāore te paninga PTFE i ahu mai i ngā ripanga āhuatanga rauemi kua whakaratohia (Al₂O₃, ZrO₂, Si₃N₄, BeO). E whai pū ana ngā āhuatanga o te papa i te pepa raraunga kua whakaratohia (99.8% Al₂O₃). E hangai ana ngā āhuatanga paninga ki ngā whakaritenga PTFE paerewa ā-umanga, nā te mea kāore he raraunga paninga i whakaratohia. Mō ngā tono neke atu i te 260°C, e taunakihia ana he pito uku kore paninga.*
Whakaritenga:
Kei te wātea mai i te roa 150–1500 mm, ngā āhua o te pito (te pupuri taha, Bernoulli, papatahi), ngā tauira whakapiringa e ai ki te tuhi OEM. He kōwhiringa te paninga wāhanga (ngā wāhi pa anake) te hipoki katoa rānei.
Tonoa he tauira mō te whakamātautau piri me te waku.
