ʻO ka lipine wela kiʻekiʻe o PTFE he mea koʻikoʻi i ka hana semiconductor, ʻaʻole ia he mea hoʻohana maʻamau. Nā noi koʻikoʻi: ka pale wafer-level (plasma etching masking, CMP backside protection, CVD/PVD masking), nā kaʻina hana hoʻopili (hoʻopaʻa paʻa uea, pale pale pale no nā PCB), a me ka mālama pono (anti-static roller wrapping, cleanroom marking). ʻO nā koi maʻemaʻe loa: nā halogens haʻahaʻa (pale i ka corrosion pad pad), nā siloxanes haʻahaʻa (<500 ppm, pale i ka hoʻokumu ʻana o ka ʻāpana insulating), nā ion metala haʻahaʻa (<1 ppm i kēlā me kēia), ISO Class 4 cleanroom slitting/packaging, 10⁶-10⁹ Ω surface resistivity, a haʻahaʻa TVOC emissions.

ʻO ka hoʻomaʻemaʻe waiwai kumu ke kumu kumu o ka maikaʻi o ka lole kiʻekiʻe o ka PTFE. ʻO nā mea haumia (nā mea hoʻomaka, surfactants, nā ion metala, nā mea hoʻomāinoino ʻia) ke kumu o ka hoʻohaʻahaʻa ʻana i ka wela (bubbles, blistering ma luna o 260°C), nā ʻaoʻao lāʻau ʻole (adhesion anchor point), hoʻemi ʻia ka insulation uila (dielectric loss, haʻahaʻa haʻahaʻa voltage), nāwaliwali ka ikaika mechanical (stress concentration, māwae), ʻO nā mea maka maʻemaʻe kiʻekiʻe e hōʻoia i ka FDA-compliant, lōʻihi ke ola, kiʻekiʻe-hana PTFE lole.

Pono ka hoʻopaʻa ʻana o ka lole fiberglass PTFE-coated i ka manawa paʻa ma 370-400°C. Nā kapuahi mau: 30-90s (ka lahilahi) a 3-5+ min (mānoanoa). Nā kapuahi pahu: 5-15 min. ʻO ka hoʻoheheʻe ʻia ʻana ma lalo o ke kumu o ka opaque, nā ʻili ʻōpala e ʻili; ʻO ka nui o ka sintering ke kumu o ka melemele, brittleness, a me ka hoʻokuʻu kinoea fluoride ʻona. Kaʻina hana: hoʻohana i nā mea nānā wela o ka umu ahi, hana i ka nānā maka (semi-transparent, flexible), a hana i nā hoʻokolohua huki lipine. E hōʻoia mau i ka piha-mānoanoa like like.

Hoʻohui ʻia ka lipine wela kiʻekiʻe o ka PTFE lāʻau lapaʻau i ka substrate PTFE biocompatible me ka lāʻau silikoni-cured platinum. Nā hiʻohiʻona koʻikoʻi: ISO 10993 compliant (ʻaʻohe cytotoxicity, sensitization, a i ʻole irritation), kū i ka sterilization pinepine (ka mahu/EO/gamma), 260°C pale wela. ʻAʻole i ʻoi aku ma mua o 260°C (nā uahi ʻawaʻawa ma luna o 300°C), hiki i ka irradiation gamma ke hana i ka embrittlement, hōʻoia i nā ʻano sterilization, a noi i nā palapala hoʻokō piha (nā hōʻike ISO 10993, MSDS, ʻikepili aging). ʻAʻole no ka hoʻohana ʻana i ke koko pololei a i ʻole implantation ke ʻole i hōʻoia ʻia.

Pono ka lole wela PTFE e mālama pono i ka palekana a me ka lōʻihi. ʻO nā mea nui: ʻaʻole ma mua o 260°C (ma luna o 320°C e hoʻokuʻu i nā ʻawaʻawa ʻawaʻawa), e pale i nā peʻe ʻoi (ka uhi ʻia nā māwae, e hōʻike ana i ka fiberglass), ʻaʻohe hoʻomaʻemaʻe abrasive (hoʻopōʻino ka huluhulu kila i ka ʻili lāʻau ʻole), mālama i ka hoʻonui ʻana i ka wela (pale i ka haehae ʻana), a hoʻololi i ka wā i pohu a ihi ʻia. E kūʻai i ʻōwili ʻia, mamao mai UV. E hoʻohana i nā mīkina lima pale wela i ka wā e lawelawe ai.

ʻO ka PTFE kiʻekiʻe-mehana lole he coefficient o ka hoʻonui wela (CTE) o 30-60 ppm / ° C (warp / weft) - ʻoi aku ka kiʻekiʻe ma mua o ka fiberglass wale nō akā haʻahaʻa loa ma mua o ka PTFE maʻemaʻe (100-200 ppm / ° C). Loaʻa ka PTFE i nā hoʻololi o ka leo (1-2%) ma 19°C a me 30°C. No ka pale ʻana i ka hoʻopaʻa ʻana, ka uhae ʻana, a me ka delamination: hoʻolālā i nā ʻae no ka hoʻonui manuahi, pale i ka hoʻopaʻapaʻa ʻana ma o ka hoʻololi ʻana o ka pae, hoʻohana i nā tensioners ʻakomi ma nā kāʻei conveyor, a kau i ka hoʻolālā overlap anti-buckling. Pono ka nānā mau ʻana no ke kahe anu.

ʻO ka hoʻohana hou ʻana o ka tape PTFE e pili ana i ʻehā mau kumu: ka hoʻopili ʻana (kiʻekiʻe crosslink density, haʻahaʻa silicone migration, microphase structure for repositionable tack), substrate anchoring (surface activation + primer no ka pale ʻana i ka hoʻololi piha ʻana), backside coating (hoʻokuʻu i ka papa no ka pale ʻana i ka mea hoʻopili i ka wā unwinding) Hiki i nā mea hoʻopili i hoʻololi ʻia i ka wai hiki ke hoʻihoʻi hou i ka 90% tack ma hope o ka hoʻomaʻemaʻe.

ʻO ka PTFE kiʻekiʻe-mehana lole moena bakena hāʻawi i ʻehā mau pōmaikaʻi: hana ʻole (ʻaʻohe aila a palaoa paha, hoʻokuʻu maʻemaʻe nā pastries palupalu), ākea ākea ākea (-70 ° C a 260 ° C, palekana no ka umu i ka paʻukū), hiki ke hoʻohana hou ʻia (nā kaukani o nā pōʻai, maʻalahi e hoʻomaʻemaʻe), a hiki i ka hoʻokele wela (pale i ke ahi, kaulike browning). ʻOi aku ka maikaʻi o nā moena silicone me ka hoʻololi wela a ʻoi aku ka maikaʻi o ka ʻili.

He mea nui ka PTFE kiʻekiʻe-mehana lole i ka ʻoihana interlining lole. Nā mea nui: nā kāʻei conveyor pau ʻole ʻole no nā mīkini fusing mau (pale i ka hoʻoheheʻe ʻana i ka hoʻoheheʻe wela, ka lawe ʻole ʻana i ka wrinkle), ka uhi paʻa ʻole a me ka lole pale no nā paʻi wela paʻa (pale i nā papa mai ka hoʻopili ʻia ʻana), nā kāʻei conveyor no nā laina hoʻopaʻa dot/powder coating (mālama paʻa paʻa ʻana i nā kiko i ka wā o ka hoʻopili ʻana), a maloʻo. ʻO ka mānoanoa mai ka 0.13mm (padding māmā) a i ka 0.55mm (nā kāʻei conveyor kaumaha).

Fiberglass lole thermal shrinkage ke kumu nui o ka PTFE tape dimensional instability. Ma PTFE sintering wela (360-400°C), koena ulana koʻikoʻi hoʻokuʻu. Inā ʻaʻole i kāohi ʻia, emi ka lole; inā kāohi ʻia, hoʻopaʻa ʻia ke koʻikoʻi huna, e hoʻemi ʻia ma hope i ka wā o ka hoʻōla ʻana (150-200°C) a me ka hoʻohana ʻana i ka wela. Pane: hoʻohana i ka fiberglass pre-heat-set me <0.5% shrinkage ma 400°C, e hoʻopau i ke koena koʻikoʻi ma mua o ka uhi ʻana.
