I ka hana semiconductor, ana ʻia ka contamination ma nā ʻāpana o ka miliona a me ka nui o nā ʻāpana i nā microns. Hiki i kahi ion hele wale, kahi pūhui mea hoʻoheheʻe maʻemaʻe, a i ʻole kahi ʻāpana microscopic hiki ke ʻoki i kahi pūʻulu wafer holoʻokoʻa - ke kumu kūʻai ʻia he mau haneli kaukani kālā.
PTFE kiʻekiʻe-mehana lipine , me kona wela wela, kemika inertness, non-stick ili, a me ka uila waiwai, pāʻani koʻikoʻi i loko o kēia kaiapuni. Akā ʻaʻole e hana ʻia kahi tape PTFE. Pono nā lipine semiconductor-grade e hoʻokō i nā kūlana hoʻomaʻemaʻe kiʻekiʻe loa ma mua o nā lipine ʻoihana maʻamau.
Hana ʻo Aokai PTFE i ka lipine PTFE no nā noi semiconductor. Hoʻopili kēia alakaʻi i ʻekolu mau wahi noi nui - ka hana ʻana i ka wafer-level, ka hoʻopaʻa ʻana a me ka hoʻāʻo ʻana, a me ka mālama ʻana i nā mea hana - a me nā koi hoʻomaʻemaʻe ikaika e pili ana i kēlā me kēia.
Nā Manaʻo Hoʻohana Koʻikoʻi - Pale ʻana i nā ʻāpana Waiwai Kiʻekiʻe
1. Pale kaʻina hana wafer-level
I ka wā o ka hana ʻana i ka wafer, hoʻohana ʻia ka lipine ma ke ʻano he pale pale no nā mea waiwai kiʻekiʻe.

ʻO ka hoʻomaʻemaʻe a me ka hoʻomaʻemaʻe plasma
E uhi i nā wahi hana ʻole, e pale i nā ʻaoʻao wafer mai ka hoʻopā ion
ʻAʻole pono e haʻalele a waiho i ke koena; kū i ka honua plasma

2. Hoʻopili a me nā kaʻina hana hoʻāʻo
Ka hoʻopaʻa ʻana o ke kumu alakaʻi / substrate: Ke hoʻonohonoho ʻana i ka wela i ka wā e hoʻopaʻa ʻia ai ka uea, hoʻopili make, a me ka hoʻopaʻa ʻana i ka plastic - paʻa nā ʻāpana i nā wela kiʻekiʻe.
ʻO ka pale ʻana no ka hoʻoheheʻe ʻana i ka nalu a me ka hoʻoheheʻe hou ʻana: Pale i nā manamana gula a me nā wahi hoʻopili ma nā PCB mai ka hoʻohaumia ʻana o ka solder i nā kaʻina hana kūʻai wela kiʻekiʻe.
Nā pepa lawe lipine kiʻekiʻe: ʻO nā mea lawe maʻalahi e hoʻopaʻa i nā substrate liʻiliʻi ma nā laina hana me ka hoʻokuʻu ʻole ʻana i nā ʻāpana a i ʻole ke koena.
3. Ka mālama ʻana i nā lako a me nā hoʻohana kōkua
ʻAi-static roller wrapping: Clads transport rollers e hāʻawi i ka wela kiʻekiʻe, non-stick, a me static-dissipative contact surfaces - pale i ka pōʻino wafer mai ka friction a me ka hoʻokuʻu static.
Mākaʻikaʻi a me ka mālama ʻana i ka lumi maʻemaʻe: No ka hoʻopaʻa inoa ʻana, ka hoʻoponopono ʻana i ke kelepona no ka manawa pōkole, a me ka hoʻoponopono liʻiliʻi me ka hoʻokomo ʻole ʻana i nā mea haumia.
ʻO kēia nā maʻamau e hoʻokaʻawale i ka tape PTFE semiconductor-grade mai ka lipine maʻamau. ʻO ka hoʻokō ʻole hiki ke alakaʻi i ka pau ʻana o ka pūʻulu piha. Hoʻopaʻa ʻo Aokai PTFE i kēia mau ʻāpana āpau no kā mākou mau lipine semiconductor-grade.
