Hoʻohana ʻia nā hemahema o Granite i nā huahana hana wafer

ʻO Granite kahi pōhaku kūlohelohe i hoʻohana ʻia no ka manawa lōʻihi i nā mea hana wafer.Ua ʻike ʻia no kāna mau waiwai maikaʻi loa o ka hoʻonui haʻahaʻa wela, ka rigidity kiʻekiʻe a me ke kūpaʻa maikaʻi.Eia nō naʻe, e like me nā mea āpau, loaʻa i ka granite kāna mau hemahema ponoʻī e hiki ke hoʻopilikia i ka maikaʻi o nā mea hana wafer.

ʻO kekahi o nā hemahema nui o ka granite, ʻo ia ka maʻa a haki paha.ʻO kēia ma muli o ka loaʻa ʻana o nā microcracks hiki ke hana i ka wā o ka hoʻokumu ʻana o ka pōhaku.Inā ʻaʻole ʻike ʻia kēia mau microcracks a mālama pono ʻia, hiki iā lākou ke hoʻolaha a alakaʻi i ka hemahema o nā mea hana.No ka pale ʻana i kēia, pono nā mea hana hana e hoʻohana i ka granite kiʻekiʻe i mālama ʻia a hoʻāʻo ʻia e hōʻoia i ka ʻole o nā microcracks.

ʻO kekahi hemahema o ka granite, ʻo ia ka maʻalahi o ka ʻino.Inā pili nā mea hana granite me nā kaiapuni corrosive, hiki ke hoʻomaka e hoʻohaʻahaʻa i ka manawa.Hiki i kēia ke alakaʻi i ka pohō a i ʻole ka hana pono ʻana o nā mea hana.No ka pale ʻana i kēia, pono nā mea hana e hōʻoia i ka mālama pono ʻana o ka granite i hoʻohana ʻia i kā lākou mau mea hana a hoʻopaʻa ʻia i mea e pale aku ai i ka corrosion.

He mea maʻalahi hoʻi ka Granite i ka warping i ka manawa ma muli o kona mau waiwai wela.ʻO kēia no ka mea he haʻahaʻa loa ka coefficient o ka hoʻonui wela o ka granite, ʻo ia hoʻi, ʻaʻole ia e hoʻonui a ʻaelike paha i ka wā e hoʻololi ʻia ai ka mahana.Eia nō naʻe, hiki i kahi liʻiliʻi o ka hoʻonui ʻana a i ʻole ka hoʻopaʻa ʻana ke kumu i ka warping i nā mea hana i ka manawa.He mea nui ka noonoo ana o ka mea hana mea hana i na waiwai wela o ka granite i ka wa e kukulu ana i ko lakou mau mea hana e pale aku ai i keia hemahema.

ʻO ka hope, hiki i ke ʻano porous o ka granite ke alakaʻi i nā pilikia me ka haumia.Inā ʻaʻole i hoʻopaʻa pono ʻia ka granite, hiki iā ia ke komo i nā mea haumia e hiki ke hoʻopilikia i ka maikaʻi o ka wafer.Hiki i kēia ke alakaʻi i ka manawa haʻahaʻa a me ka nalowale o ka hana.No ka pale ʻana i kēia, pono nā mea hana e hoʻopaʻa pono i ka granite e pale i nā mea haumia mai ka komo ʻana.

I ka hopena, he mea maikaʻi loa ka granite no ka hoʻohana ʻana i nā lako hana wafer.Eia naʻe, he mea nui e makaʻala i kona mau hemahema a lawe i nā mea e pono ai e pale aku i ka hiki ʻana mai.Me ka mālama pono a me ka mālama pono, hiki ke hoʻomau i nā mea hana granite no nā makahiki he nui, e hāʻawi ana i nā wafers kiʻekiʻe no ka ʻoihana semiconductor.
