Nā Papa Pai ʻia ʻo Rigid-Flex: ʻEkolu mau ʻanuʻu no ka hoʻomaʻemaʻe ʻana i loko o nā lua

I nā papa paʻi paʻa paʻa, ma muli o ka hoʻopili maikaʻi ʻana o ka uhi ʻana ma ka paia o ka lua (ka ʻili ʻoniʻoni maʻemaʻe a me ka pepa hoʻopaʻa), maʻalahi ka hoʻokaʻawale ʻana o ka uhi mai ka pā puka ke hoʻokau ʻia i ka haʻalulu wela. , Pono hoʻi i kahi hoʻomaha ma kahi o 20 μm, no laila ʻo ke apo keleawe i loko a me ke keleawe electroplated i loko o kahi pilina ʻekolu mau kikoʻī, e hoʻomaikaʻi maikaʻi loa i ka pale ʻana i ka wela o ka lua metallized. ʻO ka Capel ma lalo nei e kamaʻilio kikoʻī no ʻoe. ʻEkolu mau ʻanuʻu no ka hoʻomaʻemaʻe ʻana i ka lua ma hope o ka ʻeli ʻana i ka papa paʻa.

Ka ʻike no ka hoʻomaʻemaʻe ʻana i loko o ka lua ma hope o ka wili ʻana i nā kaʻa kaʻa kaʻa.

No ka mea, ʻaʻole kūʻē ka polyimide i ka alkali ikaika, ʻaʻole kūpono ka māmā alkaline potassium permanganate desmear no nā papa paʻi maʻalahi a paʻa. ʻO ka maʻamau, pono e hoʻomaʻemaʻe ʻia ka lepo wili ma ka papa palupalu a paʻakikī e ka hoʻomaʻemaʻe plasma, i māhele ʻia i ʻekolu mau ʻanuʻu:

(1) Ma hope o ka loaʻa ʻana o ka lua o nā mea hana i kahi pae o ka vacuum, ua hoʻokomo ʻia ka nitrogen maʻemaʻe kiʻekiʻe a me ka oxygen hoʻomaʻemaʻe kiʻekiʻe i loko, ʻo ka hana nui ka hoʻomaʻemaʻe ʻana i ka paia o ka lua, preheat ka papa i paʻi ʻia, a hana i ka mea polymer. loaʻa i kekahi hana, i mea pōmaikaʻi Ka hana ma hope. ʻO ka maʻamau, ʻo 80 degere Celsius a ʻo ka manawa he 10 mau minuke.

(2) CF4, O2 a me Nz pane me ka resin e like me ke kinoea kumu e hoʻokō i ke kumu o ka decontamination a etch hope, maʻamau ma 85 degere Celsius a no 35 minuke.

(3) Hoʻohana ʻia ʻo O2 ma ke ʻano he kinoea kumu e wehe ai i ke koena a i ʻole "lehu" i hana ʻia ma nā ʻanuʻu mua ʻelua o ka mālama ʻana; hoʻomaʻemaʻe i ka pā puka.

Akā, he mea pono e hoʻomaopopo i ka wā e hoʻohana ʻia ai ka plasma e wehe i ka lepo wili i loko o nā lua o nā papa paʻi paʻi paʻi a me ka paʻa paʻa, ʻokoʻa ka wikiwiki etching o nā mea like ʻole, a ʻo ke kauoha mai ka nui a hiki i ka liʻiliʻi: acrylic film. , epoxy resin , polyimide, fiberglass a me ke keleawe. Hiki ke ʻike maopopo ʻia nā poʻo fiber aniani a me nā apo keleawe ma ka paia puka mai ka microscope.

I mea e hōʻoia ai e hiki ke hoʻopili piha i ka pā o ka puka keleawe electroless, no laila ʻaʻole e hoʻopuka ka papa keleawe i nā lua a me nā lua, ʻo ke koena o ka hopena plasma, ke kīʻaha aniani protruding a me ka kiʻiʻoniʻoni polyimide ma ka paia o ka puka. wehe ʻia. ʻO ke ʻano hana lapaʻau e pili ana i nā ʻano mechanical a me mechanical a i ʻole kahi hui o nā mea ʻelua. ʻO ke ʻano kemika, ʻo ia ka hoʻohu ʻana i ka papa i paʻi ʻia me kahi solution ammonium hydrogen fluoride, a laila hoʻohana i ka ionic surfactant (KOH solution) e hoʻoponopono i ka hoʻopiʻi o ka pā puka.

Hoʻokomo ʻia nā ʻano hana mīkini me ka holoi ʻana i ka wai wai ikaika kiʻekiʻe. ʻO ka hui pū ʻana o nā ʻano kemika a me nā ʻano mechanical ka hopena maikaʻi loa. Hōʻike ka hōʻike metallographic e ʻoluʻolu ke kūlana o ka pā puka metala ma hope o ka hoʻopau ʻana i ka plasma.

ʻO nā ʻanuʻu ʻekolu ma luna o ka hoʻomaʻemaʻe ʻana i loko o ka lua ma hope o ka ʻeli ʻana i nā papa paʻi paʻa paʻa i hoʻonohonoho pono ʻia e Capel. Ua kālele ʻo Capel i ka papa kaapuni paʻi paʻi paʻa, ka papa palupalu, ka papa paʻa a me ka hui SMT no 15 mau makahiki, a ua hōʻiliʻili i ka ʻike loea i ka ʻoihana papa kaapuni. Manaʻo wau he mea kōkua kēia kaʻana like i nā mea a pau. Inā he mau nīnau ʻē aʻe kāu e pili ana i ka papa kaapuni, e ʻoluʻolu e ʻoluʻolu e nīnau i kā mākou hui ʻenehana ʻenehana makeup Capel e hāʻawi i ke kākoʻo ʻenehana loea no kāu papahana.
