1. Hoʻohana like ʻole. ʻO nā mea waiwai nui no ka hana ʻana i nā papa kaapuni he alkali- lole aniani manuahi, pepa fiber, a me ka resin epoxy.Papa aniani: mea kumu lole aniani puluniu lole, papa epoxy: he epoxy resin ka mea hoopili, FR4: pepa pulupulu pulupulu kumu kumu. ʻO nā mea ʻekolu he mau paneli fiberglass.
2. Nā kala like ʻole. ʻO ka maʻamau ka papa epoxy ma ka mākeke he phenolic epoxy, melemele. ʻAʻole ia i hoʻohana ʻia ma ke ʻano he kumu kumu o nā papa kaapuni ʻoʻoleʻa, a no nā kumu insulation uila.FR4he pepa epoxy maʻemaʻe maʻamau NEMA, a ʻo ke kala maʻamau he ʻōmaʻomaʻo ʻeleʻele, ʻo ia ke kala o ka epoxy.
3. Okoa ke ano. Loaʻa i ka papa fiberglass nā hiʻohiʻona o ke kani ʻana o ke kani, ke kani ʻana o ke kani, ka wela wela, ka mālama ʻana i ke kaiapuni, ka pale ahi a pēlā aku. Ua ʻike ʻia ʻo FR-4 ʻo ka papa fiber aniani; papa fiber aniani; FR4 papa hoʻoikaika; FR-4 papa epoxy resin; ʻO ka papa hoʻolāʻau pale ahi; papa epoxy, papa kukui FR4. Papa lole aniani epoxy; papa kaapuni drilling backing board.
Nā hiʻohiʻona o ka papa fiberglass:
ʻO nā hiʻohiʻona ʻenehana nui a me nā noi o ka papa kukui FR4 keʻokeʻo: ka hoʻokō uila uila paʻa, palahalaha maikaʻi, ʻili maʻemaʻe, ʻaʻohe lua, ʻoi aku ka mānoanoa ma mua o ka maʻamau, kūpono no nā huahana e koi ai i ka insulation uila kiʻekiʻe, e like me ka FPC reinforcement board, tin. kapuahi pale wela kiʻekiʻe, diaphragm kalapona, huila honua pololei, pahu ho'āʻo PCB, ʻeleʻele (uila) mea hoʻokaʻawale ʻokoʻa, kākoʻo hoʻolalelale. pāpaʻi, mea hoʻololi hoʻololi, kaʻa kaʻa, deflection coil terminal board, uila hoʻololi papa insulation, etc.
Papa epoxyua kapa ʻia ʻo epoxy glass fiber board. Hana ʻia ia ma ka hoʻopaʻa ʻana i ka resin epoxy a hele i nā kaʻina hana hoʻomehana a me ke kaomi. Loaʻa iā ia nā waiwai mechanical kiʻekiʻe i loko o kahi ʻano - wela kaiapuni, a me ka uila Stable hana, maikaʻi ke kūpaʻa ʻana i ka wai a me ka wela, a loaʻa nā pūʻulu epoxy ikaika, e hana i nā ʻano infusible a insoluble ma hope o ka hoʻopili ʻana me nā lāʻau lapaʻau like ʻole. Hōʻike ʻia ia e ka adhesion ikaika a me ka shrinkage ikaika.
ʻO ia hoʻi ka mea i kapa ʻia ʻo fiberglass board, i hoʻohana mau ʻia no ka uhi palupalu ʻana i ka papa kumu, a laila uhi ʻia me ka lole, ʻili, a pēlā aku e hana ai i nā mea hoʻonani nani o ka pā a me ke kaupaku. Nui loa ka noi. Loaʻa iā ia nā hiʻohiʻona o ke kani ʻana o ke kani, ke kani ʻana o ke kani, ka wela wela, ka mālama ʻana i ke kaiapuni, ka lapalapa ahi a pēlā aku.
