Me ka hoʻomau mau ʻana a me ka holomua o ka ʻenehana huahana uila hou, ke ulu mālie nei nā huahana uila i ke kuhikuhi o ka māmā, lahilahi, liʻiliʻi, pilikino, hilinaʻi kiʻekiʻe a me nā hana he nui.Ua hānau ʻia ka PCB alumini e like me kēia ʻano.Ua hoʻohana nui ʻia ka PCB alumini i nā kaʻa i hoʻohuihui ʻia, nā kaʻa, ka automation keʻena, nā lako uila mana kiʻekiʻe, nā lako lako mana a me nā māla ʻē aʻe me ka hoʻoheheʻe wela maikaʻi loa, ka machinability maikaʻi, ke kūpaʻa dimensional a me ka hana uila.

ʻOki ʻana → lua wili → kiʻi māmā kiʻi ʻoniʻoni maloʻo → papa nānā → etching → nānā ʻana i ka corrosion → soldermask ʻōmaʻomaʻo → silkscreen → nānā ʻōmaʻomaʻo → ka hoʻoheheʻe ʻana i ka tin → ka mālama ʻana i ke kumu kumu alumini → ka pā kuʻi → ka nānā hope → ka hoʻouna ʻana.
Nā memo no ka aluminipcb:
1. Ma muli o ke kumukūʻai kiʻekiʻe o nā mea maka, pono mākou e hoʻolohe i ka standardization o ka hana i ka hana hana e pale ai i ka poho a me nā ʻōpala i hana ʻia e nā hewa hana hana.
2. He ilihune ka pale lole o ka ili o ka pcb alumini.Pono nā mea hana o kēlā me kēia kaʻina hana e hoʻokomo i nā mīkina lima i ka wā e hana ai, a lawe mālie iā lākou e pale aku i ka ʻili ʻana i ka ʻili o ka pā a me ka ʻili kumu alumini.
3. Pono kēlā me kēia loulou hana lima e hoʻokomo i nā mīkina lima e pale aku i ka hoʻopā ʻana i ka wahi kūpono o ka pcb aluminika me nā lima e hōʻoia i ka paʻa o ka hana hana ma hope.
ʻO ke kahe kaʻina hana kūikawā o ka substrate alumini (mahele):
1. Oki
l 1).E hoʻoikaika i ka nānā ʻana i nā mea komo (pono e hoʻohana i ka ʻili alumini me ka pepa kiʻiʻoniʻoni pale) e hōʻoia i ka hilinaʻi o nā mea komo.
l 2).ʻAʻole koi ʻia ka pā palaoa ma hope o ka wehe ʻana.
l 3).E mālama mālie a hoʻolohe i ka pale ʻana i ka ʻili o ke kumu alumini (kiʻi pale).Hana maikaʻi i ka pale ma hope o ka wehe ʻana i nā mea.
2. Puka wili
l Ua like nā palena o ka wili ʻana me ka pepa FR-4.
l He koʻikoʻi loa ka ʻae ʻana o ka Aperture, 4OZ Cu e hoʻolohe i ka mālama ʻana i ka hanauna o mua.
l E wili i na lua me ka ili keleawe iluna.
3. Kiʻiʻoniʻoni maloʻo
1) Nānā mea komo: E nānā ʻia ke kiʻi pale o ka ʻili kumu alumini ma mua o ka wili ʻana i ka pā.Inā ʻike ʻia kahi pōʻino, pono e hoʻopili paʻa ʻia me ke kāʻei polū ma mua o ka mālama ʻana.Ma hope o ka pau ʻana o ka hana ʻana, e nānā hou ma mua o ka wili ʻana i ka pā.
2) ʻO ka pā wili: ʻo ka ʻili keleawe wale nō ke hana ʻia.
3) Kiʻiʻoniʻoni: e hoʻopili ʻia ke kiʻiʻoniʻoni i ke keleawe a me ke kumu alumini.E hoʻomalu i ka wā ma waena o ka pā wili a me ke kiʻiʻoniʻoni ma lalo o 1 mau minuke e hōʻoia i ka paʻa o ka mahana kiʻiʻoniʻoni.
4) Paʻi: E nānā pono i ka pololei o ka paʻi ʻana.
5) Hōʻike: Luna hoʻolaha: 7 ~ 9 mau hihia o ke koena kelu.
6) Hoʻomohala: kaomi: 20 ~ 35psi wikiwiki: 2.0 ~ 2.6m / min, pono kēlā me kēia mea hoʻohana e hoʻokomo i nā mīkina lima e hana pono ai, e pale aku i ka ʻoki ʻana i ke kiʻi pale a me ka pae kumu alumini.
4. Papa nānā
1) Pono ka ʻili o ka laina e nānā i nā mea āpau e like me nā koi MI, a he mea nui e hana pono i ka papa nānā.
2) E nānā pū ʻia ka ʻili kumu alumini, a ʻaʻole e hāʻule a pōʻino ke kiʻi maloʻo o ka ʻili kumu alumini.
Nā memo e pili ana i ka alumini substrate:
A. Pono e hoʻolohe i ka nānā ʻana i ka pilina lālā o ka pā, no ka mea, ʻaʻohe mea maikaʻi e lawe hou ʻia e wili hou, no ka mea hiki ke ʻohi ʻia ka ʻōpala me ke one (2000#) a laila lawe ʻia e wili i ka pā, komo lima i ka loulou o pili ka pā i ka hana nānā, no ka mea, ua hoʻomaikaʻi maikaʻi ʻia ka uku kūpono o ka substrate alumini!
B. I ka hihia o ka hana hoʻopau, pono e hoʻoikaika i ka mālama ʻana e hōʻoia i ka lawe ʻana maʻemaʻe a me ka pahu wai, i mea e hōʻoia ai i ka paʻa o ka hana ma hope a me ka wikiwiki o ka hana.
