Kaulana ia nā papa kaapuni i paʻi ʻia (PCBs) kahi māhele o ka ʻaneʻane o nā pono uila a me nā pono uila. Loaʻa nā ʻano o PCB i nā ʻano hoʻonohonoho like ʻole a me nā papa, e pili ana i nā koi noi. Loaʻa paha i ka PCB a ʻaʻohe paha mea nui o ka hao. Hana ʻia ka hapa nui o nā PCB kumu nui mai ka aluminika, ʻoiai nā PCB maʻamau i hana ʻia mai nā substrates non-metallic e like me ka ceramic, plastic, a me fiberglass. Ma muli o ke ʻano o ke kūkulu ʻia ʻana, aia kekahi mau ʻokoʻa ma waena o nā pā alumini a me nā PCB maʻamau. ʻO wai ka mea ʻoi aku? ʻO nā ʻano PCB ʻelua e kūpono i kāu koi noi? E ʻimi i ka mea like ma aneʻi.

Hoʻohālikelike a me ka ʻike: Aluminium me nā PCB maʻamau

E hoʻohālikelike i ka alumini i nā PCB maʻamau, he mea nui e noʻonoʻo mua i kāu koi noi. Ma waho o ka hoʻolālā, ka maʻalahi, ka moʻohelu kālā, a me nā manaʻo ʻē aʻe, he mea nui like ia. No laila, eia kekahi ʻike hou aʻe e pili ana i nā PCB maʻamau a me nā alumini e kōkua iā ʻoe e hoʻoholo i ka PCB āu e pono ai.

Nā ʻike hou aʻe e pili ana i nā PCB maʻamau

E like me ka manaʻo o ka inoa, hana ʻia nā PCB maʻamau i nā hoʻonohonoho maʻamau a hoʻohana nui ʻia. Hana mau ʻia kēia mau PCB mai nā substrates FR4 a loaʻa ka mānoanoa maʻamau o kahi o 1.5mm. Kūpono nui lākou a loaʻa ka lōʻihi waena. No ka mea he alakaʻi maikaʻi ʻole nā ​​mea substrate o nā PCB maʻamau, loaʻa iā lākou ka lamination keleawe, ka pale solder e pale ana i ke kiʻi ʻoniʻoni, a me ka paʻi paʻi ʻana i mea e alakaʻi ai lākou. Hiki i kēia mau mea ke lilo i hoʻokahi, pālua, a i ʻole multilayer. ʻO ka ʻaoʻao hoʻokahi no nā pono pono e like me ka calculator. Hoʻohana ʻia nā hāmeʻa papa i kekahi mau mīkini paʻakikī, e like me nā kamepiula. No laila, kaukaʻi ʻia i ka helu o nā mea a me nā papa i hoʻohana ʻia, hoʻohana ʻia ia i nā hāmeʻa maʻalahi a paʻakikī hoʻi. Most FR4 plates are not thermally or thermally resistant, so direct exposure to high temperatures must be avoided. A ʻo kahi hopena, loaʻa iā lākou nā poho wela a i ʻole nā ​​kīʻaha piha i ke keleawe e pale ai i ka wela mai ke komo ʻana i ke kaapuni. Hiki iā ʻoe ke hōʻalo i ka hoʻohana ʻana i nā PCB maʻamau a koho i nā PCBS alumini ke koi ʻole ʻia nā mahana kiʻekiʻe e hana i nā mahana wela loa. Eia nō naʻe, inā kūpaʻa nā makemake o kāu noi, hoʻonoho maikaʻi ʻia ʻoe e koho i nā PCB maʻamau o fiberglass i maikaʻi a maikaʻi hoʻi.

ʻO Aluminium PCB e like me kekahi PCB ʻē aʻe i hoʻohana ʻia ai ka alumini ma ke ʻano he substrate. Hoʻohana ākea lākou i nā noi he nui e hana ana i nā wahi ʻoʻoleʻa a me nā mahana wela loa. Akā ʻaʻole lākou e hoʻohana ʻia i nā hoʻolālā paʻakikī e koi ai e hoʻokomo i nā mea he nui. ʻO Aluminium kahi alakaʻi maikaʻi o ka wela. Eia nō naʻe, eia nō i kēia mau PCB ka paʻi paʻi, keleawe a me nā papa pale pale solder. I kekahi manawa hiki ke hoʻohana ʻia ke alumini ma ke ʻano he substrate i hui pū ʻia me kekahi mau substrates hana ʻole ʻē aʻe, e like me nā olonā aniani. ʻO ka hapa nui o ka Aluminium PCB a ʻelua paha ʻaoʻao. ʻAʻohe kā lākou papa-maha. No laila, ʻoiai he mau mea hoʻokele pumehana lākou, ke kau nei ka papa o nā alumini PCB i kāna mau pilikia ponoʻī. Hoʻohana ākea lākou i nā ʻōnaehana kukui LED i loko a i waho hoʻi. ʻAno lākou a kōkua i ka hōʻemi ʻana i ka hopena o ka nohona.
