metala kumu pcb 1Layer Thermoelectric Copper kumu Papa | YMSPCB
He aha ka PCB ma muli o ke keleawe?
ʻO ka PCB e pili ana i ke keleawe ka mea kūʻai nui loa i ka PCB metala , ʻoi aku ka maikaʻi o ka conductivity thermal ma mua o ka PCB alumini a me ka PCB pili hao. He kūpono no ke kaapuni alapine kiʻekiʻe a me ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa o ka hoʻololi ʻana i ka wela a me nā lako kamaʻilio pololei ʻana i ka wela a me ka ʻoihana hoʻonaninani hale.
A Metal Core Printed Circuit Board (MCPCB), i ʻike ʻia hoʻi he PCB wela a i ʻole PCB kākoʻo metala, he ʻano PCB i loaʻa kahi mea metala ma ke kumu no ka ʻāpana hoʻolaha wela o ka papa. ʻO ka metala mānoanoa (kokoke mau alumini a keleawe paha) e uhi ana i ka ʻaoʻao 1 o ka PCB. Hiki ke kuhikuhi ʻia ke kumu metala i ka metala, aia ma waena a i ʻole ma hope o ka papa. ʻO ke kumu o ke kumu o kahi MCPCB ʻo ia ka hoʻihoʻi ʻana i ka wela mai nā ʻāpana papa koʻikoʻi a i nā wahi koʻikoʻi ʻole e like me ke kākoʻo heatsink metala a i ʻole ke kumu metala. Hoʻohana ʻia nā metala kumu i ka MCPCB ma ke ʻano he ʻokoʻa i nā papa FR4 a i ʻole CEM3.
ʻO ke kumu metala o ka PCB wela hiki ke alumini (aluminum core PCB), keleawe (copper core PCB a i ʻole PCB keleawe kaumaha) a i ʻole ka hui ʻana o nā ʻāpana kūikawā. ʻO ka mea maʻamau he PCB kumu alumini. ʻO nā mea ʻē aʻe, e like me ke keleawe a i ʻole ke kila, ke noi ʻia i kekahi manawa akā ʻaʻole ʻōlelo ʻia. Paʻakikī loa nā mea metala PCB a ʻo ka ʻoki ʻana i ka PCB i mau ʻāpana liʻiliʻi hiki ke pilikia. ʻO nā manaʻo ʻē aʻe i ke koho ʻana i nā mea metala PCB nā kemika i ka hana ʻana a inā e pane ka metala iā lākou.
ʻO ka mānoanoa o nā cores metala ma nā papa kumu PCB maʻamau he 30 mil - 125 mil, akā hiki i nā papa mānoanoa a lahilahi.
Hiki ke 1 - 10 oz ka mānoanoa copper foil MCPCB. ʻO ka hōʻiliʻili ʻana o ka wela nui ma nā papa kaapuni i paʻi ʻia e alakaʻi i nā hana ʻino i nā mea hana. ʻAʻole hiki ke hoʻomaʻalili ʻia nā mea uila e hoʻoulu ai i ka nui o ka wela me ka hoʻohana ʻana i nā mea pā maʻamau. ʻO ka hoʻoluʻu hoʻoheheʻe ʻana ma o nā papa kumu metala kahi koho kūpono. I ka hoʻoheheʻe conductive, hoʻololi ʻia ka wela mai kahi ʻāpana wela i kahi ʻāpana ʻoluʻolu ma o ka hoʻopili pololei ʻana. Hoʻohana maikaʻi kēia no ka mea e ʻimi mau ana ka wela e neʻe i kekahi mea a i ʻole ka mea maʻalili. ʻO YMSPCB kahi mea hana nui o nā PCB a me nā PCBA ma Kina. Hiki i kā mākou hale hana nui ke mālama i nā kauoha liʻiliʻi-nui me ka ʻole o ka palena o nā ʻāpana liʻiliʻi; Hiki iā ʻoe ke kauoha i hoʻokahi PCB. Hāʻawi mākou i nā prototypes PCB wikiwiki a me nā lawelawe hui PCB turnkey. Hiki ke hana i nā mea a pau ma lalo o ka hale hoʻokahi, a lawe mākou i ke kuleana no kēlā me kēia kaʻina hana. Mākaukau mau kā mākou poʻe loea e kōkua iā ʻoe i ka hele ʻana mai me nā hoʻolālā maikaʻi aʻe no ka hana ʻoi aku ka maikaʻi.
Hoʻopaʻa mākou i nā PCB hana kiʻekiʻe me ka maikaʻi ʻokoʻa ma ke kumu kūʻai haʻahaʻa. Loaʻa iā mākou kahi ʻōnaehana hoʻokele maikaʻi, i hōʻoia ʻia e RoHS, IOS, a me UL. Ke hahai nei mākou i nā kūlana ʻoihana, a ʻo kā mākou ʻenehana hou e hana i nā mea āpau i ʻoi aku ka hilinaʻi a me ka wikiwiki. Hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa, a na kā mākou hui lawelawe mea kūʻai aku 24/7 e kōkua iā ʻoe.
No ke aha nā PCB metala?
ʻO ka hōʻiliʻili ʻana o ka wela nui ma nā papa kaapuni i paʻi ʻia e alakaʻi i nā hana ʻino i nā mea hana. ʻAʻole hiki ke hoʻomaʻalili ʻia nā mea uila e hoʻoulu ai i ka nui o ka wela me ka hoʻohana ʻana i nā mea pā maʻamau. ʻO ka hoʻoluʻu hoʻoheheʻe ʻana ma o nā papa kumu metala kahi koho kūpono. I ka hoʻoheheʻe conductive, hoʻololi ʻia ka wela mai kahi ʻāpana wela i kahi ʻāpana ʻoluʻolu ma o ka hoʻopili pololei ʻana. Hoʻohana maikaʻi kēia no ka mea e ʻimi mau ana ka wela e neʻe i kekahi mea a i ʻole ka mea maʻalili.
