He aha ka hana o ka PCB fabrication panel?
ʻĀpana PCB
Hoʻohana nui ʻia nā papa kaapuni i paʻi ʻia ma nā ʻano like ʻole e like me ke kamaʻilio, ka mokulele, nā kaʻa, ka pūʻali koa, ka mana uila, ka mālama olakino, ka mana ʻoihana, electromechanical, a me nā kamepiula.He aha ka hana PCB?Ua kapa ʻia ka hana hou ʻana o nā huahana.Hāʻawi nā mea kūʻaiHana ʻia ʻo PCBnā palapala a me nā koi hana, a hana nā mea hana PCB i nā huahana e like me nā koi a me ka uku hoʻoili uku.ʻO ka hana PCB ʻo ia hoʻiNā mea hana PCBhana hou i nā papa kaapuni i pai ʻia e like me nā koi o ka mea kūʻai aku.
No ke aha e pono ai ka hana ʻana o PCB e hana i ka hana panel?Ma hope o ka waiho ʻana i ka pā SMT, pono anei e ʻoki ʻia i ka papa hoʻokahi?He aha ka lihi o ka papa kaapuni paʻi i hoʻohana ʻia no?ʻAʻole anei i ʻōlelo ʻia ʻo ka liʻiliʻi o ka hoʻohana ʻana o ka papa, ʻoi aku ka liʻiliʻi?ʻO ka maʻamau ka hapa nui o ka PCB fabrication e PCB panel, a ʻo ka hoʻomaka mua ʻana e hoʻonui i ka hana pono o ka laina hana SMT patch.ʻO ka PCB splicing wale nō no ka maʻalahi o ka hana.No nā mea hana PCB, ʻoi aku ka nui o ka waihona kumu o nā papa kaapuni paʻi.Hana ʻia nā papa he nui i ka manawa hoʻokahi, a laila ʻoki ʻia kēlā me kēia.Hoʻohana nui ʻia ka splicing i ka hana welding.
He nui nā hana o ka PCB panel, i kūpono i nā mea kūʻai aku e hoʻopili, kūpono no nā mea hana hana PCB e hana ma o lākou iho, a mālama i nā mea.ʻO ka hana PCB maʻamau ka nui o nā papa, e like me ʻelua-ma-hoʻokahi, ʻehā-i-hoʻokahi, a me nā mea ʻē aʻe. maoli i loko o ka tin kiʻekiʻe pai kaʻina, no ka mea, ina ka nui o kapapa kaapuni paihe nui, aneane 25s ka manawa pai.ʻO ia hoʻi, inā liʻiliʻi ka manawa o ka mīkini paʻi chip ma mua o ka mīkini paʻi solder paste, e kali nele.Mai ka hiʻohiʻona o nā pōmaikaʻi waiwai, he mea ʻino kēia.
He pono ʻē aʻe ka PCB panel.Hiki iā ia ke mālama i ka manawa ke ʻohi a kau i nā papa kaapuni PCBA, no ka mea hiki ke koho ʻia nā papa he nui a kau ʻia i ka manawa like.Hoʻopau ʻia nā hola kanaka i ka ʻohi ʻana a me ka waiho ʻana i nā mea hana.
He aha ke kumu o ka hana ʻana i ka PCB lihi?ʻO ke kumu nui o ka hoʻolālā lihi PCB ʻo ke kōkua ʻana i ka hana hui PCBA.ʻO ka laina hana SMT patch i kēia manawa he mea maʻalahi loa, a lawe ʻia nā papa e nā kāʻei a me nā kaulahao.ʻO ke kumu nui o ka lihi papa ʻo ka lawe ʻana i nā papa i kēia mau kāʻei a me nā kaulahao.Hiki iā ʻoe ke waiho i kahi ākea a puni ka papa a mai kau i nā ʻāpana uila.Pono ka hana ʻana o PCB ma ka liʻiliʻi he 5.0mm a ʻoi aku paha, no ka mea, pono e hoʻohana ke kaulahao hao o ka umu reflow i kahi kūlana hohonu ma ka lihi o ka papa, no laila aia kahi manawa e ʻAʻohe pono e hoʻolālā i ka lihi o ka papa. , inā ʻaʻole hiki i ke kāʻei a me ke kaulahao ke hōʻino i nā ʻāpana uila a puni.
