ʻO ka ʻenehana maikaʻi loa kekahi o nā mea hana pcb maikaʻi loa a me nā mea hoʻolako papa kaapuni paʻi ma Kina
I ka honua o ka uila, paʻi ʻia nā papa kaapuni (PCBs) i mea koʻikoʻi i ka hoʻohui ʻana a me ka mana o nā ʻāpana like ʻole. ʻO lākou ka iwi kuamoʻo o kēlā me kēia mea uila, mai nā smartphones a i nā mīkini ʻenehana. I ka hoʻolālā ʻana i kahi PCB no kahi papahana, ʻo ka mānoanoa o ka papa keleawe he mea nui e noʻonoʻo ai. ʻO nā PCB keleawe kaumaha, i ʻike ʻia he PCB keleawe mānoanoa, ua lilo i mea kaulana i ka hoʻouka ʻana i nā kaʻa ma muli o kā lākou mau hiʻohiʻona a me nā pono. Ma kēia ʻatikala, e kūkākūkā mākou no ke aha e noʻonoʻo ai i nā PCB keleawe kaumaha no kāu papahana kiʻekiʻe o kēia manawa.
He aha ka Heavy Copper PCB?
ʻO ka PCB keleawe kaumaha he papa kaapuni me kahi papa keleawe mānoanoa ʻē aʻe, ʻoi aku ma mua o 3 auneke no kēlā me kēia kapuaʻi square (oz/ft²). Ma ka hoʻohālikelike, loaʻa i nā PCB maʻamau ka mānoanoa ʻāpana keleawe o 1 oz/ft². Hoʻohana ʻia nā PCB keleawe koʻikoʻi i nā noi kahi e pono ai ke kiʻekiʻe o kēia manawa, a i ʻole ka papa e kū i ke koʻikoʻi mechanical a me ka wela.
Nā pōmaikaʻi o nā PCB keleawe kaumaha
l Kiekie o keia manawa
ʻO ka papa keleawe mānoanoa i loko o kahi PCB keleawe kaumaha e hiki ai ke kiʻekiʻe o kēia manawa. He mea kūpono kēia no nā noi mana kiʻekiʻe e like me nā lako mana, nā mea hoʻokele kaʻa, a me nā mea hana ʻoihana. Hiki i nā PCB keleawe kaumaha ke lawe i ka 20 amps a i ʻole, ke hoʻohālikelike ʻia me ka 5-10 amps maʻamau o kahi PCB maʻamau.
l Hooponopono wela
Ua ʻike ʻia nā PCB keleawe kaumaha no kā lākou hiki ke hoʻokele wela. ʻO ka papa keleawe mānoanoa e hiki ai i ka hoʻoheheʻe wela maikaʻi, e hōʻemi ana i ka hopena o ka wela a me ka hemahema o nā mea. ʻO kēia ka mea kūpono iā lākou no nā noi e koi ana i ka mana kiʻekiʻe a hoʻoulu i ka wela nui.
l Ka lōʻihi
ʻOi aku ka ikaika o nā PCB keleawe kaumaha ma mua o nā PCB maʻamau. Hāʻawi ka papa keleawe mānoanoa i ke kākoʻo mechanical ʻoi aku ka maikaʻi, e hoʻopaʻa iā lākou i ka pōʻino mai ka haʻalulu, haʻalulu, a me ka piko. ʻO kēia ka mea kūpono iā lākou no nā kaiapuni koʻikoʻi a me nā noi ʻoihana.
l Hoʻonui i ka hiki ke hoʻololi
Hāʻawi nā PCB keleawe kaumaha i ka maʻalahi hoʻolālā i hoʻohālikelike ʻia me nā PCB maʻamau. ʻO ka papa keleawe mānoanoa e hiki ai i nā hoʻolālā paʻakikī a paʻakikī, e hōʻemi ana i ka nui o ka papa. He mea kūpono kēia no nā noi i kaupalena ʻia ka wahi.
l ʻOi aku ka pono o ka hōʻailona
ʻO ka papa keleawe mānoanoa i nā PCB keleawe kaumaha e hāʻawi i ka hōʻailona hōʻailona maikaʻi. Hoʻemi kēia i ka pilikia o ka nalowale o ka hōʻailona a me ke keakea ʻana, e hopena i ka hana kaapuni i hilinaʻi a maikaʻi hoʻi.
Hoʻolālā mānoanoa keleawe no kahi PCB Copper Heavy?
Ma muli o ka mānoanoa o ke keleawe i loko o ke keleawe keleawe nui ka mānoanoa a laila maʻamau FR4 PCB, a laila e maʻalahi e warped inā ʻaʻole kūlike ka mānoanoa keleawe kekahi i kekahi i nā ʻāpana symmetrical. No ka laʻana, inā ʻoe e hoʻolālā ana i kahi PCB keleawe kaumaha 8, a laila pono ka mānoanoa keleawe o kēlā me kēia papa L8=L1, L7=L2, L6=L3, L5=L4 maʻamau.
Eia kekahi, pono e noʻonoʻo ʻia ka pilina ma waena o ka palena liʻiliʻi a me ka laulā laina liʻiliʻi, e hahai i ka lula hoʻolālā e kōkua i ka hoʻomaʻamaʻa ʻana a hoʻopōkole i ka manawa alakaʻi. Aia ma lalo nā lula hoʻolālā ma waena o lākou, ʻo LS e pili ana i ka laina laina a ʻo LW e pili ana i ka laulā laina.
Nā rula o ka lua no ka papa keleawe kaumaha
ʻO kahi puka i hoʻopaʻa ʻia (PTH) ma ka papa kaapuni i paʻi ʻia e hoʻohui i ka ʻaoʻao o luna a me lalo e hana ai i ka uila. A i ka hoʻolālā ʻana o ka PCB i nā ʻāpana keleawe he nui, pono e noʻonoʻo pono nā ʻāpana o nā lua, ʻoi aku ka nui o nā anawaena puka.
Ma ka ʻenehana maikaʻi loa, pono ke anawaena PTH haʻahaʻa loa>= 0.3mm aʻo ka annular apo keleawe he 0.15mm ma ka liʻiliʻi loa. No ka mānoanoa keleawe o ka pā o PTH, 20um-25um ma ke ʻano he paʻamau, a me 2-5OZ kiʻekiʻe (50-100um).
Nā palena kumu o ka Heavy Copper PCB
Eia kekahi mau ʻāpana kumu o ka PCB keleawe kaumaha, manaʻolana hiki ke kōkua iā ʻoe e hoʻomaopopo maikaʻi i ka hiki ʻana o ka ʻenehana maikaʻi loa.
l Mea kumu: FR4
l Ka mānoanoa keleawe: 4 OZ~30 OZ
l Ke keleawe kaumaha loa: 20~200 OZ
l Outline: Alahele, kuʻi, V-ʻoki
l ʻAila ʻulaʻula: Keʻokeʻo / ʻeleʻele / ʻulaʻula / ʻōmaʻomaʻo / ʻulaʻula (ʻAʻole maʻalahi ka paʻi ʻana i ka mask solder i ka PCB keleawe kaumaha.)
l ʻO ka hoʻopau ʻana i ka ʻili: Ke gula Immersion, HASL, OSP
l Nui Nui o ka Panel: 580*480mm (22.8"*18.9")
Nā noi o nā PCB keleawe kaumaha
Hoʻohana ʻia nā PCB keleawe kaumaha i nā ʻano noi like ʻole, me:
l Nā lako mana
l Nā mea hoʻokele kaʻa
l ʻOihana mīkini
l Mea uila kaʻa
l Aerospace a me nā ʻōnaehana pale
l Nā mea hoʻohuli lā
l kukui LED
He mea koʻikoʻi ke koho ʻana i ka mānoanoa PCB kūpono no ka kūleʻa o kekahi papahana. Hāʻawi nā PCB keleawe kaumaha i nā hiʻohiʻona kūʻokoʻa a me nā pōmaikaʻi i kūpono iā lākou no nā noi kiʻekiʻe a me ka wela. Inā makemake ʻoe e hōʻoia i ka hilinaʻi a me ka hana o kāu papahana, e noʻonoʻo e hoʻohana i nā PCB keleawe kaumaha. ʻOi aku ka ʻenehana maikaʻi loa ma mua o 16 mau makahiki o ka hana ʻana i nā PCB keleawe kaumaha, no laila ke hilinaʻi nei mākou e hiki iā mākou ke lilo i mea hoʻolako hilinaʻi loa ma Kina. Welina mai e leka uila iā mākou i kēlā me kēia manawa no nā nīnau a i ʻole nā nīnau e pili ana i nā PCB.
