pcb keleawe kaumaha 4 Layer (4/4/4/4OZ) Papa Soldermask Black| YMS PCB

He aha ka PCB keleawe kaumaha?

ʻO kēia PCB maʻamau ka koho mua i ka wā hiki ʻole ke pale ʻia nā au kiʻekiʻe: ʻo ka PCB keleawe mānoanoa , i hana ʻia me ka ʻenehana etching maoli. Hōʻike ʻia nā PCB keleawe mānoanoa e nā hale me nā mānoanoa keleawe mai 105 a 400 µm. Hoʻohana ʻia kēia mau PCB no nā huahana nui (kiʻekiʻe) o kēia manawa a no ka hoʻoponopono ʻana i ka hoʻokele wela. ʻO ke keleawe mānoanoa e ʻae i nā ʻāpana PCB-cross-section nui no nā ukana kiʻekiʻe o kēia manawa a paipai i ka hoʻokuʻu wela. ʻO nā hoʻolālā maʻamau he multilayer a ʻelua ʻaoʻao. 

ʻOiai ʻaʻohe wehewehe maʻamau o ka Heavy Copper, ua ʻae ʻia inā hoʻohana ʻia ʻo 3 auneke (oz) keleawe a ʻoi aku paha ma nā papa o loko a me waho o kahi papa kaapuni i pai ʻia, ua kapa ʻia ia he PCB keleawe kaumaha . ʻO kēlā me kēia kaapuni me ka mānoanoa keleawe i ʻoi aku ma mua o 4 oz no kēlā me kēia kapuaʻi square (ft2) ua hoʻokaʻawale ʻia ʻo ia ma ke ʻano he PCB keleawe kaumaha. ʻO ke keleawe nui loa, ʻo ia ka 20 oz no ft2 a 200 oz no ft2.

Ua ʻike ʻia kahi PCB keleawe kaumaha ma ke ʻano he PCB me ka mānoanoa keleawe 3 oz no ft2 a i 10 oz no ft2 i loko o nā papa waho a me loko. Hana ʻia kahi PCB keleawe kaumaha me nā kaupaona keleawe mai ka 4 oz no ft2 a i 20 oz no ft2. ʻO ka paona keleawe i hoʻomaikaʻi ʻia, me kahi pāpale mānoanoa a me ka substrate kūpono i loko o nā puka puka hiki ke hoʻololi i kahi papa nāwaliwali i kahi paepae uea lōʻihi a hilinaʻi. Hiki i nā conductors keleawe kaumaha ke hoʻonui nui i ka mānoanoa PCB holoʻokoʻa. Pono e noʻonoʻo ʻia ka mānoanoa keleawe i ka wā o ka hoʻolālā kaapuni. Hoʻoholo ʻia ka mana lawe i kēia manawa mai ka laulā a me ka mānoanoa o ke keleawe kaumaha.

ʻO ka pōmaikaʻi nui o nā papa kaapuni keleawe koʻikoʻi ko lākou hiki ke ola i ka ʻike pinepine ʻana i ka nui o ke au, ka wela kiʻekiʻe a me ke kaʻa kaʻa wela mau, hiki ke hoʻopau i ka papa kaapuni maʻamau i kekona. Loaʻa i ka papa keleawe koʻikoʻi ka mana hoʻomanawanui kiʻekiʻe, e hoʻohālikelike ʻia me nā noi i nā kūlana paʻakikī e like me, pale a me nā huahana ʻoihana aerospace.

ʻO kekahi o nā pono i hoʻohui ʻia o nā papa kaapuni keleawe kaumaha:

ʻO ka nui o nā huahana paʻakikī ma muli o kekahi mau paona keleawe ma ka papa hoʻokahi o ka circuitry

ʻO nā vias i hoʻopaʻa ʻia i ke keleawe koʻikoʻi e hele i ka manawa kiʻekiʻe ma o ka PCB a kōkua i ka hoʻoneʻe ʻana i ka wela i kahi wela o waho.

ʻO ka ʻokoʻa ma waena o kahi PCB maʻamau a me PCB keleawe mānoanoa

Hiki ke hana ʻia nā PCB maʻamau me ke kalai keleawe a me nā kaʻina hana plating. Hoʻopili ʻia kēia mau PCB e hoʻohui i ka mānoanoa keleawe i nā mokulele, traces, PTHs, a me nā pads. ʻO ka nui o ke keleawe i hoʻohana ʻia i ka hana ʻana i nā PCB maʻamau he 1oz. I ka hana ʻana i ka PCB keleawe kaumaha, ʻoi aku ka nui o ke keleawe i hoʻohana ʻia ma mua o 3oz.

No nā papa kaapuni maʻamau, hoʻohana ʻia nā ʻenehana keleawe a me nā ʻenehana plating. Eia nō naʻe, hana ʻia nā PCB keleawe kaumaha ma o ka etching differential a me ka platting step. Hana nā PCB maʻamau i nā hana maʻalahi aʻo nā papa keleawe kaumaha e hana i nā hana kaumaha.

Hana nā PCB maʻamau i ke au haʻahaʻa aʻo nā PCB keleawe kaumaha e alakaʻi i kēia manawa kiʻekiʻe. He kūpono nā PCB keleawe mānoanoa no nā noi kiʻekiʻe ma muli o kā lākou hoʻohele wela maikaʻi. ʻOi aku ka ikaika o nā PCB keleawe kaumaha ma mua o nā PCB maʻamau. Hoʻonui nā papa kaapuni keleawe kaumaha i ka hiki o ka papa i hoʻohana ʻia ai.

ʻO nā hiʻohiʻona ʻē aʻe e hoʻokaʻawale i nā PCB keleawe mānoanoa mai nā PCB ʻē aʻe

Kaumaha keleawe: ʻO kēia ka hiʻohiʻona nui o nā PCB keleawe kaumaha. ʻO ke kaumaha keleawe e pili ana i ke kaumaha o ke keleawe i hoʻohanaʻia ma kahi kapuaʻi kapuaʻi. Ana pinepine ia keia kaumaha ma na auneke. Hōʻike ia i ka mānoanoa o ke keleawe ma ka papa.

Nā papa waho: E pili ana kēia i nā ʻāpana keleawe waho o ka papa. Hoʻopili pinepine ʻia nā mea uila i nā papa waho. Hoʻomaka nā papa o waho me ke keleawe keleawe i uhi ʻia me ke keleawe. Kōkua kēia i ka hoʻonui ʻana i ka mānoanoa. Hoʻonohonoho mua ʻia ke kaumaha keleawe o nā papa waho no nā hoʻolālā maʻamau. Hiki i ka mea hana PCB keleawe kaumaha ke hoʻololi i ke kaumaha a me ka mānoanoa o ke keleawe e kūpono i kāu koi.

Nā ʻāpana o loko: ʻO ka mānoanoa dielectric, a me ka nui keleawe o nā ʻāpana o loko, ua hoʻonohonoho mua ʻia no nā papahana maʻamau. Eia naʻe, hiki ke hoʻololi i ke kaumaha keleawe a me ka mānoanoa o kēia mau papa ma muli o kāu mau pono.

Hoʻohana ʻia nā PCB keleawe kaumaha no nā kumu he nui e like me ka transformers planar, dissipation wela, ka hāʻawi ʻana i ka mana kiʻekiʻe, nā mea hoʻololi mana, a me nā mea ʻē aʻe.

Hoʻohana pū ʻia nā papa kaapuni keleawe nui i:

Nā lako mana, nā mea hoʻololi mana

Māhele mana

ʻO YMS Heavy copper PCB nā mana hana:
