Aluminum PCB Kaʻina Hana Hana

Aluminum PCB Manufacturing ProcessThe manufacturing process of aluminika PCB with OSP surface finish: Cutting → Drilling → Circuit → Acid/ alkaline etching → Solder Mask → Silkscreen → V-cut → PCB Test → OSP → FQC → FQA → Packaging → Delivery.

ʻO ke kaʻina hana o ka PCB aluminika me ka hoʻopau ʻana o ka ʻili HASL: ʻoki → Drilling → Circuit → Acid / alkaline etching → Solder Mask → Silkscreen → HASL → V-cut → PCB Test → FQC → FQA → Packaging → Delivery.

Hiki iā YMSPCB ke hāʻawi i ka PCB kumu alumini me ke kaʻina hana hoʻopau like me FR-4 PCB: Immersion Gold / thin / silver, OSP, etc.

I ka hana ʻana i kahi PCB alumini, ua hoʻohui ʻia kahi ʻāpana lahilahi o ka dielectric ma waena o ka papa kaapuni a me ka papa kumu. ʻO kēia papa o ka dielectric ka mea hoʻokalakupua uila, a me ka thermally conductive. Ma hope o ka hoʻohui ʻana i ka papa dielectric, ua kālai ʻia ka ʻāpana kaapuni a i ʻole ka pahu keleawe

Hoolaha

1. E kau i nā papa i loko o ka hīnaʻi-papa a i ʻole e hoʻokaʻawale iā lākou me ka pepa a i ʻole ka ʻili i mea e pale ai i nā ʻōpala i ka wā o ka lawe ʻana i ka hana holoʻokoʻa.

2. ʻAʻole ʻae ʻia ka hoʻohana ʻana i ka pahi e ʻoki i kahi papa insulated i kekahi kaʻina hana i ka wā o ka hana holoʻokoʻa.

3. No nā papa i haʻalele ʻia, ʻaʻole hiki ke wili ʻia ka mea kumu akā ua kaha ʻia me ka "X" e ka peni hinu.

4. Pono ka nānā ʻana i ke ʻano holoʻokoʻa no ka mea ʻaʻohe ala e hoʻoponopono ai i ka pilikia kumu ma hope o ka etching.

5. E hana i nā māka IQC 100% no nā papa puka waho e like me nā kūlana o kā mākou hui.

6. E hōʻuluʻulu i nā papa kīnā ʻole (e like me ka waihoʻoluʻu ʻulaʻula a me nā ʻōpala o ka ʻili AI) e hana hou ʻia.

7. Pono e hoʻomaopopo ʻia kekahi pilikia i ka wā o ka hana ʻana i nā limahana ʻenehana pili i ka manawa e hoʻoholo ai.

8. Pono e hana pono nā kaʻina hana a pau ma muli o nā koi.

ʻIke pū ʻia nā papa kaapuni paʻi alumini he PCB kumu metala a loaʻa i nā laminates metala i uhi ʻia e nā papa kaapuni keleawe foil. Hana ʻia lākou me nā pā kila i hui pū ʻia me ka aluminika, ka magnesium a me ka silumin (Al-Mg-Si). Hāʻawi nā Aluminum PCB i ka hoʻokaʻawale uila maikaʻi loa, maikaʻi ka wela wela a me ka hana machining kiʻekiʻe, a ʻokoʻa lākou mai nā PCB ʻē aʻe ma nā ʻano koʻikoʻi.

Aluminum PCB Papa

 

KA PAPA KUMU

Aia kēia papa i kahi substrate aluminika. ʻO ka hoʻohana ʻana i ka alumini e hana i kēia ʻano PCB i koho maikaʻi loa no ka ʻenehana ma waena o ka lua, i kūkākūkā ʻia ma hope.

KA PAPA INSULATION THERMAL

He mea koʻikoʻi kēia ʻāpana o ka PCB. Loaʻa iā ia kahi polymer ceramic i loaʻa nā waiwai viscoelastic maikaʻi loa, kūpaʻa wela nui a pale i ka PCB i nā koʻikoʻi mechanical a me ka wela.

KA PAPA KAAPUNI

Aia ma ka papa kaapuni ka foil keleawe i olelo mua ia. ʻO ka mea maʻamau, hoʻohana nā mea hana PCB i nā pahu keleawe mai kahi a 10 auneke.

KA PAPA DIELECTRIC

Hoʻopili ka papa dielectric o ka insulation i ka wela i ke kahe ʻana o kēia manawa ma nā kaapuni. Hoʻololiʻia kēia i ka papa alumini, kahi i hoʻopuehuʻia ai ka wela.

ʻO ka loaʻa ʻana o ka puka māmā kiʻekiʻe loa e hiki ke hopena i ka hoʻonui ʻana i ka wela. ʻO nā PCB me ka hoʻomaikaʻi ʻana i ka wela wela e hoʻolōʻihi i ke ola o kāu huahana i hoʻopau ʻia. E hāʻawi ka mea hana kūpono iā ʻoe i ka pale ʻoi aku ka maikaʻi, ka hoʻemi ʻana i ka wela a me ka hilinaʻi ʻāpana. Ma YMS PCB, paʻa mākou iā mākou iho i nā kūlana kiʻekiʻe kiʻekiʻe a me ka maikaʻi o kāu mau papahana.
