Hoʻomaʻamaʻa Degreasing o Rolled Copper Foil: Core Process and Key Assurance for Coating and Thermal Lamination Performance

Pepa keleawe i ʻōwili ʻiaHe mea koʻikoʻi ia i ka ʻoihana kaapuni uila, a ʻo kona ʻili a me ka hoʻomaʻemaʻe kūloko e hoʻoholo pololei i ka hilinaʻi o nā kaʻina o lalo e like me ka uhi ʻana a me ka lamination thermal. Hoʻopili kēia ʻatikala i ke ʻano hana e hoʻomaʻamaʻa ai ka degreasing i ka hana o ka pahu keleawe i ʻōwili ʻia mai nā hiʻohiʻona hana a me ka noi. Ke hoʻohana nei i ka ʻikepili maoli, hōʻike ia i kona hiki ke hoʻololi i nā hiʻohiʻona hoʻoili wela kiʻekiʻe. Ua hoʻomohala ʻo CIVEN METAL i kahi kaʻina hoʻoheheʻe hohonu hohonu e wāwahi ana i nā bottlenecks o ka ʻoihana, e hāʻawi ana i nā hopena copper foil hilinaʻi nui no ka hana uila kiʻekiʻe.

1. ʻO ke kumu o ke kaʻina hana Degreasing: Wehe ʻelua o ka ʻili a me ka momona o loko

1.1 Ke koena aila pilikia ma ke kaʻina hana

I ka wā o ka hana ʻia ʻana o ka pepa keleawe i ʻōwili ʻia, hoʻohana ʻia nā ingots keleawe i nā ʻanuʻu ʻōwili he nui e hana i nā mea foil. No ka hōʻemi ʻana i ka wela a me ka ʻōwili ʻana, hoʻohana ʻia nā lubricants (e like me nā ʻaila mineral a me nā esters synthetic) ma waena o nā ʻōwili a me nāpepa keleaweʻilikai. Eia nō naʻe, alakaʻi kēia kaʻina hana i ka paʻa ʻana o ka momona ma nā ala kumu ʻelua:

• Hoʻopili i ka ʻili: Ma lalo o ke kaomi ʻana, ʻo kahi kiʻi ʻaila micron-scale (0.1-0.5μm mānoanoa) pili i ka ʻili keleawe keleawe.
• Komo i loko: I ka wā o ka rolling deformation, hoʻomohala ka lattice keleawe i nā hemahema microscopic (e like me nā dislocations a me nā voids), e ʻae ana i nā molekala momona (C12-C18 hydrocarbon kaulahao) e komo i ka foil ma o ka hana capillary, a hiki i ka hohonu o 1-3μm.

1.2 Nā palena o nā ʻano hoʻomaʻemaʻe kuʻuna

ʻO nā ʻano hana hoʻomaʻemaʻe ʻili maʻamau (e laʻa, holoi alkaline, holoi waiʻona) wehe wale i nā kiʻiʻoniʻoni ʻaila ma luna wale nō, e loaʻa ana ka nui o ka wehe ʻana ma kahi o kahi.70-85%, akā ʻaʻole kūpono i ka momona i komo i loko. Hōʻike nā ʻikepili hoʻokolohua me ka ʻole o ka degreasing hohonu, puka hou ka ʻaila kūloko ma ka ʻili ma hope30 mau minuke ma 150 ° C, me ka helu hoʻopaʻa hou ʻana o0.8-1.2g/m², ke kumu o ka “contamination lua”.

1.3 Nā Kūlana ʻenehana i ka Degreasing Hohonu

Hoʻohana ʻo CIVEN METAL i kahi"ka hoʻoneʻe kemika + hoʻōla ultrasonic"kaʻina hana hui:

1. Wehe kemika: Hoʻoheheʻe ʻia kahi mea hana chelating maʻamau (pH 9.5-10.5) i nā molekole momona kaulahao lōʻihi, e hana ana i nā paʻakikī hiki ke hoʻoheheʻe ʻia i ka wai.
2. Kōkua kani kani: 40kHz kiʻekiʻe-frequency ultrasound hoʻopuka i nā hopena cavitation, e uhaki ana i ka ikaika paʻa ma waena o ka momona kūloko a me ka lattice keleawe, e hoʻonui ai i ka pono o ka hoʻoheheʻe ʻana i ka momona.
3. Hoʻomaloʻo maloʻo: ʻO ka wai maloʻo wikiwiki ma -0.08MPa ke kaomi maikaʻi ʻole e pale i ka hoʻoheheʻe ʻana.

Hoʻemi kēia kaʻina hana i ke koena momona i≤5mg/m²(e hui ana i nā kūlana IPC-4562 o ≤15mg/m²), e loaʻa ana>99% ka pono weheno ka hamo i loko.

2. Ka hopena pololei o ka hoʻomaʻamaʻa ʻana i ka degreasing ma luna o nā kaʻina hana hoʻoheheʻe a me ka wela wela

2.1 Hoʻonui i ka hoʻopili ʻana i nā noi uhi

Pono nā mea hoʻopili (e like me nā PI adhesives a me nā photoresists) e hana i nā paʻa molecular-level mepepa keleawe. ʻO ke koena grease alakaʻi i nā pilikia penei:

• Hoʻemi i ka ikehu interface: Hoʻonui ka hydrophobicity o ka momona i ka huina pili o nā ʻoluʻolu uhi mai15° a 45°, keakea ana i ka pulu.
• Hoʻopaʻa ʻia kemika: Hoʻopili ka papa momona i nā pūʻulu hydroxyl (-OH) ma ka ʻili keleawe, e pale ana i nā hopena me nā hui ikaika resin.

Ka Hoʻohālikelike Hana o Degreased vs. Regular Copper Foil:

2.2 Hoʻonui i ka hilinaʻi ma ka Lamination Thermal

I loko o ka lamination wela wela (180-220°C), ke koena o ka momona i loko o ka pahu keleawe maʻamau e alakaʻi i nā hemahema he nui:

• Hoʻohuhū: Hoʻokumu ʻia ka momona momona10-50μm ʻōhū(ka mānoanoa >50/cm²).
• delamination interlayer: Hoʻemi ka momona i nā ikaika van der Waals ma waena o ka epoxy resin a me ka pahu keleawe, e hoʻemi ana i ka ikaika o ka peel e30-40%.
• Pohō dielectric: ʻO ka momona manuahi ka mea e hoʻololi mau ai ka dielectric (Dk variation >0.2).

Ma hope1000 hola o 85°C/85% RH kahiko, CIVEN METALPepa keleawenā hōʻike:

• ʻAi ʻeleʻele: <5/cm² (awelika ʻoihana >30/cm²).
• Ka ikaika ʻili: Mālama1.6N/cm(waiwai mua1.8N/cm, ka helu degradation wale nō 11%).
• Paʻa dielectric: Dk hoʻololi ≤0.05, halawai5G millimeter-hawewe pono alapinepine.

3. Kūlana Kūlana a me ke Kūlana Kūlana o CIVEN METAL

3.1 Nā Luʻi Hana: Hoʻomaʻamaʻa Kaʻina Hana Kūʻai

Pau90% o nā mea hana keleawe keleawe i ʻōwili ʻiae hoʻomaʻamaʻa i ka hana ʻana e hōʻemi i nā kumukūʻai, ma muli o ke kaʻina hana maʻamau:

Kaʻa ʻana → Holoi wai (Na₂CO₃ solution) → Hoʻomaloʻo → Winding

Hoʻopau wale kēia ʻano hana i ka momona o ka ʻili, me ka fluctuations resistivity ma hope o ka holoi ʻana±15%(Ke mālama nei ke kaʻina hana a CIVEN METAL i loko±3%).

3.2 ʻO ka Pūnaehana Mana Pono o CIVEN METAL "Zero-Defect".

• Nānā pūnaewele: X-ray fluorescence (XRF) kālailai no ka 'ike manawa maoli i nā mea koena o ka ili (S, Cl, etc.).
• Nā hoʻāʻo ʻelemakule wikiwiki: Hoʻohālikelike i ke kiʻekiʻe200°C/24hnā kūlana e hōʻoia i ka puka hou ʻana o ka momona ʻole.
• Hiki ke hoʻopaʻa inoa piha: Loaʻa i kēlā me kēia ʻōwili kahi code QR e pili ana i32 kaʻina hana kī(e laʻa, degreasing wela, ultrasonic mana).

4. Ka hopena: Degreasing Treatment—The Foundation of High-End Electronics Manufacturing

ʻO ka hoʻomaʻemaʻe hohonu ʻana o ka pepa keleawe i ʻōwili ʻia ʻaʻole ia he hoʻomaikaʻi kaʻina hana akā he hoʻololi noʻonoʻo i mua i nā noi e hiki mai ana. Hoʻonui ka ʻenehana holomua o CIVEN METAL i ka hoʻomaʻemaʻe keleawe keleawe i kahi pae atomika, hāʻawihōʻoia pae waiwaino ka meanā pilina pili kiʻekiʻe (HDI), nā kaʻa kaʻa hikiwawe, a me nā kahua kiʻekiʻe ʻē aʻe.

I ka5G a me AIoT manawa, ʻo nā ʻoihana wale nō ka hakuʻenehana hoʻomaʻemaʻe kumuhiki ke hoʻokele i nā mea hou i ka wā e hiki mai ana i ka ʻoihana keleawe keleawe uila.
