Kurapa Kwekubviswa Kwemafuta Kwefoiri Yemhangura Yakamonerwa: Maitiro Ekutanga Uye Kuvimbisa Kwakakosha Kwekuputira uye Kushanda Kwekupisa Kwemafuta

Foiri yemhangura yakamonerwachinhu chakakosha muindasitiri yemagetsi, uye kuchena kwayo pamusoro nemukati kunoratidza zvakananga kuvimbika kwemaitiro ekudzika senge kuputira uye kupisa. Chinyorwa chino chinoongorora nzira iyo kurapwa kwekubvisa mafuta kunogadzirisa mashandiro efoiri yemhangura yakamonerwa kubva pakugadzira uye pakushandisa. Ichishandisa data chaiyo, inoratidza kugona kwayo kugadzirisa mamiriro ekupisa kwakanyanya. CIVEN METAL yakagadzira nzira yekubvisa mafuta yakadzika iyo inoputsa zvipingamupinyi zveindasitiri, ichipa mhinduro dzefoiri yemhangura dzakavimbika kwazvo dzekugadzira elektroniki yepamusoro.

1. Chinhu Chikuru Chekubvisa Mafuta: Kubviswa Kwemafuta Kaviri Pamusoro Uye Emukati

1.1 Matambudziko eOiri Yasara muKugadzika

Munguva yekugadzira foil yemhangura yakamonerwa, ingots dzemhangura dzinofamba matanho akawanda ekumonera kuti dzigadzire foil. Kuti kuderedza kupisa kwekukweshana uye kupera kweroli, mafuta ekuzora (akadai semafuta emaminerari nemaesters ekugadzira) anoshandiswa pakati pemaroli nefoil yemhanguraZvisinei, maitiro aya anotungamira mukuchengetedza mafuta kuburikidza nenzira mbiri huru:

• Kunyungudutsa pamusoro: Kana yamanikidzwa, firimu remafuta re micron-scale (0.1-0.5μm gobvu) rinonamira pamusoro pe copper foil.
• Kupinda mukati: Munguva yekutenderera kwechinhu, jira remhangura rinoita zvikanganiso zvidiki-diki (zvakadai sekubuda kwechinhu uye kudonha kwechinhu), zvichibvumira mamorekuru emafuta (C12-C18 hydrocarbon chains) kupinda mufoil kuburikidza ne capillary action, kusvika pakadzika kwe1-3μm.

1.2 Miganho yeNzira Dzekuchenesa Dzechinyakare

Nzira dzemazuva ano dzekuchenesa pamusoro (semuenzaniso, kugeza nealkaline, kupukuta nedoro) kubvisa mafuta epamusoro chete, zvichiita kuti huwandu hwekubvisa huve hweanenge70-85%, asi hazvishande pakurwisa mafuta anonyudzwa mukati. Ruzivo rwekuyedza runoratidza kuti pasina kubvisa mafuta akadzika, mafuta emukati anobudazve pamusoro mushure mekungeMaminetsi makumi matatu pa150°C, nehuwandu hwekudzoserwazve kwemari0.8-1.2g/m², zvichikonzera "kusvibiswa kwechipiri."

1.3 Kubudirira Kwetekinoroji Mukubvisa Mafuta Zvakadzika

CIVEN METAL inoshandisa kambani ye"Kubviswa kwemakemikari + kushandiswa kwe ultrasonic"maitiro ekubatanidza:

1. Kubviswa kwemakemikari: Chinhu chinogadzirisa chelating (pH 9.5-10.5) chinoora mamorekuru emafuta ane chain refu, zvichiita kuti pave nemacomplex anonyungudika mumvura.
2. Rubatsiro rweUltrasonic: 40kHz high-frequency ultrasound inogadzira cavitation effects, ichipwanya simba rekubatanidza pakati pemafuta emukati ne copper lattice, zvichiita kuti grisi ishande zvakanaka.
3. Kuomesa ne vacuum: Kukurumidza kupera mvura mumuviri pa -0.08MPa kumanikidzwa kusina kunaka kunodzivirira oxidation.

Maitiro aya anoderedza mafuta akasara kusvika≤5mg/m²(kusangana nezvinodiwa zveIPC-4562 zve ≤15mg/m²), zvichizadzisaKubudirira kwekubvisa >99%yemafuta anonyudzwa mukati.

2. Kukanganisa Kwakananga Kwekubvisa Mafuta Pakuputira uye Maitiro Ekupisa

2.1 Kuvandudzwa kweKunamira muKushandisa Kupenda

Zvinhu zvekuputira (zvakadai sePI glues uye photoresists) zvinofanirwa kuumba mabhondi e-molecular-level nefoil yemhanguraMafuta akasara anotungamira kumatambudziko anotevera:

• Simba rekubatana kwepaso rakaderedzwa: Kusagadzikana kwemafuta mumvura kunowedzera kona yekubatana kwemhinduro dzekuputira kubva15° kusvika 45°, zvinodzivisa kunyorova.
• Kubatanidzwa kwemakemikari kwakadziviswa: Girasi iri rinovhara mapoka ehydroxyl (-OH) pamusoro pemhangura, zvichidzivirira kusangana nemapoka anoshanda neresin.

Kuenzanisa Kushanda kweCopper Foil Yakabviswa Mafuta vs. Regular Copper Foil:

2.2 Kuvimbika Kwakawedzerwa muThermal Lamination

Munguva yekuputira mafuta pakupisa kwakanyanya (180-220°C), mafuta akasara mufoil yemhangura yenguva dzose anokonzera kutadza kwakawanda:

• Kuumbwa kwebhururu: Girazi rakapfava rinogadziraMabhurumu e10-50μm(huwandu hwezvinhu >50/cm²).
• Kupatsanurwa kwezvikamu zvakasiyana: Girazi rinoderedza simba revan der Waals pakati pe epoxy resin ne copper foil, zvichideredza simba reganda ne30-40%.
• Kurasikirwa neDielectric: Girisi isina mafuta inokonzera kuchinja-chinja kwe dielectric nguva dzose (Dk variation >0.2).

Mushure meMaawa 1000 ekukwegura kwe85°C/85% RH, CIVEN SITELFoiri yemhangurazviratidziro:

• Kuwanda kwebubble: <5/cm² (avhareji yeindasitiri >30/cm²).
• Simba rekusvuura: Inochengetedza1.6N/cm(kukosha kwekutanga1.8N/cm, mwero wekuora kwemuviri uri 11% chete.
• Kugadzikana kweDielectric: Kusiyana kweDk ≤0.05, musanganoZvinodiwa zve5G millimeter-wave frequency.

3. Chinzvimbo Cheindasitiri uye Chinzvimbo Chekuenzanisa cheCIVEN METAL

3.1 Matambudziko Eindasitiri: Kurerutsa Maitiro Anokonzerwa Nemari

Kupera90% yevagadziri vemafoil emhangura akakungurutswanyore kugadzirisa kuti uderedze mari, uchitevera nzira yekushanda yakajairwa:

Kutenderedza → Kugeza Nemvura (Na₂CO₃ solution) → Kuomesa → Kumonera

Nzira iyi inobvisa mafuta epamusoro chete, nekuchinja-chinja kwe resistivity yekumusoro mushure mekugezwa±15%(Maitiro eCIVEN METAL anoenderera mberi mukati me±3%).

3.2 Sisitimu yeCIVEN METAL yekudzora hunhu "isina chikanganiso"

• Kutarisa online: Kuongororwa kweX-ray fluorescence (XRF) kuti zvionekwe panguva chaiyo zvinhu zvakasara pamusoro (S, Cl, nezvimwewo).
• Kuyedzwa kwekukwegura nekukurumidza: Kutevedzera zvakanyanyisa200°C/24awamamiriro ezvinhu ekuona kuti mafuta haadzokeri zvakare.
• Kutevedza kwakazara kwemaitiro: Rori rega rega rine kodhi yeQR inobatanidza32 makiyi ekugadzirisa maitiro(semuenzaniso, tembiricha yekubvisa mafuta, simba re ultrasonic).

4. Mhedziso: Kurapa Kubvisa Mafuta—Hwaro hweKugadzira Magetsi Epamusoro-soro

Kubvisa mafuta zvakanyanya pa foil yemhangura yakamonerwa hakusi kungovandudza maitiro chete asi kugadzirisa ramangwana kuti rienderane nekushandiswa mune ramangwana. Tekinoroji yeCIVEN METAL inovandudza kuchena kwe foil yemhangura kusvika padanho reatomu, zvichipavimbiso yehuwandu hwezvinhuyekubatana kwehuwandu hwakanyanya (HDI), matunhu anochinjika emotokari, nedzimwe nzvimbo dzepamusoro-soro.

MuNguva ye5G neAIoT, makambani chete ndiwo ari kugonamatekinoroji ekuchenesa epakatizvinogona kukurudzira hunyanzvi hwemangwana muindasitiri yefoil yemhangura yemagetsi.
