Annealing Rolled Copper Foil: Kuvhura Kushanda Kwakawedzerwa KwemaApplication Epamusoro

Mumaindasitiri epamusoro-soro akadai sekugadzira zvinhu zvemagetsi, simba rinogona kushandiswazve, uye ndege,foiri yemhangura yakakungurutswainokosheswa nekuda kwekushanda kwayo zvakanaka, kugona kuchinjika, uye pamusoro payo pakatsetseka. Zvisinei, kana isina kuvharwa zvakanaka, foil yemhangura yakamonerwa inogona kuomeswa nebasa uye kusashanda zvakanaka, zvichideredza kushandiswa kwayo. Kuvharwa inzira yakakosha inovandudza magadzirirwo e microstructure efoil yemhangura, ichivandudza hunhu hwayo hwekushandisa zvakanyanya. Chinyorwa chino chinotarisa misimboti yekunamira, kukanganisa kwayo mashandiro echinhu, uye kukodzera kwayo zvigadzirwa zvakasiyana-siyana zvemhando yepamusoro.

1. Maitiro eKunyungudutsa: Kuchinja Maumbirwo eMicro kuti Uve neZvinhu Zvakanakisisa

Munguva yekumonera, makristaro emhangura anomanikidzwa uye anoreba, zvichiita kuti chimiro che fibrous chive chakazara nekubviswa kwechinhu uye kushushikana kwakasara. Kuomarara uku kunoita kuti kuomarara kuwedzere, kuderera kwe ductility (kureba kwe 3%-5%) chete, uye kudzikira kudiki kwe conductivity kusvika pa 98% IACS (International Annealed Copper Standard). Annealing inogadzirisa matambudziko aya kuburikidza ne "heating-holding-cooling" sequence inodzorwa:

1. Chikamu Chekudziyisa: Iyofoil yemhangurainodziya kusvika pakupisa kwayo kwe recrystallization, kazhinji pakati pe200-300°C yemhangura yakachena, kuti iite kuti atomu ifambe.
2. Chikamu Chekubata: Kuchengetedza tembiricha iyi kwemaawa maviri kusvika mana kunobvumira tsanga dzakakanganisika kuora, uye tsanga itsva, dzakafanana, dzinokura kubva pa10-30μm.
3. Danho rekutonhodza: Kutonhora kunonoka kwe ≤5°C/min kunodzivirira kuunza kushushikana kutsva.

Ruzivo Runotsigira:

• Kupisa kunodzika kunokanganisa zvakananga kukura kwezviyo. Semuenzaniso, pa250°C, zviyo zveinenge 15μm zvinowanikwa, zvichikonzera simba rekudhonza re280 MPa. Kuwedzera tembiricha kusvika 300°C kunoita kuti zviyo zvikure kusvika 25μm, zvichideredza simba kusvika 220 MPa.
• Nguva yakakodzera yekubata chinhu inokosha. Pa 280°C, kubata kwemaawa matatu kunovimbisa kuti crystallization inodarika 98%, sezvakaratidzwa ne X-ray diffraction analysis.

2. Midziyo Yepamusoro Yekunyungudutsa: Kudzivirira Kwakarurama uye Kuoxidation

Kubata zvakanaka kunoda maovheni akachengetedzwa negasi kuti ive nechokwadi chekupararira kwekupisa kwakafanana uye kudzivirira oxidation:

1. Dhizaini yeVira: Kudzora tembiricha kwakazvimirira kwenzvimbo dzakawanda (semuenzaniso, kurongeka kwenzvimbo nhanhatu) kunoita kuti kusiyana kwetembiricha muhupamhi hwefoil kurambe kuri mukati me ±1.5°C.
2. Mhepo Inodzivirira: Kuunza nitrogen yakachena kwazvo (≥99.999%) kana musanganiswa wenitrogen-hydrogen (3%-5% H₂) kunochengetedza mwero weokisijeni uri pasi pe5 ppm, zvichidzivirira kuumbwa kwema oxide emhangura (ukobvu hwe oxide layer <10 nm).
3. Sisitimu Yekutakura Zvinhu: Kutakurwa kwemaroller asina kumanikidzwa kunoita kuti foil isatsvedze. Maovheni epamusoro anobata annealing anogona kushanda nekumhanya kusvika pamamita zana nemakumi maviri paminiti, aine simba rematani makumi maviri pazuva paovheni.

Chidzidzo ChenyayaMutengi aishandisa chitofu chekupisa gasi chisina kunyorova akasangana nekupisa kwakatsvuka paganda.foil yemhangurapamusoro (oxygen yakawanda kusvika 50 ppm), zvichikonzera maburrs panguva yekucheka. Kuchinja kuenda kuchoto chemhepo chinodzivirira kwakaguma nekuoma kwenzvimbo (Ra) kwe ≤0.4μm uye kuwedzera kugona kwekucheka kusvika 99.6%.

3. Kuvandudza Mashandiro: Kubva ku "Zvinhu Zvisina Kugadzirwa zveMaindasitiri" kusvika ku "Zvinhu Zvinoshanda"

Foiri yemhangura yakasanganiswainoratidza kuvandudzika kukuru:

Izvi zvinoita kuti foil yemhangura yakasungirirwa ive yakanakira:

1. Maseketi Akadhindwa Anochinjika (FPCs): Nekureba kwefoil kunopfuura 20%, foil iyi inogona kutsungirira kutenderera kwekukombama kunopfuura 100,000, ichizadzisa zvinodiwa nemidziyo inopetwa.
2. Vaunganidzi veLithium-Ion Battery Current: Mafoil akapfava (HV<90) anodzivirira kutsemuka panguva yekuputira electrode, uye mafoil akatetepa kwazvo e6μm anochengetedza huremu hwakafanana mukati me±3%.
3. Zvikamu Zvidiki Zvikuru: Kuomarara kwenzvimbo pasi pe0.5μm kunoderedza kurasikirwa kwechiratidzo, zvichideredza kurasikirwa kwekuisa ne15% pa28 GHz.
4. Zvinhu zvekudzivirira zvemagetsi: Kufambiswa kwemhepo kwe101% IACS kunoita kuti kudzivirira kushande zvakanaka kweinenge 80 dB pa1 GHz.

4. CIVEN METAL: Tekinoroji yeAnnealing Inotungamira muIndasitiri

CIVEN METAL yafambira mberi zvakanyanya muhunyanzvi hwekugadzira annealing:

1. Kudzora Kupisa Kwakangwara: Kushandisa maalgorithms ePID ane mhinduro ye infrared, zvichiita kuti kudzorwa kwetembiricha kuve kwakarurama kwe ±1°C.
2. Kusimbiswa Kwakawedzerwa: Madziro echoto ane jira mbiri ane muripo wekumanikidzwa unochinja-chinja anoderedza kushandiswa kwegasi ne30%.
3. Kudzora Kutungamirirwa Kwezviyo: Kuburikidza ne gradient annealing, kugadzira mafoil ane kuoma kwakasiyana-siyana pakureba kwawo, ane musiyano wesimba renzvimbo kusvika ku20%, akakodzera zvikamu zvakaoma zvakadhindwa.

Kusimbiswa: CIVEN METAL's RTF-3 reverse-treated foil, post-annealing, yakasimbiswa nevatengi kuti ishandiswe mu5G base station PCBs, zvichideredza kurasikirwa kwe dielectric kusvika ku0.0015 pa10 GHz uye kuwedzera huwandu hwe transmission ne12%.

5. Mhedziso: Kukosha Kwekunamatira Mukugadzirwa KweCopper Foil

Kunyungudutsa hakungoitiki chete "kutonhodza kupisa"; ikubatanidzwa kwakaoma kwesainzi yezvinhu uye mainjiniya. Nekushandisa zvinhu zve microstructure zvakaita semiganhu yezviyo nekubviswa kwenzvimbo,foil yemhangurashanduko kubva pakushanda nesimba kuenda pakushanda nesimba, zvichitsigira kufambira mberi mukutaurirana kwe5G, mota dzemagetsi, uye tekinoroji inopfekwa. Sezvo maitiro ekuwedzera simba achichinja kuenda kuhungwaru hwakakura uye kugadzikana—sekunge CIVEN METAL inogadzira maovheni anoshandisa hydrogen achideredza kuburitswa kweCO₂ ne40%—foil yemhangura yakamonerwa yagadzirira kuvhura mikana mitsva mukushandiswa kwezvino.
