Muindasitiri yemazuva ano yemagetsi, ma substrates eceramic anoshandiswa zvakanyanya seakakosha emagetsi ekurongedza zvinhu mumagetsi semiconductors, mwenje we LED, ma module emagetsi, uye mamwe minda. Kuwedzera mashandiro uye kuvimbika kweceramic substrates, iyo DPC (Direct Plating Copper) maitiro abuda seyakanyanya kushanda uye yakanyatso vhara tekinoroji, ikava musimboti muitiro mukugadzira ceramic substrate.
No.1 Chii chinonziDPC Coating process?
Sezvinoratidzwa nezita racho, iyo DPC yekupfekedza maitiro inosanganisira yakananga kupfekedza mhangura pamusoro peiyo ceramic substrate, kukunda zvipimo zvehunyanzvi zvechinyakare mhangura foil yekunamatira nzira. Kuenzaniswa neyakajairwa nzira dzekubatanidza, iyo DPC yekupfekedza maitiro inovandudza zvakanyanya kunamatira pakati pemhangura layer uye ceramic substrate uku ichipa yakakwira kugadzirwa kwekuita uye hukuru hwemagetsi kuita.
MuDPC yekuputira maitiro, iyo mhangura yekuputira layer inoumbwa pane ceramic substrate kuburikidza nemakemikari kana electrochemical maitiro. Iyi nzira inoderedza delamination nyaya dzinowanzo onekwa mune yechinyakare bonding maitiro uye inobvumira kudzora chaiko pamusoro pekushanda kwemagetsi, kusangana nekuwedzera kuomarara kwezvido zveindasitiri.
No.2 DPC Coating Process Flow
Iyo DPC maitiro ane akati wandei akakosha matanho, imwe neimwe yakakosha kumhando uye kuita kwechigadzirwa chekupedzisira.
1. Laser Drilling
Laser drilling inoitwa paceramic substrate zvinoenderana nedhizaini madhizaini, kuve nechokwadi chechokwadi chegomba chinzvimbo uye zviyero. Iyi nhanho inofambisa inotevera electroplating uye yedunhu pateni kuumbwa.
2. PVD Coating
Physical Vapor Deposition (PVD) tekinoroji inoshandiswa kuisa firimu rakatetepa remhangura pane ceramic substrate. Iyi nhanho inokwidziridza mashandiro emagetsi uye ekupisa kweiyo substrate uku uchivandudza kunamatira kwepamusoro, kuve nechokwadi chemhando yeinotevera electroplated mhangura layer.
3. Electroplating Thickening
Kuvaka pamusoro pePVD coating, electroplating inoshandiswa kukora mhangura. Iyi nhanho inosimbisa kusimba uye conductivity yemhangura layer kuti isangane nezvinodiwa zvepamusoro-simba maapplication. Ukuru hwemhangura yemhangura inogona kugadziriswa zvichienderana nezvinodiwa chaizvo.
4. Circuit Patterning
Photolithography uye makemikari etching maitiro anoshandiswa kugadzira chaiwo edunhu mapatani pamhangura layer. Iyi nhanho yakakosha pakuona kufambiswa kwemagetsi uye kugadzikana kwedunhu.
5. Solder Mask uye Kumaka
A solder mask layer inoshandiswa kuchengetedza nzvimbo dzisina-conductive dzedunhu. Iyi nhanho inodzivirira mapfupi maseketi uye inosimudzira iyo insulation properties ye substrate.
6. Surface Treatment
Kucheneswa kwepamusoro, kukwenenzverwa, kana kurapa kwekupotera kunoitwa kuti pave nechiso chakatsetseka uye kubvisa chero tsvina inogona kukanganisa kushanda. Kurapa kwepamusoro zvakare kunatsiridza kushorwa kweiyo substrate.
7. Laser Shaping
Chekupedzisira, laser processing inoshandiswa kupedzisa kupedzisa, kuve nechokwadi chekuti substrate inosangana nedhizaini maererano nechimiro uye saizi. Iyi nhanho inopa yakakwirira-chaiyo machining, kunyanya kune yakaoma-yakaumbwa zvikamu zvinoshandiswa mumagetsi uye mukati mekushandisa.
No.3 Zvakanakira DPC Coating Process
Iyo DPC yekuvhara maitiro inopa akati wandei akakosha mabhenefiti mukugadzirwa kweceramic substrate, kusanganisira:
1. High Adhesion Strength
Iyo DPC maitiro inogadzira chisungo chakasimba pakati pemhangura yemhangura uye ceramic substrate, inovandudza zvakanyanya kusimba uye peel kuramba kwemhangura layer.
2. Superior Electrical Performance
Copper-plated ceramic substrates inoratidzira yakanakisa magetsi uye yekupisa conductivity, inonyatso kusimudzira kushanda kwemagetsi zvikamu.
3. High Precision Control
Iyo DPC maitiro inobvumira kutonga kwakaringana pamusoro pemhangura dhizaini ukobvu uye mhando, kusangana neyakaomesesa yemagetsi uye michina zvinodiwa zvezvakasiyana zvigadzirwa.
4. Kushamwaridzana Kwezvakatipoteredza
Kuenzaniswa nemaitiro echinyakare emhangura foil yekubatanidza nzira, iyo DPC maitiro haidi huwandu hwakakura hwemakemikari anokuvadza, zvichiita kuti ive yakanyanya kugarisana neyakavharisa coating solution.
4. Zhenhua Vacuum's Ceramic Substrate Coating Solution
DPC Horizontal Inline Coater, Yakazara Automated PVD Inline Coating System
Equipment Advantages:
Modular Dhizaini: Mutsetse wekugadzira unotora modular dhizaini, ichibvumira kuchinjika kuwedzera kana kudzikiswa kwenzvimbo dzinoshanda sezvinodiwa.
Kutenderedza Target neDiki-Angle Sputtering: Iyi tekinoroji yakanakira kuisa matete firimu akaturikidzana mukati memakomba madiki-diamita, kuve nechokwadi chekufanana uye mhando.
Seamless Kubatanidzwa neRobhoti: Iyo sisitimu inogona kubatanidzwa zvisina musono nemaoko erobhoti, ichigonesa kuenderera uye yakagadzikana mutsara mutsara mashandiro ane yakakwira otomatiki.
Intelligent Kudzora uye Monitoring System: Yakashongedzerwa nehungwaru kutonga uye yekutarisa sisitimu, inopa yakazara kuona kwezvikamu uye data rekugadzira, kuve nechokwadi chemhando uye kushanda nesimba.
Application Scope:
Inokwanisa kuisa zvakasiyana-siyana zvekutanga simbi mafirimu, akadai Ti, Cu, Al, Sn, Cr, Ag, Ni, etc. Mafirimu aya anoshandiswa zvakanyanya mu semiconductor electronic components, kusanganisira ceramic substrates, ceramic capacitors, LED ceramic brackets, nezvimwewo.
