2. Red Oxidation vs. Black Oxidation: Sirrin Tsari Bayan Launuka

2.1 Red Oxidation: Copper's "Armor"

2.2 Black Oxidation: Alloy "Armor"

2.3 Dabarun Kasuwanci Bayan Zaɓin Launi

Ko da yake maɓalli na ayyukan aiki (mannewa da haɓakawa) na ja da baƙar fata oxidation sun bambanta da ƙasa da 10%, kasuwa yana nuna bambanci:

• Janye Oxidized Copper Foil: Lissafi na kashi 60% na kasuwar kasuwa saboda fa'idar tsadarsa mai mahimmanci (12 CNY/m² vs. baki 18 CNY/m²).
• Black Oxidized Copper Foil: Ya mamaye kasuwa mai girma (FPC mai hawa mota, PCBs-milimita-wave) tare da kashi 75% na kasuwa saboda:
  • Rage 15% a cikin hasara mai girma (Df = 0.008 vs. ja oxidation 0.0095 a 10GHz).
  • 30% inganta CAF (Conductive Anodic Filament) juriya.

3. CVEN METAL: "Nano-Level Masters" na Roughening Technology

3.1 Sabbin Fasahar “Gradient Roughening”

Ta hanyar sarrafa matakai uku,CVEN METALyana inganta tsarin saman (duba hoto 2):

1. Nano-Crystalline Seed Layer: Electro-deposition na jan karfe cores 5-10nm a girman, yawa> 1×10¹¹ barbashi/cm².
2. Ci gaban Micron Dendrite: Pulse current controls dendrite orientation (fifi fifikon (110) shugabanci).
3. Fassara Ƙarfafawa: Organic silane hada guda biyu wakili (APTES) shafi inganta hadawan abu da iskar shaka juriya.

3.2 Aiki Wuce Matsayin Masana'antu

3.3 Ƙarshen Amfani da Matrix

• 5G Base Station PCB: Yana amfani da baƙar fata oxidized jan karfe (Ra = 1.5μm) don cimma <0.15dB/cm asarar sakawa a 28GHz.
• Masu Tarar Batir: Ja oxidizedtsare tagulla(ƙarfin ƙarfi 380MPa) yana ba da rayuwar zagayowar> zagayowar 2000 (ma'auni na 1500 na ƙasa).
• FPCs Aerospace: Ƙaƙƙarfan Layer yana jure wa zafin zafin jiki daga -196 ° C zuwa + 200 ° C don hawan keke 100 ba tare da lalata ba.

4. Filin Yakin Nan gaba don Rufewar Tagulla

4.1 Fasaha mai Tsari

Don buƙatun sadarwa na 6G terahertz, ana haɓaka tsarin serrated tare da Ra = 3-5μm:

• Dielectric Constant Stability: An inganta zuwa ΔDk <0.01 (1-100GHz).
• Juriya na thermal: An rage shi da 40% (cimma 15W/m·K).

4.2 Smart Roughening Systems

Haɗin gano hangen nesa na AI + daidaitawar tsari mai ƙarfi:

• Kulawa da Salon Sama na Zamani: Samfurin mitar firam 100 a sakan daya.
• Daidaita Maɗaukakin Maɗaukaki na YanzuMatsakaicin ± 0.5A/dm².

Maganin tagulla ya samo asali daga “tsari na zaɓi” zuwa “yawan ayyuka.” Ta hanyar bidi'a na tsari da kuma matsanancin kulawar inganci,CVEN METALya tura fasahar roughening zuwa daidaitaccen matakin atomic, yana ba da tallafin kayan tushe don haɓaka masana'antar lantarki. A nan gaba, a cikin tseren don mafi wayo, mafi girma mita, da ingantattun fasahohi, duk wanda ya ƙware da "lambar matakin ƙaramar fasaha" na fasahar roughening zai mamaye babban matakin dabarun fasaha.tsare tagullamasana'antu.
