Iṣakoso ti Ibajẹ Wahala ninu Ilana Lamination fun Ultra-Thin Core (
2025-04-16

Idibajẹ Wahala.png

1.mojuto italaya

Awọn ohun kohun Ultra-tinrin (

  • Ooru wahala: Aiṣedeede CTE ti o ṣẹlẹ nipasẹ awọn iwọn otutu;

  • Wahala darí: Pinpin titẹ ti kii ṣe aṣọ;

  • Wahala ti o ku: Resini shrinkage ati rirọ imularada;

  • Iyọkuro Interlayer: Idiyemeji mismatch ni mojuto / Ejò-Prepreg atọkun.

2.Iṣakoso iwọn otutu

  • Olona-agbegbe ìmúdàgba alapapo:
    Iṣakoso iwọn otutu ti ominira (± 1°C) kọja awọn agbegbe lamination. Fun awọn akopọ Ejò-mojuto-Prepreg, ṣeto iwọn otutu mojuto 5°C ti o ga ju bàbà lati sanpada CTE.

  • Awọn profaili gbigbona Ramped:
    Awọn oṣuwọn gbigbona / itutu agbaiye ≤3°C/min ati ≤2°C/min, lẹsẹsẹ. Iwọn otutu ti o ga julọ ≤Tg+20°C fun awọn ohun elo Tg kekere (fun apẹẹrẹ, FR-4).

3.Imudara titẹ

  • Ikojọpọ titẹ ilọsiwaju:
    0.5 MPa (iṣẹju 5) → 1.5 MPa (iṣẹju 10) → 2.5 MPa (iṣẹju 5).

  • Iṣatunṣe titẹ:
    Awọn paadi silikoni (30-50 Shore A) tabi awọn apẹrẹ graphite lati fi opin si iyatọ titẹ si ± 5%.

4.Imọ-ẹrọ Ohun elo

  • Iyipada ninu CTE:
    Iyatọ CTE Core/Ejò

  • Dada ibere ise:
    O₂/N₂ itọju pilasima (300 W, 60 s) gbe agbara dada soke si 50 mN/m fun ifaramọ to dara julọ.

5.Igbale Lamination ilana

  • Iṣakoso igbale:
    Igbale akọkọ (10-100 mbar) fun yiyọ macro-ofo; igbale giga (

  • Resini sisan isakoso:
    Iposii-iki-kekere (

6.Ilọkuro Wahala

  • Apẹrẹ akopọ Symmetric:
    Ṣe iwọn sisanra Ejò (

  • Lẹhin-curing:
    Itutu agbaiye diẹdiẹ (1°C/min) labẹ 0.5 MPa lati tu igara rirọ silẹ.

7.Real-Time Abojuto

  • FBG sensosi:
    Ti a fi sinu okun Bragg gratings atẹle igara (ipinnu 1 με).

  • Aworan gbona:
    Wa awọn ibi ti o gbona (>5°C iyatọ) fun atunṣe to ni agbara.

  • Lesa profilometry:
    Oju-iwe ogun lẹhin-lamination

8.Awọn Iwadi Ọran

  • Ọran 1: 50μm FR-4 mojuto

    • Profaili: 80°C→140°C→50°C (apapọ iṣẹju 150)

    • Awọn abajade: Oju-iwe ogun dinku lati 0.5 si 0.07 mm / m; peeli agbara>1.0 N/mm.

  • Ọran 2: 75μm PTFE giga-igbohunsafẹfẹ mojuto

    • Ar pilasima ibere ise → 220 ° C lamination @ 1,8 MPa

    • Awọn abajade: Dk iyatọ

9.Awọn itọsọna Innovation

  • Nano-cellulose imuduroIwọn rirọ> 8 GPa lati ṣe idiwọ wrinkling.

  • Lesa dada texturing: Ra = 1 – 2 μm fun idawọle ẹrọ lori awọn ohun kohun Rogers RO3000.

  • AI-ìṣó oni ibeji: Asọtẹlẹ biinu fun awọn iyatọ ilana.
