Pataki ti pilasima Cleaning Ṣaaju ki o to Multilayer Board Lamination

1. abẹlẹ & mojuto Oran

Ninu iṣelọpọ PCB multilayer, awọn ifunmọ lamination awọn ohun kohun inu, prepreg, ati bankanje bàbà labẹ ooru/titẹ. Awọn idoti (awọn epo, oxides, eruku) lori awọn aaye ṣaaju idi lamination:

• Adhesion interfacial alailagbara: Asiwaju si delamination tabi roro;

• Degraded ifihan agbara iyege: Voids ṣe alekun pipadanu dielectric (Df) ati afihan ifihan agbara;

• Igbẹkẹle iwọn otutu-darí: CTE mismatch concentrates wahala, isare rirẹ ikuna.

2. Awọn ọna ẹrọ ti Pilasima Cleaning

Pilasima mimọ nlo gaasi ionized (O₂, N₂, Ar) lati ṣe ipilẹṣẹ awọn eya ifaseyin (awọn elekitironi, ions, radicals) fun:

• Ti ara ninu:

  • Yọ awọn ẹwẹ titobi kuro (

  • Etches dada lati mu roughness (Ra = 0.5-2 μm).

• Kemikali iyipada:

  • Oxidizes organics (fun apẹẹrẹ, O₂ pilasima decomposes awọn epo sinu CO₂/H₂O);

  • Ṣe afihan awọn ẹgbẹ pola (-OH, -COOH), igbega agbara dada (20-30 → 50-70 mN / m).

• Dada ibere ise:

  • Ṣe ilọsiwaju wettability resini fun sisan prepreg to dara julọ.

3. Itupalẹ iwulo

(1) Imudara Interfacial imora

• Data: Peeli agbara pọ lati 0.5 kN / m si 1.2-1.5 kN / m (IPC-TM-650 2.4.8);

• Idinku ikuna: Delamination ewu silė nipa 80% (SEM agbelebu-apakan onínọmbà).

(2) Imudara Dielectric Performance

• Iṣakoso ofo: Agbegbe asan lẹhin-mimọ

• Idinku ifihan agbara: Pipadanu ifibọ n dinku nipasẹ 0.2–0.3 dB/cm @10 GHz.

(3) Iduroṣinṣin ilana

• Ìṣọ̀kan: Ni wiwa eka ẹya (afọju vias, itanran wa);

• Eco-ibamu: Rọpo awọn kẹmika lile (H₂SO₄/H₂O₂), idinku VOC/danu.

4. Awọn Ilana Ilana bọtini

• Gaasi yiyan:

  • O₂: Imukuro Organic ti o munadoko ṣugbọn o le lori-oxidize Ejò;

  • Ar/N ₂ adapo: Etching ti ara fun awọn ohun elo ti o ni imọran;

  • H₂: Din kekere oxides.

• Agbara & akoko:

  • Agbara RF: 300-1000 W (iyẹwu ti o gbẹkẹle);

  • Iye akoko: 30-180 iṣẹju-aaya (iwọntunwọnsi laarin mimọ ati ibajẹ).

• Igbale ipele:

  • Ipilẹ titẹ

5. Iye-anfani & Ifọwọsi Ile-iṣẹ

• Ifiwera iye owo:

  Ọna	CapEx	OpEx	Iṣẹ ṣiṣe
  Pilasima ninu	Ga	Alabọde	Ga
  Kemikali ninu	Kekere	Ga	Alabọde
  Ultrasonic	Alabọde	Alabọde	Kekere

• Awọn ajohunše:

  • IPC-6012 nilo agbara interfacial ≥0.8 kN / m;

  • Automotive (AEC-Q200) ati Aerospace (NASA-STD-8739) ase dada pretreatment.

6. Awọn italaya & Awọn ojutu

• Ipenija 1: Ejò lori-oxidation:

  • Ojutu: Ar / H₂ mix (4: 1) dinku ifoyina;

• Ipenija 2: Aṣọṣọkan-panel nla:

  • Ojutu: Olona-electrode orun tabi conveyorized awọn ọna šiše;

• Ipenija 3: idiyele aimi:

  • Ojutu: Ionizers yomi awọn idiyele lati ṣe idiwọ eruku.
