Ni ibamu si awọn nọmba ti PCB fẹlẹfẹlẹ, o ti wa ni pin si nikan-apa, ni ilopo-apa, ati olona-Layer lọọgan.Awọn ilana igbimọ mẹta ko jẹ kanna.

Ko si ilana Layer ti inu fun ẹgbẹ-ẹyọkan ati awọn panẹli apa meji, ni ipilẹ gige-lilu-tẹle ilana.
Awọn igbimọ Multilayer yoo ni awọn ilana inu

1) Nikan nronu sisan ilana
Ige ati edging → liluho → awọn eya Layer ita → (fifun goolu ni kikun) → etching → ayewo → iboju solder iboju → (ipele afẹfẹ gbona) → awọn ohun kikọ iboju siliki → ṣiṣe apẹrẹ → idanwo → ayewo

2) Sisan ilana ti ilọpo-apa tin spraying ọkọ
Ige eti lilọ → liluho → eru Ejò thickening → lode Layer eya → tin plating, etching tin yiyọ → secondary liluho → ayewo → iboju titẹ sita solder boju → goolu-palara plug → gbona air leveling → siliki screen characters → shape processing → igbeyewo → igbeyewo

3) Double-apa nickel-goolu plating ilana
Ige eti lilọ → liluho → eru bàbà nipọn → lode Layer eya aworan → nickel plating, goolu yiyọ ati etching → secondary liluho → ayewo → siliki iboju solder → siliki iboju ohun kikọ → apẹrẹ apẹrẹ → idanwo → ayewo

4) Sisan ilana ti ọpọ-Layer ọkọ Tinah spraying ọkọ
Ige ati lilọ → liluho aye ihò → akojọpọ Layer eya aworan → akojọpọ Layer etching → ayewo → blackening → lamination → liluho → eru Ejò thickening → lode Layer eya → Tin plating, etching tin Tin yiyọ → Atẹle liluho → ayewo → Silk iboju solder → Gold -plated plug → Ipele afẹfẹ gbigbona → Awọn ohun kikọ iboju Siliki → Ṣiṣe apẹrẹ → Idanwo → Ayewo

5) Sisan ilana ti nickel-goolu plating lori multilayer lọọgan
Ige ati lilọ → liluho aye ihò → akojọpọ Layer eya → akojọpọ Layer etching → ayewo → blackening → lamination → liluho → eru Ejò nipon → lode Layer eya → goolu plating, film yiyọ ati etching → Atẹle liluho → ayewo → iboju titẹ sita solder → awọn kikọ oju iboju → sisẹ apẹrẹ → idanwo → ayewo

6) Sisan ilana ti olona-Layer awo immersion nickel-goolu awo
Ige ati lilọ → liluho aye ihò → akojọpọ Layer eya → akojọpọ Layer etching → ayewo → blackening → lamination → liluho → eru Ejò thickening → lode Layer eya → Tin plating, etching Tin yiyọ → Atẹle liluho → ayewo → Silk iboju solder → Kemikali Immersion Nickel Gold → Awọn ohun kikọ iboju Siliki → Ṣiṣe apẹrẹ → Idanwo → Ayewo.
