Zenziwe njani ii-subcates ze-PCB ze-PCB?
Substrate, njengoko igama lisitsho, sisiseko, yinto esisiseko yokuvelisa ibhodi yesekethe eprintiweyo, i-substrate ye-PCB ngokubanzi yenziwe nge-resin, izinto zokuqinisa, izinto eziqhubayo, zininzi iintlobo. I-Resin i-epoxy resin eqhelekileyo, i-phenolic resin, izinto zokuqinisa ezibandakanya iphepha, ilaphu leglasi, njl.
PCB zeendawana izinto eziphathekayo:
Inye, ngokwezinto zokuqinisa:
1. Iphepha eliphantsi (FR-1, FR-2, FR-3);
2.I-epoxy yeglasi yefayibha yengubo (FR-4, FR-5);
3. I-Cm-1, i-CM-3 (ye-Epoxy Material yeBakala le-3);
Iphepha le-4.HDI (Ubuninzi be-Interconnet) (RCC);
I-substrate ekhethekileyo (i-substrate yensimbi, i-substrate ye-ceramic, i-substrate ye-thermoplastic, njl.).
Njani subcates PCB PCB zihlelwe
Jie izizwe ezininzi
Ii. Ngokwentengiselwano yokusebenza kwedangatye:
1. Uhlobo lwethangatye elidangayo (UL94-V0, UL94V1);
2. Uhlobo olungacimiyo lwelangatye (iklasi ye-UL94-HB).
Jie izizwe ezininzi
Zintathu, ngokwe-resin:
1. Ibhodi ye-phenol resin;
2. Ibhodi yentlaka ye-epoxy;
3. Ibhodi yePolyester resin;
4. Ibhodi ye-resin ye-BT;
5. PI ibhodi nentlaka.
