Pcb core pcb ama mcpcb
PCB-ga birta (MCPCB) waxaa loo yaqaan PCB-ga birta PCB ama PCB-ga kuleylka. Noocan ah PCB-ga noocan ah wuxuu adeegsadaa shay bir ah halkii uu ka isticmaali lahaa caadiga ah fr4 saldhiga, saldhiga kuleylka ee guddiga.
As waa la yaqaanKuleylka waxaa laga soo saaray guddiga sababta qaar ka mid ah qaybaha elektiroonigga ah inta lagu gudajiro hawlgalka. Birta birta ayaa ku wareejisaa kuleylka guddiga wareega oo ka leexiso udub dhexaadka birta ama kuleylka birta ah ee kululaynta iyo sheyga keydka furaha.
PCB-yada badan ee PCB-ga badan waxaad ka heli doontaa tiro labisan oo lakab ah oo lagu kala qaybiyo dhinaca birta ee birta. Tusaale ahaan, haddii aad eegto 12-lakab PCB, waxaad ka heli doontaa lix lakab oo dusha sare ah iyo lix lakab oo hoose, dhexda waa xudunta birta.
MCPCB ama PCB Core PCB-ga ayaa sidoo kale loo yaqaan ICPB ama PCB birta ah, IMS ama sunta birta ee birta ah, PCBS Clad Clad iyo PCBS Clad.
FAma adiga faham wanaagsan waxaan u isticmaali doonaa uun ereyga PCB-ga birta oo dhan maqaalkan oo dhan.
Qaab-dhismeedka aasaasiga ah ee PCB-ga xulka ah ee birta waxaa ka mid ah waxyaabaha soo socda:
Lakabka naxaasta ah - 1oz.to 6oz. (ugu badan waa 1oz ama 2oz)
Lakabka wareega
Lakabka Dielectric
Maaskaro
Kuleylka kuleylka ama kuleylka kuleylka (lakabka xudunta birta)
Faa'iidada MCPCB
Hormalka kuleylka
CEM3 ama FR4 kuma fiicna qabashada kuleylka. Haddii kulul
Qeybaha loo adeegsaday PCBs waxay leeyihiin fal-gal sabool ah waxayna dhaawici karaan qaybaha ka mid ah golaha PCB. Taasi waa marka PCBs-ka xudunta birta ku soo dhacaya.
MCPCB waxay leedahay wadooyin aad u heer sare ah oo heer sare ah si looga hortago qaybaha ka yimaada burburka.
HCun cun
Waxay bixisaa awood qabow oo aad u fiican. PCB-yada xudunta birta ah waxay ku faafi karaan kuleylka si hufan. Lakabka sicirka sicirka ayaa markaa ku wareejinaya kuleylka kuleylka birta.
JOOJI
Waxay bixisaa xasillooni yar oo ka duwan noocyada kale ee PCBs. Ka dib markii heerkulka laga beddelo 30 digrii Celsius ilaa 140-150 digrii Celsius Celsius, isbedelka cabirka ee xudunta aluminiumka waa 2.5 ~ 3%.
Rku dhaji xeerar
Tan iyo PCBs-ka xudunta biraha ah waxay leeyihiin kulayl wanaagsan oo kuleyl ah iyo wanaajinta kuleylka, waxay u nugul yihiin cilad-gelinta kuleylka awgeed. Sababta oo ah astaamahan ee xudunta birta, PCBs waa doorashada ugu horreysa ee codsiyada sahayda korantada ee u baahan beddelaad sare.
