Impahla Yomkhiqizo
Njengomphakeli wobuchwepheshe obuhlukahlukene be-PCB, amavolumu, izinketho zesikhathi sokuhola, sinokukhethwa kwezinto ezijwayelekile lapho umkhawulokudonsa omkhulu wezinhlobonhlobo zezinhlobo ze-PCB ungambozwa futhi ohlale utholakala endlini.
Izidingo zezinye noma zezinto ezikhethekile nazo zingahlangatshezwana nazo ezikhathini eziningi, kodwa, kuye ngezidingo eziqondile, kungadingeka kuze kufike ezinsukwini zokusebenza eziyi-10 ukuze kutholwe impahla.
Thintana nathi futhi uxoxe ngezidingo zakho nomunye wabathengisi bethu noma ithimba le-CAM.
Izinto ezijwayelekile ezisesitokweni:

| Prepregs | 0.084mm* | Kuya ngesakhiwo | 1080 |
| Prepregs | 0.112mm* | Kuya ngesakhiwo | 2116 |
| Prepregs | 0.205mm* | Kuya ngesakhiwo | 7628 |
Ugqinsi lwe-Cu lwezendlalelo zangaphakathi: Okujwayelekile – 18µm no-35 µm,
ngesicelo 70 µm, 105µm kanye no-140µm
Uhlobo lwezinto: FR4
Tg: cishe.150°C, 170°C, 180°C
εr ku-1 MHz: ≤5,4 (okujwayelekile: 4,7) Okuningi kuyatholakala ngesicelo
Isitaki
Isitaki sebhodi lesekethe eliphrintiwe isendlalelo esi-4 sinezendlalelo ezi-3 zesendlalelo esisodwa kanye nesendlalelo esiphansi esenza kube izendlalelo ezingu-4 sezizonke.
Zonke lezi zingqimba zisetshenziselwa ukuhambisa amasignali.
Ama-laver amabili okuqala angaphakathi angaphakathi ngaphakathi futhi avame ukusetshenziswa njengamafasitelana kagesi noma ngokuvamile abizwa ngokuthi umzila wamasignali.
Ukukhuluma nje isitaki se-PCB enezingqimba ezi-4 sine-2 ye-single VCC kanye nongqimba lwaphansi.
Amaphuzu abalulekile okuthenga i-pcb
Iningi labathengi befekthri ye-elekthronikhi badidekile mayelana nentengo yama-PCB.ngisho nabanye abantu abanolwazi lweminyaka eminingi ekuthengeni kwe-PCB bangase bangasiqondi ngokugcwele isizathu sangempela.Eqinisweni, intengo ye-PCB yakhiwe izici ezilandelayo:
Okokuqala, amanani ahlukile ngenxa yezinto ezahlukene ezisetshenziswa ku-PCB.
Ukuthatha izendlalelo eziphindwe kabili ze-pcb njengesibonelo, i-laminate iyahlukahluka kusuka ku-FR-4, CEM-3, njll. ngobubanzi obusuka ku-0.2mm kuya ku-3.6mm.Ugqinsi lwethusi luyahlukahluka kusuka ku-0.5Oz kuya ku-6Oz, konke okubangele umehluko omkhulu wamanani.Izintengo ze-inki ze-soldermask nazo zihlukile kuzinto ezijwayelekile zikayinki we-thermosetting kanye nempahla ye-inki eluhlaza eyi-photosensitive.
Okwesibili, amanani ahlukile ngenxa yezinqubo ezahlukene zokukhiqiza.
Izinqubo ezahlukene zokukhiqiza ziholela ezindlekweni ezahlukene.Okufana nebhodi eligqize ngegolide kanye nebhodi elifakwe ngothayela, ukuma kwendlela yokuqondisa nokushaya, ukusetshenziswa kwemigqa yesikrini sikasilika kanye nemigqa yefilimu eyomile kuzokwakha izindleko ezihlukene, okuholela ekuhlukeni kwamanani.
