PCB waa inay dabka u adkaystaan ​​oo ay gubi kari waayaan heerkul gaar ah, oo keliya in la jilco. Bartilmaameedka heerkulka waqtigan waxaa loo yaqaan heerkulka kala-guurka ee quraaradda (barta TG), oo la xidhiidha xasilloonida tirada PCB.

Waa maxay PCB-ga sare ee TG iyo faa'iidooyinka isticmaalka PCB-ga sare ee TG?

Marka heerkulka kombuyutarka ee TG ee TG uu u kaco waa mid ka mid ah, substrate-ka ayaa ka beddelaya "Dawladaha dhalada" si "gobolka caagga ah", ka dibna heerkulka waqtigan waxaa loo yaqaan heerkulka dareenka (TG) ee guddiga. Si kale haddii loo dhigo, TG waa heerkulka ugu sareeya ee ku-meel-gaarka ah oo sunta ah ay sii adag tahay.

Waa maxay nooca loo yaqaan guddiga PCB gaar ahaan?

Heerka hoose ee hoose ilaa heerka kore ee hoos ku xusan:

94hb - 94Vo - 22F - CEM-1 - CEM-3 - FR-4

Faahfaahinta waa sida soo socota:

94hb: kartoonnada caadiga ah, ee aan wax dabin karin (maaddada fasalka ugu hooseeya, dhinta feeraha, laguma samayn karo korantada guddiga)

94v0: Kaarka kartoonada dib-u-dhigista ee ololka

22F: Fulsamada Glass-dhinac-dhinac ah (u dhinta feeraha)

CEM-1: Golaha Fiblass-ka-hal (qodista kombiyuutarka waa in la sameeyaa, ee aan dhimannin feerka)

Cem-3: Gudiga fiberglass laba-dhinac ah ee guddiga laba-dhinac ah marka laga reebo guddiga laba-dhinac ah, ashyaadan waxaa loo isticmaali karaa gole laba laab, kaasoo ka jaban Fr4)

FR4: Golaha Fiblass laba-dhinac
