Ibyuma fatizo bikozwe mu muringa hamwe na FR-4 ni bibiri bisanzwe bikoreshwa mu icapiro ry’umuzunguruko (PCB) mu bikoresho bya elegitoroniki. Baratandukanye mubintu bigize ibintu, imikorere iranga hamwe nibisabwa. Uyu munsi, Fastline izaguha isesengura rigereranya ryibi bikoresho byombi uhereye kubuhanga:
Icyuma fatizo cyumuringa cyuzuye isahani: Nibikoresho bishingiye kuri PCB, mubisanzwe ukoresha aluminium cyangwa umuringa nka substrate. Ikintu nyamukuru kiranga ni uburyo bwiza bwo gukwirakwiza ubushyuhe nubushobozi bwo gukwirakwiza ubushyuhe, bityo rero buramenyekana cyane mubisabwa bisaba ubushyuhe bwinshi, nkamatara ya LED hamwe n’amashanyarazi. Substrate yicyuma irashobora kuyobora neza ubushyuhe buturutse ahantu hashyushye PCB kugeza ku kibaho cyose, bityo bikagabanya kongera ubushyuhe no kunoza imikorere yibikoresho.
FR-4: FR-4 ni ibikoresho bya laminate hamwe nigitambara cya fibre fibre nkibikoresho bishimangira hamwe na epoxy resin nkibikoresho. Kugeza ubu ni PCB ikoreshwa cyane, kubera imbaraga zayo za mashini, imiterere yumuriro wamashanyarazi hamwe na flame retardant kandi ikoreshwa cyane mubicuruzwa bitandukanye bya elegitoroniki. FR-4 ifite flame retardant ya UL94 V-0, bivuze ko yaka mumuriro mugihe gito cyane kandi ikwiriye gukoreshwa mubikoresho bya elegitoronike bifite umutekano muke.
itandukaniro nyamukuru ：
Ibikoresho byo gukuramo: Ibyuma bikozwe mu muringa bikoresha ibyuma (nka aluminium cyangwa umuringa) nka substrate, naho FR-4 ikoresha imyenda ya fiberglass na epoxy resin.
Ubushyuhe bwumuriro: Ubushyuhe bwumuriro wurupapuro rwambaye ibyuma birarenze cyane ibya FR-4, bikwiranye nibisabwa bisaba gusohora ubushyuhe bwiza.
Uburemere n'ubunini: Amabati y'umuringa yambaye umuringa ubusanzwe aremereye kurusha FR-4 kandi irashobora kuba yoroshye.
Ubushobozi bwo gutunganya: FR-4 iroroshe gutunganya, ikwiranye nuburyo bugoye bwa PCB; Icyuma cyumuringa cyambaye umuringa kiragoye gutunganya, ariko gikwiranye nuburyo bumwe cyangwa bworoshye.
Igiciro: Igiciro cyurupapuro rwumuringa rwambaye umuringa rusanzwe rusumba FR-4 kubera igiciro cyicyuma kiri hejuru.
Ibisabwa: Ibyuma bikozwe mu muringa bikoreshwa cyane cyane mubikoresho bya elegitoronike bisaba ko ubushyuhe bwiza bugabanuka, nka electronics power na LED. FR-4 irahuze cyane, ikwiranye nibikoresho byinshi bya elegitoroniki hamwe nibishushanyo mbonera bya PCB.
Muri rusange, guhitamo icyuma cyambaye cyangwa FR-4 biterwa ahanini nubuyobozi bukenera ubushyuhe bwibicuruzwa, ibishushanyo mbonera, ingengo yimari nibisabwa byumutekano.
