Icyuma shing clap clad clate na fr-4 ni ebyiri zisanzwe zikoreshwa mu ntangiriro zumuzunguruko (PCB) mu ntangiriro za elegitoroniki. Biratandukanye mubintu bifatika, ibiranga imikorere nibisabwa. Uyu munsi, kwiyiriza ubusa bizaguha isesengura igereranya yibi bikoresho byombi uhereye kubitekerezo byumwuga:
Icyuma shing clad clad playe: Nibikoresho bya PCB ishingiye ku ibyuma, mubisanzwe ukoresheje aluminium cyangwa umuringa nka substrate. Ikintu nyamukuru ni imikorere myiza yubushyuhe nubushobozi bwo gutandukana nubushyuhe, birakunzwe cyane mubisabwa bisaba imishinga yubusuku, nka LETA Kumurika no guhindura imbaraga. Intsinzi ibyuma irashobora gukora neza ahantu hashyushye ya PCB ku kibaho cyose, bityo bigabanya ubushyuhe no kunoza imikorere rusange yikikoresho.
Fr-4: Fr-4 ni ikintu cya laminate hamwe nigitambaro cya fibre nkibikoresho bishimangira na epoxy resin nka bunder. Kugeza ubu ni ugukoresha neza PCB, kubera imbaraga zamashanyarazi, imitungo y'amashanyarazi hamwe na Flame Umuti utangaje kandi ukoreshwa cyane mu bicuruzwa bitandukanye bya elegitoroniki. Fr-4 ifite ikirenga cyo gucika intege cya Ul94 v-0, bivuze ko yatwitse umuriro mugihe gito cyane kandi ikwiriye gukoreshwa mubikoresho bya elegitoroniki bifite umutekano mwinshi hamwe nibisabwa byimitekano.
Itandukaniro ryingenzi:
Ibikoresho byongereranyo: Ibyuma by'icyuma bikoresha ibyuma (nka aluminium cyangwa umuringa) nka subper) nka subper, mugihe fr-4 ikoresha umwenda wa fiberglass na epoxy resin.
Imyitwarire yubushyuhe: Imyitwarire yubushyuhe bwinkoni yicyuma irarenze iy'ifaranga rya Fr-4, rikwiranye na Porogaramu isaba gutandukana kwubushyuhe.
Uburemere nubwinshi: Impapuro za clad umuringa mubisanzwe ziremereye kuruta fr-4 kandi zirashobora kuba zinanutse.
Ubushobozi bwo gutunganya: FR-4 biroroshye gutunganya, bikwiye kubishushanyo byinshi bya PCB; Icyuma Clad Clad Coupe biragoye gutunganya, ariko bikwiranye na enterineti imwe cyangwa yoroshye.
Igiciro: Igiciro cyibyuma cya Clad Clad Clad ari hejuru ya fr-4 kubera igiciro cyicyuma cyo hejuru.
Porogaramu: Isahani ya Clad Clad ikoreshwa cyane mubikoresho bya elegitoronike bisaba gutandukana kwubushyuhe, nka elegitoroniki yububasha kandi iyobora itara. FR-4 ni byinshi bihuriye, bikwiranye n'ibikoresho bisanzwe bya elegitoroniki hamwe n'ibishushanyo byinshi bya PCB.
Muri rusange, guhitamo icyuma cyangwa fr-4 biterwa ahanini nubuyobozi bwubushyuhe bukeneye ibicuruzwa, igishushanyo mbonera, ibishushanyo, byije hamwe nibisabwa byingengo yumutekano.
