Kusiyana 3240 epoxy bolodi ndi fr4 epoxy board

1. Zida zazikulu za fr4 epoxy board zimatumizidwa kunja kwa prepreg. Mitundu yake ndi yoyera, yachikasu ndi yobiriwira. Imakhalabe ndi mphamvu zamakina apamwamba pa kutentha kwa 150 ℃. Imakhala ndi ntchito yabwino yamagetsi pamalo owuma ndi amvula, osawotcha moto, ndipo imagwiritsidwa ntchito pazinthu zamagetsi ndi zamagetsi. Magawo a insulation m’mafakitale ena amapangidwa mosamala ndi zopangira zotumizidwa kunja, makina osindikizira apanyumba ndi njira zokhazikika;

Gulu la fr4 epoxy lili ndi magwiridwe antchito okhazikika amagetsi, kusalala bwino, malo osalala, opanda maenje, komanso kulekerera makulidwe. Ndioyenera kuzinthu zomwe zimakhala ndi zofunikira zogwiritsira ntchito kwambiri zamagetsi zamagetsi, monga matabwa owonjezera a FPC, mapepala obowola a PCB, ndi ma mesons a galasi. , Potentiometer mpweya filimu kusindikizidwa galasi CHIKWANGWANI bolodi, mwatsatanetsatane nyenyezi giya (wopyapyala akupera), mwatsatanetsatane mbale mayeso, magetsi (magetsi) zipangizo kutchinjiriza kukhala spacer, kutchinjiriza akuthandizira mbale, thiransifoma kutchinjiriza mbale, kutchinjiriza galimoto, giya akupera, magetsi chosinthira Insulation bolodi, etc. .

2. 3240 epoxy bolodi Nthawi zambiri amatchedwa 3240 epoxy phenolic glass cloth laminate. Zimapangidwa ndi nsalu yagalasi yamagetsi yomwe imayikidwa ndi epoxy resin, zouma komanso zotentha. Ma epoxy resins nthawi zambiri amatanthauza mankhwala a polima okhala ndi magulu awiri kapena angapo a epoxy mu molekyulu. Kupatulapo ochepa, mamolekyu awo ochulukirapo sakhala okwera.

Mapangidwe a maselo a epoxy resin amadziwika ndi gulu logwira ntchito la epoxy mu unyolo wa maselo. Gulu la epoxy likhoza kupezeka kumapeto, pakati kapena mumayendedwe ozungulira a unyolo wa maselo. Makina ochiritsira a epoxy resin ndi zida zabwino zotetezera zomwe zimakhala ndi dielectric zambiri, kukana kutayikira pamwamba, komanso kukana kwa arc.

3240 epoxy board imagwiritsidwa ntchito kwambiri pamakina, zamagetsi ndi zamagetsi. Ndizoyenera kumakina, zamagetsi, zamagetsi, zamagetsi ndi zina. Amagwiritsidwanso ntchito pokonza zida zoteteza komanso kusinthidwa kukhala magawo osiyanasiyana oteteza. Zida zotetezera zigawo zamagulu.
