Zeziphi izicelo zeebhodi ze-FR4 PCB?

FR4 PCB ibhodiyeyona PCB ixhaphakileyo, idla ngokufumaneka kwizixhobo zombane ezininzi.Iibhodi ze-PCB ze-FR4 zenziwe nge-fiberglass kunye ne-epoxy zidityaniswe ne-laminated copper cladding.Ezinye zezicelo eziphambili zeebhodi ze-FR4 PCB zezi: IiKhadi zeMizobo yeKhompyutha, ii-Motherboards, iiBhodi zeMicroprocessor, ii-FPGAs, ii-CPLDs, ii-Hard Disk Drives, ii-RF LNAs, i-Satellite Communication Antenna Feeds, i-Switch Mode Power Supplies, ii-Android Phones, kunye nezinye ezininzi.

Ngophuhliso olukhawulezayo lweshishini le-PCB, iibhodi ze-FR4 PCB zidlala indima ebalulekileyo kwizixhobo zonyango, izixhobo zoshishino, izibane, iimoto kunye nemizi-mveliso ye-aerospace.Loluphi usetyenziso oluthile lweebhodi ze-FR4 PCB?

Ukusetyenziswa kwebhodi ye-FR4 PCB kwizixhobo zonyango

Inkqubela phambili ekhawulezileyo yanamhlanje kwisayensi yezonyango inxulumene ngokusondeleyo nophuhliso olukhawulezayo lweshishini le-elektroniki.Izixhobo ezininzi ze-microbial kunye nezinye izixhobo zihlukeneyo ze-FR4 iibhodi ze-PCB, ezifana: imitha ye-pH, inzwa yokubetha kwentliziyo, umlinganiselo wobushushu, umatshini we-EKG, umatshini we-EEG, umatshini we-MRI, i-X-ray, i-CT scan, umatshini woxinzelelo lwegazi, izinga leswekile yegazi Isixhobo sokulinganisa, ii-incubators kunye nezinye izixhobo zonyango.

Ukusetyenziswa kwebhodi ye-FR4 PCB kwizixhobo zoshishino

Iibhodi ze-FR4 PCB zisetyenziswa kakhulu kushishino lokuvelisa, ngakumbi loo mashishini anezixhobo zoomatshini ezinamandla aphezulu, eziqhutywa ziisekethe ezisebenza ngamandla aphezulu kwaye zifuna langoku eliphezulu.Ke ngoko, umaleko wobhedu ongqindilili ulayitiwe kwi-FR4 PCB, eyahlukileyo kubunzimaiiPCBs zombane, kwaye ezi PCBs high-power babe langoku ukuya 100 amps.Oku kubaluleke kakhulu kwizicelo ezifana ne-arc welding, ii-servo motor drives ezinkulu, iitshaja zebhetri ze-lead-asidi, ishishini lomkhosi, kunye noomatshini bomqhaphu wempahla.

Ukusetyenziswa kwebhodi yePCB ekukhanyeni

Sibona izibane ze-LED ezijikelezayo kunye nee-LED eziphezulu, ezi zi-LED ezincinci ezibonelela ngokukhanya okukhanyayo, zifakwe kwi-PCB esekelwe kwi-aluminium.I-Aluminiyam inepropati yokufunxa ubushushu kunye nokubuchitha emoyeni.Ke ngoko, ngenxa yamandla aphezulu, ezi aluminiyamiibhodi PCBzidla ngokusetyenziswa kwiisekethe zesibane se-LED kwiisekethe ze-LED eziphakathi kunye neziphezulu.

Ukusetyenziswa kweebhodi ze-FR4 PCB kwimizi-mveliso yeemoto kunye ne-aerospace

Eyona nto ixhaphakileyo yokuphinda iveliswe ngexesha lokuhamba kweenqwelomoya kunye neemoto zisebenzisa iPCB eguquguqukayo okanye indibaniselwanoPCBs flex eqinileukuhlangabezana nezi vibrations eziphezulu kwaye wenze PCB bhetyebhetye.IiPCB eziguquguqukayo zikhaphukhaphu kodwa ziyakwazi ukumelana nokungcangcazela okuphezulu, okunokunciphisa ubunzima obupheleleyo besiphekepheke ngenxa yobunzima baso.

Nakwindawo emxinwa, iPCB ebhetyebhetye inokulungiswa, nto leyo iluncedo olukhulu ehlala kuyo.Ezi PCB eziguquguqukayo zisetyenziswa njengeziqhagamshelo, ujongano, kwaye zinokudityaniswa nakwizithuba ezixineneyo, ezinje: ngasemva kweephaneli, phantsi kwedeshibhodi, njl.
