Umahluko phakathi kweePCB zeCeramic kunye neePCB ze-FR4 zeMveli
Ngaphambi kokuba sixoxe ngalo mba, masiqale siqonde ukuba zithini ii-PCB zeseramikhi kwaye zithini ii-PCB zeFR4.
Ibhodi yeSekethe yeCeramic ibhekisa kuhlobo lwebhodi yesekethe eyenziwe ngokusekelwe kwizixhobo ze-ceramic, ekwaziwa ngokuba yi-Ceramic PCB (ibhodi yesekethe eprintiweyo). Ngokungafaniyo ne-substrates zeplastiki eziqinisiweyo zeglasi (FR-4), iibhodi zesekethe ze-ceramic zisebenzisa i-substrates ze-ceramic, ezinokubonelela ngozinzo oluphezulu lobushushu, amandla angcono oomatshini, iipropati ze-dielectric ezingcono, kunye nobomi obude. Ii-PCB ze-ceramic zisetyenziswa kakhulu kwi-circuits ezinobushushu obuphezulu, eziphindaphindayo, kunye nezinamandla aphezulu, ezifana nezibane ze-LED, ii-amplifiers zamandla, ii-laser ze-semiconductor, ii-transceivers ze-RF, ii-sensors, kunye nezixhobo ze-microwave.
Ibhodi yeSekethe ibhekisa kwizinto ezisisiseko zezinto ze-elektroniki, ezaziwa ngokuba yi-PCB okanye ibhodi yesekethe eprintiweyo. Yindlela yokuthwala izinto ze-elektroniki ngokuprinta iipateni zesekethe yesinyithi kwiindawo ezingezizo ezokuhambisa umbane, ize emva koko yenze iindlela zokuhambisa umbane ngeenkqubo ezifana nokubola kweekhemikhali, ubhedu lwe-electrolytic, kunye nokubhola.
