Chii chinonzi SMT?
SMT, kana kuti tekinoroji yekugadzika pamusoro pechinhu, itekinoroji inoisa zvikamu zvemagetsi zvakananga pamusoro pebhodhi redunhu rakadhindwa (PCB). Nzira iyi iri kuramba ichifarirwa nekuda kwezvakanaka zvayo zvakawanda, zvinosanganisira kugona kushandisa zvikamu zvidiki, kuwana huwandu hwakawanda hwezvikamu, uye kuvandudza kushanda zvakanaka kwekugadzira.
Chii chinonzi SMD?
SMD, kana kuti Surface Mount Device, zvinoreva zvikamu zvemagetsi zvakagadzirirwa kushandiswa neSMT. Zvikamu izvi zvakagadzirirwa kuiswa zvakananga pamusoro pePCB, zvichibvisa kudiwa kwekuiswa kwechinhu chekare.
Mienzaniso yezvikamu zveSMD zvinosanganisira resistors, capacitors, diodes, transistors, uye integrated circuits (ICs). Hukuru hwayo hudiki hunobvumira huwandu hwakawanda hwezvikamu pabhodhi redunhu, zvichikonzera kushanda kwakawanda muchikamu chidiki.
Ndeupi musiyano uripo pakati peSMT neSMD?
Zvakakosha kunzwisisa musiyano uripo pakati pe tekinoroji yekuisa pamusoro (SMT) nemidziyo yekuisa pamusoro (SMD). Kunyangwe zvazvo zvakabatana, zvinosanganisira zvinhu zvakasiyana-siyana zvekugadzira zvemagetsi. Heano mimwe yemisiyano mikuru iripo pakati peSMT neSMD:
Pfupiso
Kunyange zvazvo SMT neSMD dziri pfungwa dzakasiyana, dzine hukama hwakasimba. SMT inoreva maitiro ekugadzira, nepo SMD ichitaura nezvemhando yezvinhu zvinoshandiswa mukuita izvi. Nekubatanidza SMT neSMD, vagadziri vanogona kugadzira zvishandiso zvemagetsi zvidiki, zvidiki zvine simba uye zvine mashandiro akawedzerwa. Iyi tekinoroji yakachinja indasitiri yemagetsi, ichiita kuti mafoni ane mafashoni, makombiyuta anoshanda zvakanyanya uye zvishandiso zvekurapa zvepamusoro zvivepo, pakati pezvimwe zvinhu zvitsva.
