Chidule
Kachiwiri, cholekanitsa cha SMT chili ndi magwiridwe antchito abwino olekanitsa. Chimatha kusiyanitsa bwino zizindikiro zotumizidwa ndi zolandiridwa, kupewa kusokoneza ndikusunga umphumphu wa Chizindikiro. Kupambana kwa magwiridwe antchito olekanitsawa kungatsimikizire kuti dongosololi likugwira ntchito bwino ndikuchepetsa kusokoneza kwa zizindikiro.
Kuphatikiza apo, chotchingira kutentha cha SMT chilinso ndi kukhazikika kwabwino kwa kutentha. Chimatha kugwira ntchito pa kutentha kwakukulu, nthawi zambiri kufika kutentha kuyambira -40℃ mpaka +85℃, kapena kupitirira apo. Kukhazikika kwa kutentha kumeneku kumathandiza chotchingira kutentha cha SMT kugwira ntchito modalirika m'malo osiyanasiyana.
Njira yopangira ma SMT isolators imathandizanso kuti zikhale zosavuta kuziphatikiza ndikuziyika. Amatha kuyika mwachindunji zida zodzipatula pa ma PCB kudzera muukadaulo woyika, popanda kufunikira njira zachikhalidwe zoyika ma pini kapena njira zosokera. Njira yopangira ma pini pamwamba pa chinthuchi sikuti imangowonjezera magwiridwe antchito, komanso imalola kuphatikiza kwakukulu, motero kusunga malo ndikupangitsa kuti kapangidwe kake kakhale kosavuta.
Kuphatikiza apo, ma SMD isolators amagwiritsidwa ntchito kwambiri mu makina olumikizirana a pafupipafupi komanso zida zama microwave. Angagwiritsidwe ntchito kupatula zizindikiro pakati pa ma RF amplifiers ndi ma antenna, zomwe zimapangitsa kuti makina azigwira ntchito bwino komanso kukhazikika. Kuphatikiza apo, ma SMD isolators angagwiritsidwenso ntchito muzipangizo zopanda zingwe, monga kulumikizana opanda zingwe, machitidwe a radar, ndi kulumikizana kwa satellite, kuti akwaniritse zosowa za kudzipatula kwa ma signal a pafupipafupi komanso kusweka.
Mwachidule, chipangizo chodzipatula cha SMD ndi chipangizo chocheperako, chopepuka, komanso chosavuta kuyika chodzipatula chomwe chili ndi bandeji yolumikizirana pafupipafupi, magwiridwe antchito abwino odzipatula, komanso kukhazikika kwa kutentha. Chili ndi ntchito zofunika kwambiri m'magawo monga machitidwe olumikizirana pafupipafupi, zida zama microwave, ndi zida zama wailesi. Ndi chitukuko chopitilira chaukadaulo, zida zodzipatula za SMD zidzachita gawo lofunikira m'magawo ambiri ndikuthandizira pakukula kwa ukadaulo wamakono wolumikizirana.
