Kodi SMT ndi chiyani?
SMT, kapena ukadaulo woyika zinthu pamwamba, ndi ukadaulo womwe umayika zinthu zamagetsi mwachindunji pamwamba pa bolodi losindikizidwa (PCB). Njira imeneyi ikutchuka kwambiri chifukwa cha zabwino zake zambiri, kuphatikizapo kuthekera kogwiritsa ntchito zinthu zazing'ono, kukwaniritsa kuchuluka kwa zinthu, komanso kukonza magwiridwe antchito opangira zinthu.
Kodi SMD ndi chiyani?
SMD, kapena Surface Mount Device, imatanthauza zigawo zamagetsi zomwe zapangidwira kugwiritsidwa ntchito ndi SMT. Zigawozi zimapangidwa kuti zikhazikike mwachindunji pamwamba pa PCB, kuchotsa kufunikira kokhazikitsa mabowo achikhalidwe.
Zitsanzo za zigawo za SMD zikuphatikizapo zotsutsa, ma capacitor, ma diode, ma transistors, ndi ma circuits ophatikizidwa (ICs). Kukula kwake kochepa kumalola kuchuluka kwa zigawo pa bolodi la circuit, zomwe zimapangitsa kuti ntchito zambiri zikhale zochepa.
Kodi kusiyana pakati pa SMT ndi SMD ndi kotani?
Ndikofunikira kumvetsetsa kusiyana kosiyana pakati pa ukadaulo woyika pamwamba (SMT) ndi zida zoyika pamwamba (SMD). Ngakhale kuti zimagwirizana, zimakhudza mbali zosiyanasiyana za kupanga zamagetsi. Nazi zina mwa kusiyana kwakukulu pakati pa SMT ndi SMD:
Chidule
Ngakhale kuti SMT ndi SMD ndi malingaliro osiyana, ndi ofanana kwambiri. SMT imatanthauza njira yopangira, pomwe SMD imatanthauza mtundu wa zigawo zomwe zimagwiritsidwa ntchito mu ndondomekoyi. Mwa kuphatikiza SMT ndi SMD, opanga amatha kupanga zida zamagetsi zazing'ono komanso zazing'ono zomwe zimagwira ntchito bwino. Ukadaulo uwu wasintha kwambiri makampani a zamagetsi, ndikupanga mafoni apamwamba, makompyuta ogwira ntchito kwambiri komanso zida zamankhwala zapamwamba, pakati pa zinthu zina zatsopano.
Nayi Lembani Njinga Yathu Yosinthira ya SMD:
| Zitsanzo | Kukula()mm） | Voteji Yoyesedwa()V） | Yoyesedwa Pano()mA） | Yavoteredwa()RPM） |
| LD-GS-3200 | 3.4*4.4*4 | 3.0V DC | 85mA Max | 12000±2500 |
| LD-GS-3205 | 3.4*4.4*2.8mm | 2.7V DC | 75mA Max | 14000±3000 |
| LD-GS-3215 | 3*4*3.3mm | 2.7V DC | 90mA Max | 15000±3000 |
| LD-SM-430 | 3.6*4.6*2.8mm | 2.7V DC | 95mA Max | 14000±2500 |
Funsani Akatswiri Anu Atsogoleri
Timakuthandizani kupewa mavuto kuti mupereke khalidwe labwino komanso kuyamikira zosowa zanu za injini yaing'ono yopanda maburashi, panthawi yake komanso pa bajeti.
