He aha ka SMT?
ʻO SMT, a i ʻole ʻenehana kau ʻana ma luna, he ʻenehana ia e kau pololei ana i nā ʻāpana uila i ka ʻili o kahi papa kaapuni i paʻi ʻia (PCB). Ke lilo nei kēia ʻano hana i mea kaulana ma muli o kona mau pono he nui, me ka hiki ke hoʻohana i nā ʻāpana liʻiliʻi, hoʻokō i ka nui o nā ʻāpana, a hoʻomaikaʻi i ka pono hana.
He aha ka SMD?
ʻO SMD, a i ʻole Surface Mount Device, e pili ana i nā ʻāpana uila i hana kūikawā ʻia no ka hoʻohana ʻana me SMT. Ua hoʻolālā ʻia kēia mau ʻāpana e kau pololei i ka ʻili PCB, e hoʻopau ana i ka pono no ke kau ʻana ma o ka lua kuʻuna.
ʻO nā hiʻohiʻona o nā ʻāpana SMD e komo pū me nā resistors, capacitors, diodes, transistors, a me nā kaapuni hoʻohui ʻia (ICs). ʻO kona nui liʻiliʻi e ʻae ai i ka nui o nā ʻāpana ma ka papa kaapuni, e hopena ana i ka hana hou aku ma kahi kapuaʻi liʻiliʻi.
He aha ka ʻokoʻa ma waena o SMT a me SMD?
He mea nui e hoʻomaopopo i nā ʻokoʻa like ʻole ma waena o ka ʻenehana hoʻopaʻa ʻili (SMT) a me nā mea hoʻopaʻa ʻili (SMD). ʻOiai pili lākou, pili lākou i nā ʻano like ʻole o ka hana ʻana i nā mea uila. Eia kekahi o nā ʻokoʻa koʻikoʻi ma waena o SMT a me SMD:
Hōʻuluʻulu manaʻo
ʻOiai he mau manaʻo like ʻole ʻo SMT a me SMD, pili loa lāua. Pili ʻo SMT i ke kaʻina hana ʻana, ʻoiai ʻo SMD e pili ana i ke ʻano o nā ʻāpana i hoʻohana ʻia i ke kaʻina hana. Ma ka hoʻohui ʻana iā SMT a me SMD, hiki i nā mea hana ke hana i nā mea uila liʻiliʻi a ʻoi aku ka liʻiliʻi me ka hana i hoʻonui ʻia. Ua hoʻololi kēia ʻenehana i ka ʻoihana uila, e hiki ai ke loaʻa nā kelepona akamai, nā kamepiula hana kiʻekiʻe a me nā mea lapaʻau holomua, a me nā hana hou ʻē aʻe.
Eia ka papa inoa o kā mākou SMD Reflow Motor:
| Nā kumu hoʻohālike | Ka nui（mm） | Ka Uila i helu ʻia（V） | Manaʻo ʻia i kēia manawa（mA） | Loiloi ʻia（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 |
E kūkākūkā me kāu poʻe loea alakaʻi
Kōkua mākou iā ʻoe e pale i nā pilikia e hāʻawi i ka maikaʻi a me ka waiwai o kāu pono mīkini micro brushless, i ka manawa kūpono a ma ke kālā kūpono.
