Mitundu yosiyanasiyana ya ma SMDs

Malinga ndi njira yochitira msonkhano, zida zamagetsi zitha kugawidwa m'mabowo ndi zida zapamtunda (SMC).Koma mu bizinesi,Zida Zapamwamba Zokwera (SMDs) amagwiritsidwa ntchito mochuluka kufotokoza izi pamwambagawo zomwe zili amagwiritsidwa ntchito pamagetsi omwe amayikidwa mwachindunji pamwamba pa bolodi losindikizidwa (PCB).Ma SMD amabwera m'mapaketi osiyanasiyana, iliyonse yopangidwira zolinga zake, zopinga za malo, komanso zofunikira pakupanga.Nayi mitundu yodziwika bwino yamapaketi a SMD:

1. SMD Chip (Rectangular) Phukusi:

SOIC (Small Outline Integrated Circuit): Phukusi lamakona anayi okhala ndi mapiko a gull-mapiko mbali ziwiri, oyenera mabwalo ophatikizika.

SSOP (Phukusi Lalifupi Laling'ono): Zofanana ndi SOIC koma zocheperako komanso kamvekedwe kakang'ono ka thupi.

TSSOP (Phukusi Laling'ono Laling'ono Laling'ono): Mtundu wocheperako wa SSOP.

QFP (Quad Flat Package): Phukusi lalikulu kapena lamakona anayi okhala ndi zowongolera mbali zonse zinayi.Itha kukhala yotsika kwambiri (LQFP) kapena mawu abwino kwambiri (VQFP).

LGA (Land Grid Array): Palibe zitsogozo;m'malo mwake, mapepala olumikizana amakonzedwa mu gridi pamtunda wapansi.

2. SMD Chip (Square) Phukusi:

CSP (Chip Scale Package): Yophatikizika kwambiri ndi mipira yogulitsira mwachindunji m'mphepete mwa gawolo.Zapangidwa kuti zikhale pafupi ndi kukula kwa chip weniweni.

BGA (Ball Grid Array): Mipira ya solder yokonzedwa mu gululi pansi pa phukusi, kupereka ntchito yabwino kwambiri yotentha ndi magetsi.

FBGA (Fine-Pitch BGA): Yofanana ndi BGA koma yokhala ndi phula labwino kwambiri la kachulukidwe kagawo kapamwamba.

3. Phukusi la SMD Diode ndi Transistor:

SOT (Small Outline Transistor): Phukusi laling'ono la ma diode, ma transistors, ndi tizigawo tating'ono tating'ono.

SOD (Small Outline Diode): Yofanana ndi SOT koma makamaka ya diode.

KUCHITA (Diode Outline):  Phukusi laling'ono la ma diode ndi zigawo zina zazing'ono.

4.SMD Capacitor ndi Resistor Phukusi:

0201, 0402, 0603, 0805, ndi zina zotero.: Awa ndi manambala oimira miyeso ya chigawo chimodzi chakhumi cha millimeter.Mwachitsanzo, 0603 amatanthauza kagawo kakang'ono ka mainchesi 0.06 x 0.03 (1.6 x 0.8 mm).

5. Maphukusi Ena a SMD:

PLCC (Pulasitiki Leaded Chip Carrier): Phukusi la square kapena rectangular lokhala ndi zotsogolera kumbali zonse zinayi, zoyenera ma IC ndi zigawo zina.

TO252, TO263, etc.: Awa ndi mitundu ya SMD yamaphukusi amtundu wapabowo ngati TO-220, TO-263, okhala ndi pansi pamunsi kuti akhazikike pamwamba.

Iliyonse mwa mitundu ya phukusili ili ndi zabwino ndi zovuta zake malinga ndi kukula, kumasuka kwa msonkhano, magwiridwe antchito amafuta, mawonekedwe amagetsi, ndi mtengo wake.Kusankhidwa kwa phukusi la SMD kumadalira zinthu monga ntchito ya gawo, malo omwe alipo, kuthekera kopanga, ndi zofunikira zamafuta.
