Izinhlobo ezahlukahlukene zokupakishwa kwama-SMD

Ngokwendlela yokuhlanganisa, izingxenye ze-elekthronikhi zingahlukaniswa zibe izingxenye ze- through-hole kanye ne-surface Mount components (SMC).Kodwa embonini,I-Surface Mount Devices (SMDs) isetshenziswa kakhulu ukuchaza lokhu phezuluingxenye okuyikhona esetshenziswa kuma-electronics agxunyekwe ngokuqondile phezu kwebhodi lesekethe eliphrintiwe (PCB).Ama-SMD eza ngezitayela zokupakisha ezahlukahlukene, ngayinye yakhelwe izinjongo ezithile, izithiyo zesikhala, kanye nezidingo zokukhiqiza.Nazi ezinye izinhlobo ezijwayelekile zokupakishwa kwe-SMD:

1. Amaphakheji we-SMD Chip (Rectangular):

I-SOIC (Isekhethi Ehlanganisiwe Yohlaka Oluncane): Iphakheji elingunxande elinamaphiko e-gull ezinhlangothini ezimbili, elifanele amasekhethi ahlanganisiwe.

I-SSO (Nciphisa Iphakheji Yohlaka Oluncane): Ifana ne-SOIC kodwa enosayizi womzimba omncane kanye nephimbo elicolekileyo.

I-TSSOP (Iphakheji Yohlaka Oluncane Lwe-Shrink Encane): Inguqulo encane ye-SSO.

I-QFP (Iphakheji Le-Quad Flat): Iphakheji eliyisikwele noma elingunxande elinomkhondo kuzo zonke izinhlangothi ezine.Kungaba iphrofayili ephansi (LQFP) noma iphimbo elihle kakhulu (VQFP).

I-LGA (Land Grid Array): Awekho amahola;esikhundleni salokho, amaphedi okuxhumana ahlelwa ngegridi endaweni engaphansi.

2. Amaphakheji e-SMD Chip (Isikwele):

I-CSP (Iphakheji Yesikali Se-Chip): Ihlangene kakhulu namabhola e-solder ngqo emaphethelweni engxenye.Idizayinelwe ukuthi isondele kusayizi we-chip yangempela.

I-BGA (I-Ball Grid Array): Amabhola e-Solder ahlelwe kugridi ngaphansi kwephakeji, ahlinzeka ngokusebenza okuhle kakhulu kokushisayo nogesi.

I-FBGA (I-Fine-Pitch BGA): Ifana ne-BGA kodwa enephimbo elicolekileyo lokuminyana kwengxenye ephezulu.

3. Amaphakheji we-SMD Diode kanye ne-Transistor:

I-SOT (I-Small Outline Transistor): Iphakheji elincane lama-diode, ama-transistors, nezinye izingxenye ezincane ezihlukene.

I-SOD (I-Outline Diode Encane): Ifana ne-SOT kodwa ikakhulukazi ama-diode.

YENZA (Uhlaka lweDiode):  Amaphakheji amancane ahlukahlukene ama-diode nezinye izingxenye ezincane.

4.Amaphakheji we-SMD Capacitor kanye ne-Resistor:

0201, 0402, 0603, 0805, njll.: Lawa amakhodi ezinombolo amelela ubukhulu bengxenye engxenyeni yeshumi yemilimitha.Isibonelo, okuthi 0603 isho ingxenye enokulinganisa amayintshi angu-0.06 x 0.03 (1.6 x 0.8 mm).

5. Amanye amaphakheji we-SMD:

I-PLCC (I-Plastic Leaded Chip Carrier): Iphakheji eliyisikwele noma elingunxande elinomkhondo kuzo zonke izinhlangothi ezine, lilungele ama-IC nezinye izingxenye.

TO252, TO263, njll.: Lezi izinguqulo ze-SMD zamaphakheji engxenye yembobo evamile afana ne-TO-220, TO-263, anephansi eliyisicaba lokukhwezwa kwendawo.

Ngayinye yalezi zinhlobo zephakeji inezinzuzo zayo kanye nokubi ngokwesayizi, ukuhlangana kalula, ukusebenza okushisayo, izici zikagesi, nezindleko.Ukukhethwa kwephakheji ye-SMD kuncike ezintweni ezifana nomsebenzi wengxenye, indawo yebhodi etholakalayo, amandla okukhiqiza, kanye nezidingo ezishisayo.
