Pụrụ iche anya kwesịrị ịkwụ ụgwọ polarity ọcha ofụri PCBA usoro, dị ka directional akụrụngwa njehie pụrụ iduga ogbe ihe mberede na ọdịda nke dum PCBA osisi.Ya mere, ọ dị oke mkpa maka ndị injinia na ndị nrụpụta ka ha ghọta ihe SMT polarity.
I. Nkọwa nke polarity
Polarity na-ezo aka na okporo osisi ndị dị mma na ndị na-adịghị mma ma ọ bụ ntụtụ mbụ nke components dị n'otu ụzọ ahụ na nke PCB(bọọdụ sekit e biri ebi).Ọ bụrụ na ntụziaka nke components na PCB adabaghị, a na-akpọ ya azụ azụ.
II.Usoro njirimara polarity
1. resistor nke mgbawa ụdị bụ enweghị polarity
2. Capacitor (Capacitor)
2.1 seramiiki capacitors abụghị polar
2.2 Tantalum capacitors bụ polar.PCB osisi na ngwaọrụ mma pole labeling :1) Ribbon labeling;2) Kaa akara "+";3) Akara akara.
2.3 Aluminom electrolytic capacitor nwere polarity.Ntube akụkụ: agba agba na-anọchi anya adịghị mma;PCB akara: rịbọn ma ọ bụ "+" na-anọchite anya ogwe dị mma.
3. Inductor
3.1 Enweghị polarity chọrọ maka ngwugwu ngwụcha ịgbado ọkụ abụọ dị ka eriri mgbawa.
3.2 Multi-pin inductors nwere ihe chọrọ polarity.Nkebi nke akara: ntụpọ/" 1" na-anọchi anya polarity point;Kaa akara na PCB: Ntụpọ/okirikiri/"*" na-egosi polarity.
4. Light Emitting Diode
4.1 Ihe mmado tebụl SMT LED nwere polarity.Akụkụ na-adịghị mma akara: akwụkwọ ndụ akwụkwọ ndụ adịghị mma;PCB ihe nrịbama na-adịghị mma: 1) mmanya kwụ ọtọ, 2) rịbọn, 3) ihuenyo silk dị nkọ;4) Mbipụta ihuenyo bụ "iche" igbe nnọchiteanya.
5. Diode (9W)
5.1 The diode nwere SMT table mado nwere polarity.Akụkụ na-adịghị mma: 1) rịbọn, 2) uzo, 3) akara agba (vitreous);PCB ime ụlọ imeziwanye ihe:1) mmanya kwụ ọtọ, 2) rịbọn, 3) mpi obibi akwụkwọ, 4) igbe “Modernizing”.
