Ingxenye 1 Izindlela Ezijwayelekile ZOKUKHOMBA kwezingxenye ze-SMT ze-polar

Ukunaka okukhethekile kufanele kukhokhwe ezingxenyeni ze-polarity kuyo yonke inqubo ye-PCBA, njengoba amaphutha engxenye yokuqondisa angaholela ezingozini zenqwaba kanye nokwehluleka kwalo lonke ibhodi le-PCBA.Ngakho-ke, kubaluleke kakhulu kubasebenzi bonjiniyela nabakhiqizi ukuthi baqonde izici ze-SMT polarity.

I. Incazelo ye-polarity
I-polarity isho ukuthi izigxobo ezinhle nezingezinhle noma izikhonkwane zokuqala zezingxenye zisendleleni efanayo nalezo ze-PCB(ibhodi lesekethe eliphrintiwe).Uma isiqondiso sezingxenye kanye ne-PCB kungafani, kubizwa ngokuthi i-reverse embi.

II.Indlela yokuhlonza i-polarity
1. I-Resistor yohlobo lwe-chip ayinayo i-polarity

2. I-Capacitor (I-Capacitor)

2.1 Ama-Ceramic capacitor awawona ama-polar

2.2 I-Tantalum capacitor i-polar.Ibhodi le-PCB nedivayisi ilebula yesigxobo esihle :1) Ukulebula kweribhoni;2) Maka “+”;3) Ukumaka kwe-bevel.

2.3 I-Aluminium electrolytic capacitor ine-polarity.Ukulebula kwengxenye: ibhendi yombala imele negative;Ukumaka kwe-PCB: Iribhoni noma u-“+” umele isigxobo esihle.

3. Inductor

3.1 Ayikho imfuneko ye-polarity yamaphakheji amabili wokushisela njenge-chip coil.

3.2 Ama-multi-pin inductors anezidingo ze-polarity.Ukumakwa kwengxenye: ichashazi/” 1 “imele iphuzu le-polarity;Maka ku-PCB: Ichashazi/umbuthano/” * “ibonisa ukuhlukana phakathi.

4. I-Diode Ekhipha Ukukhanya

4.1 I-LED yesitika setafula le-SMT ine-polarity.Ingxenye umaka onegethivu: okuluhlaza kunegethivu;Umaka we-PCB onegethivu :1) ibha eqondile, 2) iribhoni, 3) I-Engeli ebukhali yesikrini sikasilika;4) Ukuphrinta kwesikrini “kuhlukile” okumelela ibhokisi.

5. I-Diode (9W)
5.1 I-diode enonamathisele ithebula le-SMT ine-polarity.Ingxenye umaka onegethivu :1) iribhoni, 2) inkatho, 3) umaka wombala (vitreous);Igumbi le-PCB lesimanjemanje :1) ibha emile, 2) iribhoni, 3) uphondo lokuphrinta lwesikrini, 4) ibhokisi elithi “Modernizing”.

I-NeoDen ihlinzeka ngezixazululo zomugqa womhlangano we-SMT ogcwele, okuhlanganisa i-oven reflow ye-SMT, umshini wokunamathisela amaza, umshini wokukhetha nendawo, iphrinta yokunamathisela ye-solder, ihhavini ye-Reflow, isilayishi se-PCB, isilayishi se-PCB, isiqhumiso se-chip, umshini we-SMT AOI, umshini we-SMT SPI, i-SMT X- Umshini weRay, okokusebenza komugqa womhlangano we-SMT, Izisetshenziswa zokukhiqiza ze-PCB SMT izingxenye eziyisipele, njll.
