Vaega 1 Fa'asinomaga masani o vaega SMT polar

E tatau ona gauai faapitoa atu i elemene polarity i le faagasologa atoa o le PCBA, e pei o mea sese vaega faasinoala e mafai ona taitai atu ai i faalavelave faafuasei ma le toilalo o le laupapa PCBA atoa.O le mea lea, e matua taua tele mo le inisinia ma le gaosiga o tagata faigaluega ia malamalama i elemene polarity SMT.

I. Uiga o le polarity
Polarity o loʻo faʻatatau i pou lelei ma le leaga poʻo pine muamua o vaega o loʻo i ai i le itu lava e tasi ma i latou o le PCB (lolomi laupapa laupapa).Afai e le fetaui le itu o vaega ma le PCB, e taʻua o le leaga o le suiga.

II.Metotia e iloagofie ai polarity
1. Resistor o le ituaiga chip e leai se polarity

2. Pusa (Capacitor)

2.1 capacitors sima e le polar

2.2 Tantalum capacitors e polar.laupapa PCB ma masini fa'ailoga pou lelei :1) Fa'ailoga lipine;2) Faailoga “+”;3) Faailoga o le Bevel.

2.3 Aluminum electrolytic capacitor e polarity.Fa'ailoga vaega: o le fusi lanu o lo'o fa'atusalia le leaga;Faailoga PCB: O le lipine poʻo le "+" o loʻo faʻatusalia ai le pou lelei.

3. Inductor

3.1 E leai se polarity manaʻomia mo le lua faʻapipiʻi pito faʻapipiʻi e pei o le chip coil.

3.2 Inductors tele-pine e iai manaʻoga polarity.Faailoga vaega: togi/” 1 “e tu mo le polarity point;Faailoga i luga ole PCB: Dot/circle/” * “faailoa ai le polarity.

4. Malamalama Emitting Diode

4.1 O LE SMT laulau fa'apipi'i LED e polarity.Faailoga le lelei vaega: le lanu meamata e leaga;PCB fa'ailoga leaga:1) pa tūsa'o, 2) lipine, 3) mata siliki Angle ma'ai;4) Lomitusi screen o le sui "tulaga ese" pusa.

5. Diode (9W)
5.1 O le diode ma SMT laulau pa'u e polarity.Faailoga le lelei vaega :1) lipine, 2) togo, 3) maka lanu (vitreous);potu fa'aonaponei PCB: 1) pa tu'u sa'o, 2) lipine, 3) pu fa'asalalau lau, 4) pusa "Modernizing".

NeoDen maua ai se SMT atoa fofo laina, e aofia ai SMT reflow ogaumu, galu soldering masini, piki ma tuu masini, solder faapipii lomitusi, Reflow umu, PCB uta, PCB unloader, chip mounter, SMT AOI masini, SMT SPI masini, SMT X- Ray masini, SMT fa'apotopotoga laina meafaigaluega, PCB gaosiga Meafaigaluega SMT vaega fa'apitoa, ma isi so'o se ituaiga masini SMT e te mana'omia, fa'amolemole fa'afeso'ota'i mai mo nisi fa'amatalaga:
