Karolo ea 1 Mekhoa e tloaelehileng ea BOITSEBISO ba likarolo tsa polar tsa SMT

Tlhokomelo e khethehileng e lokela ho lefshoa ho likarolo tsa polarity ho pholletsa le ts'ebetso ea PCBA, kaha liphoso tsa karolo ea tataiso li ka lebisa ho likotsi tsa batch le ho hlōleha ha boto eohle ea PCBA.Ka hona, ho bohlokoa haholo hore basebetsi ba boenjiniere le ba tlhahiso ba utloisise likarolo tsa polarity tsa SMT.

I. Tlhaloso ea polarity
Polarity e bolela hore lipalo tse ntle le tse mpe kapa lithapo tsa pele tsa likarolo li ka lehlakoreng le le leng le la PCB(boto ea potoloho e hatisitsoeng).Haeba tataiso ea likarolo le PCB e sa lumellane, e bitsoa reverse e mpe.

II.Mokhoa oa ho khetholla polarity
1. Mohanyetsi oa mofuta oa chip ha o na polarity

2. Capacitor (Capacitor)

2.1 Ceramic capacitor ha e na polar

2.2 Li-capacitor tsa Tantalum li polar.PCB board le device positive pole labeling :1) Ribbon labeling;2) Tšoaea "+";3) Ho tšoaea bevel.

2.3 Aluminium electrolytic capacitor e na le polarity.Karolo ea ho ngolla: sehlopha sa mebala se emela hampe;PCB e tšoaea: Ribone kapa "+" e emetse palo e ntle.

3. Inductor

3.1 Ha ho na tlhoko ea polarity bakeng sa liphutheloana tse peli tsa welding tse kang chip coil.

3.2 Li-inductors tse ngata-ngata li na le litlhoko tsa polarity.Karolo ea ho tšoaea: letheba/” 1 “e emetse polarity point;Tšoaea ho PCB: Letheba/circle/” * “e bontša polarity.

4. Light Emitting Diode

4.1 Setikara sa tafole sa SMT LED e na le polarity.Karolo e mpe: botala bo bobe;PCB negative marker :1) thipa bar, 2) ribone, 3) silika skrine sharp Angle;4) Khatiso ea skrine ke moemeli oa lebokose "o ikhethang".

5. Diode (9W)
5.1 Diode e nang le pente ea tafole ea SMT e na le polarity.Karolo e mpe ea marker :1) ribone, 2) groove, 3) color marker (vitreous);PCB modernizing room :1) thipa bar, 2) ribone, 3) screen printing horn, 4) "Modernizing" lebokose.

NeoDen e fana ka tharollo ea mohala oa kopano ea SMT e felletseng, ho kenyeletsoa onto ea SMT reflow, mochini o hlabollang, mochini o khethang le oa ho beha, mochini oa khatiso oa solder, Oven ea Reflow, PCB loader, PCB unloader, chip mounter, mochini oa SMT AOI, mochini oa SMT SPI, SMT X- Mochini oa Ray, lisebelisoa tsa mohala oa kopano ea SMT, lisebelisoa tsa tlhahiso ea PCB Lisebelisoa tsa SMT, joalo-joalo mochini ofe kapa ofe oa SMT oo u ka o hlokang, ka kopo ikopanye le rona bakeng sa tlhaiso-leseling e batsi:
