Gawo 1 Njira zodziwika bwino za IDENTIFICATION za zigawo za polar za SMT

Chisamaliro chapadera chiyenera kuperekedwa kwa zinthu za polarity mu ndondomeko yonse ya PCBA, monga zolakwika zachigawo zingayambitse ngozi za batch ndi kulephera kwa gulu lonse la PCBA.Chifukwa chake, ndikofunikira kwambiri kuti ogwira ntchito zamagetsi ndi opanga amvetsetse zinthu za SMT polarity.

I. Tanthauzo la polarity
Polarity amatanthauza kuti mitengo yabwino ndi yoyipa kapena mapini oyamba a zigawo ali mbali imodzi ndi PCB (bolodi losindikizidwa).Ngati malangizo a zigawo ndi PCB sizikufanana, amatchedwa zoipa m'mbuyo.

II.Njira yozindikiritsa polarity
1. Wotsutsa wa mtundu wa chip alibe polarity

2. Capacitor (Capacitor)

2.1 Ceramic capacitors si polar

2.2 Tantalum capacitor ndi polar.bolodi la PCB ndi chipangizo cholembapo zabwino :1) Kulemba zilembo za riboni;2) Lembani "+";3) Chizindikiro cha bevel.

2.3 Aluminium electrolytic capacitor ili ndi polarity.Kulemba gawo: gulu lamitundu limayimira zoyipa;Chizindikiro cha PCB: Riboni kapena "+" imayimira mtengo wabwino.

3. Inductor

3.1 Palibe polarity yofunikira pamapaketi awiri owotcherera monga chip coil.

3.2 Multi-pin inductors ali ndi zofunikira za polarity.Kuyika gawo: dontho/” 1 “imaimira polarity point;Ikani pa PCB: Dontho/zozungulira/” * “zimasonyeza polarity.

4. Diode yotulutsa kuwala

4.1 Chomata cha tebulo la SMT LED ili ndi polarity.Gawo loyika chizindikiro: chobiriwira ndi choyipa;PCB negative marker :1) vertical bar, 2) riboni, 3) silika chophimba ngodya lakuthwa;4) Kusindikiza kwazenera ndikoyimira bokosi "chosiyana".

5. Diode (9W)
5.1 Diode yokhala ndi tebulo la SMT ili ndi polarity.Gawo lopanda chikhomo :1) riboni, 2) poyambira, 3) chikhomo chamtundu (vitreous);Chipinda chamakono cha PCB: 1) kapamwamba, 2) riboni, 3) nyanga yosindikizira, 4) bokosi la "Modernizing".

NeoDen imapereka mayankho athunthu a mzere wa SMT, kuphatikiza uvuni wa SMT reflow, makina opangira magetsi, makina osankha ndi malo, makina osindikizira a solder, uvuni wa Reflow, PCB loader, PCB unloader, chip mounter, SMT AOI makina, SMT SPI makina, SMT X- Makina a Ray, zida zolumikizirana za SMT, Zida zopangira PCB SMT zida zosinthira, ndi zina zilizonse makina a SMT omwe mungafune, chonde titumizireni kuti mumve zambiri:
