Zida zazikulu za mzere wa SMT ndi ziti?

Dzina lonse la SMT ndiukadaulo wa Surface mount.Zida zotumphukira za SMT zimatanthawuza makina kapena zida zomwe zimagwiritsidwa ntchito popanga ma SMT.Opanga osiyanasiyana amakonza mizere yopangira ma SMT osiyanasiyana malinga ndi mphamvu zawo ndi kukula kwawo komanso zomwe makasitomala amafuna.Atha kugawidwa m'mizere yopangira ma SMT yodziwikiratu komanso mizere yodzipangira yokha ya SMT.Makina ndi zida sizofanana, koma zida zotsatila za SMT ndi mzere wokwanira komanso wolemera.

1.Loading makina: The PCB bolodi aikidwa mu alumali ndi basi kutumizidwa makina suction board.

2.Makina oyamwa: kunyamula PCB ndi kuziyika pa njanji ndi kusamutsa kwa solder phala chosindikizira.

3.Chosindikiza cha solder paste: tsitsani phala la solder molondola kapena patch glue pamapadi a PCB kukonzekera kuyika chigawocho.Makina osindikizira omwe amagwiritsidwa ntchito pa SMT agawidwa pafupifupi mitundu itatu: makina osindikizira amanja, makina osindikizira a semi-automatic ndi makina osindikizira okha.

4.SPI: SPI ndiye chidule cha Solder Paste Inspection.Iwo makamaka ntchito kudziwa khalidwe la matabwa PCB kusindikizidwa ndi osindikiza phala solder, ndi kudziwa makulidwe, flatness ndi malo osindikizira solder phala yosindikiza.

5.Mounter: Gwiritsani ntchito pulogalamu yosinthidwa ndi zida kuti muyike bwino zigawozo pamalo okhazikika a bolodi losindikizidwa.Chokweracho chikhoza kugawidwa kukhala chokwera kwambiri komanso chokwera chamitundu yambiri.Chokwera chothamanga kwambiri nthawi zambiri chimagwiritsidwa ntchito poyika zida zazing'ono za Chip, makina oyika zinthu zambiri komanso opanda pake amakweza zida zazikulu kapena zigawo zogonana ndi amuna kapena akazi okhaokha monga masikono, ma disc kapena machubu.

6.Kusintha kwa PCBr: chipangizo chosinthira matabwa a PCB.

7.Reflow uvuni: Ili kuseri kwa makina oyika mu mzere wopangira SMT, imapereka malo otentha kuti asungunuke phala la solder pa mapepala, kotero kuti zigawo za pamwamba ndi mapepala a PCB zimagwirizanitsidwa mwamphamvu ndi solder phala alloy.

8.Chotsitsa: Basi kusonkhanitsa PCBA kudzera njanji kufala.

9 .AOI: Automatic Optical Identification System, chomwe ndi chidule cha Chingerezi (Auto Optical Inspection), tsopano chimagwiritsidwa ntchito kwambiri poyang'anira mizere ya msonkhano wa board board mumakampani opanga zamagetsi ndikulowa m'malo mwa zowunikira zam'mbuyomu.Pozindikira zokha, makinawo amangoyang'ana PCB kudzera mu kamera, amatolera zithunzi, ndikufanizira zolumikizira zoyesedwa ndi magawo oyenerera pankhokwe.Pambuyo pokonza zithunzi, zolakwika pa PCB zimafufuzidwa, ndipo zolakwikazo zimawonetsedwa / kuzindikiridwa kudzera muwonetsero kuti akonzere Wokonza.
