Intshayelelo ye-SMD
I-SMT patch ibhekisa kwisifinyezo sothotho lweenkqubo zenkqubo esetyenziwe ngokwesiseko sePCB.I-PCB (iBhodi yeSekethe eprintiweyo) yibhodi yesekethe eprintiweyo.
I-SMT yi-Surface Mount Technology (i-Surface Mount Technology) (isifinyezo se-Surface Mounted Technology), eyona teknoloji idumileyo kunye nenkqubo kwishishini lokuhlanganisa i-electronics.
Itekhnoloji yokuhlangana komphezulu wesekethe ye-elektroniki (i-Surface Mount Technology, i-SMT), eyaziwa ngokuba yi-surface mount okanye iteknoloji yokunyuka komphezulu.Luhlobo lwezixhobo ezingezizo i-pin okanye i-short-lead surface Mount (i-SMC/SMD ngokufutshane, isiTshayina esibizwa ngokuba yi-chip components) ebekwe phezu komphezulu webhodi yesekethe eprintiweyo (iBhodi yeSekethe eShicileleyo, i-PCB) okanye umphezulu wezinye ii-substrates, ngokudityaniswa kweSekethe kunye neteknoloji yoqhagamshelwano ethengiswa kwaye idityaniswe ngeendlela ezifana ne-reflow soldering okanye idiphu i-soldering.
Phantsi kweemeko eziqhelekileyo, iimveliso zombane esizisebenzisayo ziyilwe yi-PCB kunye nee-capacitors ezahlukeneyo, i-resistors kunye namanye amacandelo e-elektroniki ngokwedayagram yesekethe eyiliweyo, ngoko ke zonke iintlobo zezixhobo zombane zifuna iintlobo ngeentlobo ze-SMT chip processing technology ukuze ziqhubeke, umsebenzi wayo ukuvuza solder paste okanye patch iglu kwi pads PCB ukulungiselela i-soldering amacandelo.Izixhobo ezisetyenzisiweyo ngumatshini wokuprinta isikrini (umatshini wokushicilela isikrini), obekwe phambili kumgca wokuvelisa i-SMT.
Inkqubo esisiseko ye-SMT
1. Ushicilelo (ushicilelo lwesilika): Umsebenzi walo kukuprinta i-solder paste okanye ukuncamathisela okuncamathelayo kwiipads zePCB ukulungiselela ukuthengiswa kwamacandelo.Izixhobo ezisetyenzisiweyo ngumatshini wokuprinta isikrini (umatshini wokushicilela isikrini), obekwe phambili kumgca wokuvelisa i-SMT.
2. Ukuhanjiswa kweglue: Kukulahla iglu kwindawo esisigxina yebhodi yePCB, kwaye umsebenzi wayo oyintloko kukulungisa amacandelo kwibhodi yePCB.Izixhobo ezisetyenzisiweyo yi-glue dispenser, ebekwe phambili kumgca wokuvelisa i-SMT okanye emva kwezixhobo zokuvavanya.
3. Ukunyuswa: Umsebenzi wayo kukufaka ngokuchanekileyo amacandelo entaba yomphezulu kwindawo emiselweyo yePCB.Izixhobo ezisetyenzisiweyo ngumatshini wokubeka, okhoyo emva komatshini wokushicilela isikrini kumgca wokuvelisa i-SMT.
4. Ukunyanga: Umsebenzi wayo kukunyibilikisa i-adhesive patch, ukwenzela ukuba amacandelo okuphakama komhlaba kunye nebhodi ye-PCB ihlanganiswe ngokuqinileyo.Izixhobo ezisetyenzisiweyo yi-oven yokunyanga, efumaneka emva komatshini wokubeka kumgca wokuvelisa i-SMT.
5. I-Reflow soldering: Umsebenzi wayo kukunyibilikisa i-solder paste, ukwenzela ukuba i-surface mount components kunye nebhodi ye-PCB ihlanganiswe ngokuqinileyo.Izixhobo ezisetyenzisiweyo yi-oven yokuphinda i-oven / i-soldering wave, ebekwe emva komatshini wokubeka kumgca wokuvelisa i-SMT.
6. Ukucoca: Umsebenzi wayo kukususa iintsalela ze-welding ezinobungozi kumzimba womntu njenge-flux kwibhodi ye-PCB edibeneyo.Isixhobo esisetyenziswayo ngumatshini wokuhlamba, kwaye indawo ayinakulungiswa, kwi-intanethi okanye ngaphandle kwe-intanethi.
7. Ukuhlolwa: Umsebenzi wayo kukuhlola umgangatho we-welding kunye nomgangatho wendibano yebhodi ye-PCB edibeneyo.Izixhobo ezisetyenzisiweyo zibandakanya iglasi yokukhulisa, i-microscope, i-tester ye-intanethi (i-ICT), i-flying probe tester, ukuhlolwa kwe-optical ngokuzenzekelayo (AOI), inkqubo yokuhlola i-X-RAY, umhloli osebenzayo, njl. Indawo inokuqwalaselwa kwindawo efanelekileyo kumgca wokuvelisa. ngokweemfuno zokubhaqwa.
Inkqubo ye-SMT inokuphucula kakhulu ukusebenza kakuhle kwemveliso kunye nokuchaneka kweebhodi zeesekethe eziprintiweyo, kwaye ziqonde ngokwenene ukuzenzekelayo kunye nokuveliswa kobuninzi be-PCBA.
Ukukhetha izixhobo zokuvelisa ezikufanelayo unokufumana isiphumo esiphindwe kabini ngesiqingatha somzamo.I-Chengyuan Industrial Automation ibonelela ngoncedo olulodwa kunye nenkonzo ye-SMT kunye ne-PCBA, kwaye ilungiselela isicwangciso semveliso esifanelekileyo kuwe.
