Isingeniso SMD
Isiqephu se-SMT sisho isifinyezo sochungechunge lwezinqubo ezicutshungulwa kusisekelo se-PCB.I-PCB (Printed Circuit Board) iyibhodi lesifunda eliphrintiwe.
I-SMT i-Surface Mount Technology (Surface Mount Technology) (isifinyezo se-Surface Mounted Technology), okuwubuchwepheshe nenqubo ethandwa kakhulu embonini yokuhlanganisa izinto zikagesi.
Ubuchwepheshe bokuhlanganisa indawo ye-elekthronikhi (i-Surface Mount Technology, i-SMT), eyaziwa ngokuthi i-surface mount noma ubuchwepheshe bokukhweza phezulu.Kuwuhlobo lwezingxenye zokukhweza ezingeyona iphini noma ezihola kancane (i-SMC/SMD ngamafuphi, amaShayina abizwa ngokuthi izingxenye ze-chip) ezibekwe phezu kwebhodi lesifunda eliphrintiwe (Ibhodi Lesifunda Eliphrintiwe, i-PCB) noma ngaphezulu kwamanye ama-substrates, ngokusebenzisa i-Circuit assembly kanye nobuchwepheshe bokuxhuma obuthengiswa futhi buhlanganiswe ngezindlela ezifana ne-reflow soldering noma i-dip soldering.
Ngaphansi kwezimo ezijwayelekile, imikhiqizo ye-elekthronikhi esiyisebenzisayo iklanywe i-PCB kanye nama-capacitor ahlukahlukene, ama-resistors nezinye izakhi ze-elekthronikhi ngokuya ngomdwebo wesifunda oklanyelwe, ngakho zonke izinhlobo zezinto zikagesi zidinga ubuchwepheshe obuhlukahlukene bokucubungula ama-chip e-SMT ukuze zicutshungulwe, umsebenzi wawo vuza unamathisele we-solder noma namathisela i-glue kumaphedi e-PCB ukuze ulungiselele ukuhlanganiswa kwezinto.Imishini esetshenziswayo ingumshini wokunyathelisa isikrini (umshini wokunyathelisa isikrini), otholakala phambili emgqeni wokukhiqiza we-SMT.
Inqubo eyisisekelo ye-SMT
1. Ukuphrinta (ukuphrinta kukasilika): Umsebenzi wawo ukuphrinta unamathisele okuthengiswayo noma ukunamathisela okunamathelayo kumaphedi e-PCB ukuze kulungiselelwe ukusoda kwezingxenye.Imishini esetshenziswayo ingumshini wokunyathelisa isikrini (umshini wokunyathelisa isikrini), otholakala phambili emgqeni wokukhiqiza we-SMT.
2. Ukukhipha iglue: Kuwukulahla ingcina endaweni engaguquki yebhodi le-PCB, futhi umsebenzi wayo oyinhloko ukulungisa izingxenye ebhodini le-PCB.Imishini esetshenziswayo i-glue dispenser, etholakala ngaphambili komugqa wokukhiqiza we-SMT noma ngemuva kwemishini yokuhlola.
3. Ukukhweza: Umsebenzi wawo ukufaka ngokunembile izingxenye zokukhweza ezingaphezulu endaweni egxilile ye-PCB.Izinto ezisetshenziswayo ziwumshini wokubeka, otholakala ngemuva komshini wokuphrinta isikrini kulayini wokukhiqiza we-SMT.
4. Ukwelapha: Umsebenzi wawo ukuncibilikisa ingcina ye-patch, ukuze izingxenye zokukhweza ezingaphezulu kanye nebhodi le-PCB kuhlanganiswe ngokuqinile ndawonye.Imishini esetshenziswayo iyihhavini elaphayo, etholakala ngemuva komshini wokubeka emugqeni wokukhiqiza we-SMT.
5. I-Reflow soldering: Umsebenzi wayo ukuncibilikisa ukunamathisela kwe-solder, ukuze izingxenye zokukhweza phezulu kanye nebhodi le-PCB kuhlanganiswe ngokuqinile ndawonye.Imishini esetshenziswayo i-reflow oven/wave soldering, etholakala ngemuva komshini wokubeka emugqeni wokukhiqiza we-SMT.
6. Ukuhlanza: Umsebenzi wawo ukususa izinsalela zokushisela eziyingozi emzimbeni womuntu njengokugeleza ebhodini le-PCB elihlanganisiwe.Izinto ezisetshenziswayo ziwumshini wokuwasha, futhi indawo ingase ingalungiseki, ku-inthanethi noma ungaxhunyiwe ku-inthanethi.
7. Ukuhlola: Umsebenzi wayo ukuhlola izinga lokushisela kanye nekhwalithi yokuhlanganisa yebhodi le-PCB elihlangene.Izinto ezisetshenziswayo zihlanganisa ingilazi yokukhulisa, isibonakhulu, isihloli se-inthanethi (i-ICT), isihloli se-flying probe, ukuhlola okuzenzakalelayo (AOI), uhlelo lokuhlola lwe-X-RAY, umhloli osebenzayo, njll. Indawo ingalungiselelwa endaweni efanelekile emugqeni wokukhiqiza. ngokwezidingo zokutholwa.
Inqubo ye-SMT ingathuthukisa kakhulu ukusebenza kahle kokukhiqiza kanye nokunemba kwamabhodi esekethe aphrintiwe, futhi ibone ngempela ukuzenzela nokukhiqizwa ngobuningi kwe-PCBA.
Ukukhetha imishini yokukhiqiza evumelana nawe ngokuvamile ungathola umphumela ophindwe kabili ngesigamu somzamo.I-Chengyuan Industrial Automation inikezela ngosizo lokuma okukodwa kanye nesevisi ye-SMT ne-PCBA, futhi ikuhlelela uhlelo lokukhiqiza olufaneleka kakhulu.
