imveliso PCBA kufuna izixhobo ezisisiseko ezifanaSMT soldering umshicileli wokuncamathisela, Umatshini we-SMT, phinda uqukunjelwei-oveni, AOIumatshini, icandelo pin ukucheba umatshini, amaza soldering, iziko inkonkxa, umatshini wokuhlamba ipleyiti, ICT uvavanyo fixture, FCT test fixture, ukuguga test yokubeka, njl PCBA processing izityalo zobukhulu ezahlukeneyo zixhotyiswe izixhobo ezahlukeneyo.
1.SMT umatshini wokushicilela
Umatshini wokuprinta we-solder wanamhlanje uquka ukuxhonywa kwepleyiti, ukudibanisa i-solder, i-embossing, ukuhanjiswa kwebhodi yesekethe njalo njalo.Umgaqo wayo wokusebenza ngulo: okokuqala, ibhodi yesekethe eprintiweyo igxininiswe kwitafile yokubeka indawo, kwaye emva koko i-scrapers yasekhohlo nasekunene yomatshini wokushicilela idlulisela i-solder paste okanye iglu ebomvu kwipleyiti ye-solder ehambelanayo ngokusebenzisa i-mesh yensimbi, kwaye emva koko I-PCB ene-uniform yoshicilelo igalelo kumatshini we-SMT ngetafile yothumelo lwe-SMT oluzenzekelayo.
2.Umatshini wokubeka
I-SMT: ekwabizwa ngokuba yi "Surface Mount System", kumgca wemveliso, iqulunqwe emva komatshini wokushicilela we-solder paste, isixhobo ngokuhambisa intloko ye-SMT ukubeka amacandelo e-SMT ngokuchanekileyo kwi-solder plate ye-PCB.Yahlulwe kwi-manual kunye ne-automatic.
3.Reflow welding
I-reflow iqulethe isiphaluka sokufudumeza esitshisa umoya okanye i-nitrogen kwiqondo lokushisa eliphezulu ngokwaneleyo ukuvuthela kwibhodi yesiphaluka esele ifakwe kwi-component, ivumela i-solder kumacala omabini ukuba inyibilike kwaye idibanise kwi-motherboard.Iinzuzo zale nkqubo kukuba ubushushu bulawulwa ngokulula, i-oxidation iyagwenywa ngexesha le-welding, kwaye iindleko zokuvelisa zilawulwa ngokulula.
4.AOI detector
Igama elipheleleyo le-AOI (i-Automatic Optic Inspection) yi-Automatic optical Inspection, esisixhobo esibona iziphene eziqhelekileyo ezifunyenwe kwimveliso ye-welding ngokusekelwe kwimigaqo ye-optical.I-AOI yitekhnoloji entsha yovavanyo olusakhulayo, kodwa uphuhliso lukhawuleza, abavelisi abaninzi baqalise izixhobo zovavanyo ze-AOI.Ngexesha lokubhaqa okuzenzekelayo, umatshini uya kuskena i-PCB ngokuzenzekelayo ngekhamera, uqokelele umfanekiso, uthelekise amakhonkco e-solder avavanyiweyo kunye neeparamitha ezifanelekileyo kwisiseko sedatha, kwaye ujonge iziphene kwi-PCB emva kokulungiswa komfanekiso, kwaye ubonise / uphawule iziphene ngomboniso okanye uphawu oluzenzekelayo lwabasebenzi bokulungisa.
5. Iphini lokusika umatshini wamacandelo
Isetyenziselwa ukusika kunye nokuguqulwa kwamacandelo e-pin.
6. I-wave soldering
I-wave soldering kukuvumela umphezulu we-welding yeplagi-in ipleyiti uqhagamshelane ngokuthe ngqo nobushushu obuphezulu betoti yolwelo ukufezekisa injongo ye-welding, ubushushu bayo obuphezulu betoti yolwelo ukugcina indawo etyekelelekileyo, kunye nesixhobo esikhethekileyo ukwenza inkonkxa engamanzi. into efanayo, ebizwa ngokuba "yi-wave soldering", eyona nto iphambili kuyo yi-solder bar.
7. Isitovu senkcenkce
Ngokubanzi, isithando somlilo sibhekisela ekusebenziseni i-welding ye-elektroniki kwisixhobo sokudibanisa.Kwizinto ezidityanisiweyo zebhodi yesekethe ye-welding consistency, kulula ukuyisebenzisa, ngokukhawuleza, ukusebenza kakuhle okuphezulu, ngumncedi wakho olungileyo kwimveliso kunye nokusetyenzwa.
8. Umatshini wokuhlamba
Isetyenziselwa ukucoca ibhodi ye-PCBA kwaye isuse intsalela yebhodi emva kwe-welding.
9. Uvavanyo lwe-ICT
Uvavanyo lwe-ICT lusetyenziswa ikakhulu uVavanyo lwesekethe evulekileyo, isiphaluka esifutshane kunye ne-welding yazo zonke iindawo ze-PCBA ngokuqhagamshelana namanqaku ovavanyo lwe-PCB
10. Uvavanyo lwe-FCT
I-FCT ibhekisa kwindlela yoVavanyo ebonelela ngobume bokusebenza obufanisiweyo (uchulumanco kunye nomthwalo) kwi-UUT: Iyunithi ephantsi koVavanyo, iyenza isebenze kwiindawo ezahlukeneyo zoyilo, ukuze ifumane iiparamitha zelizwe ngalinye ukuqinisekisa umsebenzi we-UUT.Ukubeka nje, kuthetha ukuba i-UUT ilayisha i-excitation efanelekileyo kwaye ilinganisa ukuba impendulo yokuphuma ihlangabezana neemfuno.
11. Uvavanyo lokuguga
I-rack yokuvavanya ukuguga inokuvavanya ibhodi ye-PCBA kwiibhetshi.Ibhodi ye-PCBA eneengxaki zinokuvavanywa ngokufanisa ukusebenza komsebenzisi ixesha elide.
