Yiziphi izinto zokusebenza nemisebenzi edingekayo ekukhiqizeni kwe-PCBA?

Ukukhiqizwa kwe-PCBA kudinga imishini eyisisekelo njengeIphrinta yokunamathisela yokunamathisela ye-SMT, Umshini we-SMT, geleza kabushaihhavini, I-AOIumshini, umshini wokugunda iphinikhodi, i-wave soldering, isithando somlilo sikathayela, umshini wokuwasha amapuleti, ukulungiswa kwe-ICT test, i-FCT test fixture, indawo yokuhlola ukuguga, njll. Izitshalo zokucubungula ze-PCBA ezinosayizi abahlukene zifakwe imishini ehlukene.

1.SMT umshini wokunyathelisa

Umshini wokuphrinta wesimanje wokunamathisela we-solder ngokuvamile uhlanganiswa nokufaka ipuleti, ukunamathisela kwe-solder, ukufaka embossing, ukuhanjiswa kwebhodi lesifunda nokunye.Umgomo wayo wokusebenza uthi: okokuqala, ibhodi lesifunda eliphrintiwe libekwe etafuleni lokumisa indawo, bese kuthi ama-scrapers angakwesokunxele nakwesokudla omshini wokunyathelisa adlulisele i-solder paste noma i-glue ebomvu epuleti le-solder elihambisanayo ngokusebenzisa insimbi yensimbi, bese I-PCB enokuphrinta okufanayo ifakwa emshinini we-SMT ngetafula lokudlulisela le-SMT ezenzakalelayo.

2.Umshini wokubeka

I-SMT: eyaziwa nangokuthi "I-Surface Mount System", emgqeni wokukhiqiza, ilungiswa ngemuva komshini wokuphrinta we-solder unama, iyithuluzi ngokuhambisa ikhanda le-SMT ukuze libeke izingxenye ze-SMT ngokunembile ku-PCB solder plate.Ihlukaniswe yaba i-manual kanye ne-othomathikhi.

3.Reflow welding

Ukugeleza kabusha kuqukethe isekethe yokushisisa eshisisa umoya noma i-nitrogen ezingeni lokushisa eliphezulu ngokwanele ukuze livuthele ebhodini lesifunda esivele linamathiselwe engxenyeni, okuvumela i-solder nhlangothi zombili ukuthi incibilike futhi ihlangane nebhodi lomama.Izinzuzo zale nqubo ukuthi izinga lokushisa lilawulwa kalula, i-oxidation igwenywa ngesikhathi sokushisela, futhi izindleko zokukhiqiza zilawulwa kalula.

4.AOI umtshina

Igama eligcwele le-AOI (I-Automatic Optic Inspection) i-Automatic Optical Inspection, okuyisisetshenziswa esithola izinkinga ezivamile okuhlangatshezwana nazo ekukhiqizweni kokushisela ngokusekelwe ezimisweni zokubona.I-AOI iwubuchwepheshe obusha bokuhlola obusafufusa, kodwa ukuthuthukiswa kuyashesha, abakhiqizi abaningi bethule imishini yokuhlola ye-AOI.Ngesikhathi sokutholwa okuzenzakalelayo, umshini uzoskena i-PCB ngokuzenzakalelayo ngekhamera, uqoqe isithombe, uqhathanise amajoyinti ahloliwe we-solder namapharamitha afanelekile ku-database, futhi uhlole amaphutha ku-PCB ngemuva kokucubungula isithombe, bese ubonisa/umaka amaphutha ngesibonisi noma uphawu oluzenzakalelayo lwabasebenzi abalungisayo.

5. Iphinikhodi yokusika umshini wezingxenye

Isetshenziselwa ukusika kanye nokuguqulwa kwezingxenye zephini.

6. I-Wave soldering

I-Wave soldering ukuvumela indawo yokushisela yepuleti le-plug-in ukuthi ithinte ngqo ithayela eliwuketshezi lokushisa eliphezulu ukuze kufezwe injongo yokushisela, izinga lokushisa eliphakeme likathayela we-liquid ukugcina indawo ethambekele, futhi ngomshini okhethekile wokwenza ithini eliwuketshezi into efanayo ye-wave, ebizwa ngokuthi "i-wave soldering", into yayo eyinhloko i-solder bar.

7. Isitofu sikathayela

Ngokuvamile, isithando somlilo se-tin sibhekisela ekusetshenzisweni kwe-electronic welding ethuluzi lokushisela.Ukuze uthole izingxenye ezihlukene zebhodi lebhodi lokushisela ukungaguquguquki, ukusebenza okulula, okusheshayo, ukusebenza kahle okuphezulu, kungumsizi wakho omuhle ekukhiqizeni nasekucubunguleni.

8. Umshini wokuwasha

Isetshenziselwa ukuhlanza Ibhodi le-PCBA futhi isuse izinsalela zebhodi ngemuva kokushisela.

9. I-ICT test fixture

I-ICT Test isetshenziswa kakhulu Ukuhlola isifunda esivulekile, isifunda esifushane kanye nokushisela zonke izingxenye ze-PCBA ngokuthinta amaphuzu okuhlola wesakhiwo se-PCB.

10. Ukuhlolwa kwe-FCT

I-FCT isho indlela yokuhlola ehlinzeka ngendawo yokusebenza efanisiwe (injabulo nomthwalo) ye-UUT: Iyunithi Engaphansi Kokuhlolwa, eyivumela ukuthi isebenze ezimeni zedizayini ezihlukahlukene, ukuze ithole amapharamitha wesifunda ngasinye ukuze kuqinisekiswe umsebenzi we-UUT.Kalula nje, kusho ukuthi i-UUT ilayisha isasasa elifanele futhi ikala ukuthi impendulo yokuphumayo iyahlangabezana yini nezidingo.

11. Isitendi sokuhlola ukuguga

Indawo yokuhlola ukuguga ingavivinya ibhodi le-PCBA ngamaqoqo.Ibhodi le-PCBA elinezinkinga lingahlolwa ngokulingisa ukusebenza komsebenzisi isikhathi eside.
