Ungakhetha kanjani umshini wokusika we-pcb ofanele.

Abakhiqizi abaningi bemikhiqizo ye-elekthronikhi bakhiqiza amabhodi e-PCB, futhi sebeqalile ukukhetha ukusebenzisa abasiki be-pcb ngenxa yezidingo zokwandisa ukukhiqizwa nokuthuthukisa ikhwalithi yomkhiqizo.Kodwa abantu abaningi abazi ukuthi bangakhetha kanjani apcb ibhodi ukusika umshini, ecabanga ukuthi kungakhathaliseki ukuthi yimuphi umshini ongahlukanisa wonke amabhodi e-PCB.Eqinisweni, amabhodi e-PCB ahlukile, imikhiqizo eyenziwe ikhasimende ngalinye ihlukile, futhi izinhlobo zamabhodi e-PCB nazo zihlukile.Ngakho-ke, kuyadingeka ukukhetha okuhlukileumshini wokugcwalisaamabhodi e-PCB ahlukene., Eyokuqala ibhodi le-PCB elinezingxenye.Lapho izingxenye zingephezulu futhi ibhodi le-PCB lingelikhulu, kutuswa ukuba ukhethe uhlobo lommesepcb umshini wokusika.Ukuguquguquka kwayo kunamandla kakhulu.Ngemuva kokuthi amabhodi e-PCB axhunyiwe amaningi esethengisiwe, kulula ukulimaza isekethe noma ukuphula izingxenye ze-elekthronikhi.Hamba, ummese oyisiyingi ongaphezulu uhamba uvundlile uye endaweni ebekiwe, okungukuthi, ibhodi le-PCB liyasikwa futhi lihlukaniswe, futhi ukusika akuwi ocingweni, i-incision iyisicaba, futhi ayikho i-burr.Iplathifomu yokuthutha ingafakwa futhi ukuze kube lula ukulethwa okuzenzakalelayo kwebhodi le-PCB elisikiwe, ngaleyo ndlela kuncishiswe ingcindezi, kuvinjwe ukuqhekeka kwamalungu e-solder nokuphuka kwezingxenye, nokwenza ngcono ukusebenza kahle kokukhiqiza kanye nekhwalithi.

1A imishini yokusika

Eyesibili ibhodi elincane uma kuqhathaniswa.Ibhodi le-PCB lilula ekwakhiweni, kodwa lincane kakhulu.Kunconywa ukukhetha i-guillotineumsiki we-pcb.Umshini wokuhlukanisa uhlobo lwe-guillotine wamukela umklamo wakamuva we-gas-electric light-weight, ongaqedela ukusika ngaphandle kokucindezeleka kwe-shear ngesikhathi esisodwa, ofaneleka ngokukhethekile ukusika ukunemba kwe-SMD noma amapuleti amancane;ngaphandle kwegagasi lomnsalo kanye nemifantu emincane ekhiqizwa lapho ukuhlukaniswa kohlobo lommese oyindilinga, sebenzisa ukuhlukanisa okuqondile kwethuluzi elimise okwe-Wedge kunciphisa ukucindezelwa kwe-shear, ukuze izingxenye ezibucayi ze-SMD, ngisho nama-capacitor, zingathinteki, kanye nezingozi ezingaba khona zekhwalithi yomkhiqizo zincishiswe.Ngaphezu kwalokho, kukhona lezo ezingavamile, imbobo isitembu, ibhuloho PCB amabhodi, kutuswa ukuba ukhethe ijika.isihlukanisi se-pcb.I-curve splitter ibizwa nangokuthi i-milling cutter type splitter.Ikakhulukazi iyisisetshenziswa esisebenzisa ukusebenza ngesivinini esiphezulu kwesisiki sokugaya ukuhlukanisa i-PCB eneziqephu eziningi ngokwendlela ehlelwe ngaphambilini, esikhundleni sokuphuka kwezandla noma ukusika amaphutha.V-CUTnoma PUSH, ukusika Ukunemba okuphezulu nokunemba, impilo yesevisi ende, ikhwalithi enhle yokusika, akukho uthuli, akukho burrs, ukucindezeleka okuphansi, ukuphepha kanye nokulula, ukuthuthukisa ikhwalithi yomkhiqizo nokunciphisa izinga le-scrap.Isetshenziswa kakhulu ukuhlukanisa amabhodi e-PCB angajwayelekile, amabhodi embobo yezitembu, namabhodi okuxhumanisa.Ukucindezeleka kokusika kuncane, mayelana ne-1/10 yohlobo lokugxiviza kanye ne-1/100 yohlobo lokuphulwa kwesandla, ukuze kuvinjwe ama-chips afana nama-capacitors e-ceramic ukuba angalinyazwa ngesikhathi sokusika;gwema ukuqhekeka kwethini kanye nokulimala kwengxenye okubangelwa ukugoqa okwenziwa ngesandla.
