KwePCBinqubo yokuhlanganisa kanye ne-soldering, abakhiqizi bokucubungula ama-chip e-SMT banabasebenzi abaningi noma amakhasimende abambe iqhaza ekusebenzeni, njengokufakwa kwe-plug-in, ukuhlolwa kwe-ICT, ukuhlukaniswa kwe-PCB, ukusebenza kwe-PCB esebenza ngesandla, ukufaka isikulufu, ukukhweza i-rivet, ukucindezela kwe-crimp isixhumi ngesandla, ukuhamba ngebhayisikili nge-PCB, njll., ukusebenza okuvamile ngumuntu oyedwa othatha ibhodi ngesandla esisodwa, okuyisici esiyinhloko ekuhlulekeni kwe-BGA nama-chip capacitors.Pho kungani lokhu kubangela ukungasebenzi kahle?Vumela umhleli wethu akuchazele namuhla!
Izingozi zokubamba i-PCBibhodi ngesandla esisodwa:
(1) Ukubamba ibhodi le-PCB ngesandla esisodwa ngokuvamile kuvunyelwe kulawo mabhodi esekethe anosayizi omncane, isisindo esilula, awekho i-BGA futhi awekho umthamo we-chip;kodwa kulawo ma-circuits anobukhulu obukhulu, isisindo esinzima, i-BGA kanye ne-chip capacitors emabhodini aseceleni, okufanele nakanjani kugwenywe.Ngoba lolu hlobo lokuziphatha lungabangela kalula amalunga e-solder e-BGA, i-chip capacitance ngisho nokumelana ne-chip ukuthi kuhluleke.Ngakho-ke, embhalweni wenqubo, izidingo zendlela yokuthatha ibhodi lesifunda kufanele ziboniswe.
Ingxenye elula yokubamba i-PCB ngesandla esisodwa inqubo yomjikelezo webhodi lesifunda.Ukuthi ukhipha ibhodi ebhandeni lokuthutha noma ubeka ibhodi, abantu abaningi bangena ngokungazi bathatha umkhuba wokubamba i-PCB ngesandla esisodwa ngoba iyona elula kakhulu.Uma unamathisela ngesandla, namathisela irediyetha bese ufaka izikulufu.Ukuze uqedele umsebenzi, uzosebenzisa isandla esisodwa ukuze usebenzise ezinye izinto ebhodini.Le misebenzi ebonakala ijwayelekile ivamise ukufihla izingozi ezinkulu zekhwalithi.
(2) Faka izikulufu.Ezimbonini eziningi ze-SMT chip processing, ukuze kongiwe izindleko, ukufakwa kwamathuluzi akufakiwe.Uma izikulufi zifakwa ku-PCBA, izingxenye ezingemuva kwe-PCBA zivame ukonakala ngenxa yokungalingani, futhi kulula ukuqhekeza amalunga e-solder azwela ukucindezeleka.
(3) Ukufaka izingxenye zembobo
Izingxenye zembobo, ikakhulukazi ama-transformer anemikhondo eqinile, ngokuvamile kunzima ukufaka ngokunembile emigodini ekhuphukayo ngenxa yokubekezelelana kwesikhundla esikhulu somkhondo.Ama-opharetha ngeke azame ukuthola indlela yokunemba, ngokuvamile esebenzisa ukucindezela okuqinile, okuzobangela ukugoba nokuguqulwa kwebhodi le-PCB, futhi kuzodala nomonakalo kuma-chip capacitor, resistors, kanye ne-BGA ezungezile.
