Umshini wokunamathisela wamagagasi okhethiweinikeza indlela entsha yokushisela, enezinzuzo ezingenakuqhathaniswa ngaphezu kwe-welding manual, yendabukoumshini we-wave solderingkanye nomgodireflow oven.Kodwa-ke, ayikho indlela yokushisela engaphelele, futhi i-wave soldering ekhethiwe nayo inezinye "imikhawulo" enqunywa izici zemishini.
1. I-wave soldering nozzle ekhethiwe ingaya phezulu naphansi kuphela, izinhlangothi kwesokunxele nakwesokudla, akukho ukugcwaliseka kokujikeleza kwe-3 d, i-wave soldering crest ekhethiwe iqondile, ayiyona igagasi elivundlile (i-lateral wave), ngakho-ke okufanayo kufakwe kusixhumi sikagesi. odongeni lwesivalo se-microwave, isivikelo nesifakwe mpo ezingxenyeni zebhodi le-motherboard ebhodini lesifunda eliphrintiwe kunzima ukusebenzisa ukushisela, Ukuze i-rf connector assembly kanye ne-multi-core cable assembly ayikwazi ukuqaliswa ukushisela, yebo, i-wave soldering yendabuko kanye ne-reflow welding ayikwazi ukwenziwa;Ngisho ne-robot welding, kukhona "imikhawulo" ethile.
2. Umkhawulo wesibili we-elective wave soldering uyisivuno.I-wave soldering yendabuko yiyona yonke ibhodi lesifunda ngesikhathi esisodwa, ukukhetha kwe-welding yi-point welding noma i-nozzle welding encane, kodwa ngokuthuthuka okusheshayo kwemboni kagesi, ngokusebenzisa izingxenye zembobo kancane kancane, ukukhiqiza ngokusebenzisa umklamo we-modularization wokukhetha amagagasi e-wave soldering, i-multi-cylinder parallel ithuthukisiwe, ikakhulukazi ukusungulwa kobuchwepheshe baseJalimane, umthamo wokukhiqiza ube yingxenyana.
3. I-Wave soldering ADAPTS ekhethiwe kuya engxenyeni yezikhala zephini (ibanga elimaphakathi).Ekuhlanganiseni kwabantu abaningi kakhulu kwe-PCBA, ukuhlukaniswa kwezixhumi zikagesi kanye namasekethe ahlanganisiwe anemigqa emibili (i-DIP) kuya ngokuya kuncipha, ukuhlukaniswa kwezixhumi zikagesi nezikhonkwane ezihlanganisiwe (i-DIP) eziphindwe kabili emgqeni (ibanga elimaphakathi) incishisiwe isuka ku-1.27mm yaya ku-0.5mm noma ngaphansi;Lokhu kuletha izinselelo ekuhlanganisweni kwamagagasi okujwayelekile kanye nokuqoqwa kwamagagasi okukhethayo.Uma isikhala sephinikhodi sesixhumi sikagesi singaphansi kuka-1.0mm noma sifinyelela ku-0.5mm, ukushisela kwephoyinti nephoyinti kuzokhawulwa ngosayizi womlomo womlomo, futhi i-drag welding izokwandisa isici sokushisela indawo yokushisela.Ngakho-ke, ukungalungi kwe-wave soldering ekhethiwe kuqokonyiswa emhlanganweni we-high-density.
4. Uma kuqhathaniswa ne-wave soldering yendabuko, ibanga lokushisela lemishini yokushisela ekhethiwe lingaba lincane kunalelo le-wave soldering yendabuko ngenxa yomsebenzi wayo okhethekile wamajoyini okuthengisa "amancane".Ukushisela okuthembekile kungafinyelelwa ezingxenyeni zembobo enebanga lephini elikhulu noma elilingana no-2mm;Ezingxenyeni zembobo ezinebanga lephinikhodi elingu-1 ~ 2mm, indawo yokushisela “encane” umsebenzi wezinto zokusebenza kufanele isetshenziswe ukuze kuzuzwe ukushiselwa okuthembekile;Ezingxenyeni zembobo enebanga lephini elingaphansi kuka-1mm, kuyadingeka ukuklama umlomo wombhobho okhethekile futhi usebenzise inqubo ekhethekile yokufeza ukushisela okungenasici.
5. Uma ibanga elimaphakathi lesixhumi sikagesi lingaphansi noma lilingana no-0.5mm, sebenzisa ubuchwepheshe bokuxhuma okungenakhebula obuthuthuke kakhulu.
I-selective wave soldering inezidingo eziqinile ekwakhiweni kwe-PCB nobuchwepheshe, kodwa kuseneziphambeko zokushisela, njengobuhlalu bethini, okunzima kakhulu ukukuxazulula.
6. Izinto ezisetshenziswayo ziyabiza, umshini wokugcwalisa igagasi okhethiwe wezinga eliphansi ubiza cishe u-$200,000, futhi ukusebenza kahle kokukhetha okukhethiwe kwe-wave soldering kuphansi.Njengamanje, i-wave soldering ethuthuke kakhulu ekhethiwe idinga umjikelezo we-5s, futhi i-PCB enezingxenye eziningi zembobo, ayikwazi ukuhambisana nebhithi yokukhiqiza ekukhiqizeni ngobuningi, futhi izindleko zinkulu.
