Izinyathelo zokusebenza ze-Wave soldering kanye namaphoyinti ukuze unakwe.

1. Izinyathelo zokusebenza zeumshini we-wave soldering.

1).Imishini ye-Wave solderingukulungiselela ngaphambi kokushisela
Hlola ukuthi i-PCB ezodayiswa imanzi yini, noma amajoyinti e-solder ane-oxidized, akhubazekile, njll.;i-flux ixhunywe ku-nozzle interface ye-sprayer.

2).Ukuqaliswa kwemishini yokugcwalisa i-wave soldering
Lungisa ububanzi bebhande le-wave soldering machine drive (noma indawo) ngokuya ngobubanzi bebhodi lesifunda eliphrintiwe;vula amandla kanye nomsebenzi we-fan ngayinye yomshini we-wave soldering.

3).Setha imingcele ye-welding yemishini ye-wave soldering
I-Flux Flow: Kuya ngokuthi i-flux ithinta kanjani phansi kwe-PCB.I-flux iyadingeka ukuthi iboshwe ngokulinganayo phansi kwe-PCB.Kusukela embobeni ku-PCB, kufanele kube nenani elincane lokugeleza ebusweni bembobo elingena lisuka embobeni liye kuphedi, kodwa lingangeni.

Izinga lokushisa elishisayo ngaphambi kokushisa: setha ngokwesimo sangempela sendawo yokushisa kuhhavini we-microwave (izinga lokushisa langempela endaweni engaphezulu ye-PCB ngokuvamile liyi-90-130 ° C, izinga lokushisa lepuleti eliwugqinsi liwumkhawulo ophezulu webhodi elihlanganisiwe elinokuningi. Izingxenye ze-SMD, kanye nokwenyuka kwezinga lokushisa kungaphansi noma kulingana no-2°C/S;

Isivinini sebhande le-Conveyor: ngokusho kwemishini ehlukene yokuhlanganisa amaza nezilungiselelo ze-PCB okufanele zithengiswe (ngokuvamile i-0.8-1.60m/min);izinga lokushisa le-solder: (kufanele kube izinga lokushisa eliphakeme langempela eliboniswa ensimbini (SN-Ag-Cu 260±5℃ , SN-Cu 265±5°C). Njengoba inzwa yezinga lokushisa ikubhavu kathini, izinga lokushisa lemitha noma i-LCD icishe ibe ngu-3°C ngaphezu kwezinga lokushisa eliphakeme langempela;

Isilinganiso sobude obuphakeme: uma sidlula phansi kwe-PCB, lungisa sibe ngu-1/2~2/3 wogqinsi lwe-PCB;

I-angle ye-Welding: ukuthambekela kokudlulisela: 4.5-5.5 °;isikhathi Welding: ngokuvamile 3-4 imizuzwana.

4).Umkhiqizo kufanele udayiswe futhi uhlolwe (ngemuva kokuthi yonke imingcele ye-welding ifinyelela inani elimisiwe)
Beka ngobumnene ibhodi lesifunda eliphrintiwe ebhandeni lokuthutha (noma i-fixture), umshini ngokuzenzakalelayo ufafaza i-rib flux, ukushisa kuqala, ama-wave solders kanye nokupholisa;ibhodi lesifunda eliphrintiwe lixhunywe ekuphumeni kwe-wave soldering;ngokwezinga lokuhlola imboni.

5).Lungisa amapharamitha wokushisela ngokuya ngemiphumela yokushisela ye-PCB

6).Yenza ukukhiqizwa kokushisela okuqhubekayo, xhuma ibhodi lesifunda eliphrintiwe endaweni yokukhipha i-wave soldering, ulibeke ebhokisini le-anti-static turnover ngemva kokuhlolwa, bese uthumela ibhodi lokulungisa ukuze licutshungulwe ngokulandelayo;ngesikhathi senqubo yokushisela eqhubekayo, ibhodi ngalinye eliphrintiwe kufanele lihlolwe, futhi amaphutha okushisela Amabhodi aphrintiwe aqinile kufanele aphinde athengiswa ngokushesha.Uma kusekhona amaphutha ngemuva kokushisela, imbangela kufanele itholakale, futhi ukuthungatha kufanele kuqhutshwe ngemva kokulungisa imingcele yenqubo.

2. Amaphuzu okunakwa ekusebenzeni kwe-wave soldering.

1).Ngaphambi kwe-wave soldering, hlola isimo sokusebenza kwemishini, ikhwalithi yebhodi lesifunda eliphrintiwe elizodayiswa kanye nesimo se-plug-in.

2).Enkambweni yokuhlanganisa i-wave soldering, kufanele uhlale unaka ukusebenza kwemishini, uhlanze ama-oxide ebusweni bokugeza kwe-tin ngesikhathi, engeza i-polyphenylene ether noma uwoyela wesesame namanye ama-antioxidants, futhi ugcwalise i-solder ngesikhathi.

3).Ngemuva kwe-wave soldering, ikhwalithi ye-welding kufanele ihlolwe i-block by block.Ngenani elincane lamaphoyinti e-soldering alahlekile kanye namabhuloho, ukulungiswa kwe-welding manual kufanele kwenziwe ngesikhathi.Uma kunezinkinga eziningi zekhwalithi yokushisela, thola izizathu ngesikhathi.

I-Wave soldering iyindlela evuthiwe yokuhlanganisa izimboni.Kodwa-ke, ngenani elikhulu lezicelo zezingxenye zokukhweza kwendawo, inqubo yokuhlanganisa exubile yezingxenye ze-plug-in kanye nezingxenye zokukhweza ngaphezulu ezihlanganiswe ebhodini lesifunda ngesikhathi esifanayo sekuyifomu elivamile lokuhlanganisa emikhiqizweni ye-elekthronikhi, ngaleyo ndlela inikeze imingcele yenqubo eyengeziwe. ubuchwepheshe be-wave soldering.Ukuze kuhlangatshezwane nezidingo eziqinile, abantu basahlola njalo izindlela zokuthuthukisa ikhwalithi ye-soldering ye-wave soldering, okuhlanganisa: ukuqinisa ukulawulwa kwekhwalithi yokuklama kwebhodi lesifunda eliphrintiwe kanye nezingxenye ngaphambi kwe-soldering;ukwenza ngcono izinto zenqubo ezifana ne-flux kanye ne-solder Ukulawulwa kwekhwalithi;ngesikhathi senqubo yokushisela, thuthukisa imingcele yenqubo efana nokushisa kwangaphambi kokushisa, ukuthambekela kwethrekhi ye-welding, ukuphakama kwegagasi, izinga lokushisa lokushisela nokunye.
