Inqubo yokusebenzisa ibhodi le-PCBA, ngokuvamile kuyoba khona isenzakalo se-pad off, ikakhulukazi ngesikhathi sokukhanda ibhodi le-PCBA, uma usebenzisa insimbi yokunamathisela, kulula kakhulu ukudonsa i-pad off the phenomenon, i-PCB factory kufanele ibe kanjani ukubhekana nayo?Kuleli phepha, izizathu ze-pad off some analysis.
1. Izinkinga zekhwalithi yepuleti
Ngenxa ye-copper-clad laminate plate ucwecwe lwethusi kanye ne-epoxy resin phakathi kwe-resin adhesive adhesion bonding impofu, okungukuthi, ngisho noma indawo enkulu ye-foil yethusi yebhodi lesifunda i-foil yethusi ishise kancane noma ingaphansi kwamandla omshini, inamandla kakhulu. kulula ukuhlukana ne-epoxy resin okuholela ekucishweni kwamaphedi noma ukucishwa kwe-copper foil kanye nezinye izinkinga.
2. Umthelela wemibandela yokugcina ibhodi lesifunda
Ithintwa isimo sezulu noma isitoreji eside endaweni enomswakama, ukumuncwa komswakama webhodi le-PCB kuholela kumswakama omningi, ukuze kuzuzwe umphumela ofisa ukushisela, i-patch welding ukunxephezela ukushisa okuthathwe ngenxa yokuhwamuka komswakama, izinga lokushisa lokushisela nesikhathi. kufanele inwetshwe, izimo zokushisela ezinjalo zivame ukubangela ucwecwe lwethusi lwebhodi lesifunda kanye ne-epoxy resin delamination, ngakho-ke indawo yokucubungula ye-PCB kufanele inake umswakama wemvelo lapho igcina ibhodi le-PCB.
3. Izinkinga zokushisela insimbi
Okujwayelekile PCB ibhodi adhesion kungaba ukuhlangabezana Welding ezivamile, ngeke kube khona pad off mkhuba, kodwa imikhiqizo electronic ngokuvamile kungenzeka ukulungisa, ukulungisa ngokuvamile kusetshenziswa soldering iron Welding ukukhanda, ngenxa izinga lokushisa eliphezulu lendawo lensimbi soldering ngokuvamile ifinyelela 300- I-400 ℃, okuholela ekushiseni okuphezulu kwendawo ngokushesha kwephedi, ukushiselwa kwe-resin ngaphansi kwe-foil yethusi ngokuwa kwezinga lokushisa eliphezulu, ukubonakala kwe-pad off.Ukudilizwa kwensimbi ye-soldering kulula futhi ngengozi ye-solder yensimbi ekhanda kumandla we-welding disc, okuholela futhi ekubangeleni kwe-pad off.
Izici zeI-NeoDen IN12C Refow Oven
1. Isistimu yokuhlunga intuthu eyakhelwe ngaphakathi, ukuhlunga okusebenzayo kwamagesi ayingozi, ukubukeka okuhle nokuvikelwa kwemvelo, okuhambisana kakhulu nokusetshenziswa kwendawo ephezulu.
2. Uhlelo lokulawula lunezici zokuhlanganiswa okuphezulu, ukuphendula ngesikhathi, izinga lokuhluleka eliphansi, ukugcinwa okulula, njll.
3. Umklamo wemojula yokushisa oyingqayizivele, ngokunemba okuphezulu kokulawula izinga lokushisa, ukusatshalaliswa kokushisa okufanayo endaweni yesinxephezelo esishisayo, ukusebenza kahle okuphezulu kwesinxephezelo esishisayo, ukusetshenziswa kwamandla aphansi nezinye izici.
4. Umklamo wokuvikela ukushisa ukushisa, izinga lokushisa legobolondo lingalawulwa ngokuphumelelayo.
5. Ingagcina amafayela asebenzayo angama-40.
6. Isibonisi sesikhathi sangempela esingafika ku-4 we-PCB board surface welding lokushisa ijika.
7. I-lightweight, i-miniaturization, idizayini yemboni yobungcweti, izimo zohlelo lokusebenza eziguquguqukayo, ubuntu obuningi.
8. Ukonga amandla, ukusetshenziswa kwamandla okuphansi, izidingo zokuphakelwa kwamandla aphansi, ugesi ovamile ongahlangabezana nokusetshenziswa, uma kuqhathaniswa nemikhiqizo efanayo ngonyaka kungonga izindleko zikagesi bese uthenga iyunithi engu-1 yalo mkhiqizo.
