Emva kokoUkuthengiswa kwakhona kwe-SMTsiya kuhlangabezana neziganeko ezineziphene, ezi ziphene ze-SMT zokucwangcisa i-solder ziya kuchaphazela ngokuthe ngqo okanye ngokungathanga ngqo umgangatho wemveliso.Ezi ziganeko zineziphene zicacile zabaqhubi be-SMT kwisigqibo seziphene zokulungisa iziphene, ukuze kubonelelwe ngebenchmark yoshishino yokuphuculwa kwemveliso kunye nokusebenza kwegama elibi.Kweyona nkqubo yokusetyenzwa kwezi ziphene zifunyenweyo, kufuneka zisetyenziselwe ngokungqongqo okanye unyango lokulungisa.Ngoko ke sifanele siqonde njani ukuze siqonde isiganeko esibi?
Ngezantsi ukuze ulungise oku kulandelayo:
1. (kwanetoti) i-SMT processing welding even tin ikwabizwa ngokuba yi-tin bhulorho, phakathi kweziphelo zecandelo, phakathi kwamalungu adityanisiweyo e-solder amacandelo, kunye namalungu e-solder kunye neengcingo ezikufutshane, ukugqobhoza, njl. i-solder edityaniswe kunye, ishishini lokucubungula i-SMT elibizwa ngokuba yi-tin.
2. (ilitye lesikhumbuzo) ilitye lengcwaba, elikwabizwa ngokuba yi-Manhattan phenomenon, libhekiselele kwisiphelo sokudambisa ezibini zamacandelo etshiphu, emva kokuphinda kufakwe i-solder, esinye sesiphelo sokusongenya sisuka kumphezulu wepad wecandelo lonke sasityebile kwaye sithe tye.Ishishini le-SMT elibizwa ngokuba sisikhumbuzo.
3. (icala lokuma) icala lecandelo le-chip kunye ne-PCB pad isenzeko soqhagamshelwano.ishishini le-SMT elibizwa ngokuba yi-side stand.
3
5. (anti-mhlophe) isiqwenga secandelo elingaphambili kwi-PCB, icala elisezantsi ukuya phezulu.
6. (amaso enkcenkce) kwi-reflow soldering, edityaniswe kwiqhekeza lenxalenye yecandelo okanye usasazwe kwi-solder joints isihlomelo amaso amancinane e-solder.
7. (i-cold soldering) i-reflow phenomenon engaphelelanga, i-solder ayifikeleli kwindawo yokunyibilika kweqondo lokushisa okanye ukushisa kwe-welding akwanelanga, ukwenzela ukuba iqiniswe phambi kokumanzisa kunye nokuhamba, akukho kwakheka kwayo nayiphi na i-alloy layer yesinyithi, ukwenzela ukuba yonke into idibene. okanye inxalenye ye-solder kwimeko engekho-crystalline kwaye yakha nje phezulu phezu kwentsimbi ethengiswayo.
8. (i-core suction) i-solder esuka kwi-pad ecaleni kwephini ukunyuka ukuya kwi-pin kunye nomzimba wetshiphu, okukhokelela kwi-solder enganelanga okanye i-solder engenanto kwiindawo ze-solder.
9. (i-reverse) ibhekisela kwi-polarity yamacandelo emva kwe-welding, i-polarity yesalathiso seemfuno zangempela zesikhokelo asihambelani.
10. (i-bubble) i-solder ekuqinisweni kwegesi ngaphambi kokusilela ukubaleka ngexesha, ukubunjwa kwesiganeko esingenanto ngaphakathi kwi-joint solder.
11. (i-pinhole) kwindawo edibeneyo ye-solder ukwenza imingxuma efana nenaliti.
12. (i-fissure) i-solder joints ngenxa yoxinzelelo lwe-mechanical okanye uxinzelelo lwangaphakathi olubangelwa yi-phenomenon of cracked joints solder.
13. (incam yenkcenkce) ukuwelda kwitoti ephuma ngaphandle efana nenaliti okanye e-spiky.
14. (i-tin engaphezulu) i-soldering kwi-solder ingaphezulu kwexabiso eliqhelekileyo lemfuno, ukuze kube nzima ukubona ulwandlalo lwamacandelo athengiswayo okanye i-solder ukwenza imfumba ye-spherical.
15. (i-solder evulekileyo) izikhonkwane zecandelo / isiphelo se-solder sazo zonke ngaphandle okanye kude neepads ezihambelanayo, kwaye kungekhona ngenxa ye-soldering.
16. (amabala amhlophe) avele kwi-substrate e-laminated ngaphakathi kwesenzeko, apho imicu yeglasi kwi-longitudinal kunye ne-transverse crossings kunye nokuhlukana kwe-resin.Esi siganeko sibonakaliswa njengamabala amhlophe amhlophe okanye indawo engaphantsi kwe-substrate phantsi "kwe-cross-shaped", ngokuqhelekileyo ihambelana nokubunjwa koxinzelelo ngenxa yokushisa.
17. (i-welding grey) ngenxa yokushisa okuphezulu kwe-welding, ukugqithiswa kwe-flux evaporation kunye ne-welding ephindaphindiweyo, njl., ubuso be-weld bubomvu, i-crystal solder ikhululekile, i-porous kunye ne-slag-like.
I-Zhejiang NeoDen Technology Co., LTD., Yasekwa ngo-2010, ngumvelisi oqeqeshiweyo okhethekileyo kwi-SMT pick and place machine, i-oven reflow, umatshini wokushicilela we-stencil, umgca wemveliso we-SMT kunye nezinye iiMveliso ze-SMT.Sineqela lethu le-R & D kunye nemizi-mveliso yethu, sithatha ithuba le-R&D yethu etyebileyo, imveliso eqeqeshwe kakuhle, yaphumelela igama elihle kubathengi behlabathi ngokubanzi.
Sikwindawo entle ukuba singakuboneleli kuphela ngoomatshini bepnp abakumgangatho ophezulu, kodwa kunye neyona nto ibalaseleyo emva kwenkonzo yokuthengisa.
Iinjineli eziqeqeshwe kakuhle ziya kukunika nayiphi na inkxaso yobugcisa.
Iinjineli ezili-10 ezinamandla kwiqela lenkonzo emva kokuthengisa zinokuphendula imibuzo yabathengi kunye nemibuzo kwiiyure ezisi-8.
Izisombululo zobungcali zinokunikezelwa kwiiyure ezingama-24 zombini imini yokusebenza kunye neeholide.
