Kwindibano ye-PCBA, ukhetho lwezinto eziphathekayo lubalulekile ekusebenzeni kwebhodi kunye nokuthembeka.Nazi ezinye iingqwalasela kwi-solder, iPCB kunye nokukhethwa kwezinto zokupakisha:
Iingqwalasela zokukhetha i-solder
1. IKhokelo yasimahla yeSolder vs
I-solder-free solder ixabiswa ngenxa yobuhlobo bayo bokusingqongileyo, kodwa kubalulekile ukuqaphela ukuba inamaqondo aphezulu okushisa.I-solder ehamba phambili isebenza kumaqondo aphantsi, kodwa kukho imingcipheko yokusingqongileyo kunye nempilo.2.
2. Indawo yokunyibilika
Qinisekisa ukuba i-melting point ye-solder ekhethiweyo ifanelekile kwiimfuno zeqondo lokushisa kwenkqubo yendibano kwaye ayiyi kubangela umonakalo kumacandelo anobungozi obushushu.
3. Ulwelo
Qinisekisa ukuba i-solder ine-fluidity efanelekileyo yokuqinisekisa ukumanzisa okwaneleyo kunye nokudibanisa kwamalungu e-solder.
4. Ukumelana nobushushu
Ukusetyenziswa kweqondo lokushisa eliphezulu, khetha i-solder enokumelana nokushisa okulungileyo ukuqinisekisa ukuzinza ngokubambisana kwe-solder.
Iingqwalasela zokukhetha imathiriyeli yePCB
1. Izinto eziphathekayo
Khetha izinto ezifanelekileyo ze-substrate, ezifana ne-FR-4 (i-glass fiber reinforced epoxy resin) okanye ezinye izinto ezihamba phambili, ngokusekelwe kwiimfuno zesicelo kunye neemfuno ze-frequency.
2. Inani leeLeya
Qinisekisa inani leeleya ezifunekayo kwi-PCB ukuhlangabezana neemfuno zomzila wesignali, umhlaba kunye neenqwelomoya zamandla.
3. Ukuphazamiseka kophawu
Qonda i-impedance yeempawu zezinto ezikhethiweyo ze-substrate ukuqinisekisa imfezeko yomqondiso kunye nokuhambelana neemfuno zesibini.
4. I-Thermal Conductivity
Kwizicelo ezifuna ukutshatyalaliswa kobushushu, khetha i-substrate material ene-conductivity efanelekileyo ye-thermal ukunceda ukukhupha ukushisa.
Iingqwalasela zokukhetha imathiriyeli yokupakisha
1. Uhlobo lwephakheji
Khetha uhlobo lwephakheji efanelekileyo, njenge-SMD, i-BGA, i-QFN, njl., ngokusekelwe kuhlobo lwecandelo kunye neemfuno zesicelo.
2. Imathiriyeli ye-encapsulation
Qinisekisa ukuba izinto ezikhethiweyo ze-encapsulation ziyahlangabezana neemfuno zokusebenza kombane kunye noomatshini.Cinga izinto ezifana noluhlu lweqondo lokushisa, ukumelana nobushushu, amandla omatshini, njl.
3. Ukupakisha ukusebenza kwe-thermal
Kumacandelo afuna ukutshatyalaliswa kobushushu, khetha imathiriyeli yepakethe enokusebenza kakuhle kwe-thermal, okanye ucinge ngokungongeza i-heat sink.
4. Ubungakanani bepakethi kunye ne-pin isithuba
Qinisekisa ukuba ubungakanani kunye nesithuba sephini lepakethe ekhethiweyo ifanelekile kuyilo lwePCB kunye noyilo lwecandelo.
5. Ukhuseleko lokusingqongileyo kunye nozinzo
Cinga ngokukhetha izinto ezihambelana nokusingqongileyo ezihambelana nemigaqo kunye nemigangatho efanelekileyo.
Xa ukhetha ezi mathiriyeli, kubalulekile ukusebenza ngokusondeleyo kunye nabavelisi be-PCBA kunye nabathengisi ukuqinisekisa ukuba ukukhethwa kwezinto eziphathekayo kuyahlangabezana neemfuno zesicelo esithile.Kwakhona, ukuqonda iingenelo, ukungalungi kunye neempawu zezinto ezahlukeneyo, kunye nokufaneleka kwazo kwizicelo ezahlukeneyo, kungundoqo ekwenzeni ukhetho olunolwazi.Ukuthathela ingqalelo uhlobo oluhambelanayo lwe-solder, i-PCB kunye nezinto zokupakisha ziqinisekisa ukusebenza kunye nokuthembeka kwe-PCBA.
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.
Kule minyaka ilishumi, siye savelisa ngokuzimeleyo iNeoDen4, NeoDen IN6, NeoDen K1830, NeoDen FP2636 kunye nezinye iimveliso ze-SMT, ezithengiswe kakuhle kwihlabathi jikelele.Ukuza kuthi ga ngoku, sithengise ngaphezulu koomatshini be-10,000pcs kwaye sabathumela kumazwe angaphezu kwe-130 kwihlabathi liphela, siseka igama elihle kwimarike.Kwi-Ecosystem yethu yehlabathi, sisebenzisana nelona qabane lethu libalaseleyo ukuhambisa inkonzo evalayo yokuthengisa, inkxaso ephezulu yobuchwephesha kunye neyobuchule.
