Isiseko sokusetyenzwa kwe-SMT yi-PCB, eyahlulwa ngenani leeleya, ezifana ne-2-layer PCB kunye ne-4-layer PCB.Okwangoku, ukuya kuthi ga kwimigangatho engama-48 inokufezekiswa.Ngokobuchwephesha, inani leeleya linamathuba angenamkhawulo kwixesha elizayo.Ezinye ii-supercomputers zineeleya ezingamakhulu.Kodwa ezona zixhaphakileyo kwi-elektroniki yezonyango okanye kwi-automotive electronics zihlala zinemigangatho emibini okanye emine.Ukuba ufuna ukukhetha iileya zebhodi yakho ngokufanelekileyo, qonda umahluko phakathi kwe-2 kunye ne-4 umaleko.
Ibhodi yeSekethe eprintiweyo e-2
Xa kuthelekiswa ne-4-layer PCBS, 2-umaleko PCBS kulula ukuyisebenzisa ngenxa yoyilo lwabo olulula.Ngelixa zingelula njenge-1-layer PCBS, zilula kangangoko ngaphandle kokuncama ukusebenza kwegalelo elimacala amabini.Ubunzima obuncitshisiweyo buphumela kwithegi yexabiso elifanayo elincitshisiweyo, kodwa lithetha amathuba ambalwa xa kuthelekiswa ne-4-layer PCBS.Nangona kunjalo, njengebhodi yesekethe esetyenziswa ngokuqhelekileyo kushishino, inenzuzo ebalulekileyo yokungabikho kokulibaziseka kokusasazwa komqondiso.

I-4-layer PCB inomhlaba omkhulu kune-PCB ene-2-layer, inyusa ukuba nokwenzeka kweengcingo ezininzi.Ngaloo ndlela, zifaneleke kakuhle izixhobo ezinzima ngakumbi.Ngenxa yokuntsonkotha kwazo, zibiza kakhulu ukuvelisa kwaye zicotha ukuphuhlisa.Kwakhona kunokwenzeka ukuba babe nokulibaziseka kokusasaza okanye ukusebenzisana, ngoko ke uyilo olufanelekileyo lubaluleke kakhulu.
Ke yintoni ukusetyenziswa kweeLayers?
Owona maleko ubalulekileyo kwi-PCB ngumaleko wefoyile yobhedu, eligama lePCB.Ngelixa i-2-layer PCB ineempawu ezimbini zomaleko, i-PCB ene-4 inezine.Ezi maleko zomqondiso zisetyenziselwa ukudibanisa amanye amalungu e-elektroniki kwisixhobo.Phakathi kwezi zingqimba kukho i-insulating layers, okanye i-cores, ezongezwa phakathi kweempawu zesignali ukuze zinike isakhiwo.Kwi-PCB ye-4-layer, kukho kwakhona i-solder barrier layer, esetyenziswe phezulu kwinqanaba lesignali.Oku kuthintela umkhondo wobhedu ekuphazamiseni amanye amacandelo esinyithi kwi-PCB.Kananjalo banomaleko we-silkscreen wokongeza amanani kumacandelo ahlukeneyo ukwenza kube lula ukuwabeka.
I-Zhejiang NeoDen Technology Co., LTD., yasekwa ngo-2010, ngumvelisi oyingcali okhethekileyoSMT khetha kwaye ubeke umatshini, reflow oven,umatshini wokushicilela we-stencil, Umgca wokuvelisa 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.
Sikholelwa ukuba abantu abakhulu kunye namahlakani enza iNeoDen ibe yinkampani enkulu kwaye ukuzinikela kwethu kuTshintsho, iyantlukwano kunye noZinzo kuqinisekisa ukuba i-SMT automation iyafikeleleka kuye wonke umntu othanda ukuzonwabisa kuyo yonke indawo.
