Okokuqala, ndingathanda ukwazisa yethuPCB icocekileumatshini wokuhlambakwayeumatshini wokucoca umnatha wentsimbi:
Umatshini wokucoca we-PCB yibrashi yokucoca uhlobo olunye lomatshini wokucoca.Isetyenziswa phakathi komlayishi kunyeUkuprintwa kwestencilumatshini, ezifanelekileyo kwiimfuno ze-AI kunye ne-SMT zokucoca, zinokufikelela kwiimfuno zomgangatho ophezulu kakhulu wokucoca.
Umatshini wokucoca umnatha wentsimbiisetyenziselwa ukucoca umnatha wentsimbi.
Kutheni ufuna ukucocwa kwePCBA?Ziziphi iingenelo?
Yonke i-PCBA ngexesha lokucutshungulwa, ngakumbi kwinkqubo ye-teknoloji ye-welding, iya kuba ne-solder paste, i-solder, i-solder wire, i-flux residues, i-residus kwi-PCBA layout iya kwenza imithombo engundoqo yongcoliseko, intsalela ukuba ayicocekanga, inokubangela ukubola. isiphaluka, isiphaluka esifutshane, siya kuchaphazela ngokuthe ngqo ukuzinza nokuthembeka kweemveliso.
Isithuba, umgama phakathi kwemveliso yesixhobo mkhulu, ngaphambi kokuba ungabikho ngoku ukuchaneka, i-miniaturization, ngoko ngamanye amaxesha i-residu ayinayo impembelelo enkulu, ikhokelela ekubeni abantu bangabikho ingqwalasela eyaneleyo kwi-PCBA yokucoca, ngoku iimveliso zincinci kwaye zincinci, ukuchaneka kuphezulu kwaye ngaphezulu, umgama phakathi kwamacandelo uyanda kwaye uncinci, uphezulu ngokubanzi kwimfuno yendibano ye-PCBA, kwixa elidlulileyo intsalela engahoywayo ukuphembelela uzinzo kunye nokuthembeka kweemveliso ezininzi ngoku.
Ke ngoko, ukucocwa kwePCBA yinxalenye ebalulekileyo ekufuneka yenziwe.Ngokukodwa, kufuneka ihlanjululwe ngokukhawuleza emva kokuba i-welding igqityiwe, kuba ii-residues ze-flux ziya kuba nzima ngokuthe ngcembe ngokuhamba kwexesha kwaye zenze i-corrosion.Ngaphandle koko, izixhobo zokucoca ezahlukeneyo kunye nezikim zokucoca kufuneka zamkelwe ngokweemfuno zamanqanaba ahlukeneyo okucoca.
