Ezinsizeni zomhlangano we-PCB wokuma okukodwa, izici eziningi ezihilelekile, njengokukhiqizwa kwe-PCB, ukuthengwa kwengxenye, umhlangano wesifunda ophrintiwe, ukuhlola, njll. Ngezidingo eziphakeme zamakhono okukhiqiza okuthambile emikhiqizo ye-elekthronikhi, izidingo zokukhiqiza eziphakeme kakhulu.Abakhiqizi bomhlangano we-elekthronikhi kudingeka ukuthi banake kakhulu ukuphathwa kwekhwalithi yokucubungula kwe-PCBA.I-PCBFuture ikwethulela amaphuzu ayisihluthulelo okuphathwa kwekhwalithi yokukhiqiza ngogesi kwe-PCBA.
Iphuzu elibalulekile 1: Ukukhiqizwa kwe-PCB
Kunezici eziningi ezinquma ikhwalithi ye-PCB, phakathi kwazo okubalulekile kwe-substrate, ukulawulwa kokukhiqiza, nogqinsi lwethusi okuyizinto ezibaluleke kakhulu.Lapho ukhetha ifektri ye-PCB, akufanele unake kuphela inani layo, kodwa futhi unake lawa maphuzu abalulekile ekhwalithi.Amabanga wezinto ezingaphansi komhlaba asukela ku-A kuye ku-C, futhi amanani ayahluka kakhulu.Ukuphathwa kwekhwalithi okuphelele kanye nezinsizakalo zobuchwepheshe ezichwepheshile kuzoba nomthelela omkhulu kukhwalithi ye-PCB.
Iphuzu elisemqoka 2: Ukuthengwa kwezingxenye
Qinisekisa ukuthi izingxenye ziphuma kumkhiqizo wangempela, okuwukhiye wenqubo yokupakisha, engavimbela ukonakala kwenqwaba emthonjeni.Umkhiqizi womhlangano we-elekthronikhi udinga ukusetha izindawo zokuhlola impahla engenayo (I-IQC, Ukulawulwa Kwekhwalithi Engenayo), ahlole ukuvumelana kwezinto ezingenayo, futhi asampula ukubukeka, amanani engxenye, amaphutha, njll. Umkhiqizi we-PCBA naye udinga ukuqhubeka nokwandisa ingxenye yakhe yamashaneli abahlinzeki. .
Iphuzu eliyisihluthulelo lesithathu: inqubo yokukhweza ngaphezulu
Enqubweni yokukhweza kwe-SMT chip processing surface, izinkampani ezikhiqiza izinto zikagesi ze-PCBA zidinga ukuqinisekisa ukufana nokuvumelana kokuphrinta kwe-solder paste, ukuhlela okunengqondo kwemishini ye-SMT, nokuqinisekisa isivuno sokubekwa kwe-IC ne-BGA enembayo.Ukuhlolwa kwe-100% kwe-AOI kanye nokuhlolwa kwekhwalithi yenqubo yokukhiqiza (IPQC, Ukulawulwa Kwekhwalithi Yenkambiso) kuyadingeka kakhulu.Ngesikhathi esifanayo, kuyadingeka ukuqinisa ukuphathwa kokuhlolwa komkhiqizo ophelile.
Iphuzu elingukhiye 4: Ukuhlolwa kwe-PCBA
Onjiniyela bemiklamo ngokuvamile bagcina amaphuzu okuhlola ku-PCB futhi banikeze izinhlelo zokuhlola ezihambisanayo kubakhiqizi bezinto zikagesi ezicubungula i-PCBA.Ezivivinyweni ze-ICT ne-FCT, amandla kagesi wesekethe namajika amanje ayahlaziywa, kanye nemiphumela yokuhlolwa kokusebenza komkhiqizo we-elekthronikhi (mhlawumbe namanye amafreyimu okuhlola) , bese kuqhathaniswa nezinhlelo zokuhlola ukuze kutholwe isikhawu sokwamukela, esibuye sibe lula. ukuze amakhasimende aqhubeke nokuthuthuka.
Iphuzu elibalulekile lesihlanu: ukuphathwa kwabantu
Ezinkampanini ezikhiqiza izinto zikagesi ze-PCBA, imishini esezingeni eliphezulu iyingxenye encane yayo, futhi into ebaluleke kakhulu ukuphathwa kwabantu.Okubaluleke kakhulu ukuthi abaphathi bokukhiqiza bakha izinqubo zokulawulwa kokukhiqizwa kwesayensi futhi baqondise ukuqaliswa kwesiteshi ngasinye.
Emqhudelwaneni oshubile wemakethe, izinkampani ezikhiqiza ama-elekthronikhi ziyaqhubeka nokwandisa amandla azo angaphakathi futhi zicolise ukuphathwa kwazo kokukhiqiza kuwukhiye wokuqhubeka nokuzivumelanisa nezimakethe.Ukulawulwa kwekhwalithi kanye nensizakalo yokukhiqiza kuzoba umugqa wempilo wokuncintisana.
