Okokuqala, ngithanda ukwethula yethuPCB ihlanzekileumshinifuthiumshini wokuhlanza wensimbi:
Umshini wokuhlanza i-PCB umshini wokuhlanza i-brush roller uhlobo olulodwa.Isetshenziswa phakathi kwe-loader neUkuphrinta nge-stencilumshini, elungele izidingo zokuhlanza ze-AI kanye ne-SMT, ingafinyelela izidingo zezidingo zokuhlanza ezisezingeni eliphezulu kakhulu.
Umshini wokuhlanza wensimbiisetshenziselwa ukuhlanza insimbi yensimbi.
Kungani udinga ukuhlanzwa kwe-PCBA?Yiziphi izinzuzo?
Yonke i-PCBA ngesikhathi sokucutshungulwa, ikakhulukazi inqubo yokushisela ubuchwepheshe, izoba ne-solder paste, i-solder, i-solder wire, izinsalela ze-flux, izinsalela ku-PCBA layout zizokwakha imithombo eyinhloko yokungcola, insalela uma ingahlanzekile, ingabangela ukugqwala. isifunda, isifunda esifushane, sizothinta ngokuqondile ukuzinza nokuthembeka kwemikhiqizo.
Isikhala, ibanga phakathi komkhiqizo wedivayisi likhulu, ngaphambi kokungabi khona manje ukunemba okungaka, i-miniaturization, ngakho-ke ngezinye izikhathi izinsalela azizange zibe nethonya elikhulu, ziholela kubantu abanganaki ngokwanele ekuhlanzeni kwe-PCBA, manje imikhiqizo iyanda nakakhulu, ukunemba kuphakeme futhi ephakeme, ibanga eliphakathi kwezingxenye liya ngokuya lincane, inani eliphakeme kakhulu elidingekayo lokuhlangana kwe-PCBA, esikhathini esidlule izinsalela azinakwa ukuze zibe nomthelela ekuzinzeni nasekuthembekeni kwemikhiqizo eminingi manje.
Ngakho-ke, ukuhlanzwa kwe-PCBA kuyingxenye ebalulekile okufanele yenziwe.Ikakhulukazi, kufanele ihlanzwe ngokushesha ngangokunokwenzeka ngemuva kokuqedwa kwe-welding, ngoba izinsalela ze-flux zizoqina kancane kancane ngokuhamba kwesikhathi futhi zenze ukugqwala.Ngaphandle kwalokho, imishini yokuhlanza ehlukene kanye nezikimu zokuhlanza kufanele zamukelwe ngokuya ngezidingo zamazinga ahlukene okuhlanza.
