i-wave soldering

Wake wezwa nganiamanyela?Uma usebenzisa i-wave soldering ukuze uhlanganise ama-PCB, kungenzeka ukuthi ujwayelene kakhulu nalolu ngqimba oluyichunky lwensimbi oluqoqa ebusweni be-solder encibilikisiwe.Amanyela e-Solder akhiwa izinsimbi ezixutshwe ne-oxidized kanye nokungcola okwenzeka njengoba i-solder encibilikisiwe ithinta umoya kanye nendawo yokukhiqiza.Ngeshwa, le nqubo ivame ukuphumela ku-50% we-bar solder idliwe yi-solder dross.Kodwa lokho abantu abaningi abangakuqapheli ukuthi i-solder dross ingaphezu kuka-90% insimbi ebalulekile.Esikhathini esidlule, wawumane uqoqwe njengemfucumfucu futhi ulahlwe.Kodwa-ke, namuhla, thina kwa-Indium Corporation sikholelwa ukuthi inani lensimbi etholiwe kufanele libuyiselwe.Kungakho sinikeza izinhlelo ezimbili ezihlukene zokugaywa kabusha kwamanye ama-solder.Uhlelo lokuqala luhilela ukubuyisela udoti kadoti ukuze uthole ingxenye yenani layo lensimbi njengekhredithi.Inketho yesibili idala kakhulu.Ngalolu hlelo, usibuyisela amanyela kithi, bese siyiguqula ibe solder yebha esebenzisekayo ngaphakathi kwe-spec yasekuqaleni.Ukhokha kuphela imali yokucubungula, futhi uthola ukwaziswa okubalulekile nokusebenzisekayo ngokushintshanisa.Kungakhathalekile ukuthi yiluphi uhlelo olukhethayo, amanyela acwengisiswa ngogesi, futhi izinsimbi ezihlanzekile zitholwa futhi ziguqulelwe ku-bar solder esebenzisekayo.Eqinisweni, ezikhathini eziningi, le nsimbi egaywe kabusha inobumsulwa obungcono kakhulu kunensimbi emsulwa.Futhi akuwona nje amanyela angagaywa kabusha.Uma ushintshela ku-alloy ehlukile ngesikhathi se-wave soldering, yonke imbiza ye-solder izodinga ukuchithwa.I-alloy endala ingaqoqwa futhi igaywe kabusha, engakongela imali uma ushintshela ku-alloy entsha.Ukwengeza, i-bar solder nocingo okungazange kusetshenziswe phakathi nesikhathi seshelufu kungaphinda kusetshenziswe kabusha ukuze kubuyiselwe elinye inani lakhona.Kwa-Indium Corporation, sikholelwa ekwehliseni imfucuza kanye nokukhulisa izinsiza.Kungakho sizibophezele ekusizeni amakhasimende ethu ukuthi abuyise inani lamanye ama-solder nezinye izinto ezingasetshenzisiwe.Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nezinhlelo zethu zokugaya kabusha!
