Mafekitori mazhinji ezvemagetsi anofunga kuti kutenga muchina muhombe reflow soldering unogona kuzadzisa zvinodiwa nekuita, asi kazhinji kunodhura mari yakawanda uye kupa nzvimbo inogarwa.8 kusvika 10 zone reflow uye nekukurumidza bhandi rinomhanya rinogona kunge riri mhinduro yakanakisa munzvimbo yepamusoro yekugadzira vhoriyamu, asi ruzivo rwedu rwakaratidza kuti madiki, akareruka, anotengeka 4 kusvika 6 zone modhi ndiyo yedu yepamusoro Mutengesi uye anoita basa rakanakisa. yekubata pick uye nzvimbo yekupinda, inosangana nevanotengesera paste vagadziri 'reflow yakatarwa, uye inopa yakavimbika, premium soldering performance.Asi ungava sei nechokwadi?Zvingani zvigadzirwa zvinogona 4-zone, 5-zone kana 6-zone reflow process kubata?Mamwe maverengero akareruka anoenderana nedhata yakapihwa solder paste uye vatengesi vemidziyo vanokupa yakanaka referensi.
Solder paste kudziyisa nguva
Chekutanga kutarisisa ndeye yako solder paste mugadziri akakurudzirwa kugadzirwa kwepaste formula yauchange uchishandisa.Vagadziri veSolder paste vanowanzopa zvakafara mahwindo nguva (maererano nenguva yekupisa) yezvikamu zvakasiyana-siyana zvereflow profile - 120 kusvika 240 seconds ye preheat uye soak nguva, uye 60 kusvika 120 seconds ye reflow nguva / nguva pamusoro pemvura.Tawana avhareji yekupisa nguva ye4 kusvika 4½ maminetsi (240-270 masekonzi) kuve yakanaka, inochengetedza fungidziro.Kune iyi yakapusa kuverenga, isu tinokurudzira kuti usatarise kutonhora kwema profiles akaiswa.Kutonhodza kwakakosha, asi kazhinji hakukanganise kunaka kwekutengesa kunze kwekunge PCB yakatonhodzwa nekukasira.
Kureba kwehovheni inopisa yekuyerera
Iyo inotevera yekufunga ndeye yakazara reflow yekudziya nguva, vangangoita vese vanogadzira reflow vanozopa reflow kupisa kureba, dzimwe nguva kunonzi kupisa tunnel urefu, mune yavo yakatarwa.Muchiverengero ichi chakareruka, isu tinongotarisa pane reflow nzvimbo uko kupisa kunoitika.
bhanhire rinomhanya
Pakuyerera kwega kwega kwauri kushandisa, patsanura kureba kwekupisa (mumainchi) nehuwandu hunokurudzirwa kupisa nguva (mumasekondi).Wowedzera nemasekonzi makumi matanhatu kuti uwane kumhanya kwebhandi mumainch paminiti.Semuenzaniso, kana yako solder kupisa nguva iri 240-270 masekonzi uye uri kufunga 6-zone reflow ine 80¾ inch tunnel, patsanura 80.7 inches ne240 uye 270 masekonzi.Yakapetwa nemasekonzi makumi matanhatu, izvi zvinokuudza kuti unofanirwa kuseta kumhanya kwebhandi reflow pakati pe17.9 inches paminiti uye 20.2 inches paminiti.Paunenge uchinge waona kukurumidza kwebhandi raunoda kune reflow yauri kufunga, iwe unofanirwa kuona huwandu hwepamusoro hwemabhodhi paminiti inogona kugadziriswa mune yega yega reflow.
Nhamba yepamusoro ye reflow plates paminiti
Tichifunga kuti pahukuru hwepamusoro iwe unofanirwa kurodha mabhodhi kupera-kusvika-kumagumo pane reflow oven's conveyor, zviri nyore kuverenga iyo yakawanda goho.Semuenzaniso, kana bhodhi rako rakareba masendimita manomwe uye kumhanya kwebhandi re6-zone reflow oven rinobva pa17.9 inches kusvika 20.2 inches paminiti, iyo yakanyanya kubuditswa yereflow i2.6 kusvika 2.9 mabhodhi paminiti.Izvi zvinoreva kuti, mabhodhi epamusoro uye ezasi edunhu achatengeswa mumasekonzi makumi maviri.
Ndeipi Reflow Oven Yakanakira Zvido Zvako
Pamusoro pezvikonzero zviri pamusoro apa, pane zvimwe zvakawanda zvinofanira kufungwa nezvazvo.Semuenzaniso, kugadzirwa kwemativi maviri-maviri kungangoda kuyererazve mativi ese echikamu chimwe chete, uye mashandisirwo emusangano wemaoko anogonawo kukanganisa kuti yakawanda sei reflow inodiwa.Kana gungano rako reSMT richikurumidza, asi mamwe maitiro ari kudzikamisa kubuda kwefekitori yako, saka iyo yakakura kuyerera yepasirese haina kunaka kwauri.Chimwe chinhu chekufunga nezvacho inguva yekuchinja kubva pane chimwe chigadzirwa kuenda kune chimwe.Zvinotora nguva yakareba sei kuti tembiricha yekuyerera igadzikane kana ichichinja kubva pane imwe gadziriso kuenda kune imwe?Pane zvinhu zvakawanda zvakasiyana zvekufunga nezvazvo.
Chengyuan Indasitiri yanga yakatarisana nereflow soldering, wave soldering, uye michina yekupotera kweanopfuura makore gumi.Tikugashirei kubata Chengyuan mainjiniya kuti usarudze iyo yakanyanya kufanira reflow soldering yako.
