Mafakitole ambiri amagetsi amaganiza kuti kugula makina okulirapo owonjezera amatha kukwaniritsa zofunikira zonse, koma nthawi zambiri zimawononga ndalama zambiri ndikusiya malo omwe amakhala.8 mpaka 10 zone reflow ndi kuthamanga kwa lamba wothamanga kungakhale yankho labwino kwambiri pakupanga ma voliyumu apamwamba, koma zomwe takumana nazo zawonetsa kuti zing'onozing'ono, zosavuta, zotsika mtengo kwambiri za 4 mpaka 6 zone ndizogulitsa Apamwamba kwambiri ndipo zimagwira ntchito yabwino kwambiri. ya kusamalira pick ndi malo throughput, akukumana solder phala 'mapangidwe a reflow specifications, ndipo amapereka odalirika, umafunika soldering ntchito.Koma mungatsimikize bwanji?Ndi zinthu zingati zomwe 4-zone, 5-zone kapena 6-zone reflow process process ingagwire?Mawerengedwe ena osavuta otengera deta yoperekedwa ndi solder phala ndi ogulitsa zida adzakupatsani chidziwitso chabwino kwambiri.
Solder phala Kutentha nthawi
Chinthu choyamba kuganizira ndi solder phala Mlengi wanu analimbikitsa mapangidwe kwa phala mafotokozedwe mudzakhala ntchito.Opanga phala la solder nthawi zambiri amapereka nthawi zowoneka bwino zenera (potengera nthawi yonse yotentha) pamagawo osiyanasiyana amtundu wa reflow - 120 mpaka 240 masekondi a preheat ndi zilowerere nthawi, ndi 60 kwa 120 masekondi kwa reflow nthawi / nthawi pamwamba madzi madzi.Tapeza nthawi yotentha yokwana mphindi 4 mpaka 4½ (masekondi 240-270) kukhala kuyerekeza kwabwino, kosasintha.Pakuwerengera kosavuta uku, tikupangira kuti musanyalanyaze kuziziritsa kwa mbiri zowotcherera.Kuziziritsa ndikofunikira, koma nthawi zambiri sikungakhudze mtundu wa soldering pokhapokha PCB itakhazikika mwachangu.
Kutalika kwa ng'anjo yotenthetsera yotuluka
Kuganiziranso kotsatira ndi nthawi yonse yotenthetsera yotentha, pafupifupi onse opanga reflow amapereka kutalika kwa kutentha kwa reflow, nthawi zina amatchedwa kutenthetsa tunnel kutalika, muzofotokozera zawo.Muchiwerengero chophweka ichi, timangoganizira za malo obwereranso kumene kutentha kumachitika.
liwiro lamba
Pa kusefukiranso kulikonse komwe mukugwiritsa ntchito, gawani kutalika kwa kutentha (mu mainchesi) ndi nthawi yotentha yovomerezeka (mumasekondi).Kenako chulukitsani ndi masekondi 60 kuti mutenge liwiro la lamba mu mainchesi pamphindi.Mwachitsanzo, ngati nthawi yanu yotentha ya solder ndi masekondi 240-270 ndipo mukuganizira za 6-zone reflow ndi 80¾ inch tunnel, gawani mainchesi 80.7 ndi 240 ndi 270 masekondi.Kuchulukitsidwa ndi masekondi 60, izi zimakuuzani kuti muyenera kuyika liwiro la lamba wa reflow pakati pa mainchesi 17.9 pamphindi ndi mainchesi 20.2 pamphindi.Mukazindikira liwiro la lamba lomwe mukufuna kuti mufufuzenso momwe mukuganizira, muyenera kudziwa kuchuluka kwa matabwa pamphindi imodzi yomwe ingasinthidwe pakubweza kulikonse.
Chiwerengero chachikulu cha ma reflow plates pamphindi
Pongoganiza kuti pamlingo waukulu muyenera kukweza matabwa kumapeto mpaka kumapeto pa chotengera cha uvuni wa reflow, ndikosavuta kuwerengera zokolola zambiri.Mwachitsanzo, ngati bolodi lanu liri lalitali mainchesi 7 ndipo liwiro la lamba la 6-zone reflow oven limachokera pa mainchesi 17.9 mpaka 20.2 mainchesi pa mphindi, kutulutsa kwakukulu kwa kusefukirako ndi matabwa 2.6 mpaka 2.9 pamphindi.Izi zikutanthauza kuti, matabwa apamwamba ndi otsika adzagulitsidwa pafupifupi masekondi 20.
Ndi Reflow Oven Iti Yabwino Kwambiri Pazosowa Zanu
Kuphatikiza pazifukwa zili pamwambazi, palinso zinthu zina zambiri zofunika kuziganizira.Mwachitsanzo, kupanga mbali ziwiri kungafunike kubwezeretsanso mbali zonse ziwiri za gawo limodzi, ndipo ntchito zosonkhanitsa pamanja zingakhudzenso kuchuluka kwa mphamvu zobwezeretsanso zomwe zimafunikiradi.Ngati msonkhano wanu wa SMT uli wothamanga kwambiri, koma njira zina zimachepetsa kutulutsa kwa fakitale yanu, ndiye kuti kubwezanso kwakukulu padziko lonse lapansi sikuli kwabwino kwa inu.Chinthu china choyenera kuganizira ndi kusintha kwa nthawi kuchokera ku chinthu china kupita ku china.Zimatenga nthawi yayitali bwanji kuti kutentha kwa reflow kukhazikike pamene mukusintha kuchoka ku kasinthidwe kumodzi kupita kwina?Pali zinthu zambiri zosiyana zomwe muyenera kuziganizira.
Makampani a Chengyuan akhala akuyang'ana kwambiri pamagetsi owonjezera, kutenthetsa mafunde, ndi makina okutira kwazaka zopitilira khumi.Takulandilani kuti mulumikizane ndi mainjiniya a Chengyuan kuti akusankhileni zowotchera zoyenera kwambiri.
