Red glue maitiro:
Iyo SMT tsvuku glue process inotora mukana wekupisa kurapa zvimiro zveglue dzvuku, iyo inozadzwa pakati pemapadhi maviri nemuchina kana dispenser, yobva yaporeswa nechigamba uye reflow welding. Chekupedzisira, kuburikidza newave soldering, chete nzvimbo inokwira pamusoro peiyo wave crest, pasina kushandisa zvigadziriso kupedzisa iyo welding process.
SMT solder paste:
SMT solder paste process imhando yewelding process musurface mount tekinoroji, iyo inonyanya kushandiswa mukugadzira zvinhu zvemagetsi. SMT solder paste inoumbwa nesimbi yesimbi poda, inoyerera uye inonamira, iyo inogona kupa yakanaka welding performance uye inovimbisa kubatana kwakavimbika pakati pemidziyo yemagetsi uye yakadhindwa redunhu bhodhi (PCB).
Kushandiswa kwered glue process mu SMT:
1.Save Mutengo
Mukana wakakura weiyo SMT tsvuku glue process ndeyekuti hapana chikonzero chekugadzira zvigadziriso panguva yeave soldering, nokudaro kuderedza mutengo wekugadzira zvigadziriso. Naizvozvo, kuitira kuchengetedza mutengo, vamwe vatengi vanoisa maodha madiki vanowanzoda PCBA vanogadzira vanogadzira kuti vatore iyo tsvuku glue maitiro. Nekudaro, seyakarerekera kumashure welding process, PCBA yekugadzirisa zvidyarwa zvinowanzozeza kutora iyo tsvuku glue maitiro. Izvi zvinodaro nekuti iyo red glue process inoda kusangana nemamiriro chaiwo ekushandiswa, uye mhando yewelding haina kunaka senge solder paste welding process.
2.Chikamu saizi yakakura uye nzvimbo yakafaranuka
Mune wave soldering, rutivi rwechikamu-chakaiswa pamusoro-soro rinowanzosarudzwa pamusoro pecrest, uye rutivi rweplug-in riri pamusoro. Kana iyo yekumusoro yechikamu chechikamu saizi idiki, nzvimbo yacho yakatetepa, saka solder paste inobatanidzwa kana iyo peak ichiiswa, zvichikonzera kupfupika kwedunhu. Nokudaro, paunenge uchishandisa tsvuku yeglue process, zvakakosha kuve nechokwadi kuti ukuru hwezvikamu zvakakura zvakakwana, uye kuparadzanisa hakufaniri kuva kuduku.
SMT solder paste uye tsvuku glue process musiyano:
1. Process angle
Kana iyo nzira yekuparadzira ichishandiswa, iyo tsvuku glue ichava bhodhoro reiyo yese SMT chigamba chekugadzirisa mutsara mune mamwe mapoinzi; Kana iyo nzira yekudhinda inoshandiswa, inoda yekutanga AI uye ipapo chigamba, uye kunyatsojeka kwechinzvimbo chekudhinda chakanyanya kukwirira. Kusiyana neizvi, iyo solder paste process inoda kushandiswa kwemabhuraketi echoto.
2. Quality Angle
Glue tsvuku iri nyore kudonhedza zvikamu zvecylindrical kana vitreous mapakeji, uye pasi pesimba rekuchengetedza mamiriro, mahwendefa matsvuku erabha anonyanya kubatwa nehunyoro, zvichikonzera kurasikirwa kwezvikamu. Pamusoro pezvo, kana zvichienzaniswa nesolder paste, mwero wekuremara kwerabha dzvuku mushure mekutengesa wave wakakwira, uye matambudziko akajairika anosanganisira kushaikwa welding.
3. Mutengo wekugadzira
Iyo bhuraketi rechoto mune solder paste process imari yakakura, uye solder pane solder joint inodhura kupfuura solder paste. Kusiyana neizvi, glue mutengo wakakosha mune dzvuku glue process. Pakusarudza iyo tsvuku glue process kana solder paste process, anotevera masimboti anowanzo kuteverwa:
● Kana pane zvikamu zveSMT zvakawanda uye zvishoma zvishoma, vashandi vakawanda veSMT patch vanowanzoshandisa solder paste process, uye plug-in components inoshandisa post-processing welding;
● Kana pane zvimwe zvikamu zve-plug-in uye zvishoma zvishoma zveSMD, iyo tsvuku yeglue process inowanzo shandiswa, uye plug-in components zvakare post-processed uye welded. Hazvina mhosva kuti ndeipi nzira inoshandiswa, chinangwa ndechekuwedzera kugadzirwa. Zvisinei, zvakasiyana, iyo solder paste process ine yakaderera kuremara mwero, asi goho zvakare rakaderera.
Mune yakasanganiswa maitiro eSMT neDIP, kuitira kudzivirira iyo mbiri yevira mamiriro eimwe-side reflux uye wave crest, red glue inoiswa pachiuno cheiyo chip element pane wave crest welding pamusoro pePCB, kuitira kuti tini rigone kuiswa kamwe panguva yewave crest welding, kubvisa solder paste kudhinda maitiro.
Mukuwedzera, iyo glue tsvuku inowanzoita basa rakagadziriswa uye rekubatsira, uye solder paste ndiro basa rekugadzira. Red glue haifambisi magetsi, nepo solder paste ichiita. Panyaya yetembiricha yemuchina wekugezesa welding, tembiricha yeglue tsvuku yakadzikira, uye inodawo wave soldering kuti ipedze welding, nepo tembiricha yesolder paste yakakwira.
