1. Operation matanho ewave soldering muchina.
1).Wave soldering midziyokugadzirira kusati kwapisa
Tarisa kuti PCB inotengeswa yakanyorova here, kana majoini ekutengesa akaiswa oxidized, akaremara, nezvimwewo;iyo flux yakabatana neiyo nozzle interface ye sprayer.
2).Kutanga-up of wave soldering equipment
Rongedza hupamhi hwewave soldering muchina dhiraivha bhandi (kana gadziriso) zvinoenderana nehupamhi hweiyo yakadhindwa redunhu bhodhi;batidza simba uye basa reimwe neimwe fan yemuchina wekutengesa wave.
3).Isa iyo welding paramita yewave soldering midziyo
Flux Flow: Zvichienderana nekuti iyo flux inobata sei pasi pePCB.Iyo flux inodiwa kuti inyatso kupfekedzwa pazasi pePCB.Kutanga kubva paburi repaPCB, panofanira kunge paine kakuyerera kadiki pamusoro peburi neburi rinopinda kubva nepaburi kuenda padhi, asi risingapinde.
Preheating tembiricha: set zvinoenderana nemamiriro chaiwo eiyo microwave oven preheating zone (tembiricha chaiyo iri pamusoro pePCB inowanzoitika 90-130 ° C, tembiricha yendiro gobvu ndiyo muganho wepamusoro webhodhi rakaunganidzwa rine zvakawanda. SMD components, uye tembiricha inokwira mutsetse ishoma pane kana kuenzana ne2°C/S;
Conveyor bhandi kumhanya: zvinoenderana akasiyana wave soldering michina uye PCB marongero kuti solder (kazhinji 0.8-1.60m/min);solder tembiricha: (inofanira kunge iri chaiyo tembiricha yepamusoro inoratidzwa pachiridzwa (SN-Ag-Cu 260±5℃, SN-Cu 265±5°C). Sezvo tembiricha sensor iri mubhati retani, tembiricha yemamita. kana LCD inenge 3 ° C yakakwirira kudarika chaiyo yepamusoro tembiricha;
Peak urefu kuyerwa: kana ichipfuura pasi pePCB, gadzirisa kusvika 1/2 ~ 2/3 yePCB ukobvu;
Welding angle: kutapurirana kutenderera: 4.5-5.5 °;welding nguva: kazhinji 3-4 masekondi.
4).Chigadzirwa chacho chinofanirwa kutengeswa uye kuongororwa (mushure mezvese maparamendi emagetsi asvika pamutengo wakatarwa)
Zvinyoro isa bhodhi redunhu rakadhindwa pabhandi rekutakura (kana gadziriso), muchina unongomwaya mbabvu flux, preheats, wave solders uye inotonhorera;iyo yakadhindwa yedunhu bhodhi yakabatanidzwa pakubuda kweave soldering;maererano nechiyero chekuongorora fekitori.
5).Gadzirisa welding parameters zvinoenderana nePCB welding mhinduro
6).Ita kuenderera mberi kwekugadzira welding, batanidza iyo yakadhindwa yedunhu bhodhi pane inobuda wave soldering, isa mu-anti-static turnover bhokisi mushure mekuongorora, uye tumira bhodhi rekuchengetedza kuti rizogadziriswa rinotevera;panguva yekuenderera mberi kwekugadzirisa, bhodhi rimwe nerimwe rakadhindwa rinofanira kuongororwa, uye kukanganisa kwemagetsi Mabhodhi akadhindwa akanyanya anofanira kutengeswa zvakare pakarepo.Kana pachine zvikanganiso mushure mekuputika, chikonzero chinofanira kuonekwa, uye kusungirirwa kunofanira kuenderera mberi mushure mekugadzirisa maitiro ekugadzirisa.
2. Mapoinzi ekutarisisa mune wave soldering oparesheni.
1).Usati wave soldering, tarisa mamiriro ekushanda kwemidziyo, kunaka kwebhodhi redunhu rakadhindwa rinotengeswa uye chimiro cheplug-in.
2).Mukati mekugadzira wave soldering, iwe unofanirwa kugara uchiteerera kushanda kwemidziyo, kuchenesa maokisi ari pamusoro pebhati yekugezesa nekufamba kwenguva, wedzera polyphenylene ether kana sesame mafuta uye mamwe ma antioxidants, uye wozadza solder nenguva.
3).Mushure mekunge wave soldering, iyo welding mhando inofanirwa kutariswa block ne block.Kune nhamba diki yekushaikwa kwekutengesa uye bridging soldering point, manual kugadzirisa welding inofanira kuitwa nenguva.Kana paine huwandu hukuru hwematambudziko emhando yewelding, tsvaga zvikonzero nenguva.
Wave soldering inyanzvi yekugadzira maindasitiri.Nekudaro, nehuwandu hukuru hwemashandisirwo ezvivakwa zvepamhepo, iyo yakasanganiswa yekubatanidza plug-in components uye pamusoro pekumusoro mount components zvakaunganidzwa padunhu redunhu panguva imwe chete yave yakajairika fomu yekusangana muzvigadzirwa zvemagetsi, nekudaro ichipa mamwe maitiro paramita. kune wave soldering tekinoroji.Kuti zvizadzise zvinodiwa zvakasimba, vanhu vachiri kugara vachitsvaga nzira dzekuvandudza kushambadzira kwehutano hwemafungu ekutengesa, kusanganisira: kusimbisa hutano hwehutano hwezvinyorwa zvakadhindwa zvebhodhi rekugadzira uye zvikamu zvisati zvaitika;kuvandudza zvinhu zvekugadzirisa zvakadai sekuyerera uye solder Quality control;panguva welding process, optimize maitiro paramita senge preheating tembiricha, welding track inclination, wave urefu, welding tembiricha uye zvichingodaro.
