Kudzora Kwakarurama Kwekupisa KweSMT Reflow Oven Kuti Uvandudze Hunhu Hwekushongedza
Dambudziko rekudzora tembiricha ye ovheni panguva yekugadzira? Iyi Standard Ichabatsira
Mukugadzirwa kweSMT (Surface Mount Technology), kururama kwekudzora tembiricha ye oven kunosarudza zvakananga kunaka kwe welding uye mashandiro ezvigadzirwa zvemagetsi. Kunyangwe kutsauka kudiki kunogona kutungamira kune zvikanganiso zvakaita se cold solder joints, voids, kana kukuvara kwezvikamu.
RICH FULL JOY Electronics, zvichibva paruzivo rwakakura mukugadzira PCBA nehunyanzvi hwehunyanzvi, yakagadzira "Reflow Oven Temperature Profile Setting Standard," ichipa gwara resainzi, rakarongeka, uye rinoshanda rekudzora tembiricha yeSMT reflow oven.
Pfupiso Yakajairika
Mutemo uyu unoshanda kune maovheni ese anodzokororwa muSMT workshop yedu, nemainjiniya eSMT vane hunyanzvi vane basa rekugadzirisa nekugadzirisa mapurofayiro etembiricha kuti vave nechokwadi chekuti tembiricha inodzorwa zvakanaka panguva yekunamira.
Kugadzirira Zvishandiso
Kuti muyere nemazvo uye muise mapurofayiri etembiricha, maturusi anotevera anodiwa: PROFILE tester, waya dzethermocouple, mabhodhi ePCB chaiwo ekuyera, magirovhosi ekudzivirira, uye zvirevo zve solder paste.
Kugadza Maitiro
1. Hwaro hweReference
Isa maparamita akaita se ramp-up rate, preheat temperature, uye reflow temperature zvichibva pane hunhu hwe solder paste dzakasiyana (semuenzaniso, lead-free, leaded solder pastes).
2. Hwaro hwekuyera
Mapurofayiri ekupisa anofanirwa kuyerwa pamabhodhi ePCB chaiwo kuti aratidze nemazvo mhedzisiro yenzvimbo chaiyo yekugadzira pakutamiswa kwekupisa.
3. Mitemo Yese
·Kukwira kwekukurumidza: 1–4℃/s
·Nzvimbo yekupisa: 150–200℃, 60–120s
·Nzvimbo yeKuyererazve: ≥220℃ kwemasekonzi 30–60
·Kupisa kwakanyanya: 235–250℃
·Kutonhora Kwemhepo:
4. Zvinodiwa Zvakakosha
Gadzirisa chimiro chako zvichienderana nemhinduro dzemhando yezvigadzirwa kana kuti nyatsotevedzera zvinodiwa nevatengi vako.
5.I-Glue Inorapa Maparamita
Tembiricha yekuchenesa glue yeI-glue i120℃, nenguva yekuchenesa iri pakati pemasekondi 90-150, uye muganho wepamusoro we170℃.
Zvekungwaririra
1. Kuedzwa kwezuva nezuva
Kuedzwa kweprofile yetembiricha yakazara kunofanirwa kuitwa uye kunyorwa mushure mekuchinja kwemagetsi kana tambo yekugadzira zuva nezuva.
2. Dare reMashandiro
Mainjiniya eSMT vane hunyanzvi chete ndivo vane mvumo yekugadzirisa marongero eprofile yetembiricha.
3. Kutevedzera Zvinodiwa Nevatengi
Gadza zvakasimba ma process parameters zvichienderana nezvinodiwa nemutengi zvekudzokorodza mashandiro.
4. Kugadzirisa Zvishandiso
Ita bvunzo dzemhepo inoyerera muovheni inodzokororwa mwedzi mitanhatu yega yega, uchivimbisa kushanda kwakasimba. Kusiyana kwekupisa pakati penzvimbo hakufanirwe kudarika 70℃.
Mhedziso
Nekushandisa "Reflow Oven Temperature Profile Setting Standard," RICH FULL JOY Electronics inoita kuti SMT welding ive yemhando yepamusoro, inovandudza kuvimbika kwekugadzirwa uye mashandiro echigadzirwa, uye inobatsira vatengi kukurumidzisa nguva yekuenda kumusika uye kuwana mabhenefiti emakwikwi.
