Malangizo ogwiritsira ntchito makina opangira reflow soldering

Reflow uvuninjira zogwirira ntchito

1. Onetsetsani kuti pali zinyalala mkati mwa zipangizo, chitani ntchito yabwino yoyeretsa, kuti muteteze chitetezo, yatsani makina, sankhani pulogalamu yopangira kuti mutsegule zokonda kutentha.

2. Reflow uvuni kalozera kalozera m'lifupi kusinthidwa malinga ndi m'lifupi mwa PCB, kutsegula mayendedwe mphepo, mauna lamba zoyendera, ozizira zimakupiza.

3. Makina opangira zitsuloKuwongolera kutentha kumakhala ndi kutsogolera kwakukulu (245 ± 5) ℃, mankhwala otsogolera malata a ng'anjo yamoto (255 ± 5) ℃, kutentha kwa kutentha: 80 ℃ ~ 110 ℃.Malinga ndi magawo operekedwa ndi njira yopangira kuwotcherera mosamalitsa komanso mwamphamvu kuwongolera magawo a makina apakompyuta, lembani magawo amakina obwereza pa nthawi yake tsiku lililonse.

4. kuti motsatizana kuyatsa lophimba kutentha, kukhala kutentha kwa kutentha anapereka pamene inu mukhoza kuyamba pa, PCB, bolodi, pa bolodi kulabadira malangizo.Onetsetsani kuti mtunda pakati pa 2 motsatizana matabwa a conveyor lamba ndi osachepera 10mm.

5. The reflow soldering conveyor lamba m'lifupi kusintha kwa malo oyenera, m'lifupi lamba conveyor ndi flatness ndi bolodi mzere, fufuzani zinthu kuti kukonzedwa mtanda nambala ndi zogwirizana zofunika luso.

6. Small reflow soldering makina sadzakhala yaitali kwambiri, kutentha kwambiri chifukwa cha chodabwitsa cha matuza mkuwa platinamu;zolumikizira solder ayenera kukhala yosalala ndi yowala, bolodi dera ayenera onse ziyangoyango pa malata;mizere yosagulitsidwa bwino iyenera kubwerezedwanso, kubwereza kwachiwiri kudzachitika mutatha kuzirala

7. kuvala magolovesi kukatenga solder PCB, kokha kukhudza m'mphepete mwa PCB, zitsanzo 10 zitsanzo pa ola, fufuzani mkhalidwe woipa, ndi mbiri deta.Panthawi yopanga, ngati muwona kuti magawowo sangathe kukwaniritsa zofunikira zopangira, simungathe kusintha magawowo nokha, muyenera kudziwitsa katswiri kuti athane nawo.

8. Yezerani kutentha: plug sensor mu socket yolandila yoyesa, yatsani chosinthira mphamvu ya tester, ikani choyesa mkati mwa solder ya reflow ndi bolodi lakale la PCB pamwamba pa solder reflow, chotsani tester ndi kompyuta kuti muwerenge. deta kutentha olembedwa pa reflow soldering ndondomeko, ndiko kuti, deta choyambirira kwa reflow soldering makina kutentha pamapindikira.

9. Adzakhala atagulitsa bolodi molingana ndi nambala imodzi, dzina, ndi zina.Pofuna kupewa kusakaniza zipangizo kubala zoipa.

Reflow soldering ng'anjo ntchito zodzitetezera

1. Musakhudze lamba wa mesh panthawi ya ntchito ndipo musalole kuti madzi kapena mafuta alowe mu ng'anjo kuti asapse.

2. Ntchito zowotcherera ziyenera kuonetsetsa mpweya wabwino, kuteteza kuwonongeka kwa mpweya, ogwira ntchito ayenera kuvala zovala zantchito zabwino, kuvala chigoba chabwino.

3. Nthawi zambiri yesani kutentha kwa waya, kuti mupewe kutayika kwa ukalamba.
