Mazano ekushandisa kwakaringana reflow soldering muchina

Reflow ovhenioparesheni matanho

1. Tarisa kuti pane marara mukati memidziyo, ita basa rakanaka rekuchenesa, kuve nechokwadi chekuchengeteka, shandura muchina, sarudza purogiramu yekugadzira kuzarura zvigadziro zvekushisa.

2. Reflow oven guide width kuti igadziriswe maererano nehupamhi hwePCB, vhura mhepo yekufambisa, mesh bhandi rekutakura, kutonhora fan.

3. Reflow soldering muchinatembiricha yekudzora ine mutobvu wakakwira (245 ± 5) ℃, zvigadzirwa zvinotungamira tini tembiricha yekudzora tembiricha pa (255 ± 5) ℃, preheating tembiricha: 80 ℃ ~ 110 ℃.Zvinoenderana nemaparamita akapihwa neayo welding dhizaini dhizaini uye zvine hunyoro kudzora reflow muchina komputa paramita kuseta, rekodha reflow muchina paramita panguva zuva rega rega.

4. kuitira kutevedzana kuvhura tembiricha chinja, kuva tembiricha kune yakatarwa tembiricha apo unogona kutanga pamusoro, PCB, bhodhi, pamusoro bhodhi teererai nhungamiro.Ita shuwa kuti chinhambwe chiri pakati pemapuranga maviri akateedzana ebhandi rekutakura haasi pasi pe10mm.

5. The reflow soldering conveyor bhandi upamhi kugadziridzwa kuti zvakakodzera chinzvimbo, upamhi conveyor bhandi uye flatness uye mutsetse bhodhi, tarisa zvinhu kuti kugadziriswa batch nhamba uye chokuita unyanzvi zvinodiwa.

6. Diki reflow soldering machine haifaniri kurebesa, tembiricha yakanyanya kukonzerwa nechiitiko chemhangura platinum blistering;majoini e solder anofanira kunge akatsetseka uye akajeka, bhodhi redunhu rinofanira kunge riri mapedhi ese patin;mitsara isina kutengeswa zvakanaka inofanira kudzokororwa, yechipiri re-over ichaitwa mushure mekutonhodzwa

7. kupfeka magirovhosi kuti utore solder PCB, ingobata kumucheto kwePCB, sampling 10 samples paawa, tarisa mamiriro akaipa, uye rekodha data.Munguva yekugadzira, kana iwe ukaona kuti iyo parameter haigone kuzadzisa zvinodiwa zvekugadzira, iwe haugone kugadzirisa iyo parameter iwe pachako, iwe unofanirwa kukurumidza kuzivisa iyo technician kubata nayo.

8. Yera tembiricha: vhara sensor mushanduko mune socket yekugamuchira ye tester, vhura iyo tester simba switch, isa tester mukati me reflow solder neiyo yekare PCB board kumusoro pamusoro reflow solder, bvisa tester nekombuta kuti uverenge. iyo tembiricha data yakanyorwa panguva yereflow soldering process, kureva, iyo yepakutanga data yereflow soldering muchina tembiricha curve.

9. Ichave yakatengesa bhodhi maererano nenhamba imwe chete, zita, nezvimwe.Kuitira kudzivirira kusanganisa zvinhu kugadzira zvakaipa.

Reflow soldering oven operation precautions

1. Usagunzva bhandi remesh panguva yekushanda uye usabvumira mavara emvura kana mafuta kuti awire muchoto kudzivirira kupisa.

2. Welding mashandiro anofanirwa kuve nechokwadi chekufefetera, kudzivirira kusvibiswa kwemhepo, vashandisi vanofanirwa kupfeka hembe dzakanaka dzebasa, kupfeka mask yakanaka.

3. Kazhinji edza kudziyisa pawaya, kudzivirira kuchembera kuvuza.
