PCB screen kudhinda chinhu chakakosha chinongedzo muPCB kugadzira maitiro, saka, ndedzipi zvikanganiso zvakajairika zvePCB board screen printing?

1, Chidzitiro chikamu chekukanganisa

1), kuvhara maburi

Zvikonzero zvemhando iyi yemamiriro ezvinhu ndeizvi: kudhinda kuoma nekukurumidza, mushanduro yevhezheni gomba rakaoma, kumhanya kwekudhinda kunokurumidza, simba rekukwenya rakanyanya. Solution, inofanira kushandisa volatile slow organic solvent printing material, ine jira rakapfava rakanyikwa muorganic solvent zvinyoro nyoro kuchenesa sikirini.

2), screen vhezheni inki kuvuza

Zvikonzero zvekutadza kwerudzi urwu ndezvi: PCB bhodhi repamusoro kana kudhinda zvinhu muguruva, tsvina, kukuvara kwescreen printing plate; Uye zvakare, pakugadzira ndiro, screen mask glue kuratidzwa hakuna kukwana, zvichikonzera kuti skrini mask yakaoma yakaoma haina kukwana, zvichikonzera kudonha kweinki. Mhinduro ndeyekushandisa tepi bepa kana tepi kunamira pane diki denderedzwa gomba rechiso, kana kuigadzirisa neglue yechidzitiro.

3), kukuvara kwescreen uye kuderedzwa chaiko

Kunyangwe kana mhando yechidzitiro yakanaka kwazvo, mushure menguva refu yekushandiswa, nekuda kwekukuvadzwa kweplate kukwesha uye kudhinda kukuvadzwa, kurongeka kwayo kuchaderedza zvishoma nezvishoma kana kukuvadza. Hupenyu hwesevhisi hwechidzitiro chekare hwakareba kupfuura iyo yeiyo isina kunanga skrini, kazhinji kutaura, kugadzirwa kwakawanda kweiyo skrini yekukurumidza.

4), kudhinda kumanikidzwa kunokonzerwa nekukanganisa

Scraper pressure yakakura zvikuru, kwete chete ichaita kuti zvinyorwa zvekudhinda zvive nehuwandu, zvichiita kuti scraper bending deformation, asi ichaita kuti zvinyorwa zvekudhinda zvive zvishoma, hazvigone kuvhara kudhinda mufananidzo wakajeka, zvicharamba zvichikonzera kukanganisa kwe scraper uye mask screen pasi. , kureba kwewaya mesh, deformation yemufananidzo

2, PCB yekudhinda layer yakakonzerwa nekukanganisa

1), kuvhara maburi

Iyo inodhinda zvinhu pachiratidziro inovhara chikamu cheiyo skrini mesh, ichitungamira kune chikamu chezvinyorwa zvekudhinda kuburikidza zvishoma kana kwete zvachose, zvichikonzera kutadza kurongedza kudhinda maitiro. Mhinduro yacho inofanira kunge iri yekuchenesa skrini nemazvo.

2), PCB bhodhi kumashure ine tsvina yekudhinda zvinhu

Nekuti iyo inodhinda polyurethane coating paPCB board haina kuoma zvachose, bhodhi rePCB rinoturikidzwa pamwe chete, zvichikonzera kuti zvinyorwa zvinonamira kuseri kwePCB board, zvichikonzera tsvina.

3). Kutadza kunamatira

Iyo yaimbova mhinduro yePCB board inokuvadza zvakanyanya kune bonding compressive simba, zvichikonzera kusabatana kwakashata; Kana kuti zvinhu zvinodhinda hazvienderani nemaitiro ekudhinda, zvichikonzera kusanamatira zvakanaka.

4), mashizha

Pane zvikonzero zvakawanda zvekunamatira: nekuti kudhinda zvinhu nekumanikidza kwekushanda uye kukuvadza kwekushisa kunokonzerwa nekunamatira; Kana kuti nekuda kwekushandurwa kwemazinga ekudhinda skrini, zvinyorwa zvekudhinda zvakakora zvakanyanya zvichikonzera kunamira mesh.

5). Ziso retsono nekutubwida

Dambudziko rePinhole ndechimwe chezvinhu zvakakosha zvekuongorora zvinhu mukutonga kwemhando.

Zvikonzero zvepinhole ndezvi:

a. Guruva netsvina pachiratidziro zvinotungamira kune pinhole;

b. PCB board surface yakasvibiswa nenharaunda;

c. Pane mabubbles mune inodhinda zvinhu.

Naizvozvo, kuita kunyatsoongorora chidzitiro, vakawana kuti ziso retsono pakarepo kugadzirisa.
