Nekutevera nhanho idzi uye matipi, unogona kuve nechokwadi chekuti PCB yekupfeka inogara uye inochengeta bhodhi richishanda nemazvo.
Kubvisa machira ePCB anochinjika kunoda kuronga kwakanaka uye maturusi akakodzera. Unogona kusarudza nzira dzemakemikari, dzemakanika, dzekupisa, kana dzemicro-abrasive. Nzira chaiyo inoenderana nerudzi rwemachira. Kuziva hunhu hwemachira aya kunokubatsira kuwana mhedzisiro iri nani.
Gara Wakachengeteka : Pfeka zvipfeko zvekuchengetedza nguva dzose uye shanda munzvimbo ine mhepo inoyerera. Dzivirira PCB nekuyedza panzvimbo diki uye uchishandisa nzira dzakapfava.
Tarisa kukuvara mushure mekubvisa coating kuti PCB irambe ichishanda. Wedzera jasi idzva rinoenderana nezvinodiwa nebhodhi. Kugara uchiongorora uye kutarisirwa kuchaita kuti bhodhi rako rigare kwenguva refu. Tevera mazano aya kubata chero PCB chirongwa nechivimbo.
FAQ
Ndeipi nzira yakachengeteka yekubvisa PCB coatings?
Kubvisa kemikari kazhinji ndiyo yakachengeteka sarudzo. Shandisa zvinonyungudutsa senge isopropyl doro kune acrylic coatings. Gara uchiyedza solvent panzvimbo diki kutanga. Pfeka magirovhosi, magirazi uye shanda munzvimbo ine mhepo kuti ugare wakachengeteka.
Zvishandiso zvinogona kushandiswazve kune nzira dzakasiyana dzekubvisa?
Hongu, asi chenesa zvishandiso zvakanaka usati wachinja nzira. Semuyenzaniso, mabhurashi anoshandiswa pakubvisa makemikari anofanirwa kunge asina chasara musati mashandiswa. Izvi zvinodzivirira kusvibiswa uye zvinopa migumisiro iri nani.
Ungaziva sei kuti rudzii rwejasi rwuri paPCB?
Shandisa mwenje weUV kutarisa nzvimbo dzinopenya. Acrylic coatings inopenya pasi peUV mwenje. Kuti uwane mabhanhire akaomarara, bvunza mugadziri wePCB kana edza nzvimbo diki dzine zvinonyungudutsa kuti uone kuti dzinoita sei.
Kubvisa micro-abrasive kwakanaka kune ese machira?
Kwete, inoshanda zvakanyanya kune yakaoma machira senge epoxy kana parylene. Usashandise pazvinyoro zvakapfava senge acrylic, sezvo zvinogona kukuvadza PCB pamusoro. Sarudza iyo yakakodzera abrasive zvinhu zvichienderana nerudzi rwekupfeka.
Ko kana PCB ikakuvadzwa panguva yekubviswa?
Tarisa bhodhi pane zvakaputsika zvikamu kana zvikwenya. Gadzirisa zvidimbu zvakakanganisika usati wawedzera coating itsva. Shandisa maturusi emagetsi ekugadzirisa magetsi uye epoxy kune zvimiro zvekugadzirisa. Edza PCB mushure mekugadzirisa kuti uone kuti inoshanda nemazvo.
