Kufotokozera mwachidule
Filimu yabuluu ya PVC, tepi yabuluu yophimba imapangidwa ndi filimu ya PVC yokutidwa ndi guluu wapadera wa acrylic, yokhala ndi asidi ndi alkali yotsutsa, yokana dzimbiri, yopanda guluu wotsalira ikachotsedwa, ndi zina zotero. Mabodi oteteza ma PCB plating circuit ndi ma plating ndi soldering ena.

Palibe guluu wotsalira, kukana asidi ndi alkali, kukana kutentha kwambiri, kukana dzimbiri, palibe guluu wotsalira akachotsedwa, ndi zina zotero.
Kugwiritsa ntchito
Filimu yoteteza yabuluu yopangira ma circuit board, filimu yabuluu yopangira ma plating, filimu yoteteza mbiri, filimu yoteteza yolimbana ndi kutentha kwambiri, filimu yoteteza chitseko chachitetezo, filimu yoteteza chitseko ndi zenera, filimu yoteteza galasi, filimu yoteteza yabuluu yolimbana ndi asidi ndi alkali, filimu yabuluu yolimbana ndi dzimbiri ya asidi ndi alkali, tepi yabuluu yopangira ma plating, tepi yabuluu yopangira ma pinhole, tepi yoyesera ya spray plating. Imagwiritsidwa ntchito kwambiri popangira ma PCB board, kuti aletse kulowa kwa plating solution m'zigawo zamagetsi, kuti apewe kuipitsidwa kwa zigawo zopanda ntchito ndi madontho ndi nthunzi za plating solution, komanso kuphimba zigawo za terminal pamene zikuphimba pamwamba pa circuit; kuti atsimikizire kuti solder ikulimbana ndi solder, kukana kusungunuka ndi kutseka panthawi yopangira ma solder pamene akuphimba zigawo zamagetsi pa substrate.
Tepi yamagetsi ya PVC imapangidwa kuchokera ku filimu yofewa ya polyvinyl chloride (PVC) yokutidwa ndi guluu wothira mphamvu ya mphira, ndipo ndi yoyenera kulumikiza mawaya a magalimoto, kuzunguliza waya ndi kuteteza kutenthetsa. Tepi yamagetsi ya polyester, yomwe imadziwikanso kuti Mylar tape, imapangidwa ndi filimu ya polyester ndi guluu wothira mphamvu ya solvent, mphamvu yayikulu yogwira, kukana kutentha kwambiri, yomwe imagwiritsidwa ntchito popanga ma transformer osiyanasiyana. Tepi yothira mphamvu imatanthauza tepi yomwe imagwiritsidwa ntchito ndi akatswiri amagetsi kuti apewe kutayikira kwa magetsi ndipo imagwira ntchito yotetezera mphamvu. Imadziwikanso kuti tepi yothira mphamvu, tepi, ndi tepi yoyambira ndi guluu wothira mphamvu ya kupanikizika. Tepi yoyambira nthawi zambiri imapangidwa ndi thonje, nsalu yopangidwa ndi filimu ya pulasitiki, ndi zina zotero. Guluu wothira mphamvu umapangidwa ndi rabara komanso utomoni wothira mphamvu, ndi zina zotero, wokhala ndi kukhuthala kwabwino komanso mphamvu zabwino zotetezera mphamvu. Tepi yothira mphamvu imakhala ndi kukana kutenthetsa mphamvu, kuletsa moto, kukana nyengo ndi zina, yoyenera kulumikiza waya, kuteteza kutenthetsa mphamvu yamagetsi ndi zina.
