Hongu, conformal coating inogona kubviswa nezvinonyungudutsa kana maturusi. Acrylic coatings inobuda nyore, ichiita kugadzirisa kuve nyore. Silicone uye parylene coatings zvakaoma kubvisa asi zvakadaro zvinogoneka. Izvi zvinoita kuti conformal coating ive yakanaka kune inogaro gadziridzwa.
3. Kubika hari kwakanakira michina inoita kupisa kwakawanda here?
Potting inodzivirira zvakanaka asi inoteya kupisa, izvo zvinogona kukuvadza zvishandiso. Kana PCB yako ichipisa zvakanyanya, conformal coating iri nani. Inobvumira kupisa kutiza apo ichichengetedza bhodhi.
4. Ndeipi sarudzo inodhura zvishoma?
Conformal coating yakachipa nekuti inoshandisa zvinhu zvishoma uye inoshanda nekukurumidza. Potting inodhura zvakanyanya sezvo yakakora uye inotora nguva yakareba kuisa. Nekuchengetedza mari, conformal coating ndiyo yakanakisa sarudzo.
5. Ndinogona kushandisa zvese zviri zviviri zvakaringana coating uye hari pamwechete?
Ehe, unogona kusanganisa nzira mbiri dzekudzivirira zvirinani. Shandisa potting yezvikamu zvakatarisana nekudengenyeka kana makemikari. Isa conformal coating kunzvimbo dzakareruka. Izvi zvinopa kuenzana kwesimba uye kushanduka.
