Kwimveliso yebhodi yesekethe, ibhulorho yeoli eluhlaza ikwabizwa ngokuba yi-solder mask bhulorho kunye nedama lemaski le-solder. "Ibhendi yodwa" eyenziwe yifektri yebhodi yesiphaluka ukukhusela isiphaluka esifutshane sezikhonkwane zamacandelo e-SMD. Ukuba ufuna ukulawula ibhodi ethambileyo ye-FPC (ibhodi yesekethe eguquguqukayo ye-FPC) ibhulorho yeoli eluhlaza, kufuneka uyilawule ngexesha lenkqubo yemaski ye-solder. Kukho iindidi ezimbini zeFPC soft board solder mask materials: inki kunye nefilimu yokugquma.
Indima ye-FPC yebhodi yesekethe eguquguqukayo yemaski ye-solder
1. Ukugqunywa komphezulu;
2. Khusela umgca ukunqanda amanxeba emigca;
3. Thintela i-conductive foreign matter ukuba ingaweli kwisekethe kwaye ibangele i-short circuit.
I-inki esetyenziselwa ukuxhathisa i-solder idla ngokuba yi-photosensitive, ebizwa ngokuba yi-inki eyi-photosensitive inki. Ngokubanzi kukho eluhlaza, emnyama, emhlophe, ebomvu, emthubi, eluhlaza okwesibhakabhaka, njl njl. Ifilimu yekhava, ngokubanzi ityheli, emnyama namhlophe. Umnyama uneempawu ezintle ze-shading kwaye umhlophe unokubonakala okuphezulu. Inokuthi ithathe indawo yeoli emhlophe emnyama kwiibhodi ezithambileyo ze-FPC (iibhodi zesekethe eziguquguqukayo ze-FPC). Ibhodi ethambileyo ye-FPC (ibhodi yesekethe ye-FPC eguquguqukayo) ingasetyenziselwa imaski ye-inki ye-solder okanye imaski yokugubungela ifilimu.
