Popanga ma board board, mlatho wamafuta obiriwira umatchedwanso solder mask bridge ndi solder mask dam. Ndi "gulu lodzipatula" lopangidwa ndi fakitale ya board board kuti ateteze kufupi kwa mapini a zigawo za SMD. Ngati mukufuna kulamulira FPC zofewa bolodi (FPC flexible dera bolodi) wobiriwira mafuta mlatho, muyenera kulamulira pa ndondomeko solder chigoba. Pali mitundu iwiri ya FPC soft board solder mask materials: inki ndi filimu yophimba.

Udindo wa FPC flexible circuit solder mask

1. Kutchinjiriza pamwamba;

2. Tetezani mzere kuti mupewe zipsera za mzere;

3. Kuletsa conductive zinthu zakunja kugwa mu dera ndi kuchititsa dera lalifupi.

Inki yomwe imagwiritsidwa ntchito popanga solder resistive nthawi zambiri imakhala ndi zithunzi, zomwe zimatchedwa inki yamadzimadzi ya photosensitive. Nthawi zambiri pali wobiriwira, wakuda, woyera, wofiira, wachikasu, buluu, etc. Chivundikiro filimu, zambiri chikasu, wakuda ndi woyera. Black imakhala ndi mithunzi yabwino komanso yoyera imakhala ndi mawonekedwe apamwamba. Itha kulowa m'malo mwamafuta oyera akuda kwa ma board a backlight FPC (FPC flexible circuit board). FPC soft board (FPC flexible circuit board) itha kugwiritsidwa ntchito ngati chigoba cha inki chogulitsira kapena chigoba chophimba filimu.
