Ma ka papa hana kaapuni, ua kapa ʻia ke alahaka ʻaila ʻōmaʻomaʻo ʻo ka solder mask bridge a me ka solder mask dam. He "hui hoʻokaʻawale" i hana ʻia e ka hale hana papa kaapuni no ka pale ʻana i ka pōkole pōkole o nā pine o nā mea SMD. Inā makemake ʻoe e hoʻomalu i ka papa palupalu FPC (FPC flexible circuit board) alahaka ʻaila ʻōmaʻomaʻo, pono ʻoe e hoʻomalu iā ia i ka wā o ke kaʻina hana solder mask. ʻElua ʻano o ka FPC soft board solder mask material: inika a me ka uhi kiʻiʻoniʻoni.

ʻO ke kuleana o ka FPC flexible circuit board solder mask

1. Hoʻopili i ka ʻili;

2. E pale i ka laina no ka pale ʻana i nā ʻōpala laina;

3. Kāohi i ka hāʻule ʻana o nā mea ʻē aʻe i loko o ke kaapuni a hoʻopōkole.

ʻO ka ʻīnika i hoʻohana ʻia no ka pale kūʻai ʻana he photosensitive maʻamau, i kapa ʻia ka inika photosensitive wai. ʻO ka maʻamau he ʻōmaʻomaʻo, ʻeleʻele, keʻokeʻo, ʻulaʻula, melemele, uliuli, etc. ʻO ka ʻeleʻele maikaʻi nā waiwai o ka malu a me ke keʻokeʻo he kiʻekiʻe ka reflectivity. Hiki iā ia ke hoʻololi i ka aila ʻeleʻele keʻokeʻo no ka backlight FPC papa palupalu (FPC flexible circuit boards). Hiki ke hoʻohana ʻia ka papa ʻoluʻolu FPC (FPC flexible circuit board) no ka ʻīnika solder mask a i ʻole ka uhi ʻana i ke kiʻiʻoniʻoni solder mask.
