I. ʻO ka hui Rosin i hoʻokumu ʻia e nā kumu hana
1. Nalo solder paste
2. ʻAʻole lawa ka nui o ka solder paste i hoʻopili ʻia
3. Stencil, elemakule, ilihune leakage
II.ʻO ka hui Rosin i hoʻokumu ʻia e nā kumu PCB
1. Ua oxidized nā pads PCB a loaʻa ka solderability maikaʻi ʻole
2. Via puka ma nā pads
III.ʻO ka hui Rosin ma muli o nā mea ʻāpana
1. Deformation o nā pine ʻāpana
2. Oxidation o nā pine ʻāpana
IV.ʻO ka hui Rosin ma muli o nā mea hana
1. Holo wikiwiki ka mauna i ka hoʻouna ʻana a me ka hoʻonohonoho ʻana o ka PCB, a ʻo ka neʻe ʻana o nā ʻāpana kaumaha ke kumu o ka inertia nui.
2. ʻAʻole i ʻike ʻia e ka SPI solder paste detector a me AOI hoʻāʻo ʻana i nā pilikia e pili ana i ka hoʻopili solder paste i ka manawa.
ʻO ka hui V. Rosin ma muli o nā kumu hoʻolālā
1. 'A'ole like ka nui o ka pad a me ka pine component
2. ʻO ka hui ʻo Rosin i hana ʻia e nā puka metala ma ka pā
VI.ʻO ka hui Rosin ma muli o nā mea hoʻohana
1. ʻO ka hana maʻamau i ka PCB baking a me ka hoʻoili ke kumu o ka PCB deformation
2. Nā hana hewa i ka hui ʻana a me ka hoʻoili ʻana i nā huahana i hoʻopau ʻia
ʻO ke kumu, ʻo ia ke kumu o nā hui rosin i nā huahana i hoʻopau ʻia i ka hana PCB o nā mea hana SMT patch.Loaʻa i nā loulou like ʻole nā mea like ʻole o nā hui rosin.Aia ma ka ʻepekema wale nō, a ʻaʻole ʻike ʻia ma ka hoʻomaʻamaʻa.Inā loaʻa kekahi mea kūpono ʻole a i ʻole pololei, e leka uila iā mākou.
