He ʻāpana koʻikoʻi loa ʻo Solder mast o nā papa kaapuni paʻi PCB, ʻaʻohe kānalua e kōkua ʻo Solder mask i ka hui ʻana, akā he aha nā mea ʻē aʻe e hāʻawi ai i ka solder mask?Pono mākou e ʻike hou aku e pili ana i ka solder mask iā ia iho.
He aha ka pale huna?
ʻO ka mask solder a i ʻole solder stop mask a i ʻole solder resistance he ʻāpana polimer like me ka lacquer i hoʻohana pinepine ʻia i nā ʻāpana keleawe o kahi papa kaapuni paʻi (PCB) no ka pale ʻana i ka hoʻoheheʻe ʻana a i mea e pale ai i nā alahaka solder mai ka hana ʻana ma waena o nā pad solder kokoke. .
ʻO ke alahaka solder kahi pilina uila i manaʻo ʻole ʻia ma waena o nā mea hoʻokele ʻelua ma ke ʻano o kahi puʻupuʻu solder.
Hoʻohana nā PCB i nā mask solder e pale aku i kēia.
ʻAʻole hoʻohana mau ʻia ka mask solder no nā hui i hoʻopaʻa ʻia i ka lima, akā pono ia no nā papa i hana nui ʻia i kūʻai ʻia me ka hoʻohana ʻana i nā ʻenehana reflow a i ʻole solder bath.
Ke hoʻohana ʻia, pono e hana ʻia nā puka i loko o ka solder mask ma nā wahi a pau e kūʻai ʻia ai nā ʻāpana, e hoʻokō ʻia me ka photolithography.
SHe ʻōmaʻomaʻo ka maka kahiko akā loaʻa i kēia manawa i nā kala he nui.
Ka hana o ka solder mask
ʻO ke kaʻina hana solder mask he mau ʻanuʻu.
Ma hope o ka hoʻomaʻemaʻe mua ʻana, kahi e hoʻomaʻemaʻe ʻia ai nā papa kaapuni i paʻi ʻia a ʻo ka ʻili keleawe ka hopena mechanically a i ʻole kemika, ua hoʻopili ʻia ka mask solder.
Nui nā noi e like me ka uhi ʻana i ka pale, ka paʻi pale a i ʻole ka uhi ʻana i loaʻa.
Ma hope o ka uhi ʻia ʻana o nā PCB me ka solder mask, pono e puhi ʻia ka mea hoʻoheheʻe ma kahi ʻanuʻu hoʻomaloʻo.
ʻO ka hana hou aʻe o ke kaʻina ka hoʻolaha.No ke kūkulu ʻana i ka mask solder, hoʻohana ʻia ka hana kiʻi.
E polymerize nā wahi i hōʻike ʻia aʻo nā wahi i uhi ʻia e noho monomer.
I ka hoʻomohala ʻana, ua kūpaʻa nā wahi i hōʻike ʻia, a e holoi ʻia nā wahi i ʻike ʻole ʻia (monomer).
Hana ʻia ka hoʻomaʻamaʻa hope ʻana i loko o ka umu a i ʻole ka tunnel.Ma hope o ka ho'ōla hope ʻana, pono paha kahi lāʻau UV hou no ka hoʻonui ʻana i nā waiwai mechanical a me nā kemika o ka mask solder.
ʻO ka hana nui o ka mask solder:
No laila he aha ka hana o kahi Solder Mask?
E koho i ʻelua ma waena o ka papa inoa:
1. Palekana mai ka oxidation.
2. Pale mai ka wela.
3. Palekana mai ka hoʻokuʻu ʻia ʻana o ka solder.
4. Palekana mai ka hoʻokuʻu electrostatic.
5. Ka pale ʻana mai ka hoʻokuʻu hyper o kēia manawa.
6. Pale mai ka lepo.
Ma waho aʻe o nā hana nui ma luna, aia kekahi mau noi ʻē aʻe.Inā he mau nīnau hou aʻe e pili ana i ka solder mask, e ʻoluʻolu e nīnau i nā loea ma PHILIFAST.
