ʻO ka PCB e pili ana i ka papa kaapuni paʻi (Printed circuit board), ʻo ia ka mea nāna e hoʻolako i ka pilina uila o nā mea uila.He mea maʻamau ia i ka ʻoihana uila, a ʻekolu anti-adhesive (pena) i hoʻohana nui ʻia i loko o ia mea, ʻaʻohe ʻano ʻano hoʻopili e like me ka PCB ʻekolu-hōʻoia adhesive (pena).ʻO ka ʻoiaʻiʻo, ua uhi ʻia kahi papa o ʻekolu-hōʻoia adhesive (pena) ma ka PCB.pena).
ʻO ka hoʻohana ʻana i ʻekolu anti-paints e pale i ka PCB mai ka pōʻino ʻia e nā kumu o waho a hoʻomaikaʻi i ke ola lawelawe o ka PCB.No ka mea, ʻoi aku ka kiʻekiʻe o nā huahana uila kiʻekiʻe a kiʻekiʻe aʻe no ka maikaʻi o ka PCB, hoʻohana nui ʻia nā uhi conformal ma nā papa kaapuni.
Nā kumu e hoʻopilikia maʻalahi i ka PCB:
ʻO ka wai ka mea nui loa a luku loa i nā PCB.ʻO ka nui o ka makū e hoʻemi nui i ka pale ʻana i waena o nā conductors, e hoʻolalelale i ka decomposition, e hōʻemi i ka waiwai Q, a me nā conductors corrode.Loaʻa pinepine ka ʻāpana metala o ka PCB i kahi patina, ka mea i hana ʻia e ka hopena kemika o ke keleawe metala me ka wai a me ka oxygen.
E like me ka hoʻopōʻino ʻana i nā haneli o nā mea haumia hiki iā ʻoe ke loaʻa ma ka papa kaapuni i paʻi ʻia, a hiki iā lākou ke hoʻoulu i nā hopena like me ka hoʻouka ʻana i ka wai, e like me ka pau ʻole o ka uila, ka ʻino o nā conductors, a me nā pōkole pōkole.ʻO nā mea haumia i loaʻa pinepine i nā ʻōnaehana uila he mau mea kemika i koe mai ka hana hana.ʻO kēia mau mea hoʻohaumia ʻo ia nā fluxes, nā mea hoʻokuʻu solvent, nā ʻāpana metala, a me nā inika māka.
Aia kekahi hui nui o ka haumia i hana ʻia e nā lima kanaka, e like me ka aila kino, nā manamana lima, nā mea hoʻonaninani a me nā koena meaʻai.Nui nō hoʻi nā mea haumia i loko o ke kaiapuni hana, e like me ka paʻakai paʻakai, ke one, ka wahie, ka waikawa, ka mahu corrosive a me ka mold.
No ke aha e hoʻohana ai i ʻekolu anti-adhesive (pena)?
ʻO ka PCB i uhi ʻia me ʻekolu anti-adhesive (pena) ʻaʻole wale ka moisture-proof, ka lepo-hōʻoia, a me ka wai ʻole, akā he kūʻē nō hoʻi i ke anuanu a me ka haʻalulu wela, ke kūpaʻa ʻelemakule, ka pale ʻana i ka radiation, ka paʻakai paʻakai kūʻē, ka ozone corrosion resistance, vibration ke kū'ē, ka loli maikaʻi a me ka pili ikaika.Ke hoʻopilikia ʻia e nā mea ʻino o ke kaiapuni hana, hiki iā ia ke hōʻemi a hoʻopau paha i ka hōʻemi ʻana o ka hana hana uila.
Ma muli o nā kaiapuni noi like ʻole o nā huahana hopena like ʻole, e koʻikoʻi ʻia nā koi hana no ka conformal adhesive.ʻO nā mea hana hale e like me nā pahu hau, nā mīkini holoi, a me nā mea hoʻomehana wai he mau koi kiʻekiʻe no ka pale ʻana i ka makū, ʻoiai nā mea pā waho a me nā kukui alanui e koi i nā huahana me ka hana anti-fog maikaʻi loa.
Pehea e hoʻopili koke ai i ka conformal adhesive (pena) i ka PCB?
I loko o ka ʻoihana hana PCB, aia kahi lako pono piha no ka uhi ʻana i ka pena pale ma nā papa kaapuni - ʻekolu mau mīkini pale anti-paint, ʻike ʻia hoʻi ʻekolu mau mīkini pale anti-paint, ʻekolu anti-paint sprayers, ʻekolu anti-paint sprayers. , ekolu anti-paint Paint spraying machines, etc., ua hoʻolālā ʻia e hoʻomalu i ka wai, a uhi i kahi ʻāpana o ka pena conformal ma ka ʻili o ka PCB, e like me ka uhi ʻana i kahi papa photoresist ma ka ʻili o ka PCB ma ke kuʻi ʻana, ka pīpī ʻana. a i ʻole ka wili wili.
Hoʻohana nui ʻia ka mīkini pale anti-paint ʻekolu no ka pīpī pololei ʻana, ka uhi ʻana a me ka hoʻoheheʻe ʻana o ke kāpili, ka pena a me nā wai ʻē aʻe i ke kaʻina huahana i ke kūlana kūpono o kēlā me kēia huahana, a hiki ke hoʻohana ʻia e hoʻokō i ke kaha kiʻi laina, pōʻai a i ʻole arc.
ʻO ka mīkini hoʻopiʻi anti-paint ʻekolu he mea hoʻoheheʻe i hoʻolālā kūikawā ʻia no ka pīpī ʻana i ʻekolu anti-pena.No ka mea he ʻokoʻa nā mea e hoʻoheheʻe ʻia a me nā wai hoʻoheheʻe e hoʻopili ʻia, ʻokoʻa nā ʻāpana koho o ka mīkini uhi e pili ana i ke ʻano o nā mea hana.Hoʻohana ka mīkini pale anti-paint ʻekolu i ka polokalamu hoʻomalu kamepiula hou loa, hiki ke hoʻomaopopo i ka pilina axis ʻekolu, a ua hoʻolako ʻia me ka ʻōnaehana hoʻonohonoho kiʻi kiʻi kiʻi e hiki ke hoʻomalu pono i ka wahi hoʻoheheʻe.
