Nā ʻano o ka PCB Circuit Board Conformal Coating Materials For PCB assembly Manufacturing

Ka uhi ʻana o ka papa kaapuni conformal ʻo ia ke kaʻina hana o ka hoʻohana ʻana i nā papa resin kūikawā ma nā papa kaapuni e pale aku iā lākou mai nā mea ʻino ʻino. ʻO nā kiʻiʻoniʻoni polymeric he lahilahi a maʻalahi loa i hiki iā ʻoe ke ʻike i nā ʻāpana ma o ka papa, a ʻaʻole keakea ʻia ka hana o ka papa. Kōkua kēia kaʻina hana i ka pale ʻana i nā PCB koʻikoʻi mai ka hoʻopōʻino ʻana i ka haʻahaʻa, ka ʻino, nā kemika, nā wai, ka lepo, a me ka lepo.

ʻOi aku ka hilinaʻi a me ka lōʻihi o nā papa kaapuni i uhi ʻia no ka mea hiki ke hoʻohana ʻia i loko o nā kūlana koʻikoʻi me ka ʻole o ka pōʻino a pōkole paha. ʻOi aku ka ʻoluʻolu o nā mea hana a me nā mea hoʻohana me nā mea uila i uhi ʻia no ka mea ʻoi aku ka lōʻihi.

Nā mea hoʻopili conformal no PCB

Hoʻohana nā kaʻina hana kaʻa kaʻapuni i nā mea resin ʻokoʻa no ka loaʻa ʻana o nā hopena pale i makemake ʻia. ʻO ka mea nui, pono ke ʻano noi e hoʻoholo i ka mea i hoʻohana ʻia i ka uhi. ʻokoʻa nā ʻaʻahu conformal hāʻawi i nā waiwai like ʻole, a he mea nui e hoʻomaopopo mua i kāu mau mea hana a me kā lākou mau pono hana ma mua o ke koho ʻana i ka mea i kūpono loa. ʻO kekahi o nā mea maʻamau i hoʻohana ʻia i ka uhi ʻana i ka papa kaapuni:

ʻO ka resin polyurethane - Ua aloha ʻia nā resins Urethane no ko lākou kūʻē maikaʻi ʻana i nā kemika, abrasion, a me ka hoʻouka ʻana i ka wai. ʻO ia ka mea maʻamau i nā noi me nā mea i ʻike ʻia i nā wai corrosive a me nā mahu. Ma ka ʻaoʻao haʻahaʻa, ʻaʻole hiki ke pale i kēia ʻano uhi no laila paʻakikī ka hana hou ʻana a me ka wehe ʻana.

ʻO ka resin acrylic - ʻO kēia mau resins he polymers i hoʻoheheʻe ʻia. He maʻalahi lākou e hana hou a makemake i ka maloʻo maʻalahi. ʻO ia ka mea maikaʻi loa no nā papa kaapuni i ʻike ʻia i nā wahi haʻahaʻa. He mea maʻalahi ka wehe ʻana i nā uhi acrylic, e koho maikaʻi loa ia no nā hana hoʻoponopono. ʻAʻole kūpaʻa ka resin i nā mahu a me nā mea hoʻoheheʻe.

Eokixy resin - ʻO nā epoxies nā mea i hana ʻia e hana i kahi papa paʻakikī ma nā papa kaapuni. Kūleʻa ka papa i nā kemika, abrasion, a me ka haʻahaʻa a me ka liʻiliʻi loa. ʻOi aku ka maikaʻi o kēia ʻano uhi no nā papa kaapuni me nā haʻahaʻa haʻahaʻa haʻahaʻa o ke koʻikoʻi mechanical a me nā mea e pono e uhi pono ʻia me ka pale pale. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka paʻakikī o ka uhi ʻana, no laila paʻakikī ke hana hou a wehe.

Silika resine - Hiki nō hoʻi i ka uhi ʻana o ka papa kaapuni ke hoʻohana i ka resin silicone i maikaʻi loa i ka kemika, ka makū, ka wela, a me ka pale ʻana i ka corrosion. He maʻalahi kēia mea hoʻopili conformal a maʻalahi hoʻi e hana ma nā ʻano papa like ʻole. ʻO nā mea uila i ʻike nui ʻia i nā kaiapuni o waho ke kūpono loa no kēia uhi ʻana ma muli o ka loli mau ʻana o ka makū a me nā kūlana mahana. ʻO ke ʻano rubbery o ke silicone e hao i ka pale ʻana i ka abrasion akā hāʻawi pū kekahi iā ia i ka resilience i ke koʻikoʻi vibrational.

Parylene - Hoʻohana ʻia kēia uhi papa kaapuni me ka hoʻoheheʻe ʻana i ka mahu. Hoʻomaʻamaʻa ʻia ka mea i loko o ke ʻano kinoea a laila hoʻohui ʻia i loko o kahi ʻōpala e polymerize ia i loko o ke kiʻi ʻoniʻoni ʻoniʻoni i makemake ʻia a laila kau ʻia ma luna o nā papa. Loaʻa ka ikaika dielectric maikaʻi loa o ka kiʻiʻoniʻoni a kūpaʻa i nā wela kiʻekiʻe, ʻino, a me ka maʻa. ʻO ka hana hana kūikawā o kēia mea hoʻopili i mea paʻakikī a emiʻole ka kaulana. He mea paʻakikī hoʻi e wehe; Pono ka abrasion no ka wehe pono.

No ka ʻike hou aku e pili ana i nā ʻano pcb kaapuni papa conformal mea uhi no ka hana ʻana o ka hui pcb, hiki iā ʻoe ke kipa i DeepMaterial ma https://www.epoxyadhesiveglue.com/category/epoxy-conformal-coating/ no ka mea,ʻike'ē aʻe.
