He aha ka Silicone Conformal Coating No PCB

Hiki ke poino ke kaapuni uila e ka corrosion inā he papa wai condensing mau. ʻO kekahi mau ion i hoʻoheheʻe wale ʻia no ka hoʻomaka ʻana o nā hopena electrochemical, e hoʻoheheʻe i nā metala ma ka papa a i ʻole ka hana ʻana i nā leka uila ma waena o nā mea hoʻokele. No ka hoʻonui i ke ola o ka uila, he mea nui nā pale pale. ʻO nā mea hoʻopili silicone conformal ʻo ia kekahi o nā mea maikaʻi loa i ka hāʻawi ʻana i ka palekana i makemake nui ʻia.

Pili ʻo Silicone i nā noi ʻoihana a me nā kūlana ma muli o kona hilinaʻi a me nā pono. Inā ʻoe e ʻimi nei i ka pale o ka papa kaapuni paʻi maikaʻi loa, ʻo ka silicone conformal coating ka mea āu e noʻonoʻo ai.

ʻO nā waiwai 

He mea koʻikoʻi ka hoʻopili maikaʻi ʻana a me ka loaʻa ʻana o ka wai i ka wā e ʻimi ai i ka pale no ka circuitry lalo a me nā ʻili metala. Hāʻawi ka silicone cured i ka pale e pono ai ma nā modula a me nā mea uila e like me ka hoʻopau ʻana i ka wai. ʻOiai ʻo ka mahu wai i loko o nā noi haʻahaʻa hiki ke komo i kāu interface, ʻaʻohe hopena maikaʻi e ʻike ʻia ke kau ʻia ka uhi silicone. ʻO ka hoʻopili silicone maikaʻi e hoʻopau i nā āpau e hiki ai i ka wai ke condense. ʻO nā waiwai e hoʻolilo i nā pale silicone i koho kaulana ʻo ia:

• Hoʻoikaika kūʻai
• Paʻi hoʻomāinoino
• Māmā a haʻahaʻa ka ʻona
• Hana maikaʻi loa i ka wela wela
• Kōleʻa maʻalahi
• Paʻa kemika maikaʻi, me ka ozone a me ka UV degrading
• Hiki ke lawe māmā

Nā pōmaikaʻi 

ʻO nā uhi kuʻuna ʻO nā mea i hoʻokumu ʻia i ka silicone ke ʻano abrasion-resistant, palupalu, a paʻakikī paha, e pili ana i kā lākou hana ʻana. E ʻike ʻoe i nā ʻili i loko o nā ʻano hoʻoheheʻe paʻa, me nā mea paʻa e koi ana i ka wela, UV, a i ʻole ka makū e hoʻōla. ʻO ka wehe ʻana i nā uhi e pono ai nā mea hoʻopale kemika, akā he aha nā mea maikaʻi o nā uhi conformal i hana ʻia mai ke silicone?

Paʻa laula wela ākea. Ua ʻike nui ʻia a koho ʻia ʻo Silicone ma muli o kāna mau pono. ʻO ka ʻoiaʻiʻo hiki iā ia ke pale i nā wela kiʻekiʻe ʻoiai i ka wā kaʻa uila e hilinaʻi nui ʻia. ʻO ka laulā mai -40 degere a ma kahi o 200 degere Celsius, he mea kupanaha loa ia e hoʻohālikelike ʻia i nā ʻano uhi ʻē aʻe.

ʻoluʻolu. ʻO ka maʻalahi o ka uhi silicone e kūpono ia no ka hāʻawi ʻana i ka hopena a me ka pale dampening. He maʻalahi a maʻalahi ka mea e pono ai ma nā noi like ʻole.

ikehu ili haahaa. He mea nui ka ikehu ili haahaa no ka pulu maikai ana. ʻO kēia kahi pōmaikaʻi āu e kū ai e leʻaleʻa i ka wā e koho ai ʻoe i nā uhi conformal silicone.

Kūʻē kūʻokoʻa i ka wai. Ke hana pono ʻia, ʻaʻole pono ʻoe e hopohopo e pili ana i ka pōʻino o ka makū no ka mea hāʻawi ka uhi i ka corrosion hilinaʻi a me ka pale ʻana i ka wai.

Ka ikaika dielectric kiʻekiʻe. ʻO kēia ke ʻano o ka mea e kū ai i nā māla uila kiʻekiʻe me ka hiki ʻole o ka conduction. ʻO ia, ma ka hoʻihoʻi, pale i nā hāmeʻa mai nā pōkole uila, ka hoʻokuʻu static, a me ka arcing voltage kiʻekiʻe.

ʻO ke noi 

I nā conformal coatings, hoʻohana ʻia nā ʻano hana like ʻole. No nā uhi silicone, ʻo ka mea maʻamau i hoʻohana ʻia:

Hiki ke hoʻopaʻa ʻia i ka lima a i ʻole ka automate. Hoʻohana kēia ʻano i nā lima robotic e hoʻopaʻa i nā mea hana, hoʻohaʻahaʻa a hoʻopaʻa iā lākou i loko o kahi pahu i hoʻopiha ʻia me ka uhi silicone. Hāʻawi kēlā me kēia dip i ka mānoanoa like, a ʻoi aku ka maikaʻi o ka ʻenehana no nā hana kiʻekiʻe.

ʻO ka pīpī ʻana ke ʻano noi ʻē aʻe āu e hoʻohana ai me nā uhi silicone. Hiki iā ʻoe ke hoʻohana i kahi pū puhi a i ʻole aerosol e hoʻohana ai, a he ala kūpono ia no nā puke nui no ka mea he wikiwiki a maʻalahi hoʻi e hana hou.

Hiki iā ʻoe ke hoʻohana i ka palaki ʻana e hoʻopili i nā uhi silicone. Hoʻopili ka mea hoʻohana i ka uhi a hiki iā ia ke kahe ma luna o ka papa. Kūpono kēia ʻano hana i ka hana hou ʻana, a me ka holo haʻahaʻa.

No ka mea hou aku He aha ka silicone conformal coating no ka pcb, hiki iā ʻoe ke kipa i DeepMaterial ma https://www.epoxyadhesiveglue.com/what-is-silicone-conformal-coating-for-electronics-pcb-circuit-board-protection/ no ka mea,ʻike'ē aʻe.
