ʻO ka inika PCB e pili ana i ka inika i hoʻohana ʻia ma PCB. Ano, e kaʻana like me oe i na ano a me na ano o ka PCB inika?

1 、 Nā hiʻohiʻona o ka inika PCB

1-1. Viscosity a me thixotropy
I ke kaʻina hana o nā papa kaapuni paʻi, ʻo ka paʻi pale kekahi o nā hana koʻikoʻi a koʻikoʻi. I mea e loaʻa ai ka ʻoiaʻiʻo o ka hana hou ʻana o ke kiʻi, pono e loaʻa i ka inika ka viscosity maikaʻi a me ka thixotropy kūpono.
1-2. ʻO ka maikaʻi
ʻO nā puaʻa a me nā mea hoʻopiha mineral o nā inika PCB paʻa mau. Ma hope o ka wili maikaʻi ʻana, ʻaʻole i ʻoi aku ka nui o kā lākou ʻāpana ma mua o 4/5 microns, a hana i kahi moku holo homogenized ma ke ʻano paʻa.

2. Nā ʻano o nā ʻīnika PCB

Hoʻokaʻawale ʻia nā ʻīnika PCB i ʻekolu mau ʻāpana: kaapuni, solder mask a me nā inika silkscreen.

2-1. Hoʻohana ʻia ka ʻīnika kaapuni ma ke ʻano he pale e pale ai i ka ʻino o ke kaapuni. Mālama ia i ka laina i ka wā etching. He mea maʻamau ka wai photosensitive; ʻElua ʻano ʻano: acid corrosion resistance a alkali corrosion resistance.
2- 2. Ua pena ʻia ka ʻīnika kūʻai kūʻai ma ke kaapuni ma hope o ka pau ʻana o ke kaapuni ma ke ʻano he laina pale. Aia nā ʻano wai photosensitive, mālama wela a me nā ʻano paʻakikī UV. Hoʻopaʻa ʻia ka pad paʻa ma ka papa e hoʻomaʻamaʻa i ka hoʻopili ʻana i nā ʻāpana a pāʻani i ka hana o ka insulation a me ka pale ʻana i ka oxidation.
2-3. Hoʻohana ʻia ka ʻīnika Silkscreen e hōʻailona i ka ʻili o ka papa, e like me ka hōʻailona o nā ʻāpana, he keʻokeʻo maʻamau.

Eia kekahi, aia nā ʻīnika ʻē aʻe, e like me ka inika adhesive strippable, ka inika paʻi kālā, etc.
