Ke hāʻule nei ke kaula keleawe o PCB (ʻike ʻia ʻo ka hoʻolei keleawe) ʻaʻole maikaʻi. ‘Lelo nā hale hana PCB ʻo ka laminate ka pilikia a koi i kā lākou mau hale hana e hali i nā pohō maikaʻi ʻole. Wahi a kaʻu mau makahiki o ka hoʻopiʻi hoʻopiʻi hoʻopiʻi ʻana a ka mea kūʻai aku, ʻo nā kumu maʻamau no ka hoʻolei ʻana o ke keleawe hale hana PCB penei.

I. PCB hale hana hana hana:

1. ʻoi aku ka nui o ka hoʻopaʻa ʻana o ke keleawe keleawe, hoʻohana ʻia ka foil keleawe electrolytic i hoʻohana ʻia i ka mākeke i hoʻokahi galvanized hoʻokahi ʻaoʻao (ʻike ʻia ʻo ashing foil) a me nā pale keleawe hoʻokahi ʻaoʻao (ʻike ʻia he ʻulaʻula), ʻoi aku ka nui o ka hoʻolei keleawe ma mua o 70um galvanized keleawe pepa hao, ʻulaʻula pepa a me 18um ma lalo iho o ka ashing foil maʻamau ʻaʻohe o ka hoʻolei keleawe. Ke ʻoi aku ka maikaʻi o ka hoʻolālā laina mea kūʻai aku ma mua o ka laina etching, inā hoʻololi ʻia nā kikoʻī keleawe a hoʻololi ʻole ʻia nā palena etching, noho mau ke keleawe keleawe i ka hopena paʻa paʻa loa. Ma muli o ke kinikini he metala hana ia, ke komo ka uea keleawe ma PCB i ka hopena etching no ka manawa lōʻihi, e alakaʻi ʻia ia i ka luku ʻia ʻana o ka laina, a laila hopena ʻia a hoʻokaʻawale ʻia kahi papa zinc laina maikaʻi. , ʻo ia hoʻi, hāʻule ke kaula keleawe. ʻO kekahi kūlana ʻaʻohe pilikia me nā palena ETCHING o PCB, akā holoi ʻia ke etching ma hope o ke kāwili ʻana a maikaʻi ʻole ka hoʻomaloʻo ʻana, a laila hoʻopuni ʻia ka uea keleawe e ka wai ʻino e waiho ana ma ka SURFACE o PCB. Inā ʻaʻole e mālama ʻia no ka manawa lōʻihi, e hoʻonui ʻia ka uea keleawe a hoʻolei ʻia ke keleawe. ʻO ka hana maʻamau o kēia ʻano hanana e hoʻopili ʻia i nā laina maikaʻi, a i ʻole ka wā pulu o ke anilā, e ʻike like ka PCB āpau i kahi ʻino like ʻole, e hemo i ka uea keleawe e ʻike ai i kona a me nā ʻano mauʻu (ʻo ka mea i kapa ʻia ka papa coarsening) ua loli, ʻokoʻa. ka waihoʻoluʻu keleawe pepa keleawe maʻamau, e ʻike ai i ke kala keleawe kumu kumu, nā laina mānoanoa o ka ikaika o ka peel keleawe i maʻamau.

2. I ke kaʻina hana o PCB, kū ka pilina kūloko, a hoʻokaʻawale ʻia ka uea keleawe mai nā kumuwaiwai e ka ikaika mīkini kūwaho. Hoʻonohonoho maikaʻi ʻole ʻia kēia hana maikaʻi ʻole a kuhikuhi ʻole paha, e ʻike maopopo ʻia ka ʻokoʻa o ka uea keleawe leʻaleʻa, a i ʻole ma ke ala like o ka maka. Ke ʻili ʻana i ka uea keleawe ma kahi maikaʻi ʻole e ʻike ai i ka lauoho lauoho keleawe, hiki iā ʻoe ke ʻike he maʻamau ke kala o ka lauoho lauoho keleawe, ʻaʻohe ʻaʻai ʻino maikaʻi ʻole, a ʻo ka ikaika o ka peel keleawe peel ka mea maʻamau.

3. ʻAʻole kūpono ka hoʻolālā kaapuni PCB, me ka hoʻolālā ʻōmaʻomaʻo keleawe lahilahi, ʻo ia hoʻi ka mea e hoʻopiʻi nui ai i ke kaapuni ʻana a me ka hoʻolei keleawe.

ʻElua, nā kumu hana laminate:

Ma lalo o nā kūlana maʻamau, ʻoiai ke kaomi ʻia o ka laminate ma kahi mahana wela no 30 mau minuke, hoʻohui paʻa ʻia ka pepa keleawe a me ka pepa semi-cured, no laila ʻaʻole pili ka kaomi ʻana i ka ikaika paʻa o ka pepa keleawe a me ka substrate i loko o ka lamineka. Eia nō naʻe, i ke kaʻina o ka laminate stacking a stacking, inā PP haumia a pōʻino o ke keleawe foil lauoho ʻili e alakaʻi pū ʻia hoʻi i ka lawa ʻole o ka paʻa ma waena o ka pepa keleawe a me nā mea ma hope o ka lamination, e hopena ana i ka hoʻonohonoho ʻana (no nā papa nui wale nō) a i ʻole ka uea keleawe sporadic. ke hāʻule nei, akā ʻaʻole e loaʻa kahi kaha ʻili keleawe keleawe e kokoke ana i ka laina ana i ana ʻia.

ʻEkolu, laminate maka mea:

1. ʻo ka mea i ʻōlelo ʻia ma luna electrolytic keleawe pepa hao MAO pepa hao a i ʻole ke keleawe e hoʻopili ana i nā huahana i hana ʻia, ke MAO foil i kahi kiʻekiʻe o ka hana ʻana, a i ʻole ka zinc / plating keleawe, ka uhi ʻana i ka dendrite, ʻaʻole lawa ka ikaika o ka peel o ka pepa keleawe ponoʻī, kumu ʻia. e ka pepa maikaʻi ʻole ma hope o ke kaomi ʻana i ka pepa i hana ʻia ai ka hale hana uila uila PCB, hāʻule ka uea keleawe e nā haʻalulu kūwaho. ʻO kēia ʻano keleawe ʻinoʻino e hemo ana i ka uea keleawe e ʻike ai i ka pale o ka lauoho keleawe (ʻo ia hoʻi, ka ʻili pili me nā mea kumu) ʻaʻole ia e ʻike ʻia i ka lū ʻana o ka ʻaoʻao, akā e ʻilihuna loa ka ʻāpana holoʻokoʻa o ka ʻili keleawe.

2. ʻilihune ka maʻalahi o ka pepa keleawe a me ke kēpau: kekahi laminate hana kūikawā i hoʻohana ʻia i kēia manawa, e like me ka pepa HTg, no ka mea ʻaʻole like ka ʻōnaehana kēpau, ʻo ka resin PN he resin, he maʻalahi ka hale kaula mole mole, ka crosslinking haʻahaʻa ke kēkelē ke hoʻōla, hoʻopaʻa ʻia e hoʻohana i ka pepa keleawe keleawe kūikawā kūikawā a me ke kūlike. Ke hana ʻole ka laminate e hoʻohana ana i ka pepa keleawe keleawe a ʻaʻole kūlike ka ʻōnaehana resin, a laila ʻaʻole lawa ka hopena o ka pā e uhi ana i ka hao hao, e ʻike ʻia hoʻi ka plug-in i ka ʻili kila.
