Ua hoʻohana ʻia ke ʻano hana kaha ʻana ʻo V i mau makahiki i ka hana ʻana o papa kaapuni i paʻi ʻia (PCB). Me ka ʻenehana hoʻohua PCB e holomua wikiwiki nei, he mea nui e makaʻala i nā ʻōkuhi helu PCB hou loa e ukali ai a pehea e ʻokoʻa ai i nā mea āu i hoʻohana ai ma mua.

Hoʻopili ke kaʻina helu i ʻelua mau lau e kaʻapuni kokoke i kahi kiko-i-kiko ke neʻe ka PCB ma waena o nā pahi. ʻAneʻane like ke kaʻina me ka ʻoki ʻana i kahi pizza i loko o ka pancake, ʻoki ʻana i ka pizza i nā ʻāpana lahilahi a laila neʻe wikiwiki i ka huahana i kahi hana aʻe, hiki ke hoʻomaikaʻi i ka hana holoʻokoʻa. No laila inā ʻoe e hoʻohana i ka heluʻai ʻana ma kāu PCB? He aha nā drawbacks kūpono o kēia kaʻina hana?

Papa kaapuni i paʻi ʻia

Inā he square a huinahā paha kāu PCB, he mau laina pololei nā ʻaoʻao āpau a hiki keʻoki ʻia ma ka mīkini V-notch. ʻO ka nīnau e nīnau ai, he kūpono ia no ka māka ʻana, a he mau wahi ʻē aʻe paha e pono e kamaʻilio ʻia? I ka helu a i ʻole e helu? Eia kekahi mau kumu no ka hōʻole ʻana e pane.

ʻO Score ka lahilahi PCBS

Paʻapū ʻo nā papa kaapuni paʻi ʻoi aku ka paʻakikī ma mua o 0.040 iniha no nā kumu he nui. Koi ʻia ka palena iki o 0.012 “e hoʻopaʻa i ka wili ʻano V, ʻoiai ua waiho ʻia ka pahi notch hema (coil) i ka manawa hoʻokahi 0.010” – kahi hohonu o 0.012 “ma nā ʻaoʻao ʻelua e hana i ka 0.020″ +/- 0.004 ” upena liʻiliʻi ma mua o 0.040 “.

ʻO Thinner i paʻi papa kaapuni i kekahi deflection wale nō i ka mea. ʻO ka PCBS maʻalahi e hoʻohana ana i ka hana haki notched e waiho paha i nā kihi ʻino a kau i nā olonā. ʻO ka kaohi ʻana i ke kaʻina hana me nā mea lahilahi a ʻae ʻoi aku ka paʻakikī o nā kahamaha nui. Kūleʻa ka pahi i ke kau ahonui o ka hohonu o ka notch mai luna a lalo, a aia kahi kikoʻī ʻoi loa o ka pololei e hōʻoia i ka haki ʻole o ka mea ākea i ka hui ʻana. Ke kaulike ʻole ka hohonu o ka notch ma waena o ka hema a me ka ʻākau, ʻoi aku ka paʻakikī o ka ʻāpana e haki, e waiho ana i nā olonā a me nā ʻaoʻao haʻihaʻi hiki.

Loaʻa ʻia ka PCB i ka lālani

Hoʻonui ʻia ka scribing, ʻoi aku ka nāwaliwali o nā panela hoʻonohonoho, e hopena ai i ka lawelawe palupalu ʻana, nā huina hoʻopōʻino a me / a i ʻole nā ​​pilikia hui.

Nā ʻāpana me nā helu liʻiliʻi liʻiliʻi

ʻO ka liʻiliʻi o ka ʻīniha kuea o ka papa, ʻo ka ʻoi aku ka paʻakikī o ka hemo ʻana. Ke liʻiliʻi ka nui o ka PCB, ʻoi aku ka paʻakikī o nā papa mānoanoa ma mua o 0.062. Ma lalo o 1 ʻīniha i kēlā me kēia ʻaoʻao e koi paha i nā pono hana hou e hoʻokaʻawale i nā ʻāpana.

Helu i ka PCB ʻoi aku ka lōʻihi

Palupalu paha nā papa kaapuni me ka lōʻihi o X a Y paha (12 ʻīniha a ʻoi paha) inā ʻōpala ʻia lākou. Hiki ke hoʻohui i nā mea kaumaha i kahi pūʻali nāwaliwali i mea e haki ai nā panela i ka wā o ka lawelawe ʻana, hoʻākoakoa ʻana, a i ʻole ka halihali. Ke koho nei i nā helu lele a i ʻole ke kaʻina hoʻokele kapu he koho ʻoi aku paha.

Pā hoʻohelu

Inā ʻoe e māka ana i ka PCBS ʻoi aku ma mua o 0.096 ʻīniha ka mānoanoa, e hoʻohana i ka hoʻolālā like, me nā pahi ʻelua e ʻoki hohonu ana i ka papa laminate, e waiho ana i ka upena 0.020 ʻīniha +/- 0.004 iniha. Ma luna o kēia mānoanoa, paʻakikī e haki, no ka mea ʻaʻole lawa ke kūlou. Hiki i nā pahi mānoanoa ke hoʻohana i kēia hana no nā papa mānoanoa, akā hiki i kekahi manawa ke alakaʻi i nā pilikia me ke keleawe a hiki i ke kaʻe āpau.

Ka mea hana helu

Loaʻa nā pono hana e kōkua i ka decanting PCBS. Eia nō naʻe, pono e hoʻohana pololei a nānā ʻia no ka pololei e pale ai i ka hōʻino ʻana o ka lihi, ka haki a i ʻole ka ʻili ʻana i ka ʻili. ʻO ka lawelawe ʻana keu o ka PCBS i ʻākoakoa piha mau i ka makaʻu.

Hoʻohui i kahi huina a i ʻole radius i ka ʻāpana

Keakea nei kēia i ka hiki ke hoʻohana i ke kaʻina helu?

ʻAʻole, akā pono ʻoe i nā kihi pālahalaha e wili i ka papa. ʻO ka maʻamau, i ka hoʻohana ʻana i ke ʻano notch, e pae ka PCBS me kekahi. ʻOki ka mea ʻokiʻoki i ka luna a me ka lalo.

E hana me nā kihi a i ʻole radii, pono ʻoe e haʻalele i kahi ma waena o ka PCBS. Hoʻohana kahi mea hoʻolālā Router maʻamau i ka 0.096 “mīkini wili palaoa e koi ana ma ka liʻiliʻi o 0.100” e hoʻomaʻemaʻe maʻemaʻe ma waena o nā ʻāpana. Aia kekahi ʻōpala liʻiliʻi ma waena o nā ʻāpana. ʻAʻole ia e koi ʻia e hoʻohana i ka 0.100 “spacing a notch cara ma waena o nā papa, ʻoiai me nā pono hana, paʻakikī loa e haki. Ke koi ʻia kahi hakahaka, paipai ʻia e hoʻohana i ka 0.200 “a i ʻoi aku ka nui o ka spacing no nā nicks.

Nā lula hoʻolālā PCB no nā mea hoʻolālā

Pane i kahi nīnau maʻamau; ʻAe, hiki iā ʻoe ke koho kokoke i nā papa kaapuni i paʻi ʻia me ke kaʻe pololei, akā pono paha ʻoe e hoʻohana i kahi hui o ka helu ʻana a me nā uea.

ʻO ka mahana lamineka wela me ka kiʻekiʻe ma mua o 150TG he mea nui a me ka microstructure. Mai hoʻohana i nā palena ʻāpana maʻamau i hoʻohana ʻia i ka standard material 130tg. Pono nā hakina hohonu e haki maʻalahi i kēia mea ulana ikaika. No nā mea wela kiʻekiʻe, e hoʻohana i ka hei ʻo 0.015 “+/- 0.004”.

Mai ka hao kihi, pono e hoʻopili ʻia ka papa pale i ka mānoanoa o ka papa kaapuni i paʻi ʻia. Ke kūlike a i ʻole ma lalo o 0.062 “, ka mamao ma waena o ka mea hao a me ka lihi maoli o ka pā ma 0.015“. ʻO kēia kahi helu kūmole maikaʻi. Hiki ke hoʻohana ʻia nā papa mānoanoa 0.096 “a i ʻole 0.125” i luna a me 0.020 “a i ʻole ke kiʻekiʻe inā ʻae ka manawa i nā hana āpau mai ka lihi o ke kāleka.

No nā papa kaapuni i paʻi ʻia ma lalo o 0.040 “i ka mānoanoa, e hoʻolālā mau e hoʻohana wale i nā lugs no ka uea ʻana e hōʻalo i nā pilikia.
