Hoʻolālā Maʻamau mai ka Laser Etching PCB
Ma ke ʻano he ʻāpana koʻikoʻi i nā ʻāpana uila, ʻo ka PCB (papa kaapuni paʻi) o ka hoʻolālā ʻana a me ka hana ʻana he mea nui ia i nā mea hana uila. Ua kamaʻāina paha ʻoe i nā ʻenehana paʻi pcb kuʻuna e like me ke ʻano hoʻoili toner a hoʻomaʻamaʻa paha iā ʻoe iho. Maanei makemake wau e kaʻana like me ʻoe i nā ʻano hana ʻoki pcb ʻē aʻe me kahi mea ʻoki laser CO2, e ʻae ana iā ʻoe e hoʻopilikino maʻalahi i nā pcbs e like me kāu mau hoʻolālā makemake.
Kumumanaʻo a me ke ʻano hana o ke kālai ʻana i ka pcb
- E hoʻolauna pōkole i ka papa kaapuni i paʻi ʻia
ʻO ka hoʻolālā pcb maʻalahi loa i kūkulu ʻia me ka papa insulating a me ʻelua mau papa keleawe (i kapa ʻia hoʻi he keleawe i uhi ʻia). ʻO ka maʻamau, ʻo FR-4 (aniani ulana a me ka epoxy) ka mea maʻamau e hana ma ke ʻano he insulation, i kēia manawa ma muli o nā koi like ʻole ma nā hana kikoʻī, nā hoʻolālā kaapuni, a me nā nui o ka papa, hiki ke hoʻohana ʻia kekahi mau dielectrics e like me FR-2 (pepa pulupulu phenolic), CEM-3 (aniani ulana ʻole a me ka epoxy). Lawe ka papa keleawe i ke kuleana no ka hāʻawi ʻana i ka hōʻailona uila e kūkulu i kahi pilina ma waena o nā papa ma o nā papa insulation me ke kōkua o nā lua ma o ka lua a i ʻole ka solder ma luna. No laila, ʻo ke kumu nui o ka etching pcb ʻo ia ka hana ʻana i nā kaha kaapuni me ke keleawe a me ka hoʻopau ʻana i ke keleawe pono ʻole a i ʻole e hoʻokaʻawale iā lākou mai kekahi i kekahi.
Ke nānā pōkole nei mākou i ke kumumanaʻo o ke kālai ʻana i ka pcb, e nānā mākou i nā ʻano kālai maʻamau. ʻElua mau ʻano hana like ʻole e pili ana i ke kumumanaʻo like e kālai ai i ke keleawe i uhi ʻia.
- nā hoʻonā etching PCB
ʻO kekahi no ka noʻonoʻo pololei ʻo ia ka wehe ʻana i ke koena o nā wahi keleawe pono ʻole koe wale nō nā kaha kaapuni. ʻO ka maʻamau, hoʻohana mākou i ka hopena etching e like me ka ferry chloride e hoʻokō ai i ke kaʻina hana etching. Ma muli o nā wahi nui e eli ʻia, pono e lawe ʻia kahi manawa lōʻihi a me ke ahonui nui.
ʻOi aku ka akamai o ke ʻano hana ʻē aʻe e kahakaha i ka laina ʻokiʻoki (ʻoi aku ka pololei - ke kaha kiʻi o ka hoʻolālā kaapuni), e alakaʻi ana i ka alakaʻi kaapuni pololei ʻoiai e hoʻokaʻawale ana i ka panela keleawe pili ʻole. Ma kēia kūlana, emi ka keleawe i kahakaha ʻia a emi ka manawa i hoʻopau ʻia. Ma lalo nei e kālele ana au i ke ʻano hana ʻelua e kikoʻī i ke ʻano o ke kahakaha ʻana i kahi pcb e like me ka faila hoʻolālā.
Pehea e kahakaha ai i kahi PCB
He aha nā mea e hoʻomākaukau ai:
papa kaapuni (papa keleawe), pena pīpī (ʻeleʻele matte), faila hoʻolālā pcb, mea ʻoki laser, hopena ferric chloride (e ʻoki i ke keleawe), holoi waiʻona (e hoʻomaʻemaʻe), hopena holoi acetone (e hoʻoheheʻe i ka pena), pepa one (e hoʻopili i ka papa keleawe)
Nā ʻanuʻu hana:
1. E lawelawe i ka faila hoʻolālā PCB i ka faila vector (e ʻoki ʻia ke koʻokoʻo waho e ka laser) a hoʻouka iā ia i loko o kahi ʻōnaehana laser
2. Mai hoʻowali i ka papa keleawe me ka pepa one, a e hoʻomaʻemaʻe i ke keleawe me ka waiʻona hamo a i ʻole ka acetone, e hōʻoia ana ʻaʻohe aila a me ka momona i koe.
3. E paʻa i ka papa kaapuni i loko o nā pliers a hāʻawi i kahi pena pīpī lahilahi ma luna o kēlā
4. E kau i ka papa keleawe ma ka papa hana a hoʻomaka i ke kahakaha ʻana i ka pena ʻili me ka laser
5. Ma hope o ke kālai ʻana, e holoi i ke koena pena i kālai ʻia me ka waiʻona
6. E hoʻokomo i loko o ka hopena etchant PCB (ferric chloride) e etch i ke keleawe i hōʻike ʻia
7. E hoʻonā i ka pena pīpī me ka mea hoʻoheheʻe acetone (a i ʻole kahi mea wehe pena e like me Xylene a i ʻole ka mea hoʻokahe pena). E ʻauʻau a holoi paha i ke koena o ka pena ʻeleʻele mai nā papa i loaʻa.
8. E wili i nā lua
9. E hoʻopili i nā mea uila ma o nā lua
10. Pau
No ke aha e koho ai i ka PCB etching laser
He mea kūpono ke hoʻomaopopo ʻia, ʻo ka mīkini laser CO2 e kālai ana i ka pena pīpī ʻili e like me nā kaha kaapuni ma kahi o ke keleawe. He ala akamai ia e kālai ai i ke keleawe i hōʻike ʻia me nā wahi liʻiliʻi a hiki ke hoʻokō ʻia ma ka home. Eia kekahi, hiki i ka mea ʻoki laser haʻahaʻa ke hana mahalo i ka maʻalahi o ka wehe ʻana i ka pena pīpī. ʻO ka maʻalahi o ka loaʻa ʻana o nā mea a me ka hana maʻalahi o ka mīkini laser CO2 e hoʻolilo i ke ʻano i mea kaulana a maʻalahi, no laila hiki iā ʻoe ke hana i ka pcb ma ka home, e hoʻolilo ana i ka manawa liʻiliʻi. Eia kekahi, hiki ke hoʻokō ʻia ka prototyping wikiwiki e ka PCB engraving laser CO2, e ʻae ana i nā hoʻolālā pcbs like ʻole e hoʻopilikino ʻia a hoʻokō wikiwiki ʻia. Ma waho aʻe o ka maʻalahi o ka hoʻolālā pcb, aia kekahi kumu nui e pili ana i ke kumu e koho ai i ka mea ʻoki laser co2 ʻo ka pololei kiʻekiʻe me ke kukuna laser maikaʻi e hōʻoiaʻiʻo i ka pololei o ka pilina kaapuni.
(Wehewehe hou aʻe - loaʻa i ka mea ʻoki laser co2 ka hiki ke kahakaha a me ke kālai ʻana ma nā mea ʻaʻole metala. Inā huikau ʻoe me ka mea ʻoki laser a me ka mea kahakaha laser, e kaomi i ka loulou e aʻo hou aku:Ka ʻokoʻa: mea kālai laser VS mea ʻoki laser | (mimowork.com)
He kūpono ka mīkini ʻokiʻoki pcb laser CO2 no ka papa hōʻailona, nā papa pālua a me nā papa he nui o nā pcbs. Hiki iā ʻoe ke hoʻohana iā ia e hana i kāu hoʻolālā pcb ma ka home, a hoʻokomo pū i ka mīkini laser CO2 i ka hana pcbs kūpono. ʻO ka hana hou ʻana kiʻekiʻe a me ke kūlike o ka pololei kiʻekiʻe he mau pono maikaʻi loa no ka ʻokiʻoki laser a me ke kahakaha laser, e hōʻoiaʻiʻo ana i ka maikaʻi kiʻekiʻe o nā PCB. ʻIke kikoʻī e loaʻa maimea kālai laser 100.
ʻO ke kālai ʻana i ka PCB hoʻokahi-pass e ka laser UV, laser fiber
Eia kekahi, inā makemake ʻoe e hoʻokō i ka hana wikiwiki a me nā kaʻina hana liʻiliʻi no ka hana ʻana i nā pcbs, ʻo ka laser UV, ka laser ʻōmaʻomaʻo a me ka mīkini laser fiber paha nā koho kūpono. ʻO ke kālai pololei ʻana i ke keleawe e waiho i nā kaha kaapuni e hāʻawi i ka maʻalahi nui i ka hana ʻoihana.
✦ E hoʻomau ka hoʻonui ʻana o nā ʻatikala, hiki iā ʻoe ke loaʻa hou aʻe e pili ana i ka ʻoki ʻana i ka laser UV a me ke kālai ʻana i ka laser ma nā pcbs i ka wā e hiki mai ana.
E leka uila pololei mai iā mākou inā ʻoe e ʻimi nei i kahi hopena laser no ka etching pcb
ʻO wai mākou:
He hui i hoʻolālā ʻia e ka hopena ʻo Mimowork e lawe mai ana i ka ʻike hana hohonu he 20 mau makahiki e hāʻawi i nā hoʻonā hana laser a me ka hana ʻana i nā SME (nā ʻoihana liʻiliʻi a me waena) ma loko a puni nā lole, nā kaʻa, a me nā wahi hoʻolaha.
ʻO kā mākou ʻike waiwai o nā hoʻonā laser i hoʻokumu hohonu ʻia i ka hoʻolaha, kaʻa a me ka mokulele, ke ʻano a me ke kapa, ka paʻi kikohoʻe, a me ka ʻoihana lole kānana e hiki ai iā mākou ke hoʻolalelale i kāu ʻoihana mai ka hoʻolālā a hiki i ka hoʻokō ʻana i kēlā me kēia lā.
