Hoahoa Ritenga mai i te PCB Whakairo Taiaho
Hei wāhanga matua nui o ngā wāhanga hiko, he mea nui te PCB (papa hiko tā) mō te hoahoa me te hanga. Tērā pea kua mōhio koe ki ngā hangarau tā PCB tuku iho pērā i te tikanga whakawhiti toner, ā, kua whakaharatauhia e koe anō. Anei taku e hiahia ana ki te whakapuaki atu ki a koe ētahi atu tikanga whakairo PCB me te taputapu tapahi laser CO2, e āhei ai koe ki te whakarite ngāwari i ngā PCB kia rite ki ō hoahoa e pai ana ki a koe.
Te kaupapa me te tikanga o te whakairo PCB
- Whakaatuhia te papa hiko tānga poto
Ko te hoahoa PCB māmā rawa atu he mea hanga mai i te paparanga ārai me ngā paparanga parahi e rua (e kiia ana ko te parahi whakakikoruatia). Ko te FR-4 (karaehe whatu me te epoxy) te rauemi noa hei mahi ārai, i te wā e rite ana ki ngā tono mō ngā mahi motuhake, ngā hoahoa ara iahiko, me ngā rahi o te papa, ka taea hoki te whakamahi i ētahi dielectrics pēnei i te FR-2 (pepa miro phenolic), CEM-3 (karaehe kore-whatu me te epoxy). Ko te paparanga parahi te kawenga mō te tuku i te tohu hiko hei hanga hononga i waenga i ngā paparanga mā roto i ngā paparanga ārai me te awhina o ngā poka-roto, te tūhono-mata rānei. Nō reira, ko te kaupapa matua o te whakairo PCB he hanga i ngā tohu ara iahiko me te parahi me te whakakore i te parahi koretake, te wehe rānei i a rātou tetahi i tetahi.
Kia tirohia pototia te mātāpono o te whakairo PCB, ka tirohia ngā tikanga whakairo noa. E rua ngā tikanga whakahaere motuhake e hangai ana ki te mātāpono kotahi mō te whakairo i te parahi kua whakakikoruatia.
- Ngā otinga whakairo PCB
Ko tētahi o ngā whakaaro tika ko te tango i ngā wāhi parahi koretake e toe ana, engari ko ngā tohu porowhita. I te nuinga o te wā, ka whakamahia e mātou te otinga whakairo pērā i te ferry chloride hei whakatutuki i te tukanga whakairo. Nā te nui o ngā wāhi hei whakairo, he roa te wā me te manawanui nui.
Ko tētahi atu tikanga he tino mohio ake ki te whakairo i te rārangi tapahi (he tika ake te kī - te whakatakotoranga o te tahora ara iahiko), ka hua ake te ara iahiko tika me te wehe i te papa parahi kāore e tika ana. I roto i tēnei āhuatanga, he iti ake te parahi e whakairohia ana, ā, he iti ake te wā e pau ana. Kei raro nei ka arotahi ahau ki te tikanga tuarua hei whakamārama i te whakairo i tētahi PCB e ai ki te kōnae hoahoa.
Me pēhea te whakairo i tētahi PCB
Ngā mea hei whakarite:
papa hiko (papa parahi), peita rehu (pango matte), kōnae hoahoa PCB, tapahi laser, otinga konupora ferric (hei keri i te parahi), horoi waipiro (hei horoi), otinga horoi acetone (hei whakarewa i te peita), pepa kirikiri (hei whakakanapa i te papa parahi)
Ngā Hipanga Whakahaere:
1. Whakahaerehia te kōnae hoahoa PCB ki te kōnae vector (ka whakairohia te āhua o waho ki te laser) ka utaina ki roto i te pūnaha laser
2. Kaua e whakakorikoria te papa parahi ki te pepa kirikiri, engari horoia te parahi ki te waipiro mirimiri, ki te acetone rānei, kia kore ai he hinu, he ngako rānei e toe ana.
3. Puritia te papa hiko ki roto i te pliers ka pania he peita angiangi ki runga.
4. Whakatakotoria te papa parahi ki runga i te tēpu mahi, ka tīmata ki te whakairo i te mata ki te peita laser.
5. I muri i te whakairo, murua te toenga peita whakairo mā te whakamahi i te waipiro.
6. Tāpirihia ki roto i te otinga whakairo PCB (ferric chloride) hei whakairo i te parahi e kitea ana.
7. Whakakorea te peita rehu ki te wai horoi acetone (ki te tango peita rānei pērā i te Xylene, te wai whakahinuhinu peita rānei). Horoia, murua rānei te toenga o te peita pango i runga i ngā papa.
8. Keria ngā kōhao
9. Tūhonoa ngā huānga hiko mā roto i ngā kōhao
10. Kua oti
He aha i whiriwhiri ai i te PCB whakairo taiaho
He mea tika kia mōhiotia, ka whakairohia e te mīhini taiaho CO2 te peita rehu mata kia rite ki ngā tohu ara iahiko, kaua ki te parahi. He huarahi mohio tēnei ki te whakairo i te parahi kua kitea me ngā wāhi iti, ā, ka taea te mahi i te kāinga. Waihoki, ka taea e te kaitapahi taiaho iti-mana te mahi nā te ngāwari o te tango peita rehu. Nā te ngāwari o te wātea o ngā rauemi me te ngāwari o te whakahaere o te mīhini taiaho CO2 ka rongonui, ka māmā hoki te tikanga, nō reira ka taea e koe te hanga i te PCB i te kāinga, me te iti ake o te wā e pau ana. Hei tāpiri, ka taea te hanga tauira tere mā te PCB whakairo taiaho CO2, ka taea ai te whakarite me te tere o te whakatinana i ngā hoahoa PCB. Haunga te ngāwari o te hoahoa PCB, he mea nui te whiriwhiri i te kaitapahi taiaho CO2, arā, ko te tino tika me te hihi taiaho pai ka whakarite i te tika o te hononga ara iahiko.
(He whakamārama anō - he kaha te mīhini tapahi taiaho co2 ki te whakairo me te whakairo i runga i ngā rauemi kore-whakarewa. Mena kei te pōhēhē koe ki te mīhini tapahi taiaho me te mīhini whakairo taiaho, pāwhiritia te hononga hei ako atu:Te Rerekētanga: te kaiwhatu taiaho VS te kaiwhatu taiaho | (mimowork.com)
He pai te mīhini whakairo PCB CO2 laser mō te paparanga tohu, ngā paparanga takirua me ngā paparanga maha o ngā PCB. Ka taea e koe te whakamahi hei hanga i tō hoahoa PCB i te kāinga, ā, ka taea hoki te whakamahi i te mīhini laser CO2 ki te hanga PCB. Ko te auau teitei me te rite o te tino tika he painga pai mō te whakairo laser me te whakairo laser, e whakarite ana i te kounga teitei o ngā PCB. He mōhiohio taipitopito hei tiki mai imīhini whakairo laser 100.
Te whakairo PCB kotahi-haerenga mā te taiaho UV, te taiaho muka
Heoi anō, ki te hiahia koe ki te whakatutuki i te tukatuka tere-teitei me te iti ake o ngā tukanga mō te hanga PCB, ko te mīhini taiaho UV, taiaho matomato me te mīhini taiaho muka pea ngā kōwhiringa pai. Mā te whakairo tika i te parahi ki te taiaho hei waiho i ngā tohu ara iahiko ka tino whai hua i roto i te hanga ahumahi.
