一.Te mahi ringihanga parahi

1. Pretreatment wahi: I mua i te ringihanga parahi ōkawa, Me pretreated te poari PCB, tae atu ki te horoi, tango waikura, horoi me te tahi atu kaupae ki te whakarite i te ma me te maeneene o te mata o te poari, me te whakatakoto i te turanga pai mo te ringihanga parahi ōkawa.

2. Ko te whakakikorua parahi korehiko: Ko te whakakikorua i te paparanga o te wai whakakikorua parahi electroless i runga i te mata o te papa taiawhio ki te whakakotahi matū ki te pepa parahi hei hanga i te kiriata parahi ko tetahi o nga tikanga tino noa o te whakakikorua parahi.Ko te painga ko te matotoru me te rite o te kiriata parahi ka taea te whakahaere pai.

3. Te whakakikorua parahi miihini: Ko te mata o te papa porowhita kua hipokina ki te paparanga parahi ma te tukatuka miihini.Koinei hoki tetahi o nga tikanga whakakikorua parahi, engari he nui ake te utu o te whakaputa i te whakakikorua parahi matū, na ka taea e koe te whiriwhiri ki te whakamahi i a koe ano.

4. Te paninga parahi me te lamination: Ko te taahiraa whakamutunga o te tukanga whakakikorua parahi katoa.I muri i te whakakikorua parahi, me pehi te pepa parahi ki runga i te mata o te papa taiawhio ki te whakarite kia oti te whakauru, na reira ka whakarite i te kawe me te pono o te hua.

二.Te mahi o te paninga parahi

1. Whakaititia te impedance o te waea whenua me te whakapai ake i te kaha anti-porearea;

2. Whakaitihia te heke ngaohiko me te whakapai ake i te kaha o te kaha;

3. Honoa ki te waea whenua hei whakaiti i te waahi kapiti;

三.Nga whakatupato mo te ringihanga parahi

1. Kaua e ringihia te parahi ki te waahi tuwhera o te waea waea i te paparanga waenga o te papa maha.

2. Mo nga hononga ira-kotahi ki nga papa rereke, ko te tikanga ko te hono ma te 0 ohm parenga, pirepire aukume, inductors ranei.

3. I te wa i timata ai te hoahoa waea, me pai te rere o te waea whenua.Kaore e taea e koe te whakawhirinaki ki te taapiri i nga vias i muri i te ringihanga parahi hei whakakore i nga titi whenua kore hono.

4. Ringihia te parahi ki te taha o te oscillator tioata.Ko te oscillator tioata i roto i te ara iahiko he puna tukunga auau teitei.Ko te tikanga ko te ringihia te parahi ki te taha o te oscillator tioata, katahi ka werohia te anga o te oscillator tioata motuhake.

5. Me whakarite te matotoru me te riterite o te paparanga kakahu parahi.Ko te tikanga, kei waenganui i te 1-2oz te matotoru o te paparanga kakahu parahi.Ko te paparanga parahi he tino matotoru, he kikokore rawa ranei ka pa ki te mahi kawe me te kounga tuku tohu o te PCB.Ki te he pāhiwihiwi te paparanga parahi, ka meinga te reira pokanoa me te ngaro o nga tohu ara iahiko i runga i te poari ara iahiko, e pa ana ki te mahi me te pono o te PCB.
