To Tatou Tukanga
1. Te tukanga koura rumaki: Ko te kaupapa o te tukanga koura rumaki ko te whakatakoto i te paninga nickel-koura me te tae pumau, te kanapa pai, te paninga maeneene me te pai o te solderability i runga i te mata o te PCB, ka taea te wehea kia wha nga waahanga: pretreatment ( Te whakaheke hinu, te moroiti, te whakahoe, te ruku i muri), te nickel rumaki, te koura rumaki, te maimoatanga muri, (te horoi koura para, te horoinga DI, te whakamaroke).
2. Te tine rehu-mata: He iti ake te pāmahana eutectic kei roto i te mata o te koranu kore-mata.Ko te rahinga motuhake ka whakawhirinaki ki te hanganga o te koranu mata-kore.Hei tauira, ko te eutectic o SNAGCU he 217 nga nekehanga.Ko te pāmahana whakapiri ko te pāmahana eutectic me te 30-50 nga nekehanga, i runga i te hanganga.Ko te whakatikatika, ko te eutectic arahi he 183 nga nekehanga.He pai ake te kaha o te miihini, te kanapa, me etahi atu mata i te mata-kore.
3. Te rehu tine kore-arahi: Ka pai ake te mahi o te waea tine i roto i te mahi whakapiri.He ngawari ake te whakamahi i te waea tine mata, i te waea tine kore-mata, engari he paitini te mata, kaore e pai mo te tinana o te tangata mena ka whakamahia mo te wa roa.A ka nui ake te rewanga o te tine kore-matau i te tine mata, kia kaha ake ai nga hononga konuhono.
Ko te tukanga motuhake o PCB rua-taha papa iahiko tukanga production
1. Te keri CNC
Hei whakanui ake i te kiato o te huihuinga, kei te iti haere nga kohao i runga i te poari ara iahiko rua-taha o te PCB.Ko te tikanga, ka werohia nga papa pcb rua-taha me nga miihini keri CNC hei whakarite i te tika.
2. Te tukanga poka hiko
Ko te tukanga poka whakakikoruatia, e mohiotia ana ko te poka whakarewa, he tukanga e whakakikoruatia ana te pakitara katoa o te poka ki te whakarewa kia taea ai e nga tauira whakahaere i waenga i nga paparanga o roto me waho o te papa taiawhio taarua-rua te hono ki te hiko.
3. Tā mata
Ka whakamahia nga rauemi ta motuhake mo nga tauira taiawhio panui mata, tauira kanohi konohi, tauira tohu tohu, aha atu.
4. Whakakikoruatia te koranu tine-arahi
E rua nga mahi o nga koranu tine-arahi hiko: tuatahi, hei papa whakamarumaru anti-corrosion i te wa e whakakikoruatia ana me te tarai;tuarua, hei paninga solderable mo te papa oti.Ko nga koranu tine-arahi hiko me tino whakahaere i te pati me nga tikanga tukanga.Ko te matotoru o te paparanga whakakikorua tine-arahi kia neke ake i te 8 microns, me te taiepa poka kia kaua e iti iho i te 2.5 microns.
papa taiawhio taia
5. Te tarai
I te wa e whakamahi ana i te koranu tine-mata hei paparanga whakaatete ki te hanga i tetahi papa-taha-rua ma te tauira whakakikorua tikanga whakawai hiko, kaore e taea te whakamahi i te wairewa wairewa konukura konukura waikawa me te wairewa ferric chloride na te mea ka waikuratia te koranu tine.I roto i te mahi tarai, ko te "taraiwa taha" me te whakawhanui paninga he take e pa ana ki te tarai: te kounga
(1) Te waikura taha.Ko te waikura o te taha ko te totohu, te totohu ranei o nga taha o te kaikawe na te waikura.Ko te nui o te waikura o te taha e pa ana ki te otinga tarai, nga taputapu me nga tikanga tukanga.Ko te iti o te waikura taha ka pai ake.
(2) Kua whanui te paninga.Ko te whanui o te paninga na te matotoru o te paninga, ka nui ake te whanui o tetahi taha o te waea ki te whanui o te pereti o raro kua oti.
6. Whakakikorua koura
Ko te whakakikorua koura he pai te kawe hiko, he iti me te pumau o te whakapiri me te pai o te whakakakahu, a ko te mea pai rawa atu mo te whakakikorua mo nga mono papa iahiko.I te wa ano, he pai te pumau matū me te solderability, a ka taea hoki te whakamahi hei whakakikorua ki te waikura-aukati, whakakorikori me te whakamarumaru i runga i nga PCB Maunga.
7. Te rewa wera me te taumata o te hau wera
(1) Te rewa wera.Ko te pcb kua whakakikoruatia ki te koranu Sn-Pb ka whakawerahia ki runga ake i te rewa o te koranu Sn-Pb, kia hangai ai a Sn-Pb me Cu he puhui whakarewa, kia mato, kia kanapa, kia kore he titi, a ka kua pai ake te parenga waikura me te solderability o te paninga.sex.Te rewa-wera e whakamahia nuitia ana ko te glycerol wera-rewa me te infrared wera-rewa.
(2) Whakatauritenga hau wera.E mohiotia ana ano ko te rehu tine, ko te papa taiawhio kua whakakikoruatia ki te kanohi whakakikorua ka whakatauritea ki te rere o te hau wera, katahi ka uru ki te puna rewa whakarewa, katahi ka haere i waenganui i nga maripi hau e rua ki te pupuhi atu i te taikaha o te raima kia puta he kanapa, he kakahu, he maeneene. paninga solder.Ko te tikanga, ka whakahaerehia te pāmahana o te pati konuhono i te 230 ~ 235, ka whakahaeretia te pāmahana o te maripi hau i runga ake i te 176, ko te wa whakapiri ko te 5 ~ 8s, ka whakahaerehia te matotoru paninga i te 6 ~ 10 microns.
Papa Takirua Taapiri Taapiri
Mena ka whakakorehia te papa taiawhio rua-taha PCB, kaore e taea te hangarua, ka pa ana te kounga o te hangahanga ki te kounga me te utu o te hua whakamutunga.
