Hanaankayaga
1. Geedi socodka dahabka immersion: Ujeedada geeddi-socodka dahabka immersion waa in lagu shubo daahan nikkel-dahab leh midab deggan, dhalaal wanaagsan, daahan siman iyo alxan wanaagsan dusha PCB ah, kaas oo asal ahaan loo qaybin karaa afar marxaladood: pretreatment. ( Dereasing, micro-etching, activation, post-dipping), nikkel immersion, dahab immersion, daawaynta ka dib, (dhaqitaanka dahabka qashinka, DI dhaqida, qalajinta).
2. Daasacad lagu buufiyay rasaasta: Heerkulka eutectic ee ka kooban sunta rasaasta ayaa ka hooseeya kan daawaha aan sunta rasaasta lahayn.Qadarka gaarka ah wuxuu ku xiran yahay halabuurka daawaha aan rasaasta lahayn.Tusaale ahaan, eutectic ee SNAGCU waa 217 darajo.Heerkulka alxanku waa heerkulka eutectic oo lagu daray 30-50 digrii, iyadoo ku xidhan halabuurka.Hagaajinta dhabta ah, eutectic-ka hogaanka ahi waa 183 darajo.Awoodda makaanikada, dhalaalka, iwm. rasaasta ayaa ka fiican macdanta rasaasta.
3. Buufinta daasadaha ee bilaa rasaasta ah: Ledhku waxa uu wanaajin doonaa hawsha siliga daasadda ee habka alxanka.Siliga sunta rasaasta ayaa ka sahlan isticmaalka siligga aan sunta rasaasta lahayn, balse sunta rasaasta ayaa ah mid sun ah, mana wanaagsana jirka bini'aadamka haddii la isticmaalo waqti dheer.Daasadda aan macdanta "lead" lahayn waxay yeelan doontaa meel dhalaalaysa oo ka sareysa daasadda-lead, si ay kala-goysyada alxanka u noqdaan kuwo aad u xoog badan.
Habka gaarka ah ee habka wax soo saarka guddiga wareegga laba-geesoodka PCB
1. qodista CNC
Si loo kordhiyo cufnaanta shirka, godadka ku yaal guddiga wareegga laba-geesoodka ah ee PCB ayaa sii yaraanaya oo sii yaraanaya.Guud ahaan, looxyada pcb-da laba-geesoodka ah waxaa lagu qodaa mashiinnada qodista CNC si loo hubiyo saxnaanta.
2. Habka daloolka korantada
Habka daloolka dahaadhka ah, oo sidoo kale loo yaqaan godad bir ah, waa nidaam kaas oo gidaarka daloolka oo dhan lagu dhejiyo bir si qaababka korantada ee u dhexeeya lakabyada gudaha iyo dibadda ee guddiga wareegga daabacan ee laba-geesoodka ah ay koronto isku xiran karaan.
3. Shaashada daabacaada
Qalabka daabacaadda gaarka ah ayaa loo isticmaalaa qaababka wareegga daabacaadda shaashadda, qaababka maaskarada alxanka, qaababka calaamadaynta, iwm.
4. Daawaha daasadda-lead ee korantada
Electroplating Alloys-lead-lead waxay leedahay laba hawlood: marka hore, sida lakabka ilaalinta ka-hortagga daxalka inta lagu jiro korantada iyo etching;labaad, sida daahan alxanka ah ee looxa la dhammeeyey.Qalabyada sunta rasaasta ah ee korantada ku shaqeeya waa inay si adag u xakameeyaan qubayska iyo xaaladaha habsocodka.Dhumucda lakabka dahaadhka dahaadhka ee sunta rasaasta waa in ka badan 8 microns, iyo gidaarka daloolku waa inaanu ka yarayn 2.5 microns.
looxa wareegga daabacan
5. Cuncun
Marka loo isticmaalo daawaha-lead-ka-lead sida lakab iska caabin ah si loo farsameeyo guddi laba-geesood ah iyadoo loo marayo habka korantada etching qaabaysan, xal koloriin ah oo naxaas ah oo etching ah iyo xal ferric chloride etching ah lama isticmaali karo sababtoo ah waxay sidoo kale daxaleeyaan daaha daasadda-lead.Habka xoqitaanka, "dhinaca xoqidda" iyo ballaarinta dahaarka ayaa ah arrimo saameeya xoqitaanka: tayada
(1) Daxalka dhinaca.Daxalka dhinacku waa ifafaale quusitaanka ama quusta cidhifyada kirishbooyada oo ay keento xoqin.Inta uu le'eg yahay daxalka dhinacku wuxuu la xiriiraa xalalka etching, qalabka iyo xaaladaha habka.Daxalka garabku wuu yaraadaa.
(2) Daahan waa la ballaariyay.Balaadhinta dahaarka ayaa sabab u ah dhumucda dahaarka, taas oo ka dhigaysa ballaca dhinac ka mid ah siliggu inuu dhaafo ballaca saxanka hoose ee la dhammeeyey.
6. Dahab dahab ah
Dajinta dahabku waxay leedahay koronto heer sare ah, iska caabin yar oo xasilloon iyo iska caabin aad u fiican, waana alaabta ugu fiican ee dahaadhka ee daboolka looxa wareegyada daabacan.Isla mar ahaantaana, waxay leedahay xasillooni kiimiko oo heer sare ah iyo alxan, waxaana sidoo kale loo isticmaali karaa sidii daaha u adkaysta, alxanka iyo ilaalinta dusha PCB-yada.
7. dhalaalid kulul iyo heerka hawo kulul
(1) Kulul dhalaali ah.pcb-da ku dahaaran Sn-Pb alloy waxa lagu kululeeyaa meel ka sarraysa barta dhalaalka ee Sn-Pb alloy, si Sn-Pb iyo Cu ay u sameeyaan xarun bir ah, si dahaarka Sn-Pb uu u noqdo mid cufan, dhalaalaya oo aan lahayn biinhole, iyo caabbinta daxalka iyo solderability ee daahan ayaa la wanaajiyey.galmadaKulul-kulul inta badan la isticmaalo glycerol kulul-dhalaalid iyo kulayl-kulul infrared.
(2) Heerarka hawada kulul.Waxa kale oo loo yaqaan buufinta daasadda, looxa wareegga daabacan ee maaskaro-dahaarka leh waxaa lagu simayaa qulqulka hawo kulul, ka dibna ku duulaya barkadda alxanka dhalaalaysa, ka dibna u dhex mara labada mindiyo ee hawada si ay u afuufaan alxanka xad-dhaafka ah si aad u hesho dhalaal, lebis, siman. dahaarka alxanka.Guud ahaan, heerkulka qubayska alxanka waxaa lagu xakameynayaa 230 ~ 235, heerkulka mindida hawada waxaa lagu xakameynayaa korka 176, waqtiga alxanka 5-8s, dhumucda daahan waxaa lagu xakameynayaa 6 ~ 10 microns.
Guddi Wareeg oo Daabacan oo Laba-dhinac ah
Haddii PCB-ga looxa wareegga laba-geesoodka ah la xoqo, dib looma warshadeyn karo, tayada wax-soo-saarkeeduna waxay si toos ah u saameyn doontaa tayada iyo qiimaha alaabta ugu dambeysa.
