Yi amfani da sanannen CCL na duniya, Amfani: Ingantaccen aminci, tsawon rai da sanannen aiki. Haɗarin rashin yin haka: Yin amfani da zanen gado mara kyau zai rage rayuwar samfurin sosai, kuma a lokaci guda, ƙarancin kayan aikin injiniya na takardar yana nufin cewa hukumar ba zata yi kamar yadda ake tsammani ba a ƙarƙashin yanayin da aka haɗa, misali: babban haɓakawa. Properties na iya haifar da delamination, bude da'ira da warping buckling matsaloli, da kuma raunana lantarki kaddarorin na iya haifar da matalauta impedance aiki. Kayayyakin masana'antar ABIS PCB duk sun fito ne daga sanannun masu samar da hukumar gida da na waje, kuma sun kai dogon lokaci dabarun haɗin gwiwa tare da masu kaya don daidaita wadatar. 4. Yi amfani da tawada mai inganci Fa'idodi: Tabbatar da ingancin bugu na allon kewayawa, inganta amincin haifuwar hoto, da kare kewaye. Hadarin rashin yin haka: Rashin ingancin tawada na iya haifar da mannewa, juriya da matsalolin tauri.Duk waɗannan matsalolin na iya haifar da abin rufe fuska don cirewa daga allon kuma a ƙarshe ya haifar da lalata da'ira na jan karfe.Ƙananan kaddarorin rufewa na iya haifar da gajerun da'irori saboda ci gaba da wutar lantarki na bazata.
5. Ya wuce ƙa'idodin tsabta na ƙayyadaddun IPC Amfani: Ingantaccen tsabtar PCB yana inganta aminci. Hadarin da rashin yin haka: Ragowar kan jirgin, solder ginawa zai iya gabatar da wani hadari ga solder mask, ionic saura iya haifar da lalata da solder surface da hadarin kamuwa da cuta wanda zai iya haifar da AMINCI al'amurran da suka shafi (mummunan solder gidajen abinci / lantarki kasawa). ), kuma daga ƙarshe ƙara yuwuwar gazawar gaske.

6. Tsananin sarrafa rayuwar sabis na kowane jiyya na saman Fa'idodi: Solderability, amintacce, da rage haɗarin kutsawa danshi. Hadarin da rashin yin haka: Solderability al'amurran da suka shafi na iya faruwa saboda metallographic canje-canje a cikin surface gama na mazan allon, da kuma danshi kutsawa iya haifar da delamination, ciki yadudduka da rami ganuwar a lokacin taro da / ko ainihin amfani Separation (bude kewaye), da dai sauransu shan. tsarin fesa tin na saman a matsayin misali, kauri na fesa tin shine ≧1.5μm, kuma rayuwar sabis ya fi tsayi. 7. High quality toshe rami Amfani: Babban ramukan toshewa a cikin masana'antar PCB zai rage haɗarin gazawar yayin taro. Hadarin rashin yin haka: Ragowar sinadarai daga aikin nutsewar zinari na iya zama a cikin ramukan da ba su cika toshe ba, suna haifar da matsaloli kamar iyawar siyarwa.Bugu da kari, ana iya samun kwano da aka boye a cikin ramukan.Lokacin haɗuwa ko ainihin amfani, ƙwanƙolin gwangwani na iya fantsama da haifar da ɗan gajeren kewayawa. 8. Haƙuri na CCL ya dace da bukatun IPC 4101 ClassB / L Amfani: Tsantsan sarrafa kauri na dielectric Layer yana rage karkacewa daga aikin lantarki da ake tsammani. Hadarin rashin yin haka: Ayyukan lantarki bazai cika ƙayyadaddun buƙatu ba, kuma abubuwan da aka haɗa daga rukuni ɗaya na iya bambanta ko'ina cikin fitarwa/aiki. 9. Kula da hankali da juriya na siffofi, ramuka da sauran kayan aikin injiniya Fa'ida: Haƙuri mai ƙarfi da sarrafawa yana haɓaka ingancin girman samfur - ingantaccen dacewa, tsari da aiki. Hadarin rashin yin haka: Matsaloli a lokacin taro, kamar daidaitawa/mating (matsalolin tare da latsa-fit fil ana gano su ne kawai lokacin da taro ya cika).Bugu da ƙari, hawan cikin tushe kuma yana iya zama matsala saboda haɓakar ƙima.Dangane da ka'idodin aminci mai girma, haƙurin matsayi na rami ya kasance ƙasa da ko daidai da 0.075mm, haƙurin rami diamita shine PTH ± 0.075mm, kuma haƙurin siffar shine ± 0.13mm. 10. The kauri na solder mask ne lokacin farin ciki isa Fa'idodi: Ingantattun kayan kwalliyar lantarki, rage haɗarin kwasfa ko asarar mannewa, haɓaka juriya ga girgiza injin - duk inda ya faru! Hadarin rashin yin haka: Mashin bakin ciki na solder na iya haifar da mannewa, juriya da matsalolin tauri.Duk waɗannan matsalolin na iya haifar da abin rufe fuska don cirewa daga allon kuma a ƙarshe ya haifar da lalata da'ira na jan karfe.Ƙananan kaddarorin rufewa saboda bakin ciki abin rufe fuska na solder, na iya haifar da gajeriyar da'irori saboda ƙaddamarwa/arcing na bazata.
