Tattaunawa akan tsarin cika rami na lantarki na PCB

Girman samfuran lantarki yana ƙara ƙarami kuma yana ƙara ƙarami, kuma tari kai tsaye ta hanyar ta hanyar makafi hanya ce ta ƙira don babban haɗin kai. Don yin aiki mai kyau na tara ramuka, da farko, ya kamata a yi la'akari da kasan ramin da kyau. Akwai hanyoyin masana'antu da yawa, kuma tsarin cika rami na electroplating shine ɗayan wakilan.
1. Amfanin electroplating da rami cika:
(1) Yana dacewa da ƙirar ramukan da aka tattara da ramuka akan farantin;
(2) Inganta aikin lantarki da taimakawa ƙira mai girma;
(3) yana taimakawa wajen zubar da zafi;
(4) Ramin filogi da haɗin wutar lantarki an kammala su a mataki ɗaya;
(5) Ramin makaho yana cike da jan ƙarfe na lantarki, wanda ke da inganci mafi girma kuma mafi inganci fiye da mannen ɗabi'a.
 
2. Ma'aunin tasiri na jiki
Siffofin jiki waɗanda ke buƙatar yin nazari sun haɗa da: nau'in anode, nisa tsakanin cathode da anode, yawa na yanzu, tashin hankali, zafin jiki, mai gyarawa da yanayin motsi, da sauransu.
(1) Nau'in Anode. Idan aka zo ga nau’in anode, ba komai ba ne illa anode mai narkewa da anode mai narkewa. Anodes masu narkewa galibi ƙwallayen jan ƙarfe ne da ke ɗauke da phosphorus, waɗanda ke da haɗari ga laka na anode, suna gurɓata maganin plating, kuma suna shafar aikin maganin plating. Insoluble anode, mai kyau kwanciyar hankali, babu bukatar anode kiyayewa, babu anode laka tsara, dace da bugun jini ko DC electroplating; amma amfani da additives ne in mun gwada da girma.
(2) Cathode da anode tazara. Tsarin tazara tsakanin cathode da anode a cikin tsarin cika rami na electroplating yana da matukar mahimmanci, kuma ƙirar nau'ikan kayan aiki daban-daban shima ya bambanta. Ko ta yaya aka tsara shi, bai kamata ya keta dokar farko ta Farah ba.
(3) Tadawa. Akwai nau'ikan motsa jiki da yawa, gami da jujjuyawar injina, girgizar wutar lantarki, girgiza pneumatic, motsawar iska, kwararar jet da sauransu.
Don cika rami na lantarki, gabaɗaya an fi son ƙara ƙirar jet bisa tsarin silinda na jan ƙarfe na gargajiya. Lamba, tazara da kusurwar jets a kan bututun jet duk abubuwan da dole ne a yi la'akari da su a cikin ƙirar silinda na jan karfe, kuma dole ne a yi babban adadin gwaje-gwaje.
(4) Yawan yawa da zafin jiki na yanzu. Ƙananan yawa na yanzu da ƙananan zafin jiki na iya rage yawan adadin jan ƙarfe a saman, yayin da samar da isasshen Cu2 da haske a cikin pores. A ƙarƙashin wannan yanayin, ana haɓaka ikon cika ramin, amma kuma an rage tasirin plating.
(5) Mai gyarawa. Mai gyarawa shine muhimmiyar hanyar haɗi a cikin tsarin lantarki. A halin yanzu, bincike game da cika rami ta hanyar lantarki ya fi iyakance ga cikakken allo na lantarki. Idan an yi la'akari da cika ramin ƙirar ƙira, yankin cathode zai zama ƙanana sosai. A wannan lokacin, ana sanya buƙatu masu girma sosai a kan daidaiton fitarwa na mai gyarawa.Ya kamata a zaɓi daidaitattun kayan aikin daidai da layin samfurin da girman ta hanyar rami. Ƙananan layi da ƙananan ramuka, mafi girma madaidaicin buƙatun don gyara ya kamata ya kasance. Gabaɗaya, yana da kyau a zaɓi mai gyara tare da daidaiton fitarwa a cikin 5%.
(6) Waveform. A halin yanzu, ta fuskar waveform, akwai nau'ikan electroplating da kuma cika ramuka: pulse electroplating da direct current electroplating. Ana amfani da gyaran gyare-gyaren gargajiya don yin platin yanzu da kuma cika rami, wanda ke da sauƙin aiki, amma idan farantin ya fi girma, babu wani abu da za a iya yi. Ana amfani da PPR rectifier don bugun wutar lantarki da cika rami, kuma akwai matakan aiki da yawa, amma yana da ƙarfin sarrafawa don alluna masu kauri.
