A cikin tsarin samar da PCB, tsarin jiyya na farfajiya abu ne mai mahimmanci mataki. Ba wai kawai ya shafi bayyanar PCB ba, amma kuma yana da alaƙa kai tsaye game da aikin, aminci da ƙwararraki na PCB. Tsarin jiyya na farfajiya na iya samar da Layer Layer don hana lalata tagulla, kuma inganta siyar da aikin siyarwa, da kuma samar da kyawawan hanyoyin lantarki. Mai zuwa bincike ne na bincike da yawa na gama gari gama gari a cikin samarwar PCB.
一
Tsarin iska mai zafi (HASL) fasahar magani na al'ada wacce ke aiki ta hanyar narkar da PCB zuwa "Plearize" saman don ƙirƙirar ɗakunan ƙarfe. Tsarin Hasl yana da tsada-tsada kuma ya dace da masana'antar PCB, amma yana iya samun matsaloli tare da katako mara kyau da kuma rigunan ƙarfe da ba su dace ba.
二 .enig (Nickel Nickel Zinare)
Wuta nickel zinare (enig) tsari ne wanda ke adana nickel da Layer Layer a saman PCB. Na farko, an tsabtace farfajiya ta kuma an sanya shi, to, an sanya bakin ciki na Nickel na sinadarai, kuma a ƙarshe aka kunna Layer na zinari, sannan a ƙarshe wani Layer na gwal yana kan layi na nickel. Tsarin Enig yana samar da kyakkyawan juriya da kuma sanadin juriya kuma ya dace da aikace-aikace tare da bukatun aminci, amma farashin yana da girma.
三, Zinariya sunadarai
Ansical Zinadaran adonin karfe na bakin ciki kai tsaye akan PCB surface. Wannan tsari ana amfani dashi sau da yawa a aikace-aikacen da ba sa bukatar sojoji, irin su mitar rediyo (RF) da da'irar microcove, saboda jingina na bayarwa kyakkyawan aiki da jingina. Kayan aikin zinari na ƙasa da Elig, amma ba kamar Wuri mai tsayawa bane kamar yadda Enig.
, OSP (Fim na kariya)
Fim na kariya (OSP) tsari ne wanda yake samar da wani fim na bakin ciki na bakin ciki a saman jan karfe don hana jan ƙarfe daga oxdizing. OSP yana da tsari mai sauƙi da tsada, amma kare shi yana ba da rauni kuma ya dace da ajiya na ɗan lokaci da amfani da kwastomomi.
五, wahalar zinare
Zinariya mai wuya tsari ne wanda ke adana kauri zinare a kan PCB surface ta hanyar electroplating. Zinariya mai wuya ita ce mafi jingina da zinariya kuma ya dace da masu guba waɗanda ke buƙatar pluggging akai-akai ko pbs da aka yi amfani da su cikin matsanancin mahalli. Kudin zinariya mai wuya fiye da zinariya sunadarai amma yana samar da mafi kyawun kariya na dogon lokaci.
, Azurfa azurfa
Azurfa na nutsuwa tsari ne don sanya ido a saman PCB. Azurfa tana da kyau da kyau da kuma yin magana, sanya ta dace da shirye-shiryen da ke bayyane. Kudin tsarin aikin nutsuwa yana matsakaici, amma murfin azurfa yana da sauƙi mai sauƙi kuma yana buƙatar ƙarin matakan kariya.
七, tin intRion tin
Ginin nutsuwa shine tsari don ajiye wani ƙaramin a saman PCB. Tsarin tin yana samar da kaddarorin sayar da abinci da kuma wasu juriya na lalata. Tsarin gyaran n m yake da arha, amma yana da sauƙin oxidized kuma yawanci yana buƙatar ƙarin Layer mai kariya.
, Jigon-free Hasl
Hasl-kyauta Hasl shine tsarin da ake amfani da Hasl wanda ke amfani da Tin-Free / Azurfa / jan ƙarfe sutthon don maye gurbin tin gardat / jagorar Alloy. Tsarin tsari na Hasl na kyauta yana ba da irin wannan aikin zuwa Hasl na gargajiya amma ya cika bukatun muhalli.
Akwai matakai daban-daban na jiyya a cikin PCB na PCB, kuma kowane tsari yana da fa'idodi na musamman da yanayin aikace-aikace. Zabi tsarin magani da ya dace na buƙatar la'akari da yanayin aikace-aikace, buƙatun wasan kwaikwayon, kasafin kuɗi da ƙa'idar kariya ta ƙwaƙwalwar muhalli ta PCB. Tare da ci gaban fasaha na lantarki, sabon maganin jiyya na ci gaba da fitowa, samar da masana'antun masana'antun tare da ƙarin zabi don saduwa da musayar kasuwa.
