Ta hanyar ramin rami na HDI PCB

A cikin babban nau'in PCB na sauri, sau da yawa ana amfani da PCB na Layer, kuma ta hanyar rami abu ne mai mahimmanci a ƙirar PCB da yawa. A cikin rami a cikin PCB an hada da sassa uku: rami, walda pad yankin kusa da rami da kuma yankin kadada ta ciki. Bayan haka, za mu fahimci babban mai sauri PCB ta hanyar matsalar rami da kuma buƙatun tsara.

Tasiri ta rami a HDI PCB

A cikin HDI PCB multilayay, da ke tsakanin shiga tsakanin Layer da wani Layer Layer da aka haɗa ta hanyar ramuka. Lokacin da mitar ƙasa da 1 GHZ, ramuka na iya taka rawa mai kyau dangane, kuma za'a iya watsi da shi da kuma shigar da aikin shiga ciki. Lokacin da mitar ya fi 1 GHZ, sakamakon tasirin tasirin fari a kan amincin siginar ba za a iya watsi da shi ba. A wannan gaba, rami na sama yana ba da dakatarwar hana matsalar watsawa, wanda zai haifar da tunani, jinkirtawa, hatsawa da sauran matsalolin tabbatar da alama.
