片面にコンポーネントを備えた 2 層 PCB から移行することの利点と欠点は何ですか?, 両面にコンポーネントを備えた 4 層 PCB へ?

Two-layer is cheaper, while the four layers will cost more. なぜなら

  • There are twice as many layers to etchand then laminate.
  • It will take almost twice as much work, steps and materials to fabricate.
  • It will also take two アセンブリ passes for pick and place instead of one.
  • Anything manually placed through hole will also take one more pass for the second size.

Only drilling and 2 silkscreen and 2 solder resist will remain the same.

Compared to four layers, double sided

  • will allow a significant gain in component density.
Primary side taller stuff, large scale ICs and connectors
Secondary side low profile passives (チップ抵抗器 & コンデンサ) and perhaps low profile ICs and diodes, signal transistors
  • That will allow a smaller PCA footprint, so the PCA costs are saved in enclosure and overall size. したがって、, the user-friendly weight of PCB will suit portable equipment.
