Каковы некоторые преимущества и недостатки перехода от двухслойной печатной платы с компонентами на одной стороне?, к четырехслойной печатной плате с компонентами на обеих сторонах?

Two-layer is cheaper, while the four layers will cost more. Так как

  • 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 сборка 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 (чип резисторы & конденсаторы) 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. Таким образом, the user-friendly weight of PCB will suit portable equipment.
