2 Layer PCB

2 Layer PCB

Double-plated printed circuit board is a printed circuit with two layers of copper with metallized holes that can have a soldering mask or two soldering masks or it can be without a soldering mask and can have one or two silkscreen.

The steps that a two-layer board goes through in manufacturing are:

  • Laminate cutting
  • Drilling
  • Metallization
  • Image transfer
  • Corrosion
  • Optical testing (AOI)
  • Solder mask
  • Silkscreen
  • Finishing
  • Electrical test
  • Mechanical processing

For a multilayer printed circuit with a specific stack-up, it must be taken into account that the internal tracks with controlled impedance are shielded

Printed circuit soldermask

Soldermask is generally green in color but can have different colors: green, red, blue, white, black. Only the outer layers need to be covered with solder mask, the inner copper layers are protected by the adjacent substrate layers.

For microwave printed circuits, transmission lines can be laid out in a planar form, such as stripline or microstrip, with dimensions carefully controlled
