Camptech Circuits

For over 40 years, electronics manufacturers have trusted and relied on Camptech II Circuits’ expertise and production capabilities to manufacture their printed circuit boards. Whether your PCB is a simple one layer design or you require a multilayer board with controlled impedance and stacked microvias built, you can depend on us to manufacture your circuit boards with affordable pricing.

Camptech’s PCB Manufacturing Capabilities


Delivery


  • 2 to 10 days for prototypes
  • 5 days to 4 weeks for production

PCB Types


Silkscreen


  • White
  • Black

Soldermask


  • Solder mask registration tolerance – up to +/-0.002”
  • Minimum width of solder mask bridge: 4mil (Green), 5mil (other color); 8 mil on copper area

Soldermask colors

  • Red
  • Blue
  • Black
  • White
  • Yellow
  • Custom colors
  • Peelable Mask

Soldermask types

  • Liquid Photo Imageable (LPI)
  • Laser Direct Imaging (LDI)

Aspect Ratio


  • 12:1
  • The Aspect Ratio is defined as the scale of board thickness compared to the diameter of the drilled via. If you have a board with a 0.24″ thickness and a via with a 0.02″ diameter, the aspect ratio is 12:1. The higher this ratio, the increased plating that will be around a via compared to inside the via.

    Laminate Materials


    Blind/Buried Vias


    • Minimum epoxy filled via hole diameter – 4 mil
    • Maximum aspect ratio for filled vias – 10:1
    • Epoxy fill types – conductive & non-conductive

    A blind via is a connection from an outer layer of a board to one or more inner layers without exiting out the opposite side of the board.
