PCB proto

Fast & Easy PCB Prototyping Service for Bare Board or Assembled PCB’s

Made in Europe

Eurocircuits’ PCB Proto service offers customers a simple and no fuss fast Prototyping service. Your data is analysed and once we have checked that your data complies with our technical spec, the board goes in production.

We ignore the options typically needed for series production (peelable masks, via-filling, specific finish, soldermask colours, etc.) as these are not usually crucial for making a functional prototype.

This way we can achieve fast deliveries at attractive prices.

  1. Subject to design meeting our PCB proto manufacturing and assembly specification and component availability.
  2. The price cannot be automatically calculated for a PCB containing more than 200 BOM lines or 1000 component placements, our engineering department will evaluate and send you an offer usually within 24 hours.
  3. These conditions are available in our calculator/Visualizer and will only be confirmed in our order confirmation.
