PCB proto – the idea!

Eurocircuits offers its customers a simple, no fuss, fast prototyping service. Your data is analyzed 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.

What do you get?

  • 1 ,2, 3, 4 or 5 PCB’s in 2 or 3 working days – 2 or 4 layers
  • Fully-finished with 2 solder-masks and 2 silk-screen
  • Lead-free finish (choice of electroless nickel immersion gold or lead-free HAL)
  • FR-4 – RoHS compliant material optimised for lead-free soldering with standard build-up (see also our blog about materials and lead-free soldering)
  • No tooling charges. No minimum order charge.
  • 100% manufacturability check prior to production
  • PCB Configurator to check and upload design parameters before pricing or
  • PCB Visualizer and PCB Checker analysis before you place your order. (from your order basket)

How to get prices and place orders?

  • Log in and go to Calculate and PCB proto.
  • Select Price calculator to enter all details manually or Analyse your data to get PCB Configurator to analyse your data and enter the design parameters into the Price calculator menu.
  • Enter quantity and delivery required plus number of layers and dimensions.  That’s it – nothing more. You see the price at once.
  • Attach files and place your order in the shopping basket .
  • The PCB Visualizer analysis starts running right away.
  • Open PCB Visualizer to check the results, and if everything is ok, checkout to place your order.

How do we keep PCB proto prices down?

Eurocircuits are specialist manufacturers of prototype and small batch PCBs.  We are experts in order-pooling.  Placing different orders on a standard production pooling panel minimizes set-up and production costs so you get good prices and no tooling charges.  For “PCB proto” we use newly-developed automated design analysis algorithms.  These allow us to cut board verification costs and still do 100% check on your data before manufacture to make sure that you get the boards you want.
