“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 or 5 boards in 2 to 7 days days - 2 or 4 layers
Fully-finished with 2 solder-masks and 1 silk-screen
Lead-free finish (our 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 leadfree 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)
