If your design falls outside these standard design rules, we can still probably meet your technical requirements. However, we are unable to provide instant quotations for boards that fall outside these requirementsand need at least 1 working day to provide a quotation. For exceptionally stringent designs, we may ask to see your CAM files before quoting.

Our extended manufacturing capabilities include printed circuit boards up to 20 layers, track and clearence down to 3 mil, impedance controlled circuit boards, non-standard board thicknesses and materials. Please call us for a quote.

We are also able to provide exceptionally competitive prices for orders when the total area of all boards is > 20 sq meters (1-2 layers) and > 5 sq meters (4-10 layers). Please contact us for a special price.
