* 10 Layers Maximum for on-line price

If your design falls outside these standard design rules, we can still probably meet your technical requirements. However, our on-line price calculator will not provide accurate prices and we need at least 1 working day to provide a special 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 4 mil, impedance controlled circuit boards, blind and buried vias, gold fingers, non-standard board thicknesses and materials. Please call us for a quote.

We are able to provide exceptionally competitive prices for orders larger than our on-line price calculator can handle. ( > 20 sq meters ). Please contact us for a special price.
