PCBExpress® Quickturn PCB Construction Detail


PCBExpress® Quickturn multilayer printed circuit boards offer you the best value for up to 100 pieces per order. Available in 2- to 6-layer PCB construction, all our PCBExpress Quickturn multilayer printed circuit boards are manufactured on-site at our headquarters in the USA.

Standard 2 Layer PCB Construction (0.062")

Thickness
(Inches)
Tolerance (+/-)
Layer 1 0.0017 0.0004 0.5 oz foil plated to approximate*
Laminate Core 0.0580 0.0005 Dielectric Constant 4.5 (+/- 0.10)
Layer 2 0.0017 0.0004 0.5 oz foil plated to approximate*
Overall 0.061 0.006

* Plating target is minimum of 0.0008" in the hole with approximately 0.001" on the surface. Design can influence the plated thickness, generally thinner on ground planes and thicker on signals.
