FAQs
4-Layer PCB Questions
What is the standard 4-layer stackup?
Signal-Ground-Power-Signal with 1.6mm total thickness. This provides good impedance control and EMI shielding. Custom stackups available for specific impedance or thickness requirements.
When should I use 4 layers instead of 2?
When you need: controlled impedance, dedicated power/ground planes, better EMI performance, or more routing space. Most designs with BGA components or high-speed signals (>50MHz) benefit from 4 layers.
How much more expensive is 4-layer vs 2-layer?
Typically 40-60% more than 2-layer for the same board size. The exact premium depends on specs. Use our instant quote to compare.
Can I get impedance control on a 4-layer board?
Yes, and we recommend it for any high-speed design. ±8% tolerance standard. TDR test report included at no extra charge when impedance is specified.
