Stackup library
Choose copper-layer allocation, build-up order and reference planes as one system.
4-layer HDI PCB stackup
A compact escape layer on each face. Evaluate 1+2+1 as candidate notation, then verify the actual escape and plane allocation.
Stackup library6-layer HDI PCB stackup
A first HDI option for moderate routing demand. Evaluate 1+4+1 as candidate notation, then verify the actual escape and plane allocation.
Stackup library8-layer HDI PCB stackup
Compare routing depth with build-up complexity. Evaluate 1+6+1 or 2+4+2 as candidate notation, then verify the actual escape and plane allocation.
Stackup library10-layer HDI PCB stackup
Make room for controlled-impedance routing. Evaluate 1+8+1 or 2+6+2 as candidate notation, then verify the actual escape and plane allocation.
Stackup library12-layer HDI PCB stackup
Balance interfaces and power domains. Evaluate 1+10+1 or 2+8+2 as candidate notation, then verify the actual escape and plane allocation.
Stackup library14-layer HDI PCB stackup
Plan the path from build-up to core. Evaluate 2+10+2 or 3+8+3 as candidate notation, then verify the actual escape and plane allocation.
Stackup library16-layer HDI PCB stackup
Budget both plane layers and via corridors. Evaluate 2+12+2 or 3+10+3 as candidate notation, then verify the actual escape and plane allocation.
Stackup library18-layer HDI PCB stackup
Keep the fabrication sequence visible. Evaluate 2+14+2 or 3+12+3 as candidate notation, then verify the actual escape and plane allocation.
Stackup library20-layer HDI PCB stackup
Separate layer count from HDI order. Evaluate 2+16+2 or 3+14+3 as candidate notation, then verify the actual escape and plane allocation.
Stackup library24-layer HDI PCB stackup
Qualify the complete high-layer-count construction. Evaluate 2+20+2 or 3+18+3 as candidate notation, then verify the actual escape and plane allocation.
Stackup library1+N+1 HDI stackup
One build-up layer on each side of an N-layer core provides a simple starting point for HDI routing.
Stackup library2+N+2 HDI stackup
Two build-up layers per side provide another escape depth and introduce another set of interconnect and process choices.
Stackup library3+N+3 HDI stackup
Three build-up layers per side can resolve deeper package escape, with more process steps and a stronger need for early factory involvement.
Stackup libraryAny-layer HDI and ELIC
Any-layer HDI offers interconnection through successive microvia structures throughout the board. The name does not remove physical or qualification limits.
Stackup librarySymmetric HDI stackups and copper balance
Mechanical symmetry involves dielectric, copper and pattern distribution. Matching the number of layers above and below the center is only the starting point.
Stackup libraryAllocating signal, power and ground layers
Start from return paths and power delivery, then assign signal layers. The remaining copper count is not automatically usable routing capacity.
Stackup libraryHDI board thickness and dielectric planning
Finished board thickness combines copper, pressed dielectric, mask and other construction details. A thickness target must leave a feasible microvia geometry.
Stackup libraryHigh-layer-count HDI PCB: supplier and stackup review
Evaluate 22–52-layer proposals through routing demand, thickness, interconnect geometry and qualification evidence. A layer-count claim alone does not establish a manufacturable HDI process.
