Layer stackup
A multilayer PCB stackup defines copper layers, dielectric thickness, prepreg, core material, ground planes and power planes. Early stackup confirmation helps control impedance, board thickness and drilling structure.

Multilayer PCB Design Guide
Multilayer PCB design requires careful stackup planning, material selection and manufacturing rule review to support signal quality, power delivery and production stability.

Material selection
FR4, High Tg and halogen-free materials are selected according to thermal performance, reliability, compliance and application environment. High layer count designs often require closer material and lamination review.
Signal integrity
Controlled impedance, return paths, plane reference, via transitions and trace spacing influence high-speed performance. Designers should provide impedance requirements and critical net information when available.
Manufacturing considerations
Manufacturing review should cover minimum trace and spacing, hole size, annular ring, copper balance, solder mask clearance, panelization needs and final inspection requirements.
Related applications
Multilayer PCB is common in industrial electronics, medical equipment, automotive control, IoT gateways, power electronics and communication systems.
Engineering review first
YBCPCB reviews PCB files, material requirements, stackup notes and inspection needs before production planning.
