JLCPCB
JLCPCB is a Chinese PCB manufacturer.
What is the maximum number of layers supported by JLCPCB for standard production?
“JLCPCB supports up to 32 layers in standard production. Layers from 1 to 6 offer the optimal balance between cost, lead time, and reliability. For designs exceeding 10 layers, we recommend submitting the stack-up diagram for engineering review prior to ordering to ensure manufacturability and controlled impedance performance.”
View in the company profileDoes JLCPCB provide impedance control, and what tolerance can be achieved?
“Yes, JLCPCB offers impedance control for multi-layer boards. The standard tolerance is ±10%. Tighter tolerance of ±5% is available upon special request, which requires controlled dielectric materials, precise stack-up design, and may involve additional verification.”
View in the company profileWhat are the key differences in manufacturing capabilities between standard and advanced options?
“Standard options include mechanical drilling, regular trace/space, and common surface finishes with faster lead times. Advanced options such as blind/buried vias, HDI (laser vias), heavy copper (up to 3oz), and tight impedance control provide higher design density and performance but typically require DFM review and may increase both cost and production time.”
