FAQ

Frequently Asked Questions

What is BELI's maximum PCB layer count and technology range?
BELI manufactures boards up to 42 layers across rigid, flexible, and HDI constructions, including impedance-controlled designs (±10%) and high-frequency materials such as Rogers.
What is the minimum line width and spacing?
3.0/3.0 mil for inner layers and 4.0/4.0 mil for outer layers, with a minimum hole diameter of 4 mil and aspect ratios up to 11:1.
What is the smallest component and BGA pitch your SMT lines can place?
Components down to 0201/01005, BGAs down to 0.4 mm ball pitch, and lead pitches down to 0.35 mm — at ±0.03 mm placement precision.
What PCB materials do you support?
FR-4, High-Tg FR-4, halogen-free laminates, and high-frequency substrates including Rogers, Arlon, Taconic, and Nelco, plus Polyimide (flex), Aluminum, and Ceramic.
What is your monthly SMT capacity and board size range?
Approximately 52 million component placements per month. Board sizes from 45 × 45 mm up to 680 × 500 mm, with board thicknesses from 0.4 to 5 mm for assembly.
