Frequently Asked Questions
What minimum trace width, spacing, and aspect ratio tolerances can your manufacturing lines sustain?
For high-density interconnect (HDI) designs, our production facilities reliably manufacture fine-line traces with widths and spacings down to 3 mils (0.075 mm) in high-volume runs. Our advanced laser-drilling processes achieve an aspect ratio of up to 10:1 for standard through-holes, and 1:1 for blind and buried microvias. This level of precision allows layout engineers to safely route high-pin-count BGA packages with tight pitch configurations down to 0.4 mm without sacrificing signal routing channels.
What surface finish options are available to balance long shelf-life with flat pad planarity for fine-pitch SMT assembly?
- ENIG (Electroless Nickel Immersion Gold): The industry standard for fine-pitch surface mount devices (SMD), providing an exceptionally flat surface pad and excellent shelf life.
- HASL / Lead-Free HASL (Hot Air Solder Leveling): A highly cost-effective option for robust, standard through-hole and low-density surface-mount assemblies.
- OSP (Organic Solderability Preservatives) & Immersion Silver/Tin: Ideal for high-speed signal designs where minimizing the “skin effect” losses introduced by nickel barriers is a priority.
Which specialized high-frequency and thermal substrate materials do you keep in stock?
- High-Speed/Low-Loss: Premium dielectrics (such as Rogers, Megtron 6, and Isola families) engineered for minimal dissipation factors (Df) and stable dielectric constants (Dk) into the millimeter-wave bands.
- Thermal Management: Metal-core PCBs (MCPCBs) featuring integrated aluminum or copper substrates, designed specifically to dissipate heat out of high-power LED systems and power converter circuits.
- Flex-Rigid: Specialized polyimide substrates configured for dynamic mechanical bending or tight, space-constrained architectural enclosures.
What electrical and automated inspection protocols are applied to bare circuit boards before shipping?
- AOI (Automated Optical Inspection): Scans every copper layer against your original Gerber/ODB++ design files to detect any trace shorts, cuts, or deviations before mask application.
- Flying Probe / Electrical Testing: Validates netlist continuity and isolation across every test point and pad configuration on the outer layers to completely rule out hidden opens or short circuits.
