Q1: What services are included in PCB design and layout?

A1: Our full-service package includes schematic capture (converting circuit concepts to digital schematics), multilayer PCB layout (component placement/routing), DFM analysis (ensuring manufacturability), signal integrity/impedance control (for high-speed designs), thermal analysis (for high-power components), and delivery of production-ready files (Gerber, BOM, pick-and-place).

Q2: Can China 365PCB handle high-speed and high-frequency PCB design?

A2: Yes, we specialize in high-speed (≥1 Gbps) and high-frequency (≥2 GHz) designs. Our engineers use simulation tools (ANSYS SIwave) to optimize trace routing, control impedance (50Ω/75Ω/100Ω), reduce crosstalk, and minimize signal reflection. We also use high-frequency substrates like Rogers to ensure stable performance for telecom, 5G, and RF applications.

Q3: What file formats do you deliver after PCB design?

A3: We deliver industry-standard files ready for manufacturing: Gerber files (RS-274X, the global standard for PCB fabrication), drill files (for hole positioning), BOM (with component part numbers/suppliers), pick-and-place files (for SMT assembly), and a DRC report (verifying design rule compliance). We can also provide step files for mechanical enclosure matching.

Q4: How long does a typical PCB design project take?

A4: Timeline depends on design complexity: simple single/double-layer PCBs take 3–5 business days; 4–8 layer multilayer designs take 5–7 days; complex HDI or high-frequency designs (10+ layers) take 7–10 days. We offer rush service for urgent projects, which can shorten timelines by 20–30%.

Q5: Do you offer design revisions and support during prototyping?

A5: Yes, we provide up to 2 free design revisions to address functional or manufacturing feedback. Our team also offers ongoing support during prototyping—we review test results, troubleshoot issues (e.g., EMI, thermal hotspots), and adjust the design to ensure it meets your performance and assembly requirements.
