Custom PCB Manufacturing FAQs
Q1: What is the difference between PCB manufacturing and PCBA?
A: PCB manufacturing (fabrication) focuses on producing the physical bare board—including etching copper layers, drilling holes, and applying solder mask based on layout designs. PCBA (Assembly) involves mounting and soldering electronic components onto that fabricated bare board.
Q2: What is the maximum layer count and structure types you can fabricate?
A: We support rigid PCBs from 1 to 64 layers, alongside advanced flexible circuits (flex PCBs), rigid-flex boards, and complex Any-Layer HDI architectures.
Q3: What are your capabilities regarding fine-line etching and laser microvias?
A: We master ultra-fine line widths and spacings down to 1.8 mil (approx. 0.045 mm) and laser-drilled microvias down to 3 mil (approx. 0.075 mm) to support high-density routing.
Q4: How do you handle high-frequency materials for RF and microwave applications?
A: We utilize specialized low-loss laminates such as Rogers and Isola series, ensuring strict dielectric thickness control and minimal signal attenuation for high-frequency systems.
Q5: What surface finish options are available for bare PCBs?
A: We provide a full spectrum of surface finishes including ENIG, ENEPIG, Immersion Silver, lead-free HASL, and OSP to ensure long-term shelf life and superior soldering reliability.
Q6: What is your maximum copper weight capacity for heavy-current boards?
A: We support heavy copper fabrication up to 28 oz, making our bare boards ideal for high-power distribution, automotive EV systems, and industrial power supplies.
Q7: What quality control and testing methods are applied before delivery?
A: Every bare board undergoes 100% automated optical inspection (AOI), flying probe electrical testing, and rigorous impedance verification to ensure zero defects.
Q8: What drilling accuracy and aspect ratios can your smart factory achieve?
A: Our high-precision CNC and laser drills achieve positioning accuracy of up to ±1 mil (±0.025 mm) and support high-aspect-ratio plating up to 40:1 for multi-layer vertical interconnections.
Q9: Which international manufacturing and safety standards do you comply with?
A: Our production ecosystem complies with ISO 9001, ISO 14001, ISO 13485, IATF 16949, UL certifications, as well as strict RoHS and REACH environmental regulations.
Q10: What information or files are required to get a DFM review and quotation?
A: You need to provide standard Gerber files (RS-274-X format), an ODB++ package, a detailed drill file, and a fabrication drawing specifying layer stack-up, material preferences, and surface finish requirements.
