RoHS Certified High-Density PCB Anti-ESD Protection Tailored for Wireless Network
Why Choose This High-Density PCB?:
1.Ultra-high integration & miniaturization – Fine traces, laser microvias, and blind/buried vias maximize wiring in limited space.2. Superior signal integrity – Impedance controlled, low-loss design ideal for high-speed/RF/wireless applications.
3. Excellent reliability – High-Tg/thermal stable substrates and ENIG finish ensure durability and consistent performance.
4. Fully customizable – Tailored layers, materials, and finishes to match your device specs and assembly needs.
Production Flow:
1.Material Preparation: Select high-performance core boards, prepregs, and copper foils suitable for HDI.
2. Inner Layer Circuit Fabrication: Use laser direct imaging (LDI) and etching to make fine inner-layer circuits.
3. Automatic Optical Inspection (AOI): Check inner-layer circuits for defects.
4. Lamination: Stack core boards, prepregs, and outer copper foils under high temperature and pressure.
5. Laser Drilling: Drill micro-vias for interlayer connection (key process for HDI).
6. Electroless Copper Plating & Electroplating: Deposit copper on via walls and circuits to achieve conduction.
7. Outer Layer Imaging & Etching: Form fine outer-layer circuits.
8. Solder Mask Application: Apply green/blue solder mask to protect circuits.
9. Surface Finishing: Apply treatments such as ENIG, immersion tin, or OSP.
10. Silk Screen & Marking: Print logos and component labels.
11. Electrical Test & Final Inspection: Test open/short circuits and inspect appearance.
12. Routing & Packaging: Separate boards and pack for delivery.
FAQ:
1.Q:How many layers can your circuit boards provide?
A:We typically provide 1-30 layer boards, and in special cases, we can stack more layers.
2. Q:Do your circuit boards support customization?
A:Yes, we support customized designs. You can send us your Gerber files and BOM list, and we will provide you with an accurate quote based on the information and market conditions.
3. Q:What do Gerber files typically contain?
A:Normally Gerber files Include:PCB Types,Product thickness, Ink color, Surface treatment process and If SMT processing is required, component BOM and tag drawing are also required.
4. Q:What is your minimum order quantity for PCB boards?
A:Our minimum order quantity is 1 piece(5 square meters),the larger the quantity, the bigger the discount.
5. Q:Do you have relevant certification certificates to support this?
A:We hold numerous important certifications, including ISO, UL, CE, and RoHS. All products undergo rigorous quality testing.
6. Q:What payment method do you usually use?
A:For small orders, samples, or urgent payments, we accept Western Union. For large orders, we recommend T/T, which ensures the safety of both parties.
