8 LAYER PRINTED CIRCUIT BOARD
Founded in 2010, Shenzhen Huashengxin Circuit is a professional manufacturer for printed circuit boards. Huashengxin products cover 1~32L FR-4 PCB, IMS PCB,HDI Boards, high frequency PTFE boards and Rigid-flex boards etc. We provides flexible quick turn production services (12hours to 72 hours), as well as small volume to big volume PCB manufacturing. And our products are widely applied to from communication industry, power supplies devices, computer networks to aerospace industry.
Layers:1-32layer, if the layer is 20L or mare than 20L, will need to review the board.
The max finish panel size is 740* 500 MM, but if panel side >600 MM, will need to review it.
The Minimum panel size is 5 * 5mm.
Raw materials of Printed circuit boards include FR4, Rogers,Halogen-free, High TG materials...
Blind and buried holes lamination press times: Press with same core ≤3times (>3 times needs to review)
PCB thickness capability is from 0.2~4.0mm, if thickness is less than 0.2 mm, or more than 4 mm, will need to review it at first.
PCB copper thickness capability: Inner layer≤ 6 OZ( but copper thickness ≥5 OZ for 4L,≥4OZ for 6L,≥3OZfor 8L and above shall be reviewed)
Outer layer copper: ≤ 10 OZ(≥5 OZ needs to review)
Bow and twist tolerance is 0.075%.
Min hole size: 1) If board thickness ≤2.0mm, min hole size 0.20mm. If Board thickness>2.0mm , min hole size: aspect ratio≤10(for drill bit)
2) If board thickness≤0.8mm, min hole size 0.10mm. If board thickness≤1.2mm, min hole size 0.15mm

FAQ:
Q1:What kind of PCB file format can you accept for production?
A: Gerber, PROTEL 99SE, PROTEL DXP, POWER PCB, CAM350, ODB+(.TGZ)
Q2. What any other information should be offered except for file?
A: Following specifications are needed for quotation:
1) Base material
2) Board thickness:
3) Copper thickness
4) Surface treatment:
5) color of solder mask and silkscreen
6) Quantity
Q3. No PCB file/GBR file, only have the PCB sample, can you produce it for me?
A: Yes, we could help you to clone the PCB. Just send the sample PCB to us, we could clone the PCB design and work out it.
Q4. What’s the BOM?
A: BOM is a Bill of Materials that list the components required to build your project. BOM’s include part number, brand, reference designator , quantity, and description of parts that need to be assembled.
Q5. Where are your circuit boards manufactured?
A: As a China-based professional PCB manufacturer, all circuit boards are manufactured in China.
