Quick Turn PCB Boards Fast PCB Prototyping Service ROHS Compliant PCB Fast PCB Fabrication
4L Fast Turn FR4 Printed Circuit Board
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

Q1:Are you a factory or trade company?
A: Yes, we are the factory, we have independent quick turn prototype PCB manufacturing & big volume PCB production lines.
Q2:What kind of PCB file format can you accept for production?
A: Gerber, PROTEL 99SE, PROTEL DXP, POWER PCB, CAM350, ODB+(.TGZ)
Q3:Are my PCB files safe when I submit them to you for manufacturing?
A: We respect customer's copyright and will never manufacture PCB for someone else with your files unless we receive written permission from your side, nor we'll share these files with any other 3rd parties. And we could sign NDA with client if necessary.
Q4:If we have no PCB file/Gerber 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.
Q5:What is your standard lead time for PCB?
A: Sample/prototype(less than 3sqm):
1-2 Layers: 3 to 5working days (fastest 24hours for quick turn services)
4-8 Layers: 7~12 working days (fastest 48hours for quick turn services)
Mass production (less than 200sqm):
1-2 Layers:7 to 12 working days
4-8 Layers:10 to 15 working days
Q6:What payment do you accept ?
A: Wire Transfer(T/T) or Letter of Credit(L/C) or Paypal(only for small value less than 500usd)
