4L Multilayer Printed Circuit Board Heavy copper impedance control immersion gold 30um hole copper
4L Printed Circuit Board with 30um Hole copper
Shenzhen Huashengxin Circuit was founded in 2010. It is a professional PCB manufacturer. Its products cover from single layer to 32 layer FR4 PCB, IMS PCB, HDI Boards, Copper base PCB, high frequency PTFE boards and Rigid-flex boards, etc. and they are widely applied to from communication industry, power supplies devices, computer networks to aerospace industry. HSX provides flexible quick turn production services (fastest 12hours to 72 hours), and also small volume to big volume PCB productions.
Layer: 1-32layer( will need to evaluate the board its layer>/=20L).
The max finish panel size is 740* 500mm, but if panel side >600 MM, will need to evaluate it.
The minimum panel size is 5 * 5mm.
Raw materials: FR4, Rogers,Halogen-free, High TG materials, Copper base, Al base, etc
PCB thickness: 0.2~4.0mm(will need to evaluate it at first if thickness is less than 0.2 mm, or more than 4 mm)
PCB copper thickness: Inner layer≤ 6 OZ( but copper thickness ≥5 OZ for 4L,≥4OZ for 6L,≥3OZfor 8L and above shall be evaluated)
Outer layer copper: ≤ 10 OZ(≥5 OZ needs to be evaluated)
Bow and twist tolerance: 0.075%.
Min hole size: 1) If board thickness ≤2.0mm, min hole size is 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 is 0.10mm. If board thickness≤1.2mm, min hole size is 0.15mm
Solder mask color: Green, matt green,blue, matt blue, black, matt black, yellow, red, white, and as customers specify.
Silkscreen color: White, black and as customers specify.
Surface finished: HASL, LF-HASL, ENIG, Immersion Sn, OSP, Selective ENIG + OSP, Immersion Silver, ENEPIG, Plating hard gold,etc.

FAQ:
Q1:Are you a factory or trade company?
A: We are and PCB factory in Shenzhen, China. We have independent quick turn prototype PCB manufacturing line and mass 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 3rd parties. 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. But we need you to send us the sample PCB, we could clone the PCB design.
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)
4-8 Layers: 7~12 working days (fastest 48hours for quick turn)
Mass production (less than 200sqm):
1-2 Layers:7 to 12 working days
4-8 Layers:10 to 15 working days
Q6:What payment terms do you accept ?
A: Wire Transfer(T/T), Letter of Credit(L/C), Paypal(only for small value less than 500usd)
