Product Description

Looking for 4 oz Heavy Copper PCB Manufacturer, Find high quality 4 oz Heavy Copper PCB Manufacturing and low cost support at JHYPCB

Heavy Copper PCB or Extreme Copper PCBs have special requirements. We can help you verify your design and provide Prototype through Assembly services.

4 Oz Copper PCB Is a heavy copper PCB, Only 2 layer , still many PCB manufacturer can handle it, if multilayer PCBs, inner layer is 4 oz, few PCB factory can fabricate it well. JHYPCB have rich experience manufacturing 4 oz PCB whatever double side or Multi-layer PCB.

4 OZ heavy copper printed circuit PCB. Heavy Copper Board does not have a set of definition in IPC standard. However, peopel generally use this name to identify a Printed Circuit Board with copper conductors 3 oz/square feet- 10 oz/square feet in inner and/or outer layers.

General Guideline for Min Spacing by Copper Weight

Cu Weight: Min Recommended Space between Copper Feature

4 OZ: 14 mil (0.355 mm)

Heavy Copper PCB Range of Options

Heavy copper printed circuit board manufacturing includes both single, double-sided, and Multilayer PCB. The single and double sided are the most basic high-current printed circuit board configurations available for practical use. Simple configurations keep production costs low, but it may present a challenge in terms of board construction.

As layers are added, PCBs become more complex. They can be used to relay hefty current loads and handle multiple functions. Thick copper plates work well in specific industries where higher performance and processes are required.

You May Ask:

What is the thickness of 1 oz of copper on a PCB?

PCB Copper Thickness. The copper in a PCB is rated in ounces, and represents the thickness of 1 ounce of copper rolled out to an area of 1 square foot. For example a PCB that uses 1 oz. copper has a thickness of 1.4mils.

What is the standard thickness of a copper layer on a PCB?

1 oz copper (~35µm thick or 1.4 mils) - Standard internal layer copper thickness for "standard construction product for 1 oz and 2 oz finished copper weight selections. This is also the standard starting copper weight on the external layers for PCBs with the 2 oz finished copper weight selection.

How thick is a PCB?

We process four layer PCB boards with final thickness of 0.020", 0.031", 0.040", 0.047", 0.062", 0.093" and 0.125". You may select ½, 1 or 2 ounce inner layer copper foil for your board. While our 4 and 6 layer boards are limited to 16X22 inches the 8 layer is 12x18 and 10 layer maximum size is 10x16.

PCB Shipment

JHY PCB offers flexible shipping methods for our customers, you may choose from one of the methods below.


Shipping Process
After production and testing, your PCB orders will be sent to our shipping department. As the quick turn PCB manufacturer, JHY PCB shipping department will ship your PCB quickly without any pending.

JHY PCB 's Packing Way

  • Use one professional PCB vacuum bag, with desiccant inside. Vacuum compressed totally.
  • Paste label and RoHs mark. Use second vacuum bag to protect boards again, vacuum compressed, make sure no exception.
  • Microsection report and Tin testing board are put together with PCB in cartons.COC (Certificate of Conformity) will be sent to customer by email in PDF.
  • Several layers of thick EPE(Expand aple poly ephylene) are filled fully in gaps between PCBs and cartons. Thickness of 1 layer EPE is 10mm.
  • Neutral Packing is adopted if no special requirements. Strong and thick cartons(Thickness:10mm,7 layers). Different sizes of cartons are designed to meet demand of different PCB size. All package are within weight limit of cartons. For mass production order, no exceed 21kg per carton normally.
  • All cartons sealed with strong adhesive tape should be sealed twice so as to make them more durable.
  • Solid PP/PET strapping is used outside of cartons.
  • Shipping mark, fragile mark and postcode label are all pasted clearly.
Whatever we do or whatever we think of is to make sure boards are shipped to customer safely and quickly.
