IPC 4562 Copper Foil

The IPC 4562 standard applies to metal foils supported or unsupported by carrier films for printed circuit boards. The IPC 4562 standard is a world authoritative standard that comprehensively regulates the variety, grade, and performance of copper foil. It is progressiveness in the world and replaces the IPC-MF-50G standard implemented by most of the original copper foil manufacturers in the world. IPC-4562 specifies the types and codes of metal foil: E-electrolytic copper foil, W-rolled copper foil. Electrolytic copper foil refers to copper foil made by electrodeposition, while rolled copper foil refers to copper foil made by rolling method, also known as forged copper foil.IPC 4562 Copper Foil is widely used in market

 

 

 

We provide the 1/3oz/ft2 to 3oz/ ft2 (nominal thickness 12 µ m to 105 µ m ) high temperature elongation (THE) ED copper foils,the widths are from 250-1340 mm,and the quality reaches the II and III requirements of the international standard IPC-4562,these products have the perfect normal temperature storage performance,the high temperature anti-oxidization performance,and high temperature elongation performance,and can be used in the production of the different double-face and multi-layer printed boards.We can also provide low-profile(LV)and very low-profile (VIP) THE ED copper foils.

Copper Foil Produced via electrodeposition from a copper sulfate solution onto a rotating titanium or stainless steel drum.The deposited copper is peeled off, then treated (roughening, heat resistance, anti-corrosion).

Rolled Copper Foil Made by cold-rolling high-purity copper cathodes into thin sheets, followed by annealing.Surface can be further treated (e.g., oxidation resistance coating).

 

PRODUCTION PROCESS FLOW CHART

 

 

Common Language and Quality Consistency: IPC-4562 provides a unified "language" for copper foil producers and PCB manufacturers worldwide. When a manufacturer specifies a need for, say, an "IPC-4562 Class 3 HTE foil," they can ensure that materials sourced from any compliant supplier will have consistent and predictable performance (e.g., tensile strength, elongation). This significantly reduces the risks associated with fluctuations in incoming material quality.

Simplified Procurement and Quality Inspection: The standard defines clear test methods and acceptance criteria, leading to unambiguous procurement specifications and providing a solid foundation for Incoming Quality Control (IQC). This streamlines supply chain management and improves production efficiency.

Enhanced Process Stability: The guaranteed key parameters of compliant foils (such as the high-temperature elongation of HTE types) ensure that PCBs are less susceptible to cracking or fracturing during the high-temperature and high-pressure lamination process for multilayer boards. This directly increases the yield of the lamination process and the reliability of the final product.

Q1: What info. should I let you know if i would like to get a quotation for the the Electrolytic copper foil?

A1: The material size (Thickness*Width*Length and total Qty). If possible, it would be more better to advise the application of the product

Then we can recommend the most suitable products with details for confirmation.

 

Q2:How long is your delivery time?

A2:Generally it is 5-10 days base on we have stock on hand. or 15-20 days if no inventory, then need check with our production team for lead time according to the quantity.

 

Q3: Do you provide samples ?

A3:Yes, if standard sizes sample is free but buyer need to pay freight cost.

 

Q4:What is your terms of payment ?

A4: Normal payment term is 30%TT, 70% before shipment get ready to ship

 

Q5: How do you guarantee the quality of the products?

A5: Each step of production and finished products will be carried out inspection by QC department before storing to the warehouse. NG products are not allowed in the completed goods warehouse.
