When ordering or specifying copper foil, engineering documents utilize the IPC-4562 line callout system. A typical specification string includes codes for foil type, thickness, profile, and surface treatment.
: Used for procuring foils that will eventually become the conductive layers of rigid, flexible, and rigid-flex PCBs. 2. The IPC-4562 Designation System
The IPC-4562 PDF details acceptable ranges for critical performance metrics: ipc-4562 pdf
Created by electroplating copper onto a rotating titanium drum. It features a smooth "drum side" and a rough "matte side" ideal for bonding to laminates. It is the most common foil type for rigid PCBs.
IPC-4562A is a foundational document for anyone involved in the design, fabrication, or procurement of printed circuit boards. By adhering to the standards outlined in the IPC-4562 PDF, manufacturers can ensure high-quality, reliable PCB performance, particularly in challenging environments or high-speed applications.
| | Process | Key Characteristics | Typical Applications | |----------|-------------|------------------------|--------------------------| | Electrodeposited (ED) | Copper is electroplated onto a rotating drum and then peeled off | Lower cost, higher hardness, higher surface roughness | Rigid PCBs, consumer electronics, general-purpose boards | | Wrought (RA - Rolled Annealed) | Copper ingots are mechanically rolled to the desired thickness | Superior ductility, smoother surface, better fatigue resistance | Flexible circuits, dynamic flex applications, high-frequency designs | (Base Material Specification) to ensure a consistent global
Hi everyone,
To ensure you are using the most current and accurate data, always obtain the standard directly from the IPC (Association Connecting Electronics Industries) official website. Using official copies ensures you are compliant with the latest revisions and amendments.
The standard defines grades based on purity and performance characteristics, and classes based on the level of quality assurance applied: A typical specification string includes codes for foil
For procurement teams, simply asking for "FR-4" is no longer sufficient. The IPC-4562 standard allows you to specify materials by their exact designation, ensuring you get the thermal performance (Tg) and CTE (Coefficient of Thermal Expansion) required for lead-free soldering processes.
The standard defines classes based on the mechanical properties and surface roughness of the foil:
