+## ⚙️ Key Factors
7
+
8
+The current-carrying capacity of a 2.54mm (0.1 inch) wide PCB trace depends on:
9
+
10
+- **Copper thickness** (measured in oz/ft²)
11
+- **Temperature rise allowed**
12
+- **Trace location** (internal vs. external)
13
+
14
+---
15
+
16
+## 📊 General Guidelines (Based on IPC-2221)
17
+
18
+| Copper Thickness | Trace Type | Temp Rise | Approx. Max Current |
19
+|------------------|----------------|-----------|----------------------|
20
+| 1 oz (35µm) | External trace | 10°C | ~2.6 A |
21
+| 1 oz (35µm) | External trace | 20°C | ~3.8 A |
22
+| 2 oz (70µm) | External trace | 20°C | ~5.0–6.0 A |
23
+| 1 oz (35µm) | Internal trace | 20°C | ~2.0–2.5 A |
24
+
25
+> 📏 Rule of thumb: For **1 oz copper**, every **1mm width** can safely carry **~1 A** (for external traces and ~10–20°C temp rise).
26
+
27
+---
28
+
29
+## 🧠 Tips
30
+
31
+- Use **wider traces or thicker copper** if higher current is needed.
32
+- Consider **thermal relief**, **via stitching**, or **multiple layers** for better performance.
33
+- For high currents (>5 A), use **solid copper pours** or **bus bars**.
34
+
35
+---
36
+
37
+## 🛠️ Example
38
+
39
+For a **2.54mm wide**, **1 oz copper** external trace with **20°C rise**:
40
+- Safe current = ~3.5–4.0 A
