整理了一些軟板(FPCB/Flex Cable)製造廠關於線路設計的要求 (Design Guide)以避免應用上的品質問題。
| 1.Relationship between Through Hole, Land, Cover Film, and Cover Coat |
| Not Recommended(不建議) | Recommended(建議) | |
 |
 |
|
 |
 |
|
| 通孔的焊墊必須用Cover film 覆蓋住，以避免使用時剝落。 |
 |
|
| 2. | Circuit Pattern Guidance | |
| Not Recommended(不建議) | Recommended(建議) | |
| Avoid sudden expansion or reduction in pattern width. No sharp angle. | 避免在線路的寬度上突然的變大或是變小，而起不應該有尖角出現。 | |
 |
 |
|
 |
 |
|
| 3. | Design at Folding Area | |
| Not Recommended(不建議) | Recommended(建議) | |
| If the FPC need to be folded then the folding area shall be covered with cover film to prevent trace breaking. | 如果軟板有彎折的需要時，建議Cover Film必須覆蓋過彎折處，以避免線路折斷。 | |
 |
 |
|
| Avoid folding at below locations a. The change of pattern width. b. Folding parallel to the pattern. |
避免以下的彎折及方法： a.線路寬度改變的地方。 b.平行線路彎折。 |
|
 |
 |
|
| 4. | Plating Leads | |
| Not Recommended(不建議) | Recommended(建議) | |
| Plating leads and disconnection holes should be designed as illustrated in order to avoid short circuits. | 相鄰線路應該盡可能用最大角度展開以避免短路。 | |
 |
 |
|
| 5. | Connector Terminal | |
