PCBニュース - PCB設計プロジェクトチェックリスト

（1）回路図の合理性及び正しさの確認

回路図のコンポーネントパッケージの正しさを確認します

3. 強い電流と弱い電流の間の距離, the distance between isolated areas;

4. 回路図をチェック PCBダイアグラム correspondingly to prevent the loss of the network table;

5. Whether the package of the component is consistent with the actual product;

6. Whether the placement of the components is appropriate:

A. Whether the components are easy to install and remove;

B. Whether the temperature-sensitive element is too close to the heating element;

C. Whether the distance and direction of the components that can generate mutual inductance are appropriate;

D. Whether the placement between the connectors is smooth;

E. Easy to plug and unplug;

F. Input and output;

G. Strong current and weak current;

H. Whether digital and analog are interlaced;

I. Arrangement of elements on the upwind side and downwind side;

7. Whether the directional component has been wrongly flipped instead of rotated;

8. Whether the mounting holes of the component pins are suitable and whether it is easy to insert;

9. Check whether the empty pin of each component is normal and whether it is a missing wire;

10. 同じネットテーブルの上下の層にバイアホールがあるかどうかをチェックする, and the pads are connected through the holes to prevent disconnection and ensure the integrity of the circuit;

11. 上と下の文字が正しく、適切に配置されているかどうかを確認する. 文字を隠すために部品を置くな, so as to facilitate the operation of welding or maintenance personnel;

12. 上下の層の非常に重要な接続は、インライン構成要素のパッドと接続されてはならない, it is best to use vias;

13. The arrangement of power and signal wires in the socket should ensure signal integrity and anti-interference;

14. Pay attention to the proper ratio of pad and solder hole;

15. プラグは、の端に配置する必要があります PCBボード as much as possible and easy to operate;

16. コンポーネントラベルがコンポーネントに一致するかどうかを確認する, and the components should be placed in the same direction as possible and placed neatly;

17. 設計ルールに違反しない場合, the power and ground wires should be as thick as possible;

18. 平常に, 上層は水平で下層は垂直でなければならない, and the chamfer shall not be less than 90 degrees;

19. PCB上の取付穴のサイズと分布が適切かどうか, and minimize the PCB bending stress;

20. Pay attention to the height distribution of the components on the PCB and the shape and size of the PCB to ensure easy assembly;

The above is the introduction of the PCB設計 プロジェクトチェックリスト. IPCBは、PCBメーカーとPCB製造技術も提供します.
