What is the best design for HDI hardware and soft board?
1. Tear shape is used between thick line and thin line to prevent sudden expansion or contraction of line;
2. Use rounded corners to avoid sharp angles.
3. Pad should be maximized
4. Design as many solid copper moorings as possible for the waste area.
5. Add manual alignment hole to improve alignment accuracy.
6. The design of the mouth considers the range of the flow of glue, usually the window is larger than the original design, the specific size is provided by ME design standards.
7. The smooth transition of the line, the direction of the line should be perpendicular to the direction of the bending;
8. Conductors should be evenly distributed throughout the bending area;
9. The wire width shall be maximized in the whole bending area, and the PTH design, Coverlay and No Flow PP design shall be avoided as far as possible in the transition area.
10. There can be no through hole in the part to be bent.
