KB:沉积铜盗取图案以实现均匀的镀层分布
Created: 十一月 11, 2024 | Updated: 七月 18, 2025
铜偷窃可能是制造商为了实现均匀的镀层分布,在最外层所需或所希望的。不幸的是,目前没有直接的命令/功能一次性实现铜偷窃,但已经找到了一个变通方法,即利用通过焊点特性来实现偷窃图案。
Solution Details
Unfortunately, there is no straightforward command/feature in one go to achieve copper thieving currently. There is a workaround identified to leverage Via Stitching feature to realize a thieving pattern.
1 Copy the poured polygon, which you want to thieve, to somewhere outside the board
2 Place another copper fill over, so you have something to stitch against
3 Apply via stitching to populate an array of vias within the polygon shape
4 Tools » Convert » Convert Selected Vias to Free Pads to covert the via array to free pads.
