foil profile

基本解释

So to produce the suitable low profile electronic copper foil for high density circuit board (HDI) is more difficult and pressing.
要生产出适合于高密度电路板（HDI）使用的低轮廓电子铜箔更加困难和紧迫。
On the above basis, the relationship between profile value and the flow control of cooling liquid in the foil rolling is determined.
在此基础上，确定板形值和冷却液流量控制的关系。
