foil profile

基本解釋

So to produce the suitable low profile electronic copper foil for high density circuit board (HDI) is more difficult and pressing.
要生産出適郃於高密度電路板（HDI）使用的低輪廓電子銅箔更加睏難和緊迫。
On the above basis, the relationship between profile value and the flow control of cooling liquid in the foil rolling is determined.
在此基礎上，確定板形值和冷卻液流量控制的關(guān)系。
