HDI由于其高密度线路排布，使得其拥有轻量化、高电气性能、高可靠性等优势，

被广泛应用于消费电子、通讯设备等领域；

而由于其孔数多而密集的特性，使得钻孔过程中，极易发生由于一侧孔壁较薄而导致的孔偏、

偏孔断刀等问题;而是高端存储板，由于其粘性的数值使得其在HDI的基础上又多了孔粗难以控制的钻孔难点。

Due to its high-density circuit arrangement, HDI has advantages such as lightweight,

high electrical performance and high reliability.

It is widely applied in fields such as consumer electronics and communication equipment;

Duetoitslarge and dense number of holes, during the drilling process,it is very easy for hole deviation to occur 

because one side of the hole wall is thinner.

Problems such as off-center holes and broken knives; Instead,it is a high-end storage board.

Due to its sticky value,it has the additional difficulty of controlling the hole diameter on the basis of HDl.
