可以的,但是via孔徑是8mil左右的,不能太大,謝謝! 寄件者: TGAsia [mailto:[log in to unmask]] 代理 QA 寄件日期: 2014年3月6日 下午 08:42 收件者: [log in to unmask] 主旨: [TGAsia] 有关PCBA涂绝缘油通孔的规定 各位: 现我们公司有对PCBA进行涂绝缘油(Conformal Coating - Silicone Resin)。但发现有一个问题,当绝缘油加在PCBA上后,它的油会从过孔(不用焊元件的通孔)穿过流到对面PCB板上,我们的PCBA背面有元件不能粘到油。我查得610E里只有对厚度的要求。 有人说要想油不从过孔流到反面,需要将那个过孔给堵住,请问各位,是否要这样做,如果要这样做是否有标准提到了这个要求。 曾经在IPC的邮件里面,有讨论过 Conformal Coating 是否要洗板,但没有讨论过孔漏油的问题。 Best wishes for you ====================== He Yun QA Dept. ====================== Manson Engineering Ind.
