So? Do you have any solution to overcome the carbonized residue on the edge problem ?? From: TGAsia [mailto:[log in to unmask]] On Behalf Of Joseph Ho Sent: 19 June 2008 13:58 To: [log in to unmask] Subject: Re: [TGA] 有关激光分板的可靠性问题 Dear all, Use laser to cut the outline is possible and can be applied in Flexible PCB in sample build, our FPCB is thickness and no fiber glass. However, for rigid PCB, the board thickness is the great concern as the resin and fiber glass need large energy to cut. Besides, burn the outline may have carbonized residue on the edge.

From: TGAsia [mailto:[log in to unmask]] On Behalf Of Renie Zhao Sent: 18 June 2008 15:18 To: [log in to unmask] Subject: [TGA] 有关激光分板的可靠性问题 Dear All: 为了提高PCBA 的分板效率,我们试图用激光切割机进行分板,但是在分板过程中总是 有碳化现象, 我们也进行了可靠性测试(功能,跌落,温湿循环,热冲击, 功能), 发现即使有轻微碳化现象,也不影响PCBA 的性能。有关此事请教大家下面几个问题: 1. 在IPC 的标准中,用激光进行PCBA的分割,是否允许有轻微碳化现象? 2. 如果不允许,在我们进行了一系列的可靠性 测试之后,如果确认轻微碳化 并不影响其性能,那么有没有可能根据实际更改一下IPC 的标准?
