一种纯FR-4材料半软板的制作技术

A technique for producing pure FR-4 material semi soft plate

文章主要针对纯刚性FR4半软板制作,刚性材料控深铣半软板的制作工艺技术,介绍了Mapping方法控制残余厚度控深铣,残余厚度公差±20?m以内。能够使同类型的坑槽产品保质保量快速完成,供同行业参考。

This paper introduces production technology of the pure rigid FR4 material semi soft board , rigid material control depth milling semi soft plate. It also introduces the mapping method to control milling depth, residual thickness control, with the residual thickness tolerance of ＆#177; 0.8mil. It is intended to make the same type of pit product quality and quantity quickly, and provides reference of the same industry.
