Smart Card

2 layer Flex with 0.4 mm BGA and VIP. Ormet Paste for via fill.

This smart card application has a .4 mm BGA pattern on a double sided flex so it has to be via in pad (VIP). VIP requires sanding and planarization if you are doing any kind of plating. These processes stretched the flex material. To combat this we used ormet paste but we are now working more with Tatsuta paste for the same application.

Smart Patch

2 layer Flex with ICT hinge design for flexibility and conformance to any topography. Low stress on solder joint.
