In our increasingly electrified world, batteries play a pivotal role in powering everything from electric vehicles to portable electronics. Sensofar’s Non-contact 3D optical systems are ideal for measuring surface texture, flatness, and critical dimensions of batteries, providing crucial insights for enhancing battery efficiency, lifespan, and safety.
Heat sink flatness
The flatness of the heat sink is a critical factor in the performance of a battery. As a passive cooling device that dissipates the heat generated by the battery modules, the warpage of the heat sink can significantly impact battery efficiency. In this scenario, it is Fringe Projection technology that can better assess it, providing fast and micron-level accuracy measurements.
Battery separator defect inspection
The primary safety element of a cell is the battery separator, which prevents direct contact between the two electrodes responsible for the flow of electrons during the operation of the battery. Optical areal measurements help to assess whether the irregularities on the surface of battery separators will or will not impact the overall performance and safety of the battery.
Coplanarity of BGA
Ball Grid Array (BGA) is an electronic packaging technology that utilizes solder balls to establish electrical connections between components and circuit boards. In the context of SiP batteries, it helps to save space.
The Bumps plugin automates the detection of bump-like structures and provides a range of parameters. Coplanarity is particularly crucial as it measures variations in bump heights. The height uniformity of BGA pins determines the connection reliability.
