Challenges Grow For Creating Smaller Bumps For Flip Chips

New bump structures are being developed to enable higher interconnect densities in flip-chip packaging, but they are complex, expensive, and increasingly difficult to manufacture. Jeff Schaefer, senior process engineer at Promex Industries, shared insights into this...

3D Structures Challenge Wire Bond Inspection

Adding more layers in packages is making it difficult, and sometimes impossible, to inspect wire bonds that are deep within the different layers. Jeff Schaefer, senior process engineer of Promex Industries, shared insights into this challenge in this Semiconductor...
