Flip Chip Assembly

When you’re ready for Flip Chip, Aspen Technologies can provide you with successful implementation & rapid time to market. Aspen can assist in choosing the perfect bump technology and materials to meet your requirements, execute the substrate design, produce prototypes, manage the qualification, and manufacture your devices in its Colorado facilities (or at an off-shore partner if in sufficient volume). Flip Chip has entered the advanced packaging mainstream, and devices like microprocessors, DSPs, driver chips, smart cards, and even MEMS are taking advantage of its strengths:

  • Smaller footprint
  • Greater interconnect density
  • Faster speeds (lower resistance, capacitance, & inductance)
  • Excellent thermal management

Introduced in 1964 by IBM as the C4 process (Controlled Collapse Chip Connection), Flip Chip now offers a viable & proven alternative to standard assembly technologies for products requiring enhanced performance. Aspen Technologies has extensive experience with a wide range of Flip Chip bump & assembly methodologies, and mating them with diverse substrates: organic, ceramic, HiTCE, flex, Si on Si, and others.


Whether your device requires three bumps or 3,000, has single or multiple die, requires lead-free, eutectic, or Stud Bumps, Aspen can provide a full assembly solution for you as it has many other recognizable industry names for nearly 10 years!
