Semiconducer IC Technology Trend

Semiconductor IC Technology evolution ; BGA, LGA

PCR socket
  1. Increased lead count
  2. Lead pitch shrink(>0.8p→0.5p→0.4p→<0.3p)
  3. Increased signal transmission speed
  4. Decrease signal voltage level(3→1.5→1→0.6→<0.5V)
  5. Package thickness reduction (<1mm)
  6. 2.5D/3D Package (MCP, SIP, POP, PIP, etc)

Contact Resistance vs Cost to Test

  • Primary test yield difference due to performance difference between semiconductor test sockets

    PCR socket

  • COT difference due to the difference in life span between semiconductor test sockets

    PCR socket

  • Factors increasing CoT

    1. Increased Retest Costs
    2. Decrease equipment efficiency
    3. Increased Socket(Pin) Replace Costs
    4. Increased Equipment downtime
    5. Reduced Socket Cycles
