Procedures in comparison

A good question and a new aspect would be to find out which kind of importance the ratio of specialized skills, benefits and differentiations influence the procedure decision finally. But who is able to give a reliable answer?

It is an objective fact that semiconductor manufacturers and PCB manufacturers have opposite interests, and their efforts to reach a continuous and profitable collaboration are not always recompensed. Hence the purchase quantity and the volume of the annual turnover may play a significant role to start an adequate discussion.

There are different approaches to integrate well-tried technologies and new consistent strategies in the Re-Design process. However what about its feasibility in such an innovative and fast moving segment?

Finally, technology, competence and availability will determine the choice of the procedure whereas efficiency and quality will definitely remain the basic conditions.

ProcedureCertaintyUncertainty
Long-Term Storage
Completed PCBs
  • verified functionality
  • fast availability
  • arguable efficiency
  • partially unprotected storage
  • uncertain product life time
Semiconductors
  • economically advantageous
  • real product life time is maintained
  • technologically inadequate
  • low interest of semiconductor industry
  • scepticism of the PCB manufacturers
  • limited technological expertise in warehousing at present
Wavers/Dies
  • economically advantageous
  • real product life time is maintained
  • low interest of semiconductor industry
  • uncertain quality due to uncontinuous processes of the semiconductor manufacturers
  • limited technological expertise in warehousing
Disassembly
Through-hole devices SMD-technology
  • environmental friendly
critical:
  • efficiency
  • processing/product quality
  • safeguarding product procurement
  • product life time
  • SMD-devices: Technologically not protected
Re-Design
Re-Development or New development
  • medium-term supply is provided
  • optional product optimization
critical:
  • resource commitment
  • deadlines
  • development equipment
  • verification and validation complexity and profitability
  • several Re-Designs are necessary in life time
