FULLY UNIVERSAL DESIGN
This is the most common universal approach. In this approach every ROW of sockets would have a connector where a program card with a dedicated circuit would be assembled.
- One universal board per package type.
- This works best if the socket cost is high
- Complete flexibility on the wiring per circuit, since the component would be on the program card.
- A design for a universal card is possible. This would mean one design charge and a fabrication of many cards that can be assembled per circuit as the need arise.
- Density is less than that of the dedicated circuit
- The cost for the motherboard is higher since there has to be a cost factor for the connector that will house the various program cards used.
- For every circuit a program card has to be wired. So in essence you still need to pay for the cost of components per circuit.
- Instead of having on PC board, here you would need a Mother board and a Program card for every 4 positions. So for 100 position you would need 25 program cards. So every circuit would have a program card that is used to make the Mother board dedicated for that circuit at the time of use.
