 |
- Better test yield
- Larger contact surface area
- Lower contact force
- Minimal chance of damage to DUT contact (e.g., solder ball)
- Higher pin count
- Can accommodate smaller pitch devices
- Cost effective
- Less Maintenance
- Negligible Maintenance compared to pogo pin
- Industry trend
- Major customers accepting rubber sockets
- Total Cost Advantage

 |
 |
 |
- - Much better, non-damaging contact with solder balls on DUT
- - No sharp contact tips: No dent or damage to DUT solder balls
- - Much lower required contact force
- - Much more consistent, predictable test yield
|
 |
- - SRC is currently capable of producing 0.30mm pitch rubber sockets
and interposers
- - Can accommodate more package configurations
- - Can offer cost advantage with higher pin-count devices
|
 |
- - No cleaning or replacement by a skilled technician using a microscope
is necessary
- - SRC rubber sockets require only periodic simple, quick cleaning
- - No need to go through a difficult re-assembly process
- - No need for cleaning solvent, steel brush or supply of particle-free
air -- or worse, laser cleaning equipment
- - No danger of cleaning process causing damage to plating or resulting
in corrosion that can reduce test yield
- - SRC rubber sockets are cleaned at once with an adhesive tape to
remove any particles or debris
|
 |
- - For devices suited for rubber sockets and rubber interposers, major
customers are starting to accept the advantages of rubber socket and
some have already started putting them in use
- - They are expanding the usage of rubber sockets and interposers
across product lines for:
* Cost advantage
* Significantly easier and quicker maintenance
* More flexibility with finer pitch capability
