Nu Signal was founded to address the problem of accelerated socket failures occurring in the Semi industry (primarily due to increased BGA device usage). Nu Signal works with many of the largest Semiconductor manufacturers throughout the world, and has presented technical papers on the subject with colleagues in the industry. Test & Burn-In Socket Restoration: n Nu Signal provides socket restoration services for the semiconductor manufacturing industry allowing companies to reuse failed sockets instead of purchasing replacements. n Nu Signal's technology restores failed sockets through an exclusive decontamination process. Customers avoid costly replacements by restoring test sockets, burn-in sockets, spring probes, heat sinks, and programming modules. n Test Socket Cleaning (Contact Restoration): Completely restore yield to test sockets, memory sockets, and probes. Renew life to exceed OEM performance levels. Applications: |
| | Nu Signal’s Socket Cleaning Technology Restores: Burn-In Boards (Entire Board - Without Removing Sockets) Test Sockets Test Probes (Spring Pins/Pogos, Test Inserts, etc.) Programming Sockets, Modules and Adapters HAST Sockets PCB Pads (Restore DUT Pads)
|
BURN-IN  | Entire Burn-In Boards can be processed to restore socket contacts, or the sockets can be processed individually. |
TEST | | Test contactors and sockets often lose electrical functionality long before the connector system has reached its mechanical limit. Test signals can be returned to new performance levels with Nu Signal’s advanced restoration process.
The process is not limited to coarse pitch products. Sub 0.50mm pitch arrays are easily processed. Costly Pogo Pins can be reconditioned, instead of replaced. |
Time Lapse

LOGIC/PROGRAMMING (PLD, MEMORY)
| Sockets, Modules and Adapters used in programming fail primarily as a result of solder contamination. Contact surfaces become oxidized, resulting in high reject rates. The Nu Signal process returns Yield to 100%. |
HAST (Highly Accelerated Temperature/Humidity Stress Test)
| Sockets are severely contaminated during HAST. Sockets can be restored for significantly less than replacement cost. Restoration also applies to Temperature Humidity Bias (THB).  
|
PCB PADS
| Spring Probes damage PCB Pads. Restored Pads reduce contact resistance:   |
