PTPR & CVPD Test Profile
   
Definitions:
Pin-to-Pin Resistance and Clampdown Voltage of Protective Diode testing, or PTPR/CVPD, is a preferred testing option for high pin count and complex
components where set-up for functional testing can be prohibitively long and expensive.
 
* Fast Set-up & Programming Time
* Fast Test Cycle Time
* Low Price
* High Degree of Reliability
  
Complete Testing Profile includes:
* Pin-to-Pin Resistance Test
* Clamp-down Voltage of Protective Diodes
* Decapsulation Analysis (recommended)
* Golden Sample Comparison(recommended) 
The #1 Cause of Component Failure is Opens and Shorts Caused by Overvoltage and Damaged Hardware. PTPR/CVPD Catches It. 
 
   
Clampdown Voltage Protection Diode (CVPD) testing includes:
* Continuity (Pin Opens & Shorts)
* Damaged Protection Diodes
* Misalignment & Disoriented Dice/Lead  Frame
* Internal circuitry damage
  
Pin-to-Pin Resistance (PTPR) testing:
* Adjacent pin shorts
* Opens between ground pins
* Resistance between two pins will be measured
* Identifies the #1 Cause of Component Failure
 
Notes: PTPR/CVPD test is the step between simple curve trace and functional or parametric testing on complex devices where set-up time and cost may be prohibitive. And this test covered all of the pins whereas CT targets only a limited number of pins.

Attention: Week 6 report will be sent on 2016/2/16, and there will be no report sent for Week 7, as there are no testings and deliveries in CNY Holidays, thank you!
 
 
We hope you find this report informative and usefull for your organization. 
  
All the best,
