PIC10F devices dies

I'm facing an issue with PIC10f200 devices.
 
During production, about 5% of those devices die. 
 
I've been working many years with dspic33, pic24 and pic32 and never had such issues.
 
Is the 10F family more sensitive to ESD or soldering temperature profile than the other?
 
Should the programming connector have ESD protection? (programmed with pickit3 and 4).
 
The pic is powered at 3.3V.
 
Thanks

    During production or during programming for production?

    I used this chip on my last design, programmed 1,000's with no issues.

    I'd have to check the datasheet but this chip was really basic and probably didn't have ESD diodes on the pins.

    10f200 certainly has ESD diodes.
     
    PK4 has been known to damage old devices with 12V programming. The "fix" is apparently to add a 100ohm resistor in the MCLR line from the PK4. I don't use PK4 or old devices, so no personal experience.

    And the ICD4 also has the same "feature".

    Great... Thanks for the feedback.
     
    I managed to replace the PIC functionality using discrete circuitery.
