[Dsg-hallc_controls] [EXTERNAL] CAEN Connector Pin Question

Mon Feb 17 12:12:24 EST 2020

Hello Aaron,
thank you very much for the details.
Really strange a so high number of problems on the panel connector, as 
told from our experience it is more problematic the cable connector, 
this is the reason that we add the hot glue.
At this point let me know how you wish proceed.
To rework/repair the boards with pins pushed out we have two solutions, 
you ship the boards to our office in NY, or I could make an intervention 
in JLAB in spring.
How many boards you have in total?
May be it's worth to have a look to al the boards.

Waiting your comments.
Best regards.
Gianni
