Hirose Connector mating

Postby JRenfrew » Mon Dec 12, 2016 4:43 pm

We've been having difficulty obtaining 100% pin mating on the DART-MX6 boards, even on brand new product.

Under microscope we've been finding a lot of dirt in the Hirose connectors on brand new factory sealed boards and in the trays they ship in. Primarily we find fiberglass shards from the board edges but we also find fibers and other material trapped in the connectors too. We feel this is causing the majority of our connector mating issues. About 14% of our loads are failing because of connector related issues. Using compressed air to clean the connectors before insertion has reduced the failure rate but not eliminated it.

We've documented, with photographs, the dirty connectors and trays that the Dart ships in.

In our earlier shipments of Dart boards we seemed to find white flecks of material left over in the Custom Board connectors after mating new boards into it. We're unsure where those came from, but they were causing loading issues too.

Is it possible for Variscite to control the packaging of the boards better to prevent dirt entering the packaging?
Is it possible to prepare the card edges better to prevent fiberglass shards from being released?
We're also wondering if there is a ZIF socket available for this board?

Can you please log in to our support portal at https://varisciteportal.axosoft.com/
and fill-out a support ticket on this issue and attach any documentation/pictures you have on this issue.
We would like to further investigate this since we much effort in keeping a sterile environment in our production facility and are not
familiar with such issues.
The current SOM connectors are the only option for this SOM.
