[SI-LIST] Re: Need more insight on usage of a connector

Hi Chockalingam,

The mechanical stress will be more on the board as it is used in truck.=20
So it depends upon what mechanical support between the board and
dashboard, the placement of the connector and mechanical connectivity
between the two boards.

Obviously the through connector mechanical stability is more compared to
smd.

I have some questions to ask:

1. Do you have a proper mate between through hole and smd connector and
what is the pin count?
2. What is the reason for going one through hole and one smd? - Any
space or height constraint?

Regards,
Logu.K.S

Subject: [SI-LIST] Need more insight on usage of a connector

Hi all,
We are designing a unit that is planned to sit in the truck dashboard.

The system has 2 boards connected by a b2b connector.

My Qs...

1.      Is it advisable to use SMD connectors on one board and
through-hole
mating connector on the other?
2.      What are the pros and cons of using SMD connectors in such harsh
environments?
3.      Does a through-hole connector provide more mechanical stability
compared to the SMD variant?
