twist and camber
(OP)
New at a job designing HDMI connectors. Still learning a bunch, appreciate it if anyone would care to explain a few terms on an engineering drawing I'm looking at:
Finish:
Ni UNDER PL
GOLD PL
TIN (MATTE)
[Matte is the question I have. Is it referring to it being the top layer of plating?]
Camber: 10 MAX/1000
Twist: 20° MAX/1000
FLEXED THE SIDE CUT FORM BY DIE DESIGN
It's a Japanese Engineering drawing
Thanks much
Casey

RE: twist and camber
Gold plating over the nickle.
The tin is put on as a non-shiny rough layer good for soldering. I don't know what part you have there but rarely is tin put over gold. I suspect the tin is on the other end of the pins for soldering.
The tin matte is the replacement for the superior but non-RoHS tin-lead plating.
Camber is the maximum bent-angle seen in 1000 units.
Same idea with the twist.
