At yellow color ribs suggest at 0.25 degree draft angle.
EM: 25/01/2017
Waiting updated the CAD file for improve ejection part issue.

8. And suggest add recess for gate. Dia 6 x 0.6mm
Gate point suggestion
Radius Comment ( ):
What’s the down side if flow front temperature more than 10 degree?
Hot tip Direct gate
Radius Comment ( ):
Please refer to updated 3D sent on
Excel comment –
Temperature more than 10degree different, it may have some difficult for flowing on the thin position.
And suggest add recess for gate. Dia 6 x 0.6mm
EM: 25/01/2017
Waiting updated the CAD file for gate recess.

13. PRELIMINARY COOLING LAYOUT
Move side
Fix side
Two layers

14. MOLDFLOW ANALYZE：
Material：PC Makolon 2407

15. MOLDFLOW ANALYZE：Fill time
Bad welding
Radius Comment ( ):
OK as the weld lines are not visible and not significant to part strength.

16. MOLDFLOW ANALYZE：Fill time

17. MOLDFLOW ANALYZE：Air traps

18. MOLDFLOW ANALYZE：Temperature at flow front
The temperature dropped rapidly
Radius Comment ( ):
Let’s keep the current geometry and if short shot happened, may increase ribs wall thickness to improve the ease of flow while having slightly sink mark at non-visible area.
Radius Comment ( ):
What’s the down side if flow front temperature more than 10 degree?
Excel comment –
Temperature more than 10degree different, it may have some difficult for flowing on the thin position.
Temperature at flow front between to degree,
Temperature different large than 10 degree, a little bit big different.
Remark：Melt temperature-300 degree.

19. MOLDFLOW ANALYZE：Sink marks estimate
Sink marks great
Radius Comment ( ):
OK, area is located at non-visible area.

20. MOLDFLOW ANALYZE ： Deflection all effects
Radius Comment ( ):
Let’s keep current geometry and see the actual deflection after off tool. Foresee this can be improved by adding ribs (similar to opposite side while increase a little bit insertion force for PCBA.
deflection great
Reduced the sink mark factor(0.6%), The highest value of deflection is 1.06mm 。
