1, the position of the screw: It is possible to carry the position of the fastening pressure, and there is a support hole around, and the corresponding housing needs to be pressed.
2, the side surface of the plastic housing is paralleled with front or ground, as well as the right angle reinforcement piece
3, the application of metal beams at the card, (whose design, corner of the beam, the screw hole position on the beam, the outer shape of the beam)
4. Design of the plastic housing support column.
5. Tayer of border.
6. Use of the support surface between the parallel surfaces.
7, design of the side frame of the housing
8, the design of the power switch: A, the connection of the plastic body with electronic switch; B, the two-stable design of the switch; C, the option of electronic switch itself
9, the actual situation of the extension, online interface. It is necessary to meet the performance and use requirements of the design subject, and a method of electromagnetic isolation can be used for a often connected portion.
10, wiring problem of the edge of the PCB.
11. The PCB pattern of the conductive rubber button.
12. Tail design of the same shape button.
13. Plastic hard press connection problem with conductive rubber.
14, the alignment problem of the display, try to use the outer frame of the display device itself, there is a parallel surface contact.
15. Fixed speakers / microphones, fully utilize the outer frame of the element.
16. Support problems of long-range conductive rubber buttons, use multi-edge holes, do not use straight wall holes.
17. Install the problem of the side button on the housing
18. The shape design of the light guide column.
19. The positional relationship between the headphone jack is the same as the plastic housing.
20. The slit problem between the upper and lower housings. Seamless design and seamless design. For a seamless design, the upper and lower housing contacts can be more flexible, and the thickness of the electrical portion in the housing can be adjusted.
