The LCM (LCD Module) is a common component for the electronic products. Almost of the LCM was made by glass and it is brittle and break easily while hit or drop on the floor due to handle careless. As product design we will install a rubber gasket or cushion locate between the glass and plastic case or metal bezel to prevent it from squeezing due to press or careless hitting.
Although this kind of rubber gasket is a simple design but if the gasket didn’t design well then the installation will be a big challenge in manufacturer. We often see the gasket go outside of the display view area. If this is a touch panel product then it will result the touch function fail. If this kind of issue happens in filed then we will get big trouble.
Therefore, this article attempts to look for the rubber gasket design methods.
So, how EMS fabricate a PCB Assembly? It is almost automatic production line now through SMT or wave soldering process to solder the electronic components on the board to instead of hand soldering by iron. Of course, you still can hand solder all electronic components on the board as manual by yourself but you must take high risk for the poor solderability quality and can’t do it mass production. Besides, the 0201 small chip are hard to be hand soldered on board and some of the package that design the soldering pads under the package body can’t be hand soldered. For example BGA, QFN, LGA package.
As my personal feeling that Right-angle FPC ZIF connector is really more easily to use than Drawer type of ZIF connector. Even right-angle connector is good but do you know how to select a good design of this kind of right angle connector?
For almost of the frequency radio apparatus, the Printed Circuit board must design the shielding frame/can to prevent the EMI (Electromagnetic Disturbance Interference) effect. The regular design will apply one shielding frame to mount on PCB by solder and another shielding can to cover on the frame to isolate the RF. 
Last article I mentioned that my company applied the
