What kind of PCB assemblies we can do? For PCB printed circuit board, it is conventional rigid PCB. That means the electric circuit layer will be embed by temperature,while coating with insulation printing, complete a basic electric circuit on substrate. Another one, some of required electric parts ,such as diodes, audions , capacitances,risistances,some of integrated chips even led chip,fixed on it. Like this, the mainboard will become an integrated control module unit. Added with burned running programme, it will become more and more automation and intelligent ! Sometimes ,such control module unit can work with membrane switch together, become User interface, so that offer more convenience and security to the end users better. By operating membrane switch, will control a big size machine to do some intelligent works, this will be our contributions for machinical and industry field, PCB assembly membrane switch PCB assembly electric circuit In some condition, customer need more high grade control panel to control equipments and devices, they maybe need a capacitive membrane panel to do some actions, we suggest that we will come this module unit with membrane touch screen, as long as using finger to touch the designed area, the equipment or device will execute some actions automatically. likes this , most of applications is selected by household and appliances field .
