Test is mainly according to the various buttons to see the finished product machine if there is a corresponding reaction membrane switch function is normal, the following introduce the membrane switch and thin-film panels commonly used materials:
PVCThin film materials prices lower, which is aboutPCHalf of the material, when the production of civil affordable products, if you choosePVCMaterials, can reduce the production cost, at the same timePVCThe ductility of material is better, can use cold processing three-dimensional graphic.Smooth surfacePVCPlate thickness in general0.5Millimeter above, there are both two sidesPETOr tape to protect water, most used to make decorative panel;On the surface of the sandPVCMaterial thickness in general0.3Millimeter, it usually to scale sheet of supply and no coil.
Suitable for making panel layer thin film materials, according to their kinds, we know from the above content oftenPC、PVC、PETThree;According to the surface state and the sand surface (semi-permeable3Ming film) with smooth surface (transparent film).
PCMaterial physical properties and chemical properties of composite indicator is good, the adaptive ink more widely, also is the most common application layer membrane switch panel materials.PCMaterial has the distinguish of sand surface and smooth surface, choose the reason of sand surface material because of the use of membrane switch is electronic product, more as a control panel of the control system does not want the light interference, and the surface of the sand surface shape only diffuse shaped, won't produce bright reflections;At the same time, due to the sand grain surface is disorder, have the function of the masking scratches, by contrast, glossy material don't have more features.
But as glossy material, once after printing on the back, the color will appear more bright is dazzing, in strong decorative requirements and do not need often touches, often choose smooth material panel, or for some display area such asLCDThe special needs of liquid crystal display and consideration, choose favourable smooth material.
Due to thePETThin film performance can be in generalPCFilm is replaced, reason for panel material is not too much, unless in some special occasions, such as the insulation, the springback, solvent resistance is under the condition of other film can't meet only a small number of applications.
