Thin Film Switch IP65 4x4 Matrix 50VDC Light Touch Keyboard
Use of membrane switch conductive circuit: widely used in switch panels of household appliances,
instrumentation, mechanical electronics and medical equipment,
factory name/trademark OEM, etc., fundamentally changing the
defects of aluminum panels and other traditional panel materials,
becoming One of the most ideal new panels in modern times.
The characteristics of the film panel: It is a kind of word mark and trademark that integrates decoration
and functionality in an international fashion in recent years.
Print established graphics, text descriptions, transparent windows,
etc. on flexible plastic materials such as PVC, PC, PET, etc., and
paste different types of double-sided tape to make plastic products
used for identification and protection. The film panel has
beautiful appearance, clear pictures and texts, and good
airtightness. It has the characteristics of waterproof,
anti-deformation, anti-pollution, anti-high temperature and strong
viscosity. Widely used in intelligent electronic measuring
instruments, medical instruments, computer control, CNC machine
tools, electronic weighing apparatus, post and telecommunications,
copiers, refrigerators, microwave ovens, electric fans, washing
machines, electronic game consoles and other industrial and
household appliances products.
The film sticker uses different materials, which determine its
price and performance. The biggest feature of the film panel made
by the silk screen process is:
1. Clear and intuitive graphics and text, and can adapt to
different planes and curved planes.
2. The choice of different materials can make PVC, PC, PET and
other materials.
3. The film panel has the characteristics of waterproof,
anti-deformation, anti-pollution, anti-high temperature, and strong
viscosity.
4.Silver paste migration: after 56 hours at 55℃, temperature 90%,
10mΩ/50VDC between the second lines; No oxidation and no impurities
on the silver paste line
Silver paste line width ≥ 0.3mm, minimum interval 0.3mm, line burrs
<1/3, line gap <1/4 line width
