Engineers who do product solutions, or engineers who do PCB hardware often encounter a touch sensitivity debugging issue. Then, the acrylic touch panel is not sensitive or failed. What is the cause of this situation, let's analyze it.

1, ink, some ink exist in conductive ingredients, if a large area is printed, all characters are connected, become a conductive body, which is equivalent to all buttons in this touch panel being pressed, resulting in difficult to identify or even identify, The touch effect is naturally not good.

2, thickness, material thickness is one of the factors that affect capacitive touch effects. After testing, the thickness of the acrylic panel is preferably 1-2mm, and the effect of 5mm is deteriorated. The acrylic thickness is too thick, and it is too thin, and it is too thin and the appearance or rigidity. .

3, touch points and acrylic contact methods, contact sensing zone area can also affect touch effect, no contact is not tight, or the induction area will also affect the touch effect. The acrylic buttons are in contact with the circuit pins. Currently, like: spring type, soft rubber, spring conductive sheet, conductive cotton, flexible circuit board paste, etc., various methods are not very weak, engineers The specific product is measured after analyzing.

4. Particularly pay attention to, some customer products require electroplating mirror effect, always use non-conductive vacuum electroplating, remember, mirror effect points, non-conductive methods, if used wrong, may not touch.

In summary, if the customer needs to communicate with the acrylic panel factory engineer if you want to use it on the touch panel to achieve better results.
