How to check the quality of a Membrane Keypad?

When checking the quality of a Membrane Keypad, it is important to align the panel with the line after inspection. Ensure that the diagonal lines on the corners of the Membrane Keypad remain aligned. If there are bubbles in the adhesive, scrape them off before applying. After application, pay attention to maintaining bright windows. For images of the membrane panel, use an LED to check if the membrane panel is lit or not, and for any uneven brightness issues. It is necessary to compare these with samples.

Each product undergoes continuous sampling for life testing (typically requiring 500,000 cycles to confirm as a qualified product). First, visually inspect the appearance for any defects and ensure that the silk screen printing is intact.

Then, according to the principle of panel lines, use the viewer to check one by one. Carefully observe the lines of the Membrane Keypad, which should not have any open circuits, short circuits or excessive resistance. The most important and core thing is to pay attention to checking whether the Membrane Keypad is good or bad by checking if each button on the panel responds sensitively (especially for those with spring plates, it's necessary to check if they work properly).

1. Outstanding appearance, smooth surface, average gloss, no mechanical operation, no scratches, inclusions or discoloration.

2. Good weather resistance, no deformation, cracking, aging or discoloration under certain natural environmental conditions. For the most common chemicals, it can reach the surface and must have better resistance to chemicals such as alcohol and ether.

With the continuous development of our science and technology, various electronic products in our lives are constantly being updated. Not only do we have higher requirements for their functions, but also new demands on their appearance. So, what methods can be used to decorate the keypad panel? Below, the keypad switch panel manufacturer will take us to understand the relevant product knowledge.

Membrane Keypad decoration is not just for aesthetics, but also for the functionality of petroleum products. Membrane Keypad panels are a new type of electronic product. They can effectively improve the dustproof function of products and enhance their appearance. In fact, touch panels and PVC panels have some similarities, with different appearances but each with its own characteristics. Compared to them, spray paint panels and other panels will be much worse.
