When using the touch switch 6 x 6, you may encounter some problems. What are the specific problems? Let's take a look together.

1. The resistance value is high.
At present, many customers are not very familiar with the resistance value of patch light touch switch 6 *6. Generally, the resistance value of our switch is controlled below 30 m Euro, so the contact performance and life of the switch are very good, but some switches have higher resistance value after furnace temperature and life test. If the resistance is high, it means that the contact area between the shrapnel and PIN foot of the switch is too small, and the contact area is too small to cause the switch to be contacted. Once the switch is not contacted, it will be bad.
Therefore, we should be cautious about the resistance of the switch, the shrapnel and PIN foot for plating requirements are relatively high, plating resistance will be low. After the life test, the surface of the shrapnel will be worn. If the electroplating is thin, the resistance will be high and the switch will be bad.
Two, adhesion:
Ultra-thin patch light touch switch 6 *6 is generally known as thin film switch, thin switch needs thin film coordination, so as to achieve true thin. However, many films have poor temperature resistance and will fall off after the furnace. Our professional term refers to adhesion, in fact, is the film stickiness, imported PI film has a good control of this point, its adhesion is 400g, very in line with the use of switches, how light will often fall off, if too heavy switch will not move, many manufacturers in order to save costs to choose cheap domestic PI film, the switch is very easy. There is a problem of adhesion. It is recommended that you consult the manufacturer before buying.
The same is true for the patch light touch switch with point 6 * 6. It is very difficult to point out the point with imported rubber. If the point is made in China, then your problem will come. A penny a penny a penny a penny, I suggest you choose the manufacturers with high quality requirements, give yourself a choice of satisfactory manufacturers.
Three, do not press after furnace.
A good switch, after reflow welding experience, it can not press, poor. Many customers are also responding to this problem, so what caused it? The patch switch is tightly attached to the PCB, and the PIN foot will be solder paste. If the hole of the steel mesh is slightly larger, the solder paste can easily flow into the inside of the switch. If there is foreign matter in the inside of the switch, it will certainly affect its journey. The most common thing is to press it still. Another situation is that the sealing performance of the switch is not good, flux flows into the inside of the switch, so the problem arises.
Therefore, it is suggested that customers should pay attention to this problem in the production process. In particular, our side button patch touch switch 6 * 6 is the most frequently encountered situation, sometimes it is difficult to explain with customers, there are some experienced factories will be very good to eliminate this problem.
Four, the lid fell off:
In the production process, there will be a customer response switch lid will leak phenomenon. How did a good switch cover fall off? First, we need to understand the structure of the switch. The cover of the switch is on the back cover. This is a constant production process for thousands of years.
You will find that the cover is fixed by four riveting points on the base, so as long as the four riveting points are loose or the riveting points shrink or deform after high temperature, the cover will fall off. Preventive cover only pays attention to the following two problems. One base should be made of heat-resistant material, the second riveting point should be riveted and fixed well, and the above two problems should be solved perfectly.
Five. Handle:
Many customers have been responding, many suppliers send samples feel very consistent, but when it comes to mass production feel different. In fact, this problem is very common. We all know that the handle and push force of the switch are controlled by shrapnel. We often say that shrapnel is divided into phosphorus-copper shrapnel and stainless steel shrapnel. At present, many manufacturers choose phosphorus-copper shrapnel in order to save costs. The price performance of phosphorus-copper shrapnel is relatively high, which is also the reason why it is widely used. However, the phosphorus-copper shrapnel will change after the furnace temperature, and the shrinkage is serious, which will lead to bad hand feeling.
The use of stainless steel shrapnel will not have this problem, but the cost of stainless steel shrapnel is relatively high, leading many manufacturers to take risks in choosing phosphorus-copper shrapnel, so when purchasing patch light touch switch 6 *6, we must ask the next question clearly.
Six, light press and non conduction:
Many consumers, in the use of products, often find that the button pressed does not respond, to press very hard, the product has functional response. Because our switches are exposed to the air, many finished products are not sealed, consumer electronic products are required to heat. In wet weather, the shrapnel of the switch is easily oxidized, and the contact performance after oxidation is not as good as before, that is, there is a problem of light press and no conduction.
Many consumers have also dismantled the switch and found that there will be a small black spot on the shrapnel, which is the effect of shrapnel oxidation. Therefore, it is suggested that the electronic products we do not normally use should be placed in a relatively dry place and the prepaid electronic parts should be oxidized.
