Today we will explain some common problems of touch switch for you! We have summarized some problems, such as plug-in, patch, side press, light, waterproof, ultra-thin and so on. Today we will introduce them to you one by one! Welcome the broad colleague plagiarizes, and reprints.

 

1、 Common problems of plug in touch switch

 

As we all know, plug-in light touch switch is suitable for manual welding and wave soldering, because its welding process for temperature resistance performance is not very high, which gives a lot of bad opportunities to manufacturers. In order to save cost, many defective manufacturers have replaced the original PA66 plastic base with POM material, even if the material is changed, and added recycled materials according to different proportions. As a result, many of our customers find environmental protection problems, blistering on the switch surface after wave soldering, key sticking and other problems.

 

2、 Common problems of chip touch switch.

 

Chip touch switch is one of the common switches. In this era of difficult recruitment, it is machine that can save labor cost, so chip touch switch is one of the best choices. However, many customers also worry about it, because once there is a problem with the switch, it is difficult to repair it. In fact, this kind of switch is very simple to do well. The electronic materials are all PA9T or LCP materials. These two materials are not difficult for reflow soldering process. In order to save cost, some manufacturers change to PA66 or more low-end materials, so problems will follow. The common problems of the chip touch switch are: the temperature resistance of the switch, the attenuation of the handle, the melting of the key handle, the blistering of the switch base, the non conduction of the switch when it is pressed lightly, the key sticking and so on.

 

3、 It is easy to immerse rosin by touching the switch.

 

Side touch switch is often used as a side key in our digital products. Many engineers choose it for its beauty and portability. The design idea of the front end is very good, but in the process of production and use, our production personnel began to have a headache, because it is easy to immerse rosin and other problems by pressing and touching the switch. Let's analyze it today. First of all, the pins of the side press switch are interconnected with the inside. This is the key, because our pins need to be soldered with tin. If the precision of the product mold of the switch is not enough, there will be a tiny gap between the pin and the plastic body, which will leave us the opportunity of rosin. Second, the engineering is the welding of the switch It's also very important to draw the board according to the drawings provided by the manufacturer, and remember not to be too large or too small, because this will directly affect the amount of tin on the back. We suggest that customers should control the amount of tin on the back between 0.1-0.13 as far as possible, which is the most appropriate. The re switch is a very precise product, and the materials we use are also very important, as we can see above More than once, we must use materials with high temperature resistance to avoid plastic material deformation after welding process, which will lead to switch sticking and other problems.

 

4、 Waterproof touch switch is not waterproof.

 

Waterproof touch switch is waterproof as the name suggests, but what should we do if it is not waterproof? It's very simple to change the switch. Haha, what we said is very simple, but it's really that simple, absolutely not. A product should be made waterproof, and its structure should be waterproof at the beginning of design, that is to say, the product should be made into a seal, because the button handle of the switch needs to be exposed, which also needs mechanical travel, so the switch itself must be waterproof, otherwise the whole product will be scrapped. First of all, let's talk about how to deal with this waterproof problem. What waterproof switch has to do than ordinary switch is its sealing, so how do we do it? The common waterproof switch is to add silica gel in the middle of the contact between the key handle and the switch shrapnel, that is to say, when water enters the inside of the switch, it can protect the shrapnel and the gun point from entering, so that the switch has the waterproof effect. So the waterproof switch will not be waterproof is very simple, that is, the matching degree of materials, the matching of electronic waterproof switch parts is very perfect, so there will be no problem of waterproof. How do we test the waterproof performance of waterproof touch switch? We will test our switch according to the international waterproof grade test method. Every batch will be sampled and tested, and 100% good products will be shipped. We suggest you choose our waterproof switch.

 

5、 Light touch switch is not temperature resistant and LED color error.

 

The light touch switch is a kind of more complicated switch in this kind of switch. Because it has the function of switch and the effect of breathing light, it is more difficult and expensive. We know that in order to show the effect of the switch with light, transparent PC material will be used at the position of the key handle. The advantage of this material is that it will make the product very beautiful to use, and the effect of LED will also be shown, but its temperature resistance is really poor, so it is generally necessary to use touch welding or use some relatively low melting point solder paste. Many electronic products have more than one switch, so the problem is that if a product has 10 light touch switches, its color error is relatively large, so what should we do? The problem is relatively simple. Electronics do a better job in this aspect, because we use Taiwan's LED lamps, and the LED products produced in Taiwan have high price, high stability and high performance The color error of the product is small, and the luminous life is high, so it is recommended to use Taiwan or Japan led lamp manufacturers.

 

6、 Tap the switch frequently asked questions.

 

Why should we introduce the touch switch? Why not? The reason is very simple, is a professional manufacturer of touch switch, let's talk about the problems of the products!

 

First, the materials used for electronic touch switches are all Taiwan or imported materials, so the problem lies in the delivery time, which is usually a long time.

 

Second, the speed of proofing is slow. Because the company stipulates that the samples that exceed a certain period of time need to be scrapped, they can meet the requirements of customers and pass at one time. Therefore, generally, the production samples will be arranged according to the requirements of customers, and there are no stock samples.

 

Third, the price of products is high. Electronics is located in Dongguan, which is not suitable for the traditional production industry. This will affect the cost. Is this the key point? The key point is that there are many switch inspection processes, the production process is more detailed, and the cost of using imported materials will be higher. So if you want to accept its quality, you have to accept our price.
