Today, we introduce to you the common problems of plug-in touch switch, patch touch switch, side press touch switch, waterproof touch switch and light touch switch. See below for details.
Dongkun Electronics as a professional level of light touch switch manufacturers, today we will explain some common problems of light touch switch for you! We summarized some problems, whether plug-in, patch, side press, with lights, waterproof, ultra-thin and a series of switches. Today we will introduce them to you one by one. Welcome colleagues to copy and reprint.
1.As we all know, the plug-in light touch switch is suitable for manual welding and wave soldering, because its welding process for temperature resistance is not very high, which gives many bad manufacturers opportunities. In order to save costs, many poor manufacturers have replaced the original PA66 plastic base with POM material, so that the material can be changed, and recycled materials can be added according to different proportions. As a result, many of our customers find problems of environmental protection, foaming on the switch surface after wave soldering, key card and so on.
2. Common problems of patch light touch switch.
Patch lightly touch switch is one of the common switches. In this era of difficult recruitment, it is the machine that can save labor costs. So patch switch is one of the best choices, but many customers are also worried about it, because once the switch has problems, the problem of repairing difficulties will arise. In fact, this kind of switch is very simple to do well. The materials used by Dongkun Electronics are PA9T or LCP materials. These two materials are not at all difficult for reflow soldering process. In order to save costs, some manufacturers have changed to PA66 or lower-end materials by themselves, so the problem will follow. The common problems of patch light touch switch are: temperature resistance of switch, feel attenuation, melting of key handle, foaming of switch base, light press of switch, sticking of key, etc. It is very complicated. Therefore, to choose the switch without problem, it is suggested that Dongkun Electronics be the best choice.
3. It is easy to immerse rosin by tapping the switch on the side.
Side-click switch is often used as side-button in our digital products. Many engineers choose it for its beauty and portability. The design of the front-end is very good, but in the process of production and use, our producers begin to have a headache, because it is easy to immerse rosin by pressing the switch on the side. Let's analyse it today. First of all, the pins of the switch are connected with each other inside. This is the key because our pins need to be soldered with tin. If the precision of the switch's product die is not enough, there will be a small gap between the pins and the plastic body on the matching, which will leave us rosin opportunities; secondly, the engineering is to draw the welding of the switch. Disc time is also very important, according to the drawings provided by the manufacturer to draw the board, remember not to be too big or too small, because this directly affects the amount of tin on the back, Dongkun Electronics suggests that the amount of tin on customers should be as far as possible controlled between 0.1-0.13, which is the most appropriate; re-switch is a very sophisticated product, the materials we use are also very important, above. We have also said more than once that it is necessary to use high temperature resistant materials to avoid problems such as switch card keys caused by plastic material deformation after welding process.
4. Waterproof light touch switch is not waterproof.
Waterproof light touch switch, as its name implies, is waterproof, but what 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. If a product is to be waterproof, its structure should be waterproof at the beginning of design, that is to say, the product should be sealed, because it needs to be exposed to the outside of the key handle and mechanical journey, 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 the waterproof switch needs to do is to seal it. So how do we seal it? The common waterproof switch is to add silica gel in the middle of the contact between the button handle and the switch shrapnel. That is to say, when water enters the inside of the switch, it can protect the shrapnel and the shot point from entering, so the switch has waterproof effect. So the waterproof switch will not waterproof problem is very simple, that is, the matching degree of materials, Dongkun electronic waterproof switch parts matching is very perfect, so waterproof is not a problem. How do we test the waterproof performance of waterproof light touch switch? We will test our switch according to the international waterproof grade test method. Each batch will be sampled. Only 100% of the good products will be shipped. We suggest you choose our waterproof switch.
Fifth, color error problems such as light touch switch temperature resistance and LED.
Light touch switch with lamp is a more complex switch in the type of switch. It has both the function of switch and the effect of breathing lamp, so it is more difficult and expensive to do. We know that in order to show the effect of the light switch, transparent PC material will be used in the position of the key handle. The advantage of this material is that it will make the product use very beautiful LED and so on.
