When the light switch is connected with the lamp, it needs to be welded. How many soldering methods are there in detail? We will give you a detailed introduction below.
Light touch switch package with lamp includes SMD chip package and DIP plug-in package. The main categories include environmental protection and high temperature resistance, chip type, plug-in type, light touch switch with lamp, waterproof belt light touch switch series, light touch switch with lamp refers to the use of small power, light touch button switch can achieve switch on the element. When the hand is loosened, the switch will be disconnected immediately. The inner part of the switch will be disconnected mainly by the elastic force of the metal shrapnel. It is used in security products, audio-visual products, money checking pens, remote control, digital products, household appliances, computer products, laser pen keys and so on.
The following methods are used to weld the light touch switch with the lamp. The details are as follows:
1. One by one manual welding, the advantage is that it can accurately grasp the welding of each component, the disadvantage is too time-consuming and laborious.
2. Wave soldering with pins has the advantages of low price, time-saving and labor-saving, but the disadvantages are: as the components become smaller and PCBs become denser, the possibility of bridging and short-circuit between solder joints increases.
3. The advantage of this process is that the temperature can be easily controlled, the oxidation can be avoided in the welding process, and the manufacturing cost can be easily controlled. The disadvantage is that the solder collapsing will occur in the welding heating process, which occurs in the preheating and main heating situations, when the preheating temperature is in the tens to one. Within a range of 100, as one of the components of solder, the solvent will reduce the viscosity and flow out, if the flow is strong, it will also extrude the solder particles out of the welding zone gold particles, in the melting process, if can not return to the welding zone, will also form a retained solder ball.
As the name implies, the light touch switch is to use a simple and portable touch mode to achieve smooth operation of the circuit machine, which greatly facilitates people's lives, but also reduces the heavy physical burden of people, so as to be able to efficiently benefit people's production and life, then light touch switch research Now, let us take a look together.
First of all, the light touch switch with light can give people light when they use it in daily life. It is often used in daily photo equipment. If the light is on all the time, it is very energy-consuming, which is not conducive to saving power resources. So people will design the light touch switch with light in daily photo products, as long as the basis is based on. It is very convenient and environmentally friendly and energy-saving. Light touch switch with light is widely used both in China and abroad. A large part of it is used in the lighting control system and in daily life. Lighting systems pay great attention to saving resources, so the light touch switch with a delicate structure, will not occupy too much space.
Secondly, the light touch switch can be used in the alarm system or security equipment, because people's quality of life is constantly rising, but also pay more and more attention to the privacy and security of living space, so it is necessary to have a very reliable and do not affect the daily life of the defense system to ensure their own safety of life, with lights. Light touch switch with light touch switch meets people's unique requirements. It is light weight and small structure, but it can play a huge role in the daily alarm system and security equipment, because it only needs a simple touch, can trigger the alarm system, so that the system issued an alarm or a series of related measures. People's personal safety and property safety play a strong protective role.
Light touch switch with lamp is also used in the modern production process of today's large factories. Now many production processes have reached the full automatic standard. Without heavy labor, we can create high-quality products in a short time. Both quantity and quality are greatly improved. All of these naturally must be light with lamp. Touch the important role of the switch, it can help people to operate a unified machine, do not need heavy manual labor, just need to touch a few buttons according to the need to control a whole production line of products, can be said to be simple and efficient and not easy to make mistakes, and the most important thing is to completely liberate the people. Hands, so that people really enter the high-tech production and life.
