The reflow welding process of touch switch is very good. What is the better place to be respected? Let's learn more about these aspects in detail.

In the network era of electronic switch trade manufacturers' chaotic advertising, our purchasing manufacturers are increasingly unable to get quality assurance and credible business language. When we are used to looking for materials and switches, we will inevitably be fooled by some non manufacturers and low-end manufacturers. When some manufacturers give up quality and choose low price to tempt customers in order to get orders, the products we buy cannot be guaranteed. Of course, these people are also used. Now many customers are solution companies or small-scale OEM factories. Because of their limited conditions, they can't buy more testing instruments for switches to verify the products, which leads to various problems in mass production. The more important thing is to delay the delivery of the final customers, and even more seriously, lead to the loss of a brand. After Wei Zexi's incident, baidu also began to carry out practical certification for all walks of life, but it will take a certain time, so please pay attention to select a professional touch switch manufacturer in this short time.

Because we have lived in this industry for many years, our company often receives calls from customers, all of whom are looking for the light touch switch imported from Japan. In fact, we all know that customers do not need to choose the products imported from Japan. 1、 Product delivery time is long; second, product packaging restrictions; third, the direct increase in cost, why do customers choose Japanese?  Because they found many factories called manufacturers, they couldn't even use a basic reflow soldering chip. At present, the company's employees are all from the post-85's to purchase. The main resources are from the Internet. They need cash to purchase online. In case of any problem, they can't find the manufacturer to settle the claim and raise their own production.

Many customers asked me if you can reflow your chip by touching the switch. I said what time it is. How do you ask such old-fashioned questions. The temperature resistance of light touch switch is one of the necessary conditions for us, and also the most fundamental quality assurance. Let's first talk about the concentration phenomenon that the switch can't pass reflow soldering.

1、 After the reflow welding process, the switch is stuck and cannot be pressed.

2、 After the reflow welding process is completed, the switch has poor hand feel, and it can not be pressed on time.

3、 After the reflow soldering process, the resistance of the switch is too high and the conduction performance is not good.

4、 After the reflow welding process, the switch handle blisters, or blisters on the surface, affecting the appearance and assembly.

5、 After the reflow welding process is completed, all kinds of problems come together and make you very anxious.

According to several bad reasons of the appeal, let's analyze the existence of the problem and how we dongkun can protect the over reflow soldering chip touch switch. The first problem is that the switch will be stuck after reflow soldering. The problem is that the plastic body is not resistant to temperature, which causes the plastic to melt and deform, and the sealing performance of the plastic body is not good, which causes the flux to enter directly. The second problem is that the switch handle is not good, the manufacturer uses poor shrapnel, and the deformation of the shrapnel after reflow soldering directly affects the handle. The third problem is that the terminal of the switch is not well electroplated After arriving at the flux, there is a chemical reaction, which directly leads to the high resistance value, which directly affects the performance; problem 4: the plastic body of the switch uses high-temperature materials, but the plastic materials are not dried before production, which leads to the foaming phenomenon of the plastic after reflow soldering; problem 5: the switch itself is a rotten product, so you buy it, and you understand the consequences. In order to effectively prevent the discovery of the above problems, dongkun controls each production link and uses high temperature resistant LCP material to produce one by one.
