In the era of electronic switch trade manufacturers' confused advertising, our buyers are increasingly unable to get the guarantee of quality and reliable 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 in order to get orders and choose low price to tempt customers, the products we buy cannot be guaranteed. Of course, these people are also making use of them. Now many customers are solution companies or small OEM factories. Because of their limited conditions, they can't buy more testing instruments for switches to verify products, which leads to various problems in mass production. Not to mention the delay in production, what's more important is the delay in the delivery of final customers, and more seriously, the loss of a brand. After Wei Zexi's event, baidu also began to carry out actual certification for all walks of life, but it takes a certain amount of time, so in this short time, please pay attention to select a professional touch switch manufacturer.
Because we have lived in this industry for many years, our company often receives calls from customers, who are looking for the touch switch imported from Japan. In fact, we all know that customers do not need to choose products imported from Japan for their product positioning. 1、 Why do customers choose Japanese products because of the long delivery time, the limitation of product packaging and the direct increase of cost? Because they found a lot of so-called factory, the result is not even a basic reflow soldering chip. At present, the staff of the company are all from the post-85s. Their main resources come from the Internet. They need cash to buy online. In case of any problem, they can't find the manufacturer to settle the claim and raise their own production.
Many customers ask me if your chip touch switch can be reflowed. I said this is what age, Hello, ask such old questions. The temperature resistance of the touch switch is one of the necessary conditions for us, and it is also the most fundamental quality assurance. Let's talk about the phenomenon that the switch can't pass the reflow soldering.
1、 After the reflow soldering process, the switch is stuck and cannot be pressed.
2、 After the reflow soldering process, the switch can not be pressed on time due to bad handle.
3、 After the reflow soldering process, the resistance of the switch is high and the conduction performance is poor.
4、 After the reflow soldering process, the handle of the switch blisters or the surface blisters, which affects the appearance and assembly.
5、 Switch after reflow soldering process, all kinds of problems together, make you a mess.
According to the appeal of several bad reasons, we next, to analyze the existence of the problem and how we can protect the reflow soldering chip touch switch. The first problem is that the switch will be stuck after reflow soldering. The plastic body is not heat-resistant, which leads to plastic melting and deformation. The poor sealing performance of the plastic body leads to flux entering directly. The second problem is that the handle of the switch is poor, and the manufacturer uses poor shrapnel. The shrapnel deformation after reflow soldering is high temperature, which directly affects the handle. The third problem is that the terminal electroplating of the switch is not good, and the contact resistance is poor There is a chemical reaction after the flux, which directly leads to the high resistance and directly affects the performance; problem 4: the plastic body of the switch is made of high-temperature materials, but the plastic material is not dried before production, which leads to the blistering phenomenon of the plastic after reflow soldering; problem 5: the switch itself is a rotten product, and as a result you buy it, you understand the consequences. In order to effectively prevent the discovery of the above problems, we all control each production link one by one and use high temperature resistant LCP materials for production, please rest assured to use.
