Touch switch packaging method and the use of matters needing attention

2023-10-25

There are three packaging methods for tact switches: SMT patch package, bulk artificial plug-in, and DIP plug-in tape package. Precautions when using the touch switch: When the terminal is welded, if the load is applied to the terminal, it will be loose, deformed and the electrical characteristics may deteriorate due to different conditions. Please pay attention to it when using it.

Test method for tact switch performance

2023-10-25

The touch switch is small in size and belongs to standard parts. The size and related parameters must be combined with industry standards, and the color is relatively single; the touch switch can also be customized according to the requirements of the guests, and the use is more convenient and flexible. We can test the performance of the tact switch in the following ways according to the different tact switch series. The main test touch switch welding resistance, cold resistance, temperature resistance and moisture resistance.

Tactile switch selection method

2023-10-25

Tactile switch is small in size and is a standard part. Its size and related parameters must be combined with industry standards and its color is relatively single. Tactile switch cannot produce functions alone and must be used in conjunction with PCB circuit board to form a complete open control system.

Introduction and Common Problems of Micro Switch Welding

2023-10-25

The manual welding of micro switches is characterized by the ability to finely grasp the welding of each electronic device, but the disadvantage is that it is excessively time-consuming and laborious. Pin wave soldering, the advantage of cheap price, cost savings. Disadvantages also with the current stage of electronic devices become smaller and PCB more and more dense, in the spot welding between the bridge and short circuit failure probability also increased. The advantage of this kind of processing technology is that the temperature is easy to control, the air oxidation can be avoided in the welding process, and the raw material cost is easier to control. The disadvantage is that solder edge collapse will also occur in the welding heating process, which occurs in both heating and main heating fields.

Three major problems and solutions of side touch switch

2023-10-25

One of the common accessories of electrical appliances in life is the switch, which is used to control the disconnection and connection of the power supply. However, with the development of science and technology, various types of switches have also appeared. Side-touch switch is a new type of switch. It is also called a button switch. It appeared in other early days. When used, it is mainly to control the connection and disconnection of the power supply by meeting the operating force conditions. Next, I will summarize some of its own problems and solutions.
