Tips:

Consumers How to choose the right box Button batteries do? The following methods can provide a reference:

Consumers are accustomed to the main care products, such as Button batteries cartridge such elements often neglected, although they concern the support of the work Button batteries plays an important role. Battery pack may be because, like vibration, heat, shock, moisture and corrosion and failure of this reason, the design engineers in the development of power management solutions to deal with these realities when faced with growing challenges. By focusing on the following criteria, engineers were able to achieve optimum cost product reliability.

Button batteries retention and removal. A well-designed box Button batteries must withstand shock and vibration while maintaining sufficient flexibility to achieve easy battery replacement. Unfortunately, these standards are often contradictory, because it means better retention more difficult to remove. Please look for easy battery removal function with the battery compartment.

In the field test battery box is particularly important. If Button batteries box in your hands, rather than soldered on the printed circuit board and surrounded by other components and the housing, then remove the battery will usually be much easier.

Button batteries box durability, for the expected life of the product that may require frequent replacement of battery applications, the durability of the battery case is particularly important. If the battery pack because the battery in the process of insertion and removal of the increased use of high wear fixture, then the issue will be further intensified. If your application requires a relatively frequent battery replacement, look for the battery case cycle times tested. All battery pack should have polarity protection, so that the battery is not properly inserted when no contact. If battery replacement is expected to take several times, then it becomes even more important.

Button batteries box conductivity and resistance to corrosion, exposure to excessive heat and excessive moisture, corrosive chemicals, or airborne pollutants among the usual accumulation may lead to problems associated with corrosion, which may give negative impact on electrical performance. To minimize these effects, select the Use corrosion-resistant material manufactured battery compartment. Exist electrochemical properties of different metals corrosion problems may worsen, leading to galvanic corrosion. By using an insulator or gold, you can try to reduce these effects.

Button batteries required tolerances cartridge, even if a performance comparable to the battery, sizes may vary. For example, according to the industry standard, CR2032Button batteries of ± 0.3mm in height may be 10% of the total height or range. Therefore, Button batteries boxes to adapt to changes in the normal height will not accept incompatible battery this is very critical. Too loose connection is unacceptable because it will damage electrical performance.

Button batteries box weldability requirements, the welding process will also affect the selection box Button batteries. For example, you need to SMT soldering Button batteries box should be made from high quality plastic LCP, which can provide superior high temperature dielectric strength, and can withstand 300 ℃ lead-free reflow soldering process temperatures style. On the contrary, the wave soldering process requires lower strength materials, enabling use of PBT / Nylon plastic insulating material. This material can be provided at 25 ℃ 5s achieve 560V/mil insulation strength, with the chemical substance and solvent resistance, can work in a wide temperature range, have excellent thermal cycle performance, and minimal 5000MΩ of insulation resistance.

Wrong choice manufacturing process materials may lead to many production lines sentenced retreat situation. Should require comprehensive product test data to ensure that the box Button batteries meet or exceed ANSI/EIA-5405000 standards, and all the raw materials used are on a good quality in order to meet environmental requirements.
