Breakthrough technology tends to dominate the headlines, such as button batteries boxes components often overlooked, although they are of concern in support of the work of button batteries battery for laptop play an important role. The battery box may be because, like vibration, heat, shock, humidity and corrosion reasons such as failure, design engineers in the development of power management solutions to address these practical problems, when faced with more and more severe challenges. By focusing attention on the following criteria, engineers are able to optimum cost to achieve product reliability.
Button battery to maintain power and the demolition
Well-designed button battery pack must be resistance to shock and vibration while maintaining sufficient flexibility in order to achieve convenient battery replacement. Unfortunately, these standards are often contradictory, because a better retention is equivalent to more difficult to demolish. Please search demolished with a convenient battery-function battery pack.
In the field test the battery box is particularly important. If the coin cell battery box in your hands, rather than welding in the printed circuit board and surrounded by other components and shell, then the demolition of the battery is usually much easier.
Durability
For those in the product’s life expectancy may require frequent battery replacement applications, the durability of the battery case is particularly important. If the battery box because the battery insertion and removal in the process of increasing the use of high wear and tear of fixtures, then the problem will be IBM FRU 92P1141 battery， IBM ThinkPad R32 battery， IBM ThinkPad R40 batteryexacerbated. If your application requires relatively frequent battery replacement, look for the battery recycling box tested the frequency of use.
All the battery box should have the polarity protected, so that the battery is not correctly inserted when no contact. If you anticipate the need to replace the battery several times, then it becomes more important.
Electrical conductivity and corrosion resistance
Overheating and excessive exposure to moisture environment, corrosive chemicals, or air-borne pollutants, often may lead to the accumulation and corrosion-related issues, which could have a negative impact on electrical performance. In order to minimize these effects, please choose to use corrosion-resistant material of the battery box. The existence of different electrochemical properties of metal corrosion problems could further deteriorate, leading to electro-chemical corrosion. Through the use of insulation or gold-plated, you can minimize these effects.
Good electrical conductivity of metal, such as gold, may lead to unexpected additional advantages. They have less friction, thereby reducing the insertion force. Although the shape of shell and contact are the main source of insertion force, but when all other factors are equal, gold and tin and copper, similar to the material than the power required for even smaller.
Required tolerance
Even the battery performance, comparable to the size specifications may vary. For example, according to industry standards, CR2032 button batteries may be the height of ± 0.3mm or 10% of the total height of the range. Therefore, the button battery pack able to adapt to changes in the normal height is not compatible top battery with the battery will not accept this is critical. Connection too loose can not be accepted because it would damage the electrical performance.
If the battery is the factory-installed, but designers can control the use of batteries, then the problem is not too serious, but if the end user can purchase replacement batteries, then it should support the entire range of cell sizes.
Solderability requirements
The welding process can also affect the choice of the coin cell battery box. For example, the need for SMT soldering button battery pack should be made of high-quality LCP plastic, which can provide superior high temperature insulation strength, and can withstand 300 ℃ lead-free reflow soldering process temperature. On the contrary, wave soldering process requires a lower strength of the material, enabling the use of PBT / Nylon plastic insulating material. This material at 25 ℃ to provide 5s to reach 560V/mil insulation strength, with the right chemicals and solvents resistance can work in a wide temperature range, has excellent thermal cycling performance, as well as the smallest 5000MΩ of insulation resistance.
Wrong choice materials, manufacturing processes may lead to withdrawal of a number of sub-production line. Should require a comprehensive product test data to ensure that the button battery pack to meet or exceed the ANSI/EIA-5405000 standards, and all the raw materials used are of excellent quality.
Production Integration
For high-volume production wholesale electronics and design products, Button battery box should use standardized reel packaging available to pick and place production lines. In addition, should also take into account the applicable government or industry regulatory compliance requirements, such as RoHS and lead-free requirements.
