Coin cells have to be housed in battery holders that are fashioned in such a way as to make the process of replacing batteries simple and expedient. If product designers want their wares to be user-friendly for consumers, then coin cells have to be housed in battery holders that are fashioned in such a way as to make the process of replacing batteries easy. At the same time, the battery holder needs to have a design that is sturdy so that it can maintain a good connection to the cell despite being subjected to vibration and shock. This is because the connection between the battery and the cell is what allows the battery to function properly. This is essential in order to ensure that the battery stays charged throughout the process.
On the manufacturing side, the cell mounts need to be designed for automated pick-and-place production, and there needs to be a clear separation between the various connections. Additionally, there needs to be a clear separation between the various connections. Any design for mounting cells ought to incorporate various mounting options for the cells themselves. Surface mounting and through-hole mounting are both included in these configuration choices.
This article investigates the thought process that went into the creation of these battery holders, delves into the distinctive qualities and benefits that they provide, and covers the design considerations that ought to be taken into account when selecting coin cell battery holders.
The thought process that went into the development of the Snap Dragon. This is accomplished by restricting the amount of space that is available to the cell while it is housed in the holder, which prevents the cell from moving around freely. battery holder is still possible to remove the cover by using a simple snap, which makes it possible to change the battery in a way that is both quick and uncomplicated. This function was added to the product in an effort to make it as simple and straightforward to use as possible.
It is necessary for the component that forms the basis of the device to be able to withstand high-temperature reflow soldering processes during the manufacturing process. This component is made of liquid crystal polymer (LCP), and it serves as the device's foundation. The Snap Dragon holders are still able to keep a very low profile, adding an average of only one millimeter (mm) to the height of the coin cell battery above the pc board. This is because the Snap Dragon holders are made from a very thin plastic. Despite the fact that all of these features are incorporated into the design, this is still the case.
When examined more closely, it is possible to see that the coin cell battery holders that are manufactured by Snap Dragon use a two-piece design that is comprised of a snap-on battery retainer and a mating base, which together hold the cell. This design can be seen by looking at the coin cell battery holders that are manufactured by Snap Dragon. When inspected more closely, the coin cell battery holders that Snap Dragon makes feature this design. These holders are manufactured by Snap Dragon.
The Snap Dragon cell holder, in contrast to other high-reliability cell holders, was designed to make the process of user battery installation and replacement simple and uncomplicated. This was one of the primary motivations behind its creation. Other high-reliability cell holders, on the other hand, can make these activities challenging or even impossible for the user to complete, which stands in contrast to this feature.
The Snap Dragon coin cell holders are available in two different sizes, which enables the placement of BR/CR2032 and BR/CR1225 cells in either a horizontal or a vertical orientation, respectively, depending on your preference.
The component that is absolutely necessary for building.
Each Snap Dragon coin cell holder features a base that is crafted from premium virgin liquid crystal polymer plastic. This ensures that the holders are of the highest possible quality. Because it is both lightweight and durable at the same time, this type of plastic is an excellent choice for the material that will make up the base of the holder. In addition to this, it is temperature resistant, which means that it is able to withstand the high temperatures that are associated with the processes of SMT soldering. This is a significant advantage because it allows it to be used in a wider range of applications. In addition to this, the LCP base offers superior resistance to chemical attack and has the ability to withstand severe environmental conditions.
For improved electrical conductivity, the Snap Dragon base is built with dual pressure contacts that have a nickel plating over phosphor bronze and a flashed gold coating. These components are layered one on top of the other. These connections have a nickel plating over them. This provides an additional layer of protection against corrosion when it is brought into contact with the nickel-plated stainless steel electrodes of the coin cell. This is made possible by the extremely low electrical resistance, which enables an extremely snug fit and makes it possible to achieve this result.
Figure 3 reveals that the base that is currently being utilized is a Memory Protection Devices BHSD-2032-SM. This can be seen in the figure. The orientation of this surface-mount base is horizontal, and it was designed specifically for a CR2032 coin cell to be used with it. The dual pressure contacts are presented in a manner that is very easy to comprehend with the help of this diagram. These cell holders are a component of the Snap Dragon product line and are available for purchase as an option. Because it is equipped with bendable tabs, the battery retainer cover can be effortlessly removed and reinstalled an unlimited number of times without the plastic becoming distorted in any way. This feature makes it easy to remove and replace the cover, which contributes to the cover's overall ease of use and makes it easier to remove the cover.
It was determined how reliable cell holders are by putting them through their paces.
As part of the reliability testing for the BHSD-2032-SM holder base, a swept sine vibration is applied along each of the orthogonal axes for a duration of one hour. The frequency of the vibration is 10-50-10 hertz (Hz). During this time period, there must not be any dislodging of the cells at the base of the holder, nor should there be a break in the continuity of the contact that lasts for more than ten microseconds (ms). As a result of this test, which includes a total of 18 shock pulses as well as three shocks in each direction along each axis, there is no indication that the devices have suffered any kind of physical damage. There were three shocks in each direction along each axis. During the final phase of the mechanical environmental test, the device will be dropped from a height of one meter while being monitored to ensure that the battery cell does not become dislodged.
Users are confident in the dependability of the coin cell holders that Snap Dragon supplies because each holder is subjected to the same stringent testing protocols.
