Differences between software and hardware solutions for mobile power in Namisoft testing [Copy link]

Having been engaged in IC R&D and sales in the mobile power industry for many years, customers often ask: How to choose a mobile power test solution to avoid many problems while having high performance and low-cost testing ? Here I would like to share with you how to choose amobile power

The two main points of Namisoft's mobile power products are function and performance. Before choosing a solution, we must first consider safety and efficiency as the first factor . Then we can choose the test items. If the safety of mobile power test is not guaranteed, no matter how cool your software system is, how efficient it is in theory , and how beautiful the interface is, it is not a mobile power automatic test system worth using .

　　Safety - A safe mobile power supply is one that has protection against overcharge, over discharge, short circuit, over current, current limiting, over voltage, low temperature rise, and at least double protection at the front and back . At present, there are a lot of mixed solutions in the mobile power supply market. In order to achieve the lowest cost, most manufacturers directly skip the secondary protection ( also known as lithium battery protection ) circuit in the low-end test solutions. This solution is mainly used by some assembly-type customers in the electronics market . The NSAT-9000 series solution master control not only has more than 11 protection function test items such as overcharge, over discharge, short circuit, over current, current limiting, over voltage, low temperature rise, low power consumption, and at least double protection at the front and back , but also recommends that manufacturers use the secondary protection when designing PCBs .

Practical applications in circuit boards

Function : Currently, the market is flooded with mobile phones with various functions, such as those with digital tube displays, LCD displays, wireless charging functions, solar charging, etc.

Performance : In addition to safety functions, the performance of mobile power supplies is also one of the most important indicators. The main measure of performance is efficiency. In terms of improving efficiency, Namisoft has always been at the forefront of the industry in the automated testing of mobile power supplies , providing manufacturers with the same high-efficiency and low-cost automated testing solutions for power supplies / batteries .

Consistency and stability - Many friends have complained to me: When they first chose a certain solution, they felt that its consistency was good, but they found that the consistency and stability were not good during mass production. What's worse, there are often problems of batch returns due to customer complaints after the whole machine is shipped. In fact, this is very related to the entire main control. In order to ship quickly and have a market share, most pure hardware solutions have conducted more detailed consistency tests on their main control chips during the first batch of production, and separated some products with poor performance and stability first. However, when they used low prices to seize the market, they found that if they continued to do so, they would not have the profit space to operate and production capacity, which made them unable to do more sorting tests, resulting in them having no way to control the consistency problem in the process ; in this regard, Namisoft is responsible for market demand planning, preparing stocks in advance, and ensuring the consistency of each chip in the packaging test, and will retest the products with good consistency again, so as to ensure that every chip delivered to the client is perfectly consistent .
