When customers purchase an insertion force tester, they often assume it's only used for measuring insertion force. However, the capabilities of the milligram instrument go far beyond basic insertion and extraction force testing. Here’s a detailed overview of its extended functions:
1. The insertion force tester is capable of performing insertion force tests, separation force tests, and plug life tests—functions that are widely available among other suppliers. However, not all devices offer consistent accuracy. Some may suffer from stroke drift, fewer sampling points, or falsified speed settings. These issues can affect the reliability of test results.
2. For connectors like SIM card slots or battery contacts, the most common test is the longitudinal force test. This typically requires a 5kg or 2kg sensor to measure the load at a specific height. Some customers even require the load measurement at the bottom of the plastic housing. Proper setup involves calibrating the zero position each time, which requires both software support and operational skill. While some suppliers can perform this, their software may lack user-friendliness.
3. Many computer and mobile phone manufacturers use buttons in their products, and the milligram instrument is capable of testing button peak and valley forces—commonly known as switch load-displacement tests. It uses a 50kg sensor to detect minute differences, such as just 2 grams of force. Most other vendors don’t offer this level of precision. If you’re specifically testing buttons, we recommend our patented S05 load-displacement meter.
4. The milligram instrument also supports constant tensile testing, known as a hoisting test in national standards. This function applies a set force over a specified period, ensuring consistent performance. Other suppliers rarely include this feature, and when they do, it's often less refined in terms of accuracy and protection settings.
5. Additionally, the milligram instrument can perform breakage and fracture tests, replacing some functions of a tensile testing machine. It can also conduct peeling force tests (with custom procedures), as well as retention and contact resistance tests—though these are less commonly requested.
The milligram instrument’s advanced features make it stand out in the market. While it may cost more than similar devices, its enhanced functionality and reliability justify the investment. When purchasing equipment, it's essential to consider not just the price but also practicality and long-term value.
