Misunderstanding 6: The device is very simple, so whether there is a datasheet is not important.
When designing, it is crucial to obtain the datasheet for all devices, and carefully review all graphs and parameters. Establishing a connection with these curves in the design process is essential. For example, the V-I characteristic curve of a diode should be thoroughly examined to confirm the static operating point of the device in the circuit design.
Misunderstanding 7: Maintainability is not my concern.
The goal of electronic product reliability work is to generate profit. Profit is achieved by increasing revenue and cutting costs. While it may be tempting to save on material costs, this can lead to higher maintenance expenses. The key is to prioritize maintainability and save on these costs, resulting in genuine profit.
Misunderstanding 8: Poor process control reflects a lack of skilled craftsmen.
Poor process control is not solely a craftsman’s issue; it involves the entire value chain. From design engineer’s requirements for the device to purchasing engineer’s selection of manufacturers and control of inspection processes, every step must focus on maintaining key device indicators, avoiding failure mechanisms, and minimizing damage during assembly and maintenance. Consistency can be achieved by providing design engineers with sufficient technical information and ensuring manufacturing reliability aligns closely with design reliability.
Misunderstanding 9: Understanding the relationship between MTBF value and single machine failure rate.
MTBF is a macroscopic, statistical concept, while single machine failure is a specific, microscopic concept. Customers often wrongly assume that a product with a MTBF value of 10,000 hours guarantees trouble-free operation for that duration. This misconception overlooks the complexity and variability of failure rates for individual machines.
Misunderstanding 10: Relying on testing to solve reliability issues.
While testing is an important aspect of ensuring reliability, it is not a standalone solution. Some problems cannot be detected through simulation tests alone, and a comprehensive approach combining engineering calculations, specification reviews, simulations, and electronic simulations is necessary. Additionally, the results of temperature enhancement tests may not accurately predict low temperature performance.
