Misconceptions in PCB Design

• Importance of Datasheets

  It is crucial to obtain and review datasheets for all devices when designing PCBs. Understanding graphs and parameters, like the V-I characteristic curve of a diode, is essential for confirming the device’s operating point in the circuit.

• Significance of Maintainability

  Considering maintainability in electronic product design is vital for long-term profitability. Prioritizing maintenance can help reduce costs and increase overall profit by avoiding expensive repairs in the future.

• Process Control in PCB Manufacturing

  Poor process control affects the entire value chain in PCB manufacturing. It’s not just about skilled craftsmen but involves aligning design and manufacturing processes to maintain key device indicators and minimize failures during assembly and maintenance.

• Understanding MTBF and Single Machine Failure Rate

  MTBF values and single machine failure rates differ in scale and scope. Customers should not assume that a high MTBF value guarantees flawless operation, as individual machine failure rates can vary significantly.

• Comprehensive Approach to Reliability

  While testing is important, it should be part of a broader reliability strategy. Engineering calculations, specification reviews, simulations, and electronic tests are necessary for ensuring reliability. Temperature tests alone may not predict performance accurately.
