The surface-mount IC packages that are assembled on a PCB are available in different types. The most popular ones among these are the QFN packages. These miniature packages are suitable for consumer, industrial, automotive, and power applications. When it comes to...
After PCB fabrication, the copper traces on the board typically face the risk of oxidation and corrosion due to environmental exposure. The most reliable way to prevent this and increase the life of the PCB is to provide a protective coating known as a solder mask...
A critical part of PCB manufacturing is to protect the board from adverse environmental conditions by using various treatments and coatings. A conformal coating is one such process that involves applying a thin, polymeric and non-conductive film “conforming” to the...
In circuit board manufacturing, the process of implementing the PCB surface finish is critical in enhancing the reliability and shelf life of the PCBA. We will cover the various types of surface finishes the printed circuit boards are given to enhance good...
Cost control steps should be taken in the early PCB production stages, including the actual circuit development stage. Be aware of the process steps and cost drivers for rigid circuit boards because each process consumes additional cost in terms of process time,...
What can be more problematic than seeing your expensive PCB not performing as intended? What would you do if your expensive circuit board failed in the production line even after accurate prototyping and thorough testing? One of the common reasons for PCB failure is...
In the era of miniaturization and HDI PCBs, space optimization on the PCB might frequently affect proper component placement. Appropriate component placement on a PCB improves the signal quality and performance of the device. From a PCB assembly point of view, proper...
Rigid-flex PCB designs may be expensive to fabricate, but they can essentially save costs during electronic system assembly. A straight line is not always the shortest route between two points in electronic products: Thanks to rigid-flex PCB architecture, circuits can...
The cross-section or micro-section analysis is a destructive analysis that measures the quality of the manufactured board. It’s basically an interconnection defect analysis process that detects and verifies what went wrong inside the PCB. This is an integral part of...
