The standard solder mask formulation used in modern PCBs is a polymer material that is cured and hardened during bare-board fabrication. The solder mask used in a PCB is an important tool that helps protect conductors on surface layers and it aids assembly of the bare board. But just like other materials used to build
The use of multilayer PCBs has become ubiquitous with several industries employing complex PCBs in increasingly miniaturized products. There are many factors, however, that determine the cost of a multilayer PCBs. Here is a quick overview: Choice of material The material used to fabricate the board has an obvious bearing
When it comes to prototyping your PCB board, choosing the right material is crucial. The material you select will impact the performance, cost, and durability of your final product. With so many options available, it can be challenging to determine which material is best for your PCB board. In this article, we’ll provide a comprehensive
The success of PCB manufacturing lies on the reliability and consistency of the process. To achieve this, strict tolerances must be maintained throughout the manufacturing process. In the world of PCB fabrication, tolerance refers to the amount of allowable deviation from a specified value. For example, a PCB trace width might have a tolerance of
PCBs are an integral component of any electronic device whether it is a small toy or a sophisticated machine. Its complex interconnected components comprising of resistors, diodes, capacitors, sensors, ICs, and more complicated parts allow the device to work together. In a sense, it is like the brain of the system. Therefore, it is critical
In the world of printed circuit boards (PCBs), designers are always seeking ways to create efficient, reliable, and cost-effective products. One of the critical decisions in PCB design is the choice between aluminum PCBs and copper PCBs. Both have their advantages and disadvantages, and the right choice depends on the specific application and requirements of
The PCB industry has witnessed several changes over the years and one such was the transition from rigid to flexible circuit boards. For several years, engineers used to create flex circuit boards by connecting multiple small rigid boards with cables. This is because flex circuit board fabrication was a tedious process and quite expensive, too.
Key Takeaways ●Gain a greater understanding of the FMEA process. ●Develop a greater understanding of the FTA process. ●Understand how to discern which process best fits your company’s needs. Understand failure mode and effects analysis (FMEA) vs. fault tree analysis (FTA) to choose the right method for your company. Whether you work in the field
Using vias in a PCB design allows the designer to shorten the distance that a trace must be routed in order to complete its connection. Vias are metallic lined holes connected to the metal circuitry of a PCB that conduct an electrical signal between the different layers of the board. Although vias can vary
Deciding on the best testing method for your printed circuit board can be a daunting task. There are plenty of factors to take into consideration, including costs, coverage, and development lead time. However, there are two popular test strategies you’ll often find yourself choosing between: ICT testing vs flying probe testing.
