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.
Tin (Sn) based solder is still the best material for PCB assembly in the modern industry today. The only difference is the lead (Pb) free from the solder base due to environmental concerns. The melting point of tin (Sn) as 231.9°C, is hardly accepted by PCB assembly since most electronic components may not sustain such
Wave Soldering VS Reflow Soldering For PCB assembly, the two soldering techniques called wave soldering and reflow soldering are very different in their functional approach to soldering components. For example, wave soldering incorporates the use of wave crests or peaks to solder the components. On the other hand, reflow soldering utilizes an oven to heat
Gradual evolution of printed circuit boards has made PCBs a critical, efficient, and compact component of a wide gamut of automobiles, machines and devices, computing terminals and other electronics. The introduction of PCBs has also contributed to certain technological developments and inventions in the global electronics industry. The ability of PCBs to connect a single
The manufacturing process for printed circuit boards (PCBs) usually includes a procedure known as reflow soldering, or reflow. Reflow involves covering the surface of the PCB with solder paste to facilitate temporary attachment of the board’s thousands of minuscule components to their PCB pads. The solder paste stabilizes the components long enough for an application
A PCB assembly process requires collective and sustained attention to ensure the end product’s quality. In the absence of a solid PCB assembly defect detection system, you may miss a tilted component or a bad solder web despite rigorous manual testing. If you are lucky, it may only cost you some additional reworks. Worst case
Are you dealing with voids in your solder joints and wondering how to avoid this in the future? Learn more about why voids are created and exactly how to precent this phenomenon form occurring. What is voiding? Solder joint voids refer to empty spaces that occur within a joint. Solder voids typically contain air and
If your project requirements have led you into considering a double-sided PCB design, it is important to understand the assembly process, the pros and cons, and other items you may want to look out for while putting together your design. Pros: Why Go Double-Sided PCB Most PCBs that are designed and built are single sided.
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
As we all know, an incorrect component placement during PCB assembly can create problems for the completed circuit board ranging from performance to manufacturability. Because these SMT placement issues can manifest themselves in vastly different ways, we will generalize them in the following eight categories: 1. Signal integrity SMT components that are not placed correctly
