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 […]

For PCB repair functions, given a large enough production lot or a long field life, a board will inevitably need maintenance. Rework before field usage is also critical, and some amount during manufacturing is always expected. In either case, technicians should be also to identify some of the common modes of failure for PCBs to
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
In electronics manufacturing, printed circuit boards are separated into three categories: 1, 2 and 3. The categories reflect the level of quality of each circuit board type, from lowest (Class 1 standards) to highest (Class 3 standards). This classification system was developed and is monitored by IPC under the IPC-6011 standard. Perhaps the major difference

In the layout of printed circuit boards, width plays an important part, especially in the metal connections fabricated into the board called “traces”. Traces conduct signals to and from the pins of the components soldered to the board and carry varying amounts of current depending on the net. Additionally, the signal’s traces may have special
Consumers are becoming more aware of the long-term implications of their purchases. Waste is a serious problem, and efforts to reduce environmental impact play a key role in how many products are sold. While this is more of a “feel- good” method by which end-users can attempt to lower their carbon footprint, industries will often
As electronic technology witnessed significant development in the last few years, the demand and need for high Tg PCBs (Tg =Glass Transition Temperature) have increased. Tg is considered the most important feature of any epoxy product. Tg is the temperature where any solid or rigid product is changed into a rubbery state that greatly altera
Electrostatic discharge (ESD) occurs when any charged body attempts to become electrically neutral. During ESD, the static charges stored in one body rapidly get transferred to another at different electrical potentials through direct physical contact, induction, or arcing. ESD generates voltage that can damage electronic components. Electronic parts that are sensitive to ESD voltage are

This article will summarize the differences between the integrated circuit (IC) and printed circuit board (PCB). 1 PCB Basics 1.1 Composition of PCB -Wiring the Pattern: the wiring is a tool to conduct the components, and a large copper surface is additionally designed to ground and used as the power. The wiring and the pattern
Modern PCB designs are expected to be high speed, multi-functioning, and have tight board space utilization. And, PCB materials must be of high quality, resistant to temperature variations, and easy to handle. One widely-used type of PCB dielectric material that exhibits many of these desirable qualities is FR4 material. In this article, we will discuss
