Although every new circuit board design your company creates is unique, reproducibility is one of the most important attributes your PCBA manufacturing process can possess. Unfortunately, achieving this goal is most challenging when opportunities for human error exist. It is important to know the pros and cons of automation in manufacturing and how well your
Even if you’ve never fabricated a PCB, you might be familiar with the process. PCB etching involves the application of UV-resistant laminate to a presensitized photoresist copper layer, which is then exposed to UV rays. Areas that are not covered will be etched off in a special etching solution. The PCB minimum etch technique has
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
Electronics manufacturers incorporate dielectric materials in components and devices to provide insulation, electrical storage, or current flow resistance. PCB material companies leverage these characteristics to construct board substrates and laminates. During PCBA development, engineers, board developers, and CMs seek the optimal arrangement of dielectric materials to maximize signal integrity or the fidelity of signal propagation
After the PCB board layout design is completed, it is necessary to carefully check whether the wiring design meets the rules set by the designer, and also to confirm whether the established rules meet the requirements of the PCB board production process. After the general PCB board layout design is completed, you need to check
Documenting your entire design process may seem tedious or inconvenient at times, but it ends up being a critical piece of creating a great product. PCB design is no exception, so designers need to be aware of documenting the right information, in the right way, to successfully manufacture their final product. Not sure where to
Almost all electronics devices in use today have printed circuit boards (PCBs) embedded within, which work like their nucleus. PCBs are crucial to the point where they contribute to their performance and functionality, and hence they must be flawless. As part of this, the material to make the PCBs must be chosen carefully depending on
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
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
