PCB board repair refers to the bringing the physical damage which has been done to a PCB-namely pad or trace lifting, laminate repair, eyelet replacement to name a few-back to a point to where the printed circuit board can function based on the original design requirements. Printed circuit board repair skills and processes require lots of patience and a high degree of hand-eye coordination.
With the continuous improvement of the working speed of electronic circuit boards and the requirements for higher data transmission rates, the traditional lumped circuit parameter model has also been replaced by distributed circuit parameter models, and circuit boards designers are increasingly shifting their attention. How to overcome various signal integrity problems that occur in high-speed…
Except double layers PCB Board, 4 layers PCB board is also very hot subject in the electronic world, in fact, 4 layers PCB board copying stands for two double-sided boards duplication, and 6 layer PCB board copying means replicate three double-sided PCB boards…. The reason why multiple layers PCB Board copying are daunting is because…
Generally speaking, Reverse Engineering Printed Circuit Board is get the target board scanned and recording the position of each one of the component in detail, then de-soldering components off PCB to make a bill of materials (BOM) and the material procurement. The empty board will be scanned into a high resolution picture and processing…
How to Restore Printed Circuit Board without Schematic Diagram When try to Restore Printed Circuit Board in the absence of its schematic diagram, especially when this Printed Circuit Board is relatively strange to the engineer, according to previous experience, even if a veteran Printed Circuit Board restoring engineer won’t be able to fix this issue…
Multilayer HDI PCB Board is such a large and growing PCB application market that it is made up of at least four different HDI platforms: (1) Substrates and Interposers; (2) Modules; (3) Portables; and (4) High performance. Later we will provide more detail about the HDI market. Substrate and Interposer technology is used for flip-chip or…
The next major advance that made the printed circuit board technology indispensable and laid the foundation for what we see today, was the ability to put a conductive surface inside a hole in a non-conductive material. This revolution has allowed interconnected circuitry on two sides and through many layers, giving rise to the plated through-hole.…
