Why does PCB board bubble?
PCB board surface bubbling may be the problem of poor binding force on the board surface, and then extension is the surface quality of the board.

Crystal vibration is the reason for PCB design?
The crystal vibration does not vibrate during product debugging, which may be due to the crystal vibration device itself or PCB design.
The cause of PCB circuit board bubbles have those?
Board bubbling is one of the most common quality defects in PCB production. Because of the complexity of PCB production process and process maintenance, especially in chemical wet treatment, it is difficult to prevent board bubbling defects.
The accuracy of Dk test methods is affected by many factors
As the frequency of circuits and applications increases, a number of different methods have been developed for determining basic parameters such as material Dk and loss factor (Df).
Cause of copper cable loss of PCB circuit board
The abnormal quality of PCB board will cause direct losses to customers and PCB manufacturers. The loss of copper wire is one of the abnormal quality phenomena, but this kind of abnormal will cause greater losses to PCB manufacturers.
Photoresist etching on PCB designs
Large PCB manufacturers use electroplating and etching processes to produce wiring on the board. For electroplating, the production process begins with the plating of copper over the outer plate substrate.PCB manufacturers
Hefei hybrid circuit PCB design quotation
there are a few things you should be aware of. Let's take a closer look at what a pad through-hole (VIP) design is and how it can help you when laying out printed circuit boards.
How is the chip welded to the circuit board?
The chips are welded to the circuit board by soldering, and the circuit board is "wired" to establish the electrical connection between the chips.
Hefei multi-layer PCB design and development scheme
When using power rails, high voltage components, and other heat sensitive parts of the board, the PCB line width in relation to the ammeter can be used to determine the line width to use in the layout.
Hefei simple PCB design wiring
PCB designers should minimize the number of bypass capacitors, which can increase current loss. Hefei simple PCB design wiring
Overview of PCBA electrical stress test methods
Some basic testing and inspection tasks may be required to be performed on your PCB/PCBA during the manufacturing and assembly process, and it is recommended that these tests be performed, at the very least, to ensure continuity, accurate assembly, and si
Overview of PCBA electrical stress test methods
Quality control in mass production and prototyping has a common set of important tasks: the need for PCB testing. The specific set of tests you need to perform in a PCBA depends on its application area, desired service conditions, and, of course, the rele
