Most of the equity is controlled by banks and trust shareholders or occupies a large proportion, which is not conducive to stand out in the competition of PCB market in the future.
There are many kinds of surface treatment of the circuit board. PCB proofing personnel should choose according to the performance and requirements of the board.
The use of direct paving mode is characterized by a strong overcurrent capacity of the pad, for high-power circuit device pins must be used in this way. At the same time, its thermal conductivity is also very strong, although the work is good for the heat
Like this kind of treatment method for those engaged in small household appliances PCB Layout friends are not unfamiliar, so if the amount of tin is uniform enough and the amount of tin is enough, this 1mm wire can be seen as more than a 2mm wire.
which also means that the frequency is higher and higher, the requirements of the circuit board substrate is also higher and higher.
When the production of laminate using copper foil and the resin system does not match, resulting in sheet metal foil peeling strength is not enough, plug-in will also appear bad copper wire shedding.
For PCB products in these emerging markets, the process and raw materials of high-end high frequency and high speed pcb board need to be comprehensively upgraded, and the technical barriers are comprehensively improved. The key to realize high frequency o
How to ensure accurate assembly and quality control? First, accurate assembly, second, quality control, third, testing
What are the characteristics of PCBA assembly plants? First, design ability of PCBA assembly plant; second, quality control of PCBA assembly plant; third, technical support of PCBA assembly plant
PCB fabrication is one of the most important steps for PCBA processing plant to complete the task quickly and accurately, including: the process design of the board, tooling design and production, the production of the circuit board
These technical challenges require domestic PCB enterprises to grasp the trend of technology and market at all times and take the road of differentiation in order to build unique competitiveness
With the rapid development of the electronic information industry, PCB industry continues to grow. The global output of PCB increased from more than $40 billion in 2008 to $60 billion in 2018. The share of China's PCB industry in the world has also change
