it is best to check whether the power supply of the equipment is correctly supplied to the circuit board as required, and whether the interface plug-ins on the circuit board are connected.
High frequency circuit board is a special kind of circuit board with high electromagnetic frequency. Generally speaking, high frequency can be defined as frequency above 1GHz.
In the future market development, circuit board maintenance technology has been accepted by more and more people. Therefore, it also promotes the development of circuit board maintenance industry.
This paper introduces a new maintenance tool, on-line tester, and focuses on the function characteristics of the tester and the methods and steps of using it to repair the circuit board.
The lead inductance of patch resistors and capacitors is greatly reduced, which has great advantages in high frequency circuits. The disadvantage of surface mounted components is that they are not easily welded by hand.
The fabrication of microholes on the circuit board and the molding of the circuit board as the hot spot of laser processing have created a sensation in the world, laser processing with its superiority has brought huge benefits.
The use of PCB solder solder has become so common that it is most unusual to see that there is no solder for any PCB to resist covering, except for some home built circuits today, and even many prototype boards have solder solder
Usually does not contain volatile solvent, low temperature fast curing, can meet the requirements of mass production automation, high production efficiency, good product quality, heat resistant curing flux accounts for more than ten energy.
Other features are also available, including crimping pins, graphic overlays, laser cut grooves, carved flexible circuits, shields, flexible heaters and stiffeners. With so many possibilities, there is a flexible circuit board to suit every need.
The layout and wiring of the meta parts is a very flexible office. The layout and wiring of the meta parts are not unique. The final result of the layout and wiring depends very much on the experience of the person who assumes the position of the PCB.
Measures to reduce the tin residue of PCBA tin beads: 1, attach importance to the production of steel mesh, combined with the specific component layout of PCBA board, appropriately adjust the size of the opening, so as to control the printing amount, 2, b
This makes it possible to get a prototype in a matter of days, ship a fully assembled product directly to the customer, and offer a price within minutes. As more innovative products and higher quality products enter the market with fewer barriers to creat
