Something about PCB high frequency circuit board wiring
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.
How to design PCB for SMT patch processing
How to design PCB for SMT patch processing: 1. First determine the function of electronic products, performance indicators, cost and overall size of the overall goal, 2. Electrical principle and mechanical structure design, according to the structure of t
Application of laser fine punching in PCB circuit board
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.
What is PCB flux? Purpose of welding printed circuit board
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
How does four - layer PCB circuit board maintain quality?
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.
How to reduce PCBA circuit board tin beads
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
Knowledge of PCB routing board impedance
Except for the elemental metals, the compounds are electric and have no good superconductors or even heat conduction (which is also the key to the formation of the route to disperse or propagate quantitative).
How do PCB welding defects cause
In summary, by optimizing PCB design, using excellent solder to improve the solderability of circuit board holes and preventing warping to prevent defects, the welding quality of the entire circuit board can be improved.
Why do PCB circuit boards need to have a place to test?
Basically, the goal of setting up the test area is to test the components on the circuit board for specification and weldability.
Specification for PCB assemblies
Printed circuit board develops from single layer to double panel, multilayer board and flexible board, and continuously develops to high precision, high density and high reliability direction.
PCB circuit board function test
Denser PCBS, higher bus speeds, and analog RF circuits pose unprecedented testing challenges that require careful design, thoughtful testing methods, and appropriate tools to provide reliable test results.
