PCB circuit boards will produce some bad problems in the overheating temperature, so for different materials of PCB circuit boards, the temperature resistance, need to be understood in detail, do not exceed its high limit temperature, so as to avoid the P
Ink is gelatinous when standing, and is touched when the viscosity changes a property, also known as shaking, anti flow hanging
As long as the circuit board has detected the problem, then maintenance is easy. The following is a summary of the circuit board maintenance basic formula, convenient and practical.
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: 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
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
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
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).
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.
Basically, the goal of setting up the test area is to test the components on the circuit board for specification and weldability.
