Influence PCB circuit board "processing price" what are the factors of change
The cost calculation of PCB industry is the most special and complex in all industries. From opening, platen, forming, to FQC, packaging, completion and warehousing.
What are the quality factors affecting PCB circuit board?
in fact, repair maintenance cost greatly increased at the same time, customer brand affected, It doesn't pay off in the long run.
Explain the storage and shelf life of PCB circuit boards
the temperature reproducibility can be obtained through multiple tests, so as to systematically evaluate the performance of the press.
Teach you how to test PCB circuit board is qualified
Electrical testing is a very important link in the PCB board manufacturing process, the purpose is to check whether the PCB board is open and short circuit problem, to ensure that the finished products in line with the customer's electrical performanc
Section friends teach you the heat dissipation skills of PCB circuit board
For electronic equipment, a certain amount of heat will be generated during work, so that the internal temperature of the equipment will rise rapidly.
The importance of electroplating to PCB circuit board production
In this process, all surface areas and boreholes are plated with copper, some resistance is poured on the surface of the unwanted copper, and then etching resistance metal is plated.
Update iteration depth of 5 major PCB substrates
The performance, quality, processability, manufacturing level, manufacturing cost and long-term reliability and stability of PCB depend largely on the copper clad plate material.
PCBA processing aluminum substrate manual soldering wire precautions
PCBA processing of aluminum substrate manual soldering wire points for attention: first, pay attention to the welding temperature, two, select the appropriate raw materials, three, with the iron head is harmful to spot welding force
Electromagnetic compatibility in PCB design
When the field strength of electromagnetic field exceeds a certain limit and the operation time is long enough, it may endanger human health. It can also interfere with other electronic devices and communications. All of these need to be protected.
PCB circuit board fault detection method
PCB circuit board fault detection methods: 1, determine the fault location, 2, detection equipment, 3, visual and physical detection, 4, special detection components, 5, on the circuit board for detection, 6, low voltage measurement
Why does the PCB board have to be impedance?
Impedance is usually denoted by z, z is a complex number, the real part is called resistance, the imaginary part is called reactance, and the unit of impedance is ohm.
