What are the characteristics of PCB circuit boards that are widely used?
he system speed can be greatly reduced because of the increase of delay time caused by the delay of 2ns per 30cm line length of the common interconnect on the baseboard. Image shift register synchronization counter.
Circuit board tips: How to strengthen PCB circuit board BGA prevent cracking
The deformation of the circuit board (PCBA board) usually comes from the rapid temperature rise and rapid temperature drop (thermal expansion and cold contraction) caused by Reflow。
PCB circuit board manufacturer - It is important to solve the plug hole
usually in the process of high-speed PCB design, the seemingly simple holes usually bring great negative effects to the circuit design.
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.
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
The hole cover oil of PCB circuit board and the hole open the window, silly can not be clearly separated?
