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.
Detail the cause of multilayer circuit board electroplating on nickel gold tin plate?
with the increase of labor cost and raw material price again and again, many customers began to require product price reduction to save costs.
How to make a good PCB board?
In short, the technological parameters and conditions of copper plating must be strictly controlled to ensure that the thickness of the copper plating layer in the hole meets the requirements of the technical standard.
Why does tin-spraying lead to uneven pad surface?
When entering the tin furnace, the liquid tin on the solder plate will be arc shaped by the surface tension of the liquid, resulting in uneven tin thickness on the solder plate.
Circuit board factory: Which kinds of rigid circuit boards are classified
The common multilayer board is generally 4 or 6 layers, complexMultilayer board can reach dozens of layers.
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。
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.
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
The difference between the hole cover oil and the hole window
Reflect the problem, so that you can design engineers do a reference, improve the quality of design and reduce the occurrence of problems!
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.
EMC problem What are the factors in PCB design?
Factors related to EMC issues in PCB design: 1. System design: 2. Structural impact: 3. Cable influence: 4. Component selection: 5. Related to SI/PI simulation: 6. Grounding, 7.PCB design relationship, 8. Software anti-jamming technology: 9. Shielding: 10
