What is a copper-based circuit board?
There are positive and negative sides, the white side is welded LED pin, the other side shows aluminum color, generally coated with thermal coagulation and thermal part contact. Ceramic substrate and so on.

High-density interconnected Circuit Board (HDI)
The best stacking mode, because the use of multi-layer ground reference plane has very good geomagnetic absorption capacity.
PCB circuit board cooling skills
the thermal performance index analysis software module added in some professional PCB design software can help designers optimize circuit design.
Detail PCB circuit board high frequency board and high speed board difference!
there are still some differences between high frequency products and high speed products in the demand for plate.
HDI board
At present, the use of polyphenyl ether (PPO or PPE) resin is a good development direction, whether from high frequency materials or high speed materials.
How to heat circuit boards
In the design of the power resistance as far as possible to select some large components, and adjust the layout of the printed circuit board so that it has enough space for heat dissipation.
Dongguan Chang 'an circuit board processing
Peel off the bad part of the copper wire to see the copper foil surface, you can see the normal color of the copper foil surface, there will be no bad side erosion, copper foil peeling strength is normal.
Shanghai circuit board processing
In the process of board making, there are several processes to go through the yellow light room. The visual effect of green in the yellow light room is better, but this is not the main.
Rf circuit board machining
The flow rate of the glass discharge tube should be greater than the flow capacity of the lightning protection circuit design.
The influence of wrinkle on circuit board machining
resulting in positioning (only for the large plate) or sporadic copper wire loss, but the stripping strength of copper foil near the stripping line will not be abnormal.
Four reasons for PCB board copper throwing
it will also lead to insufficient bonding force between copper foil and substrate after laminate, resulting in positioning (only for the large plate) or sporadic copper wire loss, but the stripping strength of copper foil near the stripping line will not
Circuit board plus process edge + purpose
Using the principle of electroplating, through the current and voltage control of gold plating on the surface. Anti-oxidation: The use of chemical principles of an anti-oxidation chemical coated on the surface
