Copper base board and aluminum base board difference | YMSPCB

Copper base board and aluminum base board difference 1. The thermal conductivity of copper base board is twice that of aluminum base board. The higher the thermal conductivity is, the higher the thermal conductivity is, and the better the heat dissipation function is. 2. Copper base board can be ... Read More

Understand the construction of heavy copper PCB | YMSPCB

Heavy copper PCB is made with 4 or more ounces of copper per layer. 4 oz copper PCB is most commonly used in commercial products. Copper concentrations can be as high as 200 ounces per square foot. Heavy copper PCB is widely used in electronics and circuits requiring high power transmission. In a... Read More

Common reasons for PCB to dump copper | YMSPCB

There are several common reasons for PCB factory to dump copper: I. PCB factory manufacturing process factors: 1. Excessive etching of copper foil, the electrolytic copper foil used in the market is generally single-sided galvanized (commonly known as ash foil) and single-sided copper plating (co... Read More

PCB coated with copper knowledge tips | YMSPCB

Copper coating is a common procedure that covers areas of a printed circuit board that are not wired with copper. This can enhance the anti-interference performance of the printed circuit board. By copper coating, the unused space on the PCB is used as a base level and then filled with solid copp... Read More

9 attention points of copper application | YMSPCB

By copper coating, the unused space on the PCB  is used as the base level and then filled with solid copper, which is also known as copper pouring. The significance of copper coating lies in reducing ground resistance, improving anti-interference ability, reducing voltage drop, improving power ef... Read More

What are the requirements for copper thickness of PCB orifice | YMSPCB

The holes on the printed circuit board are generally divided into those with copper holes and those without copper holes, which are mainly used for positioning and installation, and generally belong to relatively large holes, more than 0.8mm. And the through hole generally belongs to the plug-in ... Read More

PCB hole copper fracture reason | YMSPCB

PCB hole copper Hole copper is the hole with metallization requirements, by electroplating the hole with a layer of copper, so that the two sides of the hole can be conducted, the layer of copper in the hole is called hole copper. PCB hole copper fracture reason 1. Local copper thickness caused b... Read More

PCB copper coating experience

Copper-coating, in which unused space on a PCB is used as a base level and then filled with solid copper, is called copper pouring. The significance of copper coating lies in reducing ground resistance, improving anti-interference ability, reduceing voltage drop, improving power efficiency, conne... Read More
