Cause Analysis of Copper Wire Shedding from PCB

Reason 1. Copper foil shedding of PCB due to process factors of PCB manufacturer, Reason 2. Copper foil shedding from PCB due to customer’s PCB design factors, Reason 3. Copper foil shedding of PCB due to PCB material?.

Development of copper foil technology for PCB circuit board

Copper foil production was started in 1937 at the Anaconda Copper Refinery in the United States. The copper foil was then used only for waterproof purposes on wooden roofs.

Classification of CEM-3 and FR-4 PCB Multilayer Material

A1 level multi-layer PCB material quality of this series of products has completely reached the world-class level, which is the highest grade and best performance product of FR-4 PCB.

Application of copper coating and nickel plating on PCB board

The coating of PCB boards varies according to the use of the boards. Here is a brief description of the properties and uses of copper and nickel coatings from the circuit board manufacturer IPCB.

Surface treatment and wet process for PCB manufacturing

Abrasives are the materials used to grind and brush the copper surface before cleaning the PCB surface, such as polymer nonwoven or nonwoven cloth with diamond sand.
