1. Single-Side Copper PCB For E Bike Electronic Board is a small green chip covered with lines and copper parts that you can find at the heart of the electronics. It is made of fiberglass, copper wire and other metal parts, fixed together with epoxy resin and insulated with a solder mask. Its substrate is the base material in its manufacture, which gives the PCB rigidity. A thin layer of conductive copper foil is added to each functional side of it.
2. The top of Single-Side Copper PCB For E Bike Electronic Board's copper layer is a solder mask that provides each PCB with its characteristic green color. It insulates the copper trace from unintentional contact with other conductive materials. The holes in the solder mask are where solder is applied to attach the component to the board. The solder mask is a critical step in the smooth fabrication of PCBA because it avoids soldering on unwanted components and avoids short circuits.
3. Single-Side Copper PCB For E Bike Electronic Board's white screen printing is the last layer on the PCB. This layer adds labels to the PCB in the form of characters and symbols. This helps to indicate the function of each component on the board. These materials and components remain essentially the same on all PCBs except the substrate. The substrate material of the PCB varies according to the specific quality that each designer is looking for in their finished product.
