Copper Wrap Plating in PCB Manufacturing

In today's ever-changing world of electronics, reliability has emerged as an essential factor for consumer satisfaction as well as efficiency. Whether it is an LCD monitor working perfectly after five years or it is aerospace technology, it has to be reliable, meaning it has to withstand the test of time. At PCBX, we realize how important it is to integrate cutting-edge manufacturing processes, such as copper wrap plating, into printed circuit boards to ensure longer life and efficiency.

The Imperative of Robust Plating in PCBs

PCBs are basically the hub of all electronic products performing the role of nerve pathways, transmitting signals between each other so as to make the component function. One of the critical elements in the manufacture of these pathways is the plating process employed so as to improve the component’s endurance against mechanical and thermal stresses. Copper Wrap Plating is a new technology that adheres to the standards of IPC 6012E and focuses on improving the reliability of vias-in-pad solutions.

Copper Wrap Plating Process

Copper wrap plating helps to enhance the overall strength of PCBs. This process ensures that there is no gap in the electrical connection between the via hole and the overlay traces. This technique of copper plating helps to cover the outer edge of the via as well as the annular ring surrounding the via pad in addition to encasing the edge of the via.

In copper wrap plating, two major structural techniques are:

Through-Pad and Trace Formation: By coating the inside wall of the through-hole and coppering over the top and bottom layers at the ends of the vias, this configuration forms a good electrical connection through layers in a PCB. An electrical connection is important for signal integrity in layers, as it relates to multi-layer PCBs.

Butt Joint Construction: In this type both pads develop a distinct layer around the ends of the through-hole, which will connect to traces or grounds. While it’s still a non-fully connected joint, the copper layer does add strength to the interface to withstand temperatures.

Addressing Thermal Cycling Challenges

Thermal cycling is an inevitability in PCBs, which occurs during power cycles. The expansion and contraction of the PCB will subject the copper plating to tensile stress. When the PCTs of the materials used in a PCB do not match exactly, added stress caused by the difference is accumulated, resulting in potential breaks. The copper wrap plating process eliminates this issue by adding copper layers.

Further enhancing the robustness of the circuit board, it is also possible to apply cap plating on the wrap plating and add layers on the through-hole top and bottom. Apart from this, this method of circuit board manufacturing is adaptable enough and can be used even on buried vias, making it flexible and adaptable. Additionally, it is able to adhere to the IPC-A-600 standards.

Integrating Multilayer PCBs and Copper Wrap Plating

PCBs with multiple layers have become a need with the ever-increasing push towards mini yet power-packed electronics. These PCBs are able to cater to strict requirements of size and lightness that are necessary requirements of contemporary electronics products. Copper wrap plating is an important part of helping such PCBs become robust and encourage smooth electrical and thermatic flux between layers with their use of effective through-hole connections.

Vias—through hole vias, blind vias, and buried vias—play critical roles in interfacing layers on a PCB. All three require and benefit from the reinforcement provided by copper wrap plating. As a means of providing connectivity between layers or between outer and inner layers and their respective coatings, copper wrap plating ensures that vias are adequately sturdy.
