In order to establish connections through different layers of printed circuit boards, it’s necessary to drill holes through them. One of the most effective ways to accomplish this with remarkable accuracy is laser drilling.
No matter the size of the holes that are necessary, laser drilling ensures that they are created with efficacy and efficiency. Then, traces, pads, and copper polygons can be connected to the top layer, bottom layer, or any layer in between. Continue reading to learn more about the many benefits of laser drilling as they correlate to PCB assembly services.
One of the other prominent methods of drilling – mechanical drilling – requires physical contact with the material. As such, it may induce damage on the material due to vibration. On the other hand, laser drilling is a non-contact process and therefore does not pose a risk of damage due to vibration.
Unparalleled and Precise Accuracy
Laser drilling enables PCB assembly manufacturers to drill holes through circuit boards using beams that are precisely controlled and highly accurate. This is due to the fact that the beam intensity, heat output, and duration can all be controlled at an exact level. Laser drilling reduces errors, which saves you time and budget.
Achieve High Aspect Ratios
Thanks to the precise capabilities of laser drilling, PCB manufacturing companies can produce circuit boards with high aspect ratios. The aspect ratio is the ratio between the depth of the hole and the diameter of the hole. As previously stated, lasers are capable of drilling remarkably narrow holes with great accuracy, which yields a high aspect ratio.
More Than One Use
The benefits of laser drilling aren’t limited to just PCB assembly services. It can also be used in other advanced manufacturing processes, such as welding and cutting, to make precise cuts through materials.
Before using laser drilling for circuit card assembly, it is important to remember that different materials absorb energy at different rates. Therefore, the different elements of a stack-up should be as homogenous as possible. This will promote an equal and accurate drill through the layers of the PCB.
