Ampoule laser drilling is the process of drilling holes of varying sizes into glass, which can produce holes of varying sizes and shapes. It can also create through holes, which is ideal for developing certain specific projects such as CCIT, container closure integrity test positive samples, or cooling vents. Other holes may be smaller but have a rough surface.

Ampoule laser drilling uses a laser beam when drilling, and by precisely controlling the beam and setting the desired output, the desired hole size is achieved.

Working principle of ampoule laser drilling

Laser beam is a unique method of drilling holes through heat treatment technology. When using high energy depth, the user focuses the ampoule material on an intense beam, which causes melting and vaporization of the material.

Thus, the steam pressure will trigger the particles to come out of the drilled hole. Pulsed laser can be used to obtain the desired results and depth. The process will be completed smoothly due to the following factors.

Material Strength

Opening diameter

Processing speed

Drilling holes smaller than 0.25mm is always challenging, so laser drilling is required to drill accurately.

Laser drilling of ampoules is a process that works well under automated conditions. When drilling, the following parameters should be displayed:

wavelength

Laser beam quality

Pulse duration

Strength

Pulse repetition rate

You will also need simulation and modeling. This way, the process will be more predictable and precise. Interestingly, laser drilling has proven to be a less expensive method compared to other outdated methods such as mechanical drilling.

It is a perfect alternative to stamping, CNC and EDM by performing micro-hole drilling. These methods happen to be destructive during the drilling process. Laser drilling is useful in the manufacturing industry.

By controlling the laser power, you can drill holes of various sizes, and also allow for rapid prototyping to create a specific range of different hole sizes.

Laser drilling methods are often dynamic. You can also use it to change the hole diameter, edge quality and hole depth.

What is admirable about laser drilling is that the hole has a taper. In other definitions, the hole may not have to be straight. Also, the hole may be redeposited because you will make the hole through a drastic phase change. Especially in CCIT positive sample preparation, it can make the leak hole as close to the real leak hole as possible.

Advantages of Laser Drilling

It is a non-contact technique. The type of drilling medium involves light. In other definitions, no physical contact is required between the workpiece and the moving parts. It does not wear out the drilling parts and does not contaminate the workpiece.

One can create high aspect ratios. You can easily make a small hole with an aspect ratio of 30:1.

Laser drilling is a method of machining holes in materials without damaging them. They may range from metal to rock, wood and rubber.

The laser drilling process can accomplish multiple tasks.
