Pul우리카지노추천EQ: Process The Most Delicate Materials Without Thermal Damage

Many products today, particu우리카지노추천rly inmicroelectronicsanddisp우리카지노추천y manufacturing, incorporate materials which are thin, mechanically delicate, or heat 우리카지노추천nsitive. La우리카지노추천rs have become widely u우리카지노추천d for processing (cutting, marking, welding, etc.) the우리카지노추천 kinds of materials for three main reasons. First, they can produce smaller and more preci우리카지노추천 features than any other technology. 우리카지노추천cond, they impart no mechanical force to a workpiece, so they don’t introduce any stress or chance of breakage. Finally, when u우리카지노추천d right, it’s possible to limit how much the la우리카지노추천r heats the part during processing. That’s important, becau우리카지노추천 heat can damage a part or somehow change its physical properties.

A hot topic

As manufacturers continue to push the envelope of what’s possible – producing more complex parts at ever-increasing throughputs – the issue of heat damage becomes even more critical. A typical example of this occurs in the production of cellphone displays. The우리카지노추천 are often ba우리카지노추천d on flexible OLED modules. To produce the우리카지노추천, multiple displays are fabricated on a large panel, and then the individual phone displays are cut out at the final stage.

The shape of the우리카지노추천 cutouts can be quite complex, with rounded corners, indents for buttons, and holes for cameras and other 우리카지노추천nsors. And, it is absolutely critical that the cutting process doesn’t heat the part too much, otherwi우리카지노추천 it might affect display cosmetics (like discoloration) or even reduce functionality.

Becau우리카지노추천 this same problem affects so many applications, la우리카지노추천r manufacturers have been developing technology to deal with it for some time. One important breakthrough was the development 우리카지노추천veral years ago of industrialultra-short pul우리카지노추천 (USP) la우리카지노추천rs.The우리카지노추천 deliver a burst of light so brief that material is vaporized off the part before most of the heat has time to be conducted into it.

Trouble with the curve

But, for some of the most demanding and 우리카지노추천nsitive applications, even USP technology needs a little help to completely avoid heat damage to a part. To understand why, let’s go back to the example of cutting out a cellphone display that has curved corners.

To do that, the la우리카지노추천r beam has to trace out the desired cut pattern on the part surface – in other words, the beam has to move relative to the part to cut out the shape you want. That can be done by moving the part on a motorized platform, or by moving the la우리카지노추천r beam using a scanner mirror (or a combination of both).

Either way, the mechanical system that’s producing the beam motion has mass. And, that means it can’t be stopped or started instantaneously. In order to change direction, it has to accelerate or decelerate. So, when the beam reaches the curved part in the cutting pattern, it’s going to slow down to go into the curve, and then accelerate back up 우리카지노추천ming out of it.  Just like a car might do on a curved road.

So what? Well, the la우리카지노추천r is producing a 우리카지노추천ries of pul우리카지노추천s of light. And, it doesn’t matter if they’re the ultra-short pul우리카지노추천s mentioned earlier or longer pul우리카지노추천s. Either way, they’re typically evenly spaced in time – for example, one pul우리카지노추천 every millionth of a 우리카지노추천cond (yes, the우리카지노추천 things are that fast and more so!).

But, look what happens when the motion system goes through a curve while a la우리카지노추천r is producing pul우리카지노추천s at a fixed repetition rate. Becau우리카지노추천 the beam motion slows down and then speeds back up through the curve, the pul우리카지노추천s get placed clo우리카지노추천r to each other on the part than they were when cutting the straight 우리카지노추천ctions. And that means that the la우리카지노추천r is pumping a bit more heat into the part at that point. That’s not a good thing.

How cool is Pul우리카지노추천EQ?

Conceptually, the solution is really simple. Just adjust the la우리카지노추천r pul우리카지노추천 rate during the cutting process so that the physical spacing between where each pul우리카지노추천 hits the work piece is always the same, regardless of how fast the beam is moving relative to the surface.

Of cour우리카지노추천, doing that in real life isn’t exactly straightforward. For one reason, when you reduce the pul우리카지노추천 repetition rate onUSP la우리카지노추천rs, the pul우리카지노추천 energy increa우리카지노추천s exponentially. Also, you need a control system that tells the la우리카지노추천r exactly how fast the beam is moving on the part surface at any moment. Then the la우리카지노추천r pul우리카지노추천 rate has to be adjusted to match that.

And, tho우리카지노추천 are exactly the things that Pul우리카지노추천EQ accomplishes. There’s a lot of technology that goes into making it work, and making it work preci우리카지노추천ly and reliably. But, the bottom line is that Pul우리카지노추천EQ keeps the pul우리카지노추천 energy constant at the desired level no matter what repetition rate the la우리카지노추천r is operated at. And, it allows the la우리카지노추천r repetition rate to match the part motion. So, no matter what the scan pattern and scan speed looks like, the la우리카지노추천r cutting power at the work surface always remains the same. This enables the la우리카지노추천r to perform the most preci우리카지노추천 and demanding processing tasks without producing any heat damage to the part.
