Make certain your system measures up

Blend chemicals as if your process results depend upon it

Sometimes, when exploring front-end fab process and productivity systems, it pays to begin at the end. Ask not only about yield and quality, but the efficiency of the entire process that they feed. That’s the difference between experimental and trial runs and the long-term, end-to-end viability of a line.

Kinetics continues to surprise HVM companies with a more holistic look at process engineering, even when the spotlight is on chemical blending systems. Often seen as workhorses in industries that view themselves more like thoroughbreds, there’s significant opportunity attached to the daily blending of process chemistry.

That’s because a back-end focus on enterprise success requires that every stage and step get rigorously examined for the risks (and rewards) attached to them. In the case of vital chemical blending, at least four elements deserve focused attention.

Spotlight #1: WEIGHING ACCURACY

There’s no sense chasing chemistry once it’s flowed into the process through a chemical blending system (that may or may not be part of the same hardware configuration), unless the upfront measurement of each chemical has been dialed in. Kinetics applies precision weighing technology and a proprietary blending algorithm to each chemical, with common volume ranges covered by the CB 100 (medium capacity to 8,000 liters/day) and CB 200 (high capacity to 15,000 liters/day).

Spotlight #2: CALIBRATION AND MEASUREMENT

Kinetics employs conductivity-based feedback loops to ensure proper blending is occurring. Compared continually to predetermined conductivity set points, there’s no escaping the blender’s watchful eye at any daily volume level. Then, the blend tank continues to circulate the mixture until the proper concentration level is reached. Pumping resumes with confidence, knowing the chemistry is on spec and prepared to perform. This is yet another place where surprises are both unneeded and can serve to defeat targeted production outcomes. Kinetics manages up to three constituents, plus DI water, to tight tolerances.

Spotlight #3: OPERATOR CONTROL – AND SUPERVISOR OVERSIGHT

Back-end results in a commercial environment hinge on a multitude of factors. Many companies struggle to optimize their yields on the consistency side of the equation. Controls embedded in a viable blending system carry their own sense of pragmatic paranoia: status, alarm, calibration, valve box status and runtime screens all are part of what’s necessary shift after shift—to adjust, maintain, and gain confidence in the entire process in a visually compelling manner.

Spotlight #4: SAFETY NO MATTER THE OPTIONS

While numerous backup, recirculation and measurement enhancements should be part of a supplier partner’s offerings, there’s no room for wondering whether the installed blender is capable of safe options. Visual and digital checkpoints, along with access restriction and door interlocks, serve vital roles in human, product and facility safety. That extends to the environmental implications of leaks anywhere in the system. Again, vigilance must weigh heavily in selection of a blending system.

Four spotlights among the many spec, interface and financial considerations feed plant chemistry. All reflect a belief in the primacy of plant performance. All rightly elevate the importance of a comprehensive blending system in the entire process.
