The Chemical Connection: Reducing Etch System Water Usage, Part 2

05/02/2024 | Don Ball -- Column: The Chemical Connection
In my last column, I reviewed some relatively simple ways to reduce water usage in existing etch systems: cutting down cooling coil water flow, adding chillers to replace plant water for cooling, lowering flow rate nozzles for rinses, etc. This month, I’ll continue with more ways to control water usage in your etcher. Most of these are not easily retrofittable to existing equipment but should be given serious consideration when new equipment is contemplated. With the right combination of add-ons, it is possible to bring the amount of water used in an etch system to almost zero.

The Chemical Connection: The High Cost of Etcher Non-maintenance

12/28/2023 | Don Ball -- Column: The Chemical Connection
We all understand that day-to-day maintenance and long-term preventive maintenance of etching equipment is a good thing. However, the pressing need to get product out the door in the face of tough production schedules can sometimes cause us to delay necessary maintenance for long periods of time. In some cases, we become fixated on short-term production and forget about long-term stability.

The Chemical Connection: Don’t Just Blame the Etcher

09/25/2023 | Don Ball -- Column: The Chemical Connection
If your HDI or UHDI production process is quality challenged, don’t assume your etcher is to blame. Many factors impact the quality of the final product, so assess broadly, and you may find that the “the devil is in the details.” Generally, the first place most people can get good product specification measurement is at the end of the etching process, It’s natural and easy to blame quality shortcomings on the etcher. By all means, look at your etcher and invest some time trying to improve its performance but don’t stop there. Other factors may be affecting the etch uniformity.
