Quartz tank is an equipment used in wet process particularly helpful in semiconductor wafer or substrate production.  It is a prime choice of companies in the industry because of (1) high purity and (2) chemical compatibility.

Speaking of high purity, it is important to maintain the quality of the equipment in order to achieve the right quality of the finished output. And this can be realized by considering this option: quartz repair and restoration. This is more practical (in most cases) than getting a brand new replacement.

Compelling reasons why proper repair and restoration is necessary for quartz tanks:

• Because there is a need to remove the residue of chemicals used in the wet process, which can take a toll on the seals, housings, wiring, and quartz chamber.
• Because, as I said earlier, it is more practical than acquiring a brand new one; it costs substantially less than replacing it with a new one.
• It increases its lifespan and maintains its reliability as a wet processing tool.

To ensure the quality of repair, it is important that you entrust the job to a proven capable of doing what needs to be done. Here are some tips:

• A wet etch company that has been in business for quite long is, in most cases, more reputable than the new ones; when picking a service provider, you would want to have such company treated with higher priority.
• Another gauge for a company's reputation is the number of recognitions it has recieved through the years; and, the number of complaints raised by other clients as well.
• Pick a company that can give not just the quartz tank service you need but one that you can establish rapport with, considering that this client of service involves continues client-service provider business relationship.

What are included in a standard tank rebuild? A good tank rebuild service provider should be able to provide the following:

• Performs chemical cleaning, burn-off and fire-polish of quartz chamber;
• Add all new heaters and insulation systems;
• Add all the needed sensors and wiring;
• And new housing and flange;
• Performs complete quality control and inspection per new tank procedures; 
• and, performs all the works completed using ISO 9001 procedures.

Again, the quality of a quartz tank is critical for a high purity process; make sure you are able to get the right service provider and this can be achieved if you are knowledgeable customer.
