Metis-7000 K2CO3 is a development solution automatic controller. It can analyze potassium carbonate (K2CO3)
concentration which is active component of process solution used at production line of printed wiring boards and
replenish ( output signals for replenishment) supply solution automatically.
Can also calculate the amounts of dissolved dry film resist and liquid photosensitive solder resist at advisory
level which are increased by progress of processing.* It helps you to know the timing of renewing the process
solution.(*It needs consultation. Please contact our sales staff for detail.)
Can maintain high analysis accuracy by washing sensors every after analysis cycle ends.
Can perform the optimum control of analysis and replenishment by simple parameter change.
Easy to integrate into specification of production line.
Contribute to cost down by reducing amounts of use of process solution and labor costs for analysis and
replenishment.

Start
Starts analysis flow every after user- fixed time elapses.
Samples chemical solution by equipped pump.
Sampling
Analyzes chemical solution concentration with chemical reagent .
Analyzing
Prints out and saves analysis data, and transfers it to USB memory.
(External data communication is available as optional choice.）
Calculating
Replenishment
Cleaning
Calculates necessary replenishment to correct the processing solution
concentration to preset value on the basis of analysis result.
Replenishes supply solution into treatment tank by controlling replenishing
pump with output signal from the controller.
Cleans reaction cell and sensors and stands-by till next analysis
flow begins.
Note1）Please use our designated genuine parts or reagents for maintenance and running in order to prevent unexpected
troubles.
Note2）Please be notified that we may change the specification or appearance of the controller for improvement without
notice.
Note3）So as to maintain analysis accuracy, we recommend periodical maintenance or adjustment by our skilled engineer.
