Contac S4 Maintenance: Filtering Bath 5

You must be wearing proper PPE before you do anything with bath 5 of the Contac

Safety glasses/goggles

Apron

Gloves

Turn off the Contac before proceeding

Every so often the Contac S4 will tell you that bath 5 needs to be filtered

Contaminants from the environment and FR4 boards can lead to lower quality plating

We can remove these contaminants with a filter

The tubes and filter for draining the Contac are located on the top shelf of the LPKF cabinet

The arrow indicates which way the chemical should flow through the filter

You will need to remove the floating balls before you can drain bath 5

Use the slotted spoon to remove the balls and place them in glass beakers

The slotted spoon is located in the cabinet beneath the Contac and there are glass beakers in the back room

Open the cover on the front of the Contac by pushing on it

Remove the plug from bath 5 by pushing on the ring around the plug while simultaneously pulling the plug out

Insert the tube marked with 5

Insert the filter into the other end

Direct the filter into an empty Copper Plater 400 jug from the back room

Twist the blue knob to begin draining the bath

Once the bath is fully drained, pour the now filtered chemicals back into the bath from the top

Pour the plastic balls back in

Cover the bath with the lid

We have to tell the machine that bath 5 has been filtered so that it can reset its internal timer

Turn the machine on and tap the hamburger menu icon

Tap Settings

Tap Service

Tap Reset on Copper-plating filter

Tap Yes

The timer is now reset. It will go off when it's time to filter bath 5 again
