Q HI, We have used your Ferric Chloride in the past which dissolves nickel as well as the copper .Could you tell me if this product will also dissolve nickel.
A Hi Gary, thank you for your question. This should not be a problem however you may wish to make a stronger solution, and adjust the temperature and time it is immersed for in the solution.

Q May be a silly question but is this product compatible with the Mega Electronics Etching Lab station PCB500 I have been previously using ferric chloride pellets in it.
A Hi Gary. Thank you for your question. This etchant is suitable for use in etching tanks.

Q Hi, would this etchant be compatible with the PCB board 34-0176? if not which one would be? thanks.
A Hi Richard. Thank you for your question. These PCB fine etch crystals would be suitable for use with the mentioned boards.

Q Hi how do we dispose of the used etchant?
A Hi Leanne. Thank you for your question. Once diluted/used this can be taken to the local county council for disposal. If not the copper can be filtered off, and the remaining liquid can be diluted with water to be poured down the drain - however this is not always suitable practice - the remaining copper can then be disposed of in the bin. A waste tip is normally the best option, lots of schools and colleges have a specific collection company that will dispose of old and dangerous chemicals.

Q The smaller pack of this etchant is suppied in 4 x 100g pouches, which allows making up only 0.5 litre at a time and keeping the rest of the powder sealed. How is the larger pack shipped ? All in one tin (which might attract damp when opened) or in multiple pouches ike the smaller pack ? Thanks.
A Hi Nick, thanks for your question. The larger 1.1Kg tub is just a single unit and is not split into smaller items/pouches.

Q What is the shelf life of the working solution once made up.
A Thanks for your enquiry Steve. Once made up, the shelf life of this product is about 2 months but you can add more etchant to bring it back slightly. Undiluted the crystals can be stored for 2+ years.

Q 34-0392 will this make 2000ml of pcb etchant solution? Trying to keep my costs down, radio shack do it already bottled but is 3x as expensive as this if it is the same product. Thank you.
A Thanks for your enquiry Mark. Yes this product will make 2 litres of PCB etchant solution.

Q What is the shelf life of the etchant if stored in its original packaging?
A Hi Ken, thanks for your question. This is advertised as 2 years, but the manufacture states it is fine up to 5 years, and possibly beyond.

Question by Susan
Tuesday, March 20, 2012

Q For occasional use i.e. in lab or workshop (not commercial production) is it okay to water wash the PCB after etching with the flushed water going to the normal waste water drain? Obviously the remaining solution in the tank (should it need changing) would be collected in a sealed container and disposed of correctly.
A Hi Susan, thanks for your question. This would be ok to do, just as long as not lots being done. However the machine is only a water feed down the drain.
