Making a PCB-Printed Circuit Board-DIY-PART II-Etching & Liquid Tin

Step by step process for making Printed Circuit Board (PCB) from a positive artwork. Exposed Copper Clad board is etched in etchant and then cleaned. Finally Liquid Tin plating is applied to copper traces.

Hi there..Very nice tutorial..I have one question though..What is the crytals for?At the tinning stage. And what is called?

Thanks :)

@naw1212 After awhile my 'Liquid Tin' gets crystals in the bottom of the container.

Where would one learn the "programming" of such boards?

[X2YeZCAMCNC]

What do you mean "programming"?

[dunesandworm]

great video, you should make dvd's.

@X2YeZCAMCNC Go learn electrical engineering from a university. Takes 4 years.

wear gloves please.

In my part of the land, we write the word "DANGER" normally, not mirror imaged! HA HA!

[klaz48]

Dont over etch/ under etch that board now!

[naw1212]

oh ok..thanks for prompt reply.

[TrickyNekro]

Man, do you happen to know somewhere that it is possible to buy liquid tin and ships to Europe???

Dude, ferric chloride is potentially dangerous, it's corrosive and its vapors are irritating for the respiratory system. Shouldn't you wear gloves and protective mask and glasses?

I've been using an incandescent (automotive style) trouble light to heat the FeCl directly w/o a water bath. Just put a 100 or 120 watt bulb in there and hang it above the tray (or below) to heat it. Works slowly, but after about 10 minutes it's pretty hot. The lamp won't be capable of getting the acid to boiling/scalding temps so that's good from a safety point of view if you somehow forget it.
