Tools To Make Your Own PCB

Diy Pcb Banner
Today after work I went to Jalan Pasar to do some shopping. Went to get some tools and supplies to make my own PCB at home.

I made the PCB shown above in college, it was for an IR Transmitter and Receiver project. I’ve always wanted to make my own PCB at home but couldn’t find the time and resources to do it until now.

The first thing I bought was a hand drill, it is necessary to make holes for the components to go through the board. It retails for RM 65 and it doesn’t have any warranty. Fingers crossed.

The drill is pretty simple. No speed adjustments or a trigger, just an on/off switch.

Comes with 0.5, 1.0, 1.5, 2.4 and 3.0 mm drill bits.

I’ll be using only the 1.0mm drill bit. It’s large enough for most components to through. So far I’ve not been able to find any shops that sells 1.0mm drill bit, I’ve got to be extra careful with it for now.

Next are the PCBs. I’m planning to go down the photo-resist route so I bought the appropriate type. They cost RM 11 each.

This board can also be exposed using normal fluorescent light. It takes longer though, around 6 to 10 minutes as stated.

I’ll be using my mum’s reading light. It uses a fluorescent lamp tube.

Next, is the etchant chemical for the photo resist coating. They are actually sodium hydroxide, so I bought them in the crystal form. Don’t show it in front of a police, it looks very suspicious lol. Just mix it with water and you’re good to go.

Finally, this is the ferric chloride acid for etching the copper layer. They cost RM 6 per bottle.

A word of warning for those who are using this. Do not pour it into your sink or drain after using. It is poisonous and corrosive. Doing so will only cause it to end up in your drinks or food in the future. Collect all of the used chemical and send it to your local chemical disposal shop.

I already have in mind what I’m going to make, it’s going to be exciting 🙂 I should be posting an update on the PCB making process in a few days. Stay tuned.

    I often visit your website and have noticed that you don’t update it often. More frequent updates will give your website higher rank &
    authority in google. I know that writing articles takes a lot of time, but you
    can always help yourself with miftolo’s tools which will shorten the time of creating an article
    to a few seconds.

      It’s available freely at electronic parts store. Well, at least in Malaysia.
