DIY SMD Resistor Capacitor Kit
If you’re new to electronics, I highly recommend starting out with through hold components. They are much easier to work with – much easier to breadboard. But, once you’re comfortable with through hole stuff, eventually you’ll be forced to get into SMD(surface mount devices) – either because you need a compact design, or the IC your working with only comes in a SMD package.
First thing you should get when making the transition to the SMD world is a SMD resistor and capacitor kit. You can buy them at a lot of places online. Ebay has a good selection of them. Some come in a box that opens up to little tiny compartments – but they can be really expensive. Other seller sell them in little baggies or cut tape for next to nothing, but then how are you going to store them? One solution is a binder. Adafruit sells a “SMT 0805 Resistor and Capacitor Book” that’s worth looking into. But I wanted something more modular. Something that I could build myself, and something that I could add to as time goes by, and my needs change – I didn’t want to be locked into only pre-slected values that I didn’t choose. And…I wanted something that would hold tens-of-thousands of parts.
First I picked up some of these tiny little storage boxes. You can get them on ebay (although I hear the quality isn’t as good) – or (again) Adafruit will come to the rescue! https://www.adafruit.com/index.php?main_page=adasearch&q=smd
If the pictures don’t show it – they are interlocking – so you can arrange them in any configuration you want. And they can be reconfigured on a whim. Oh…one of the things I really, really love about them – they have a spring loaded, leaver actuated lid that you can (with one hand) – click the unlock tap – and it opens. That means that you can have a PCB with loaded up with solder pasted, and with one hand steady the board, refer to your PCB layout, unsnap a lid, pic up a part (with tweezers), close the lid – place the part – and move on. All in one easy motion. I can’t think of a better solution to hand placing SMD parts!
It’s also worthy to note that Adafruit sells a antistatic version – could be useful for static sensitive parts – but I haven’t had any issues with chips – including attinys, atmegs 328s, 555′s and an assortment of opamps.
But here’s a handy tip I’ll try to cover in another blog…..rub the inside of the compartment with a household dryer sheet anti static cloth. You know – the same stuff you dry your clothes with. It seems to work a treat! Not sure for how long – but as I said, I’ve been storing smd chips in these for years, with no ill effects at all.
Next – hop onto ebay and pick up the resistors and capacitors. This kit was $20 shipped for 5000 resistors and 2000 caps. Not bad!
They came in little baggies like this – It’s nice – but no way handy.
Next – fire up your favorite vector image editor (I use illustrator -but there is an opensource software called inkscape that is just as good for this type of thing.
Print the sheet out. You can edit the original document if you’re kit was different then mine, or you want to create your own kit.

I used AVERY 48363 labels. I highly recommend covering the labels with clear packing tape before cutting them out and applying them to the boxes to prevent damage to the labels.
And here are the results:
