For electronics, your knowledge probably follows a bit of a bell curve over time. When you start out, you know nothing. But you eventually learn a lot. Then you learn enough to be comfortable, and most of us don’t learn as much about new things unless we just happen to need it. Take SMD components. If you are just starting out, you might not know how to find the positive lead of an SMD capacitor. However, if you’ve been doing electronics for a long time, you might not have learned all the nuances of SMD. [Mr SolderFix] has been addressing this with a series of videos covering the basics of different SMD components, and this installment covers capacitors.
If you are dyed-in-the-wool with SMD, you might not get a lot out of the video, but we picked up a few tips, like using a zip tie for applying flux. The video starts with an examination of the different packages and markings. Then it moves on to soldering the components down.
We haven’t run into the little trimmer capacitors, so that was new to us, also. It is a great idea for a series, and the photography of the solder is very clear and useful. Worth a watch!
SMD parts don’t have a lot of room for markings, so they can be a bit cryptic. If you show up at a Supercon, you can always join us to show off your SMD soldering skills.
I used smd at work its ok with the profesdional rework dtation and microdcope i use it ad a hobbyist as well i use large magnifier glass with lamp and fine solder and small tip soldering iron i used solder pastse at wirk the parts are small so its easy to lose them work well at radio frequencies the probkem is ceramic smd capacitors have no markings and tantalum capacitors the bar is positive and smd electrolytics bar is negative the bar id black marking on top the smd ekectrolytics are a bit if a pain to hand solder i like smd ad i likr yo make small miniTure circuits i also solder wire end parts to pcb track
You misspelled ‘hobbyidt’. ;)
LOL
Hackaday should do a post about those new-fangled keyboards that have punctuation keys.
Ahhh, this is the perfect article to link the crazy guys who build Beer bottle capacitors to power up a ww2 carbon arc lamp. But coudn’t find the link :-(
And of course the guys was/were german :-D
