Hand Soldering a .5mm QFP Chip With SchmartBoard|ez

[mark33sv]

What kind solder tip used? watts??? wha do u recommend?

I've try to solderin on myold motherboar soby latop's.. it was ash#$#$ but still have opportunity to fix it!.

I used iron tip 30Watts or 25Watts .. i coudn't soldering.

I need to know what kind of tin apply on this cases of soldering..

[Riskteven]

Doesn't the tape charge up a lot of ESD electricity (dangerous for electronics)?

Being in a completely dark room while unwinding tape from a roll or removing tape reveals a faint light where the tape is pulled off. It is electrostatic discharge, ESD.

very nice video

[donrex1943]

the solder on the middle bottom joint looked balled up and terrible.

[eryksun]

tehabc should know that Early Modern English was very diverse, and American English took a unique path to its own standard. In Early Modern English, "solder" can be seen as souder (French), soder, sowder, sawder, soulder, and solder. Here's Philemon Holland (a scholar educated at Trinity College, Cambridge) translating Pliny in 1601: "To soder such gold, there is a proper glew or soder." So, tehabc, 'sod(er) off'. Maybe take some (h)erbs to chill out. Anyway, nice video.

ESD SHIPMATE

[tehabc]

SOL-DER NOT sah-dar. Stop butchering the English language.

@tehabc nobody likes a smartass nerd.

@tehabc NOBODY GIVES A FUCK

OMG i want 1 of those for my 5 nxp lpc1766, 3000 series and a mini break out board for maxim ic MAX8622ETB+ , MAX1878ETC+ ,MAX1932ETC+ ,MAX1790EUA+

If you're doing this to teach, you're passing on bad ESD prevention pratices when you use masking tape on a ESD sensitive component.

[mcliars]

I watched the whole video with my mouth open.

[Spyguy1019]

Wow

[maxdelbruck]

Nice.

[davidjereb]

Oh god. It hurts my heart when I see a cold joint like the last one you did. Why didn't you just use flux?

[Beater06]

wow yes the last one was very bad. But the rest ..respect

[wushuk1ng]

I bet you I can create a short.

[mtttee2]

I thought solder flux was used to remove the oxide layer on the track. Any solder tip that came in contact with solder flux will damage the solder tip because the solder flux contains acid. Why you did not use solder paste instead?

[nealgb]

The technology is to melt the lead free solder in the grooves and water soluable flux allows this to work. One may have to re-tin their tips from time to time...but it is a small price for being able to hand solder very small pitched ICs.

[andaya94]

what do the boards do? just like a big thing to attach and connect everything too>? or what

[6364gg2]

I hava chip in the ZEP package! How do i solder that???

[nealgb]

Do you have a part number...I'm not familiar with ZEP

[6364gg2]

TI calls it that. I found out it was BGA

[nealgb]

if it is 1.27 or 1.0 pitch...we have a board

[jackalope117]

Why do you need the iron at 800 F? SnPb 63/37 melts at 362 F. and all the SAC alloys melt I think around 217F to 240F. You shouldn't need more than 650 F to 700F. Unless there is something i am missing.

[rwboghdady]

nice work

[rkstyle1]

nice !

[30GB]

lol shmart board

[jckzz]

I hate idiots that pronounce solder as 'soder'.

Therefore I hate this video.

[pkwillard]

Get used to globalization.

Those "Idiots", like in this video you might notice, speak American english... the L is silent. On the other hand, Aussies and Brits pronounce the "l". If he pronounced the L, he would not be "American"... but then he'd have the wrong accent.

I see you deal with diversity well.

[RoC1909]

Wow!! That's pretty cool. I could see myself soldering each one of those leads individually and solder getting everywhere! Thanks!

[SEINORTACO]

to be quite honest its like watchin paint dry but thanx for the help and nice vid

[davemaster99]

what flux do you recommend

what solder pitch use for this

many thanks

[grenouil1970]

???????

[TruAnRksT]

""flux is to clean the surface so the solder sticks I think.""

Nope, its to conduct the heat into the metal better.

""WHAT IS THE FLUX USED FOR ? is it conductive ??""

Yes in a way, it's THERMALLY CONDUCTIVE but not electrically conductive. It also helps protect the hot metal from the temporary but immediate oxidizing effects of being exposed to open air.

[jkgamm041]

I commend you for an excellent demonstration. Very well done. With all the surface mount soldering that I have done, I have never seen a

SchmartBoard with solder filled grooves going to the toe lead on a gull wing smd. Feel free to view my SMT demo's on vertical drag soldering.

[zloben9000]

OMG .. that so small !

WHAT IS THE FLUX USED FOR ? is it conductive ??

[ze12o1]

flux is to clean the surface so the solder sticks I think.
