SMD Components self-align in toaster / skillet reflow

[marz3335]

Can you reflow "some" components and then come back and do more later? Or is it a must to ALL the components at one time? Also -- is it possible to also have through holes for through hole components to add later (or will they fill up with solder)? (Depends on hole size?)

thanks !

[xoen6]

Fav.

Period.

[Chavagnatze]

Doesn't extended temperature exposure at and past the element operating temperatures destroy the components?

[framelocator]

The world should respect the Geek.

[gamakishy]

Nice reflow, first one is clean and perfect, second had a little bridge though.

[DrModd]

Just one dumb question, how do the components survive?

[Bracerjack]

That's awesome!

But does the chip itself survive ?

Would it still work ?

[UberLifeTroll]

Fuck all of you who are calling us geeks. Just because we're better than you gives you no right to bully us you niggers.

[oidium45]

@UberLifeTroll dude... we are geeks! Learn to love it

[UberLifeTroll]

@oidium45 Calling me a geek is like calling a black guy nigger.

[oidium45]

@UberLifeTroll Oh, my mistake.. Your not a geek your a fucking idiot

[UberLifeTroll]

@oidium45 I'm a fucking idiot? It's you're and you're a fucking idiot for not knowing how to spell.

[oidium45]

@UberLifeTroll You have some serious issues little man

[cloudsifter11]

@UberLifeTroll true geeks don't use racial slurs. Epic Fail. What level DungeonMaster are you?

[UberLifeTroll]

@cloudsifter11 I am level 69 because that is what I do with your brother best.

[TheNuclearWatermelon]

this is a geek's version of the superbowl :D

[DigiTan000]

I gotta try it this week. The parts are already soldered well enough to work, but it just "looks rough" with uneven solder.

[invalidcookie]

Damn second reflow bridged.. -_- 

[coilsinamotor]

this is what we nerds do at parties!!! ;)

[kttkttkt]

reminds me DOUBLE RAINBOW guy

[TheTommer777]

that has a mini usb port!

[invalidcookie]

@TheTommer777 Looks like something from Team Xecuter

[konayasai]

I liked the chime sound in the end; it sounded just like you were microwaving a burrito or something :)

[reply4reply]

pfff i see this everyday, these guys seem like they just poped their cherry

[ppp56]

Temperatures for soldering should be in the datasheets for the parts you are soldering. There should be a graph of temperature vs time, showing what preheating should be applied ect :)

[vododragon]

Really neat re-solder a PC board and burn up your microprocessor not really a bunch of smart people out there.

[Miketar2424]

@vododragon processors can take temps of up to 250 C, and still work afterword.

[markolo25]

i think shorts probably won't happen because molten solder usually travels towards the place with most heat which probably will be the pins because they attract heat better than the covered copper of the pcb.

[Automobilie]

Doesn't this cause shorts and damage components?

[eddiequest4]

"thermal couple"...lol

Neat vid. Think I'll be in the kitchen for a while. :P

[graymalkin1234]

Hmmm... FTDI FT232RL....

[pr014m3r]

Bing! :D

[kefsound]

@pr014m3r OH NOES reflow soldering is not for NOM

[toober529]

Did I hear someone say "Hella bridge"? lol!

[palmisano]

What toaster oven did you use? Would you recommend the oven or the skillet more?

[clopoff]

слишком много пасты,некоторые ноги замкнуло.

[azayles]

omg lol, I bought two of those FT232 chips a couple days ago thinking the pins would be wider spaced (SOP instead of SSOP) and my GOD they are a PITA to solder D;

[charlesbonkley]

Were any of these components tested after this process? Don't most reflow ovens use more convection heat rather than IR blasting down on the components? I would think after sitting in the oven for so long, soaked with IR that most plastics and IC internals wouldn't fair very well.

[mashersmasher]

how do you get rid of those bridges after you're done? with a hand iron?

[MrFacet]

At hackedgadgets this video is shown (dated 6 dec ) and Alan Parekh says: use solder wick to remove those bridges.

[lambedan]

Solder wick works real well for getting rid of those bridges.

[jkgamm041]

It can be done very quickly and easily without wick. Use a drop of a good No-Clean flux like Kester 951 w/ 2% solids, 959 w/ 4% solids or an RMA tack flux in a syringe.

Use a hoof tip (single flat) or a chisel. Touch down directly on the pad. The flux reduces surface tension as it is a surfactant and the solder follows the heat source, re-flows and pulls the bridge immediately for a Class 3 fillet. Wicking commonly causes abrasions and removes mask. There are better alternatives.

[Jakobfrog]

What is the grey gel you use called? One of my classmates tells me that it's called smd but I can't seem to find any other videos where this particular method is used

[s1rk3t]

It's solder paste. Little balls of solder suspended in a flux. It's generally applied via a stencil or programmable pick and place machine with a solder dispensing needle.

[MrFacet]

See the comment section...: solder paste, SMT soldering.

[ig33ku]

250C or 250F?

[s1rk3t]

250C. 250F won't melt 60/40 solder- let alone ROHS compliant stuff.

[MD2389]

Yeah, how hot was that oven running, and what was the timer set for? I'd love to be able to have that to fall back on, should I do something stupid.

[davidjereb]

Wow! Some awesome stuff right here : )

[lodevijk]

What was the temperature of the toaster? I'm curious about the possible toasting of the ICs.
