WTFFFFFFFFFFFFFFFFFFFFFFFFFFFF­FFFFFFFFFFFF ka boommmmmmmm

how can u cool down the PCB using water....What the well

[0815521576]

Can I use a soldering iron instead of the oven?

[xXDominoXx]

does the solder paste stay gooy even at room temp?

or are you placing the electrical components on solid solder?

and then it all solders to the components in the microwave oven?

[patsaxon]

I have seen such boards assembled by SMT machines, but never by hand. I have worked on an assembly line soldering SMT components with a hook type of soldering iron, but that was very hard and I had to look through a microscope.

[copperheadjr100]

hey, what exactly can you use a pcb for? do they work in computers?

[hityou123]

Which tool do you prefer - vacuum pick and place or Tweezers?

[flesknava]

@hityou123 Vacuum pick and place for prototypes and tweezers for rework.

[HumanityWins]

nice stuff. didnt know you can wash computer stuff under water :D

[pikuorguk]

@HumanityWins you can if it's not going to trap water inside it - washing an LCD display or anything not sealed would be bad.

What is the brand of the solder paste and where can I buy in internet?

[vyshemirsky]

Question: how do you avoid bridges between IC pins? Will this method work on a DIY etched PCB without a solder mask?

cool!

[flesknava]

@vyshemirsky Thanks :) You can use this method for PCB`s without solder mask without any problems. For leaded solder paste it´s not so critical how accurately you dispense paste to the pads. You can even draw a solder paste line over the pads and surface tension will draw paste to the pads when solder melts. For lead-free solder paste it´s important to dispense small solder paste dot directly to the pad and avoid any splatters between pads because of weaker surface tension.

Hi, do you maybe know where I could get this solder paste delivered to Australia? thanks in advance

[dogmadogma]

Question: Will this paste work on soldering wires on pcb boards instead of using soldering irons? Thanks for your info. although I wonder if you will reply seeing how this video is bit old.

[flesknava]

If you mean cables, wires, connectors and other through hole components yes it's possible. But I would do it with soldering iron and cored wire if you don't have a very high volume production.

[RythmTR]

yeah something made in canada!

[Penfold8]

I'm surprised you didn't have any resistors tombstone on you.

[addzkebabs]

since when did you run electrical components under water?

[carloscavalcanti]

I also do it all the time. No problem, with no electrical current. Big surprise, eh?

[luispiero]

lo que se busca es calidad que bien

[luispiero]

que bien ha

my god you're fast...like that android in Alien 2 with the knife

40 year old virgin comment my friend

[fluggum]

Can you "cook" the same card several times? I.e. placing and cooking small components first and do larger components like connectors in a second "cooking" sequenze? Do you have to treat previous done solder pionts in any way?

[flesknava]

Yes you can "cook" or reflow the board several times. Two times goes without no problems. First you can place and reflow resistors and capacitors and second larger and more heat sensitive components like integrated circuit. You don´t have to treat solder joints between several reflows.

[EmmanuelDavidIndia]

It must not be !

[fluggum]

For how can you use the solder paste? Can it be stored after you've opened it. I guess I will never use a whole tube on a single prototype board.

[flesknava]

Put the paste syringe to the slidergrip bag and store it in the fridge. I have use 1,5-2 years old paste stored like that with good results. It´s not recommended to use two years old solder paste but like I said, it´s not rocket science :)

[fluggum]

How long do you "cook" it in the oven?

How much heat do you use?

[flesknava]

I think it was only 2 minutes. Thermometer didn´t work so I only have to guess the temperature and watch cooking through glass. It´s not rocket science :)

[oemguide]

what's the oven? DIY?

[flesknava]

It´s normal electric toaster oven with DIY digital thermostat.
