sorry for the late response... the white pen is solder flux... (Stanol minifluxer 33) i removed the solder bridge simply by adding solderflux and contact a short time with the soldertip... (not shown in the video) i did the video only for testing and showing my 1st experiences with solderpaste...... i see that many people like this kind of videos so i plan to do more in the future but on the other side those many negative comments makes me sad and demotivated to show and do more stuff... and again.. this was my 1st experience with solderpaste normaly i use hotair for desoldering and for soldering i use a solderiron with special soldertip thanks for watching and understanding :-)

The grey paste is called solder paste and we are talking real solder paste not solder flux paste that is sometimes called solder paste. The difference is that real solder paste contains metallic powder in a flux compound while solder flux does not. Real solder paste should indicate the metallic compound such as silver, copper and other metals in their periodic label labels like Au, and others. The hot air gun is part of a 'reflow station'. granted, it is possible to use a hair dryer or heat gun but those have a much wider effect area due to the obviously bigger or wider 'nozzle'. In addition, if they are not temperature controlled, then you can face problems... especially heat guns without temperature control while a hair dryer would most likely not get as hot but might be hot enough for the solder paste to melt. Note: solder paste tends to melt at a little bit lower temperature than solder wire. This is why you don't need to get excessive with heat. Alternatives to using the hot air tool is to use a convection oven with temperature controls that you can set that would be under 300 degrees. Basically that is what the industrial equipment is known as a "reflow oven" which is basically a convection oven.Some are infrared or vapour phase ovens en.wikipedia.org/wiki/Reflow_oven Occassionally additional flux is used with solder paste. With reflow method, you don't need ultra steady hands just ensure you have solder connecting the pins of the components to the solder pads, via, etc. while assuring you correct any bridging of pins so that you don't create a short where you don't want it once you apply electricity to the circuit board. Lets keep in mind that we are looking as a really component with a high resolution camera zoomed into the component. Even what is a relatively stable hands can look like it is very shaky but lets remember that you are looking at something 10x10x10 (3d space) or 1000x magnification to the real scale so movements are exaggerated by 1000x. Try soldering with a camera in your way. It's not that simple.

I seem to notice that most videos remove the existing solder from the pads on the boards. In my experience, I don't do this since I'm just going to add some back if needed and I think it is just an extra step that might ruin the PCB. I think it helps the chip lay flat and orient itself when initially soldering but I like to use a complete melt of the chip area so that the solder can "suck" the chip into position as it wets the leads.

Not really. The old solder is lead-free and is harder to work with, requires higher temperatures and is more brittle too. Leaded solder requires lower temperatures and you do the work quicker than you would with the lead-free. You just need a quality leaded solder wire and all is good.

Laying paste across the pads is actually common practice. Check out some of the SMD soldering tutorials from Pace for some good info. With enough flux (but not too much) to lower the solder's surface tension, bridging is not an issue. Also, if you don't use enough flux the excess can be easily wicked away. As I'm sure was done in this case because the end result was clean.

Никогда не делайте так как на этом видео. 1) сопло фена выбрано неправильно. нужно ставить квадратное (или вообще сопло не использовать) и греть весь корпус сразу на малом потоке. такое сопло вызывает локальный перегрев и может вызвать трещины тонких проводников - плата может отказать через пару месяцев. 2) работа с фитилём - тут вообще трудно что то комментировать. нужен обильный флюс, а не этот дурацкий карандаш (карандаш в помойку немедленно). EFD 6-412 flux plus (лучше) или MCN-UV80 (по бедности). на жало нужно взять немного припоя, чтобы в начале работы смочить фитиль. двигаться надо сразу по всей длине и гораздо быстрее. после фитиля нужно как следует промывать - на фитиле бывает очень плохой флюс, который даёт черноту. 3) из шприца невозможно нанести пасту равномерно. нужно взять кусочек тонкого картона и вырезать из него трафарет - окошко по длине выводов и шириной чуть меньше 1мм. через трафарет нанести дорожку пасты шпателем, сделанным из той картонки же гораздо проще. толщина картонки ~0.5мм. получится хорошая равномерная дорожка. 4) держатель с крокодилами никуда не годный (деньги в помойку) - нужен держатель типа пружинной струбцины.

Order some component stencils and apply the solder paste using those. You'll not need to hold the hot air gun on the part so long and you'll reduce the risk of overheating the part. Take a look at the heat profile for the part pay close attention to the overall dwell time.

Most of the times there aren't enough data address lines on the PCB for that kind of upgrade. Manufacturers need to save every single square millimetre they can, so any unneeded copper traces on the PCB are skipped. If you're lucky, you can upgrade to the maximum possible for the already existing address lines already there, but not anything over it.
