Mikhail, greetings. where are you from? The soldering station I used is a Hakko 951 with a drag soldering tip. Some call it a hoof tip or a single flat. We get them here in the USA for around $250.00 and another $100.00 for a few chisel tips. drag soldering tips, etc... This is considered a cheap station. The Weller rework station I use in my recent videos retails for around $2500.00. I can teach a person to duplicate my work using a cheap $150.00 station called a weller WESD51 Digital. Tips are about $4.00 each and last a long time if maintained.
Big numbers for a student, I recently bought a cheap knock off soldering station for under $50 (I know most likely garbage.) I'm still waiting for it in the mail. reason behind purchasing that, I Really want to get some experience, there is only so much a professor can teach you, a lot of skill and knowledge comes through personal experience. Once I get into this field I will start purchasing better tools. Speaking of which, starting my first electronics job tomorrow. One more thing, what microscope would you suggest for smaller PCB SMT work?
For component removal of SMD's including chips, I only use hot air and flux the pads with Kester 741 rework gel flux high solids. See my other videos on J-STD-001 and rework. I demonstrate hot air removal of flat packs.
So i know about soldering enough to know soldering this elegant and effecient is not the cause of a single link in the chain, but all of them. Could you let us know what equipment you use? The soldering iron, the solder alloy and flux type for its core, the type of rosin flux you use, etc? I have found a poor choice on any of these is enough to turn any solder job sour.
+Richard Smith - I am using a Hakko FX 951 soldering station with a large hoof tip sometimes called a single flat or bevel tip. They are made for multi-lead and drag soldering. For alloy I use kester SAC 305 lead-free water soluble at 700-750 F and prefer a Kester water sol tack flux for best wetting. I dont use rosin or RMA unless it is called out on a contract. Water sol has a low solids aggressive flux which wets beautiful and cleans up easily with a brush and water.
Kimwipes. Static dissipative wipes. They leave the least particulate matter. The cheaper generic type of brands will leave particulate all over your board.
your just showing off lol. I wish I could do this . I struggled the other night trying to solder a chip to the board the chip got bridged and I struggled to remove the bridge managed in the end with solder wick. but the way you guys do it. it an art
