Those close-up shots of perfect drag soldering are like porn for electrical engineers.

The liquid in the syringe is a no-clean high solids tacky flux. Flux is activated by heat. It is a chemical cleaning agent which removes mild to medium oxides and prevents re-oxidation. The flux also reduces surface tension allowing the solder to wet rapidly to create the metallurgical bond.

@Bylga the Pace brand name is "Miniwave," but there are lots of copies of it out there. Pretty much a single sided chisel with a reservoir on the flat side. I think if you used it on some surface mount components a few times you'd see how easy it really is

@ATBatmanMALS31 Ok thank you.
-
@Bylga it isn't the concial tip at all, it's called something else, sorry if I steered you wrong. I'll find out what it is today
-
@ATBatmanMALS31 Thanks for your help.
-
@Bylga conical tip makes it real easy
-
I still need to learn how to drag solder! =(

What is the name of SMT camera which is on video trough 3:96 - 4:01
-
Soldering could be considered an art form.

i thought i new how to solder until i saw this video
what temperatures are good for ROHS tin .. since I started using ROHS tin my soldering isn's so shiny as it used to be :(

ROHS (lead-free). Best manufacturing practices for lead free, SAC alloy (SAC 305 - tin, silver, copper.) Ideal tip temp is 650 F - 700 F maximum. Sac alloy produces a visual characteristic identical to a cold solder fillet. SAC alloy also produces an increase in "wetting contact angle." Here's a trick.. Soldering lead-free with a bottom pre-heater at around 150 - 200 F or from a heat gun promotes much better wetting as silver has a higher melting point to achieve its liquidous phase.

I am a US Navy 2M (Mini-Micro) solder inspector. This work is right on. I wish my students could do this so quickly. Heck, I wish I could do this so quickly.

A number of my IPC and SMTA associates are former 2M. They use to train a lot over there at NAWS (China Lake) in Ridgecrest and at Redstone.
When I drag solder, I use a high solids flux syringe, a no-clean tacky flux or an RMA. My speed of travel is determined by my wetting action. I control the dwell time so I dont thermally shock my SMD's. I also know I am getting Class 3 heel fillets and 100% side joint length by a "one touch" technique. NASA-STD-8739.2
& IPC-J-STD-001.
