- Hand soldering surface mount components to IPC Class 3 standards, which represent the highest level of quality and reliability for electronic assemblies, requires a high degree of skill, precision, and adherence to specific guidelines. Here's a step-by-step guide on how to hand solder surface mount components to IPC Class 3:
Materials and Tools Needed:
PCB with surface mount components
Surface mount components
Soldering iron with a fine tip (temperature-controlled)
Soldering station with adjustable temperature control
High-quality solder wire (lead-free or leaded, depending on your requirements)
Flux (preferably no-clean or water-soluble)
Tweezers or vacuum pick-up tool
Magnification equipment (microscope or magnifying glass)
ESD (Electrostatic Discharge) precautions (ESD wrist strap, ESD-safe work surface)
Procedure:
Preparation:
Ensure your work area is clean, well-lit, and free from distractions.
Verify that your soldering equipment is calibrated and functioning correctly.
Put on an ESD wrist strap to prevent electrostatic discharge damage to sensitive components.
Component Placement:
Use tweezers or a vacuum pick-up tool to carefully place the surface mount components on the PCB in their designated locations.
Ensure proper orientation and alignment of each component.
Flux Application:
Apply a small amount of flux to the solder pads on the PCB where the surface mount components will be soldered.
The flux helps in solder wetting, removes oxidation, and improves solder joint quality.
Soldering Iron Temperature:
Set your soldering iron to the appropriate temperature based on the solder alloy used and the specific soldering requirements. For lead-free solder, temperatures are generally higher than for leaded solder.
Soldering Technique:
Tack solder one corner or one pad of the component using a minimal amount of solder.
Use the soldering iron to heat the solder pad and the component lead simultaneously.
Once the solder melts and flows, remove the soldering iron, allowing the joint to cool naturally. Do not disturb the joint during cooling.
Ensure that the solder joint has a shiny appearance, indicating good wetting and proper solder flow.
Use magnification equipment to inspect the solder joint for any defects, such as bridges, cold solder joints, or insufficient solder.
Repeat and Inspect:
Continue soldering each pad of the surface mount components one at a time, ensuring high-quality solder joints for each connection.
Periodically inspect each solder joint using magnification equipment to maintain IPC Class 3 quality standards.
Cleaning (if required):
If a no-clean or low-residue flux is used, cleaning may not be necessary. However, if cleaning is required, use an appropriate cleaning agent or isopropyl alcohol to remove any flux residues.
Final Inspection:
Conduct a final inspection using magnification equipment to ensure that all solder joints meet IPC Class 3 standards for quality, appearance, and reliability.
Documentation:
Maintain records of the soldering process, including temperature settings, component placement, and inspection results, for traceability and quality control purposes.
Hand soldering surface mount components to IPC Class 3 standards requires patience, attention to detail, and rigorous quality control. It is essential to ensure that each solder joint meets the stringent requirements of Class 3 for high-reliability applications.

I literally would watch a video like this if it was 4 hours long... Thanks!
Could you tell me what kind of flux you use? It works perfect! 👍
nice
Great video on hand soldering surface mount components really good
killer skills but the soundtrack sounds like a 70s lounge.
Super !! ⭐⭐⭐⭐⭐
5:18 Not to sure about the toe on those joints.
That is NOT IPC class e for sure
This is IPC class 3. Excellent work!
@@Lukasz703check the first pin ! Its not IPC 3 for sure!
@@Solder_it there is a very nice heel and toe. Imo this od IPC 3. Why u think its not?
@@Solder_ittop right pin is the worst
After finishing solder do you clean with ipa or other specified chemical like chemtronics flux off?
Lint-free IPA wipes are best used to clean off flux residues after soldering
Make 1 video with 0201 resistor 😅
What flux are you using,and solder tip?
2x thermall stress.
Some components like big mlcc's, didnt allowed to use soldering iron.
leadfree solder right....looks like crap.
Leaded solder always flows better
Это Вы просто не умеете паять...
Nothing new for me to see. I’ve done it all.
For you,not for many people like me
Thanks for you comment anyway God bless you
Have a good day
@@ingridramirez4436, pardon me if I offended you.
@J Mikronis
No you pardon my ignorance
I am working in QC by luck
I am being working at my job 17 years I was in production for 10 years and then they needed a person in QC since I am always care about my job they decide to put me in that position. But now we are going to have classes and then test about IPC fron out side . I am nerves I used the book a lot but since my English is not that good I am afraid.
Terminologies words that I never used.
