Welke soldeerboutpunt moet ik gebruiken??

All of the soldering I've done to this point has been with through-hole components. Ik hoop op een bepaald moment in de toekomst over te stappen op enkele kleinere onderdelen voor opbouwmontage. I've got a Weller WES51 soldering station. There is a large number of ET series tips available. How do I choose the right tip for the components I'll be working with?

Jij kan, in feite, solder a 0.4mm pitch TQFP with a tip that spans several pins, such as the ETA you mention, but it takes a lot more skill and flux.If you’re doing mostly through-hole components, the ETA is perfectly fine.
I’m also doing SMT and very fine SMT work, so I also purchased the 0.030″ and 0.015″ conical tips. I use these under a microscope to do the 0.4mm (about 0.016″) pitch TQFP chips.
It is worthwhile getting the biggest chisel tip jij kan, ook, for the occasional need to deal with soldered heat sinks or parts soldered to ground planes or PCB heat sinks. These can pump all 40+ watts of your iron into the joint, allowing you to remove it without heating the component up too much.

Remark: Keep in mind that typical wet sponge tip cleaners can lower the tip’s temperature significantly, especially with the small tips.

How do you usually organize SMT parts during PCB assembly?

Suppose one is hand-assembling a board with many SMT components. Unlike THT, SMT components are often not labeled. How might one keep small (<100) quantities of such parts properly organized during assembly? Are there particular tools? Storage devices? Methods?

Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?

Last week, I visit a PCBA manufacturer for our new project. They not only introduce in-circuit tester but also flying probe tester, which can both ensure the quality level. Zo, Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?

Is aluminium foil a good substitute for kapon tape when soldering?

I want to desolder a tiny surface mount button from the motherboard of a phone. There are a lot of similarly tiny components surrounding it that I do not want to damage with heat from the soldering iron. Can I use aluminium foil in lieu of kapton tape to protect these components?
