Hello (Amateur solderings 😒 )
I have by time often come up with some SMDs missing and thinking that I could finally do something about those.
I need inspiration on buying a SMD soldering iron and multiple needle small tips\heads.
What brands and models do you use ?
Do I have to pay that 100-200euros for a "station style model" or will some eBay's budget sharp tipped 60W be good enough for 1st timer ?
I have used 10euro irons: LUX-tools 30W and 60W(German China brands).
- They eat tips I can use the tip only one time and after the one use the tip's "silver coating" is gone, color is turned black orange and the tip's performance is really poor after that happens.
Weller's battery operated AA cordless 20euro iron was really bad it was like 10W. I trashed it.
I buy also:
- Tiny 0.5mm diameter unleaded solder. D=0.020" and/or 0.015".
- 1mm braided solder wick.
I went with 3 separate stations, slodering, desoldering and hotair and don't regret. If you want to buy one all-in-one station that is at least average, then you have to pay more. This is how it works.
1. for soldering - 60w (I guess) solomon/pensol. my model is SL30ESD but can be found under different names in other countries
+ no issues regarding operation, I got it it like 4+ years using same ceramic insert and same tips set
+ tips are cheap, longlasting, 5 or 6 shapes, station holds temperature with small fluctuations only
+ ceramic heater
+ price is good
- heats up about a minute
- to change tip you have to wait until it cools down to unscrew it (weird)
- for some situation it may be still to weak when it comes to heat transfer
If you are a DIY person then on ebay you can find a thermocouple set to make your own soldering station, just need a soldering head (hakko?) with a tip + case.
2. for desoldering I use ZD985:
+ not very expensive
+ does the job done
- slow (like really really slow) to heat up
- tips are not longlasting. If you would like to desolder components from like 10 motherboards with the same tip, then good luck, chances are you will burn the joints eventually as the tip will degrade with use. This does not mean it's usless, you just need to have few spares and check its condition before any longer repair. Fortunately they are cheap.
- pistoll gets clogged with some solder gunk over time, but the long skewer in 3 sizes is provided in a set, so a little plumbing skills are required 😎
- some early models had earth/ground wire swapped in cable provided and it caused LCD to burn.The cable is like the one from PC PSU, so check the marking before plugging. Mine was ok. Just change cables and that's it.
3. for hot air SMD stuff I use Quick DW861
+ this thing is great
+ not super cheap, but fairly good price
+ quiet, reliable
+ 3 channels with temperature
+ tips are available (4? is available in a box), but some may be quite expensive (like some models for BGA or big size QFP packages)
- I havent't found yet, best buy so far
For soldering I use standard solder (Pb) wire and I guess for hobbyst stuff you don't need anything special. For BGA this is different story. I bought once from ebay a low temperature melting solder for tricky situations when you cannot afford to heat up components too much. A word of warning with hot air, buy a few reels of kapton tape - this makes your life easier and less stressful. Hope that helps a bit.
