I'm looking for a preheater for hand soldering, but haven't used one before so I could use some advice. Does anyone have any preferred styles or brands? Is there anything in particular that I should either look for or should avoid? I've seen prices r

Thank you for the advice. I have the same concerns with applying that much heat from a single point, so I will probably go with a Zephyrtronics preheater. Tom

We had the same problem with one of our boards with ground planes so that it required preheat using a hotplate before hand soldering. Then I learned about the Metcal MX-5000 series soldering irons. I was skeptical at first but we can now solder the s

Depending on your requirements, you could range from a hair dryer, heat gun, toaster oven, hot plate, on up to digitally controlled surfaces and convective systems. You'll have to gauge for yourself whether you are just trying to add some heat energy

My own preference in this arena is towards the forced air convection style preheat, the key being the forced air. Radiant preheat is too slow for some, and IR preheat can have other issues that convection (or radiant) will not. Zephyrtronics has bee

Thank you for the advice Hegemon. I agree that there is a wide range of options available. I'm looking for something that can give me some repeatable surface temp control, is easy to work with, and has at least decent build quality. I don't necessari

hi, NEMI recommends separate solders for reflow sodlering and wave soldering. Reflow soldering- Sn-3.9Ag-0.7Cu Wave sodlering- Sn-0.7CU Wavesoldering- Sn-0.7Ag What will happen if a mixed technolgy PCb board containing both through hole and surface

From my understanding (and I am not a metalurgist)Most Lead free solders can be intercahngeable.The alloy created should be stable. The issue is if you add Leaded solder to the joint. Obviously, research and testing is still pending. cal

If you are talking about reflowing surfacemount on the solder side of the assembly, that is accomplished by gluing the smt components to the bottom of the board. I recomend that you use a chip wave in conjuction with the normal wave to get the best r

This recipe is nice for leaded soldering. The time above liquidous plus 20*C is too short for mixed alloy soldering. Remember all that nonleaded stuff that you add to the solder acts to increase the liquidous temperature of the alloy. Try slowing
