does anyone know of a way to reflow thru hole components at the same time as smt components. i would really appreciate it someone could give me some information on this or maybee tell me where i can get some info on this application. thanks in advan

You should only need to mix in thinner if your formulation changes. You will need to check the specific gravity of your flux. You can do this by using a hydrometer. Contact your flux supplier for their advice.

We'd guess thinner, but more importantly, what does the formulator of your flux say?

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

Hi All I received some advice 1) use Flux with Thinner 2) use Flux with Water. Which one is better for my wave sodlering? The type of Flux is watersoluble.

Dear Dave Thanks for your advice.I dun know why flux can't use alone w/o adding other solvents. is it neccessary? Now, our flux density is 0.88. By the way, we use Hi Grade Flux 1080.

use thinner and contact your supplier about it. the guy that advised you to use water is probably from your competitor. LOL

This has come up a number of times recently and a search for intrusive reflow or pin in hole reflow will reveal several threads. Also a good resource is the link below. From what has been stated on many of these forums and my own pre-production tes
