Hello Bachman. SAC305 is the most common lead-free solder alloy, not only for wave soldering but also selective. Most of our selective customers (especially automotive) are using SAC305. What is more important than the alloy to consider is the flux

No clean pastes leave more flux residues. These can result in void formation and inhibtion of underfill curing. Selection of an underfill that is compatible with the flux residue is important. One company that has written about the effect of flux

You're correct, for every dumpster full of paper written about solder, there's a sentance written about fluxes. There's dribs and drabs about fluxes in most of the soldering books [ie, Manko, Klein-Wassink, Judd, Strauss, etc] and most of that is ve

I run two different waves here one with SAC305 with aqueous flux the other with SN100C and No clean flux. Does anyone see any issues with running product through either machine of course after changing the Flux type? I also only use SAC305 alloy for

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from

Another thought, why not contact a flux supplier that is able to give you the background information you seek? For instance: Daniel Werkhoven; Interflux Electronics/Belgium [ http://www.interflux-electronics.com ] [We have no relationship, nor rec

Solder balls with wave soldering can have different causes. The two most important are the solderresist and the flux. I have similar problems, after changes the flux type 90% off all solderballs are gone. KR, Joris Groot koerkamp

I would say no, unless your machine is in extremeconditions. You may want to check your flux / preheat out as well. If you are leaving a lot of flux on the board at wave, it may be boiling - which can cause solder balls.

Hi there! If they are just standard headers there's a company called Teka that makes headers and socket headers with solder preforms in them. They call it "Solder Bearing Lead Technology" You can drop them in the board and reflow them just like SMT p

U may check your profile ramp rate. The flux may evporated and look like cold joint
