Steve, I wave solder most if not all our boards with selective wave pallets. I did not catch if the solder balls were on top of the board or on the bottom but that will make a difference on what to do to get rid of them. Pallets are good and bad. On

Hello Greg, Glad to hear your success with the SACX0307 copy. By the way, does the P mean it contains phosphorus? Does yours also contain bismuth like the SACX0307 (according to their plumbing solder patent for X0307)? In response to your discussion

First, your primary side component pads should be designed according to SM-782A, "Surface Mount design & Land Pattern Standard". Next if you did that and your secondary side component pads are the same size as your primary side components, your diff

I have checked pot temperature in different parts of solder pot and it looks like it is correct (250C). I have also lowered solder pot temperature and removed copper from the surface of the solder pot (operation repeated couple times). There is still

Is 260 degrees C / 500 degrees F the optimum temperature for wave soldering ?

Thanks for your advice. I've tried setting the temperature up and even measuring the temperature at the wave itself but had no luck at all. I've also tried using temperatures going from 245 ºC up to 260 ºC. The amount of flux was adjusted as well a

If you will place a temperature strip on the board during wave soldering process you will get a max of 210 F or 98.8 C which is normal on the standard wave temperature. The problem on the 10% solder on the TH via hole can be caused by insufficient fl

Per our staff here at ACI......... Higher Temperatures maybe necessary to achieve good solder process results. The alloy formed when HASL coating protects the copper is the same as that when OSP provide protection. Temperatures may be increased to im

Correct preheating of the assembly is critical. Check with your flux manufacturer regarding the recommended topside pcb temperature as it enters the first wave. It is important that this temperature be achieved without burning the flux on the bottom
