For reflow, bump up your profile as hot as you can go as allowed by your paste manufacturer will allow. If you can change solder paste without too much red tape, several solder paste manufacturers make a transitional paste designed for mix of lead a

We noticed unsufficient soldering on some 0805 chips located between pins from a plastic bloc connector . All chips are soldered with 45� angle. Flux quantity , preheating , contact time and PCB quality was checked. Do you know any international stan

No, raising the solder pot temperature to 800*F will not affect affect your solder alloy. We expect that you had a fairly high level of intermetallic compound generation, but most of that would be included in the fairly high dross generation that ha

We are having problems with a specific lot of boards wave soldering. I need a way to prove the boards are bad, does anyone know a way to verify the amount of OSP coating on a board, or a company I can get to do it for me? I am using PBfree solder of

I think the BLT solder joints look very shiny for no-lead. We are getting very good top side solder with ours though. They look like this. - Gold Enig plating - Alpha EF-6100 Flux - SAC305 - Preheat topside temperatures at 110 to 120C

Hi Radek, Thanks for your reply. I use this flux with manual soldering process for the product. Is this flux suitable for manual soldering? or it is only for wave soldering? I have sent the board for analysis, and the report shown that the white res

The design of this machine makes it difficult to lift the pump out to clean as often as it probably should be. We are seeing dross on the solder source side of the boards. Does putting wax in the solder pot help reduce the dross? If it does help, wh

Using common wire size and through hole diameter, we'd expect that the wave solder process would completely fill the through hole and that you wouldn't need to get involved in providing stencil openings, pasting the through hole or reflowing the jump

Hi, I have a design were power supply multi strand wire (AWG18) are soldered directly on the pcb (thru-hole) by wave soldering process. I don't have any ferrule on the wire. I would like to know if the IPC standard allow this for class 3 assembly

Per IPC-A-610D: Target is 100% vertical fill but 75% vertical fill is acceptable for Class 1,2,3. Only needing 75% fill of the barrel when soldering plate through on an 0.093" thick board with our selective solder has been a life saver at times.
