Considerations are: * If the nonwetting is component lot specific, the could be solderability issues with that lot. * If the nonwetting is is a broader based component issue, the solderability protection on the component may require a different reflo

I have another question: Does the slope of the conveyor is an important parameter in the solder joint quality? What is the standard in degree? Does that parameter can resolve my problem of partial fulling hole (between 50 and 75%)?

If you don't have Plated through holes you will not get any hole fill! There is nothing for the solder to wet to. Problem solved? Russ

Rapid heating of solder caused solder underneath surface to expand and become pressurized. Check to see if power cycles on and off during warm up. A slower rate of of climb should help.

Hi, We are looking for the best method to clean dried solder paste and residue from screen printers and wave solder equipment. What do you use for vacuuming? For breathing protection?

I ran into this yesterday. Seems some designer decided to not solder resist the via's on the solder side. Then the assembly went over the wave solder in a universal fixture. Not an ideal situation.

Hi All, I have to solder a device with platinum clad nickel leads to a PCB. I am having a hard time getting solder to flow on to the leads. Are there special proceedures that I need to follow because of the platinum or am I just dealing with contamin

Agreed. In my experience you will not wet solder to: Platinum Iron Constantine Tungsten Carbide titanium Chromalloy allomega alloy 303, 304 ...and the list goes on and on. You will either need to weld or braze. These are high temperature prcesses

1.Can anyone explain to me what is the clean and non clean solder? 2.What is the standard solder paste height spec for stencils 4mils,5mils and 6mils? 3.Whatis the meaning for ROHS?

is there any relation between solder paste viscosity and the length of time the solder paste being used in the machine? pls advice....
