... VOC free, as operation HOURS before wave solder I am considering moving my spray fluxer into a completely separate operation. Has anybody any comments of sraying VOC free flux on boards, then putting them in a drier/holding rack for possibly say overnight, then running them through wave solder? We are a low volume high mix shop using wave solder pallets. My original plan is to move the spray fluxer ahead of but inline and continuous with the wave solder conveyor, but then wondered maybe we could ...

Wave solder pallets Howdy all. The question that I have is on wave solder pallets. I'm getting quite a bit of flux trapped on the pcb where it contacts the wave solder pallet. I have an appropriate profile for my assemblies, The flux that i use is Kester 920-CXF No Clean, I wont be changing this flux for quite a while. How do all of you deal with flux being trapped under the wave solder pallet and not burning off? Thanks much. Jay Brower

Through-hole/SM mix Before this wave solder pallet salesman blather gets too far out-of-control, let�s stop for a minute. The three major approaches you have are: 1 SELECTIVE SOLDERING: Using: * Specialty wave soldering machine to solder specific areas of a board * Peculiar wave solder pallet on a standard wave solder machine to allow soldering specific areas, while block other areas from contact with the wave. 2 INTRUSIVE REFLOW: Using: * Paste printed on PTH pads and then reflow soldered ...

Wave Solder Fluxing We have installed a Sonoflux atomized mist fluxing unit (Model 9500)on our Future 1 wave solder machine. We are concerned that the retrofitting of this unit may not have been appropriate for our equipment, as we are now experiencing many problems with flux volume, uniform application, ect. As we understand it, the Sonoflux unit is to be place ahead of the wave solder machine, but because of the height of the conveyor on the Hollis machine, this is impossible. The technician ...

Wave solder pallets: lead and lead-free process Hi everybody, We have wave solder fixtures made of Durapol and multiple wave solder machines. Most likely we�ll use the same pallets for either tin-lead or lead-free solder for a while (of course after washing the pallets). Should we test the pallets for lead absorption before running them on lead-free solder? Any suggestions for labs to perform the test, if needed? Thanks a lot!! Hiram

Trouble with wave solder pallet Help!! Just got some new wave solder pallets in house. The pallets are 12 by 8 inches solid composite, with only two 1/2 inch by 1 inch spots cut out for the connectors. When they go over the wave, the solder wants to cling to the bottom of the pallet instead of falling back into the solder pot which causes molten solder to cascade over the side of the pot onto the bed of the wave solder machine. The fixture house says they have never heard of this before. Has ...

smt components vs. wave solder Like Mark, I'm guessing your problem is with SMT parts on the top side, the solder is re-melting and some of the parts are moving around during when the board is being wave soldered. When I had some training on thru hole wave soldering way back when, the target was 3 seconds of contact with solder when you wave solder. If the component leads have more than 3 seconds of contact, the top side of the board might get hot enough to reflow the solder joints on SMT parts ...

Solder Balls @ the Wave Solder Process Solder balls on the topside of our wave solder boards is a real issue. We have found that during the wave solder process, solder will enter through the via holes in the form of solder balls. It seems to be related to flux captured in the vias and once the wave hits there is a splattering effect. The problem seems to be greater at times. I have asked design for some options with these plated through holes but haven't found any. The vias are used as test ...

Cleanning no clean residu Bruno The real question about your troop using Kester 951 wave solder flux on boards is: how is the flux applied and controlled. See, when you apply this flux with your wave solder fluxer, it is ideally applied in a metered fashion with your fluxer. Next, as the board is processed through the machine, it brings the flux to the proper activation temperature. These two actions, precise amount and proper heater, are assumed conditions of low residue soldering. In other ...

It's around 200 Deg. F of preheat, and then immersed in 480 to 500 deg. F of molten solder for about 3-5 seconds (depending on your configuration and profile). Components and Boards undergoing this more than twice doesn't sound appealing. I doubt any studies have been done on this, and I'm sure there's a ...
