94% Pad design for SMD Bottomside wave soldering - 5/9/01 -
... be made more reliable by decreasing the pad size. Wave soldering puts a tremendous amount of solder, relative to reflowed connections, on each end of the ceramic chunks that comprise SMT resistors and capacitors. Wave soldering puts more solder on these connections for two reasons: 1 There is more solder available to form the connection in wave soldering than reflow soldering. 2 Components are stood-off the board more in wave soldering than reflow soldering as a result of using adhesives to ...

94% Lead Free Wave Soldering - 7/22/04 -
... more closely than with SnPb. Wave Soldering Equipment * Most modern wave solder machines can provide the necessary heat (preheat and wave) for lead-free soldering. * Nitrogen blanket may be required, depending upon the alloy selected. * High-tin alloys rapidly dissolve the materials often used in wave solder equipment. SS pots, nozzles, impellers, etc will need to be replaced with cast iron, titanium, or a special coating. * Wave soldering equipment manufacturers have had success using a ...

94% Through-hole/SM mix - 10/15/01 -
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 ...

91% Blowholes during wave soldering - 9/11/07 -
... one would take for other types of wave solder defects, such as bridges or insufficients. About your comments on wave soldering as an artform, no doubt you are an experienced and very good quality engineer, so that your instincts lead you to control the wave solder process. Yet behind what you have termed an artform is both knowledge and measurable, quantifiable data. This can be captured and responded to methodically, thus demystifying the wave solder process. Such an approach is certainly ...

91% smt components vs. wave solder - 11/11/02 -
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 ...

... 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 ...

90% Immersion white tin wave soldering problem - 12/16/05 -
Immersion white tin wave soldering problem Anyone have problems wave soldering white tin finish? We are an ems and our customer provides us the pcb's. SMT and TH components on the board. SMT is fine but when we wave solder, wetting to top side is very poor (solder only flows half way up). We tried increasing and decreasing pre-heat, increasing flow rate on spray fluxer, increasing pot temp, decreasing conveyer speed, hand spraying the flux, all with no success to get solder to flow all the way ...

90% Wave Soldering 14 and 16 Pin SOICs - 3/9/99 -
Wave Soldering 14 and 16 Pin SOICs We will wave solder a board with SOIC14 and SOIC16 parts on the bottom. It has been difficult to find any specific wave solder process recommendations from manufacturers of the SOICs. The pad geometry utilizes theiving pads on both sides to reduce bridging. Can anyone share their experience in setting up the wave solder process to avoid thermal damage to the part. What is the optimal temperature profile for wave soldering such components? My optimal profile is ...

89% 0402 wave soldering - 1/12/09 -
0402 wave soldering Hi Stefano, Although your concept of Wave soldering such devices is possible, I would look at an alternate solution. An easier way would be to Reflow solder all Bottom side SMD components with solder paste, followed by wave soldering for only through hole components using a customized "selective wave soldering pallet". One of the materials I could recommend for making such pallet is Durastone, but there could be some others as well. I had designed such pallets for our in ...

89% Wave Soldering with or w/o Nitrogen - 3/12/02 -
Wave Soldering with or w/o Nitrogen I'd speculate that the properties of a well formed solder connection processed in air and N2 are indistinguishable. Then again, the pitch is that N2 gives a wider process window, especially for NC flux-types. In the SMTnet Library look for: ?Optimizing the Wave Soldering Process with Hot Nitrogen Knives" Chrys Shea, Siemens, & Gary Shipe, Air Products In the SMTA Knowledgebase look for: ?Inerting The Wave Soldering Process With Membrane-Generated Nitrogen ...

88% What is delta t? - 10/25/07 -
... medium. In reflow, we often speak more of ramp rates, which are derived from delta T's. Basically, your ramp rate is your Change in Temperature/Change in Time. DELTA T in WAVE soldering is the temperature difference between your last preheat, to when your PCB assembly hits the wave solder. Rule of thumb in wave soldering...reduce your Delta T as much as possible before it hits the molten solder. Rule of thumb is 100?C. This can be accomplished from either increase of preheat, decrease of ...
