Understanding the Cleaning Process for Automatic Stencil PrintersEd NaussSr. Sales / Applications EngineerThe automatic stencil wiper –first line of defense •The Printing process and why we need to focus on the wiping function•Frequency of wiping•Wiping options•Wiper profiles•Event driven wiping•Advanced options•Materials –Paper•Materials –Solvent•Preventive maintenance•Random stuffPrimary goal of the printing machineTo print or place an exact amount of material in a precise location.Simply -Align the board to the stencil•Solder Paste•Adhesives•Flux•Solder Spheres•Thick FilmHowever the printing processhas become much more thanthat…….To address defects and yield –the printing process has the largest impactSMT Defects:•Printing process is the major cause for yield loss (50-75%)Auto stencil wiping is the critical tool for addressing these defects.Printing Process is critical to success:•Confirmed by 86% of SMT industry(Value in Use Survey 2016)Yield & Throughput influence up to

holding the deposit to the stencil walls.The paste near the wall stretches and snaps.StencilPCBPCB PadPaste up and sticks to both the stencil walls and thepads.Depending on the pad wall area ratio, a portion of the paste will release to the PCB, while some will stay in theapertureSome paste may also stick to bottom of stencil due tostringing, bad gasketing or pump outWhy do we wipe?•Gasketing•How often we wipe is a direct result of how well the board and stencil are positioned and sealed •Contributors of gasketing issues:•Incorrect or varied board thickness•Variation of mask thickness•Encroachment of mask on pads•Pads recessed below mask•Nomenclature /silk screens•HASL•Board warpage•Bar code labels•Damaged or worn stencils•Loss of stencil tension•Insufficient tooling / support•Board holding interference•Vacuum•Squeegee over pressure•Mismatch of aperture to ball size•Machine contaminationIDEAL STENCILCONDITIONNo unwantedpaste insideapertures or onbottom surface

wallgeometry andtopographyAlloyRelease coatings inaperture or on surfaceFoilThickness(Area Ratio)Powder SizeDrynessTaking the guess work out of Frequency•Most customers “Guesstimate” the wiper frequency•Apply same frequency number to each individual printer program•Issue: wiping frequency is not linear•Under-wiping•Allow paste to build up on bottom of stencil•Solder balls, bridging poor gasketing•Allows paste to build up in apertures resulting in clogging and decreased material transfer •Over-wiping•Elimination of flux that acts like lubricant during material transfer•Excess paper and solvent consumption•Cycle time hit•Simple DOE can determine a starting point for wiping•Use of onboard Inspection or down stream SPI is another tool to determine or adjust frequencyDetermining Wiper Frequency Manually•Inspect the stencil and ensure the stencil is clean•Print 1 board•Jog vision system to inspect stencil bottom surface for paste residue (Squeeze Out)•If there is no evidence of Squeeze Out, print another 1-2 boards•Repeat this until you see Squeeze OutSolder paste residuebridging the gaps betweenthe aperturesClean StencilSubtract 1 -2 prints from the determined number of prints for your “wipe frequency”Stencil after a wiper cycleWipe Types•Dry Wipe –most common used –addresses the solder balls on the bottom of the stencil caused by bleed-out from the aperture •Vacuum Wipe –address the aperture to remove paste and address clogging of the aperture•Solvent wipe –used to address the flux on the bottom of the stencilWipe frequency•>15 –excellent gasketing –aperture sizes are not challenging•10-15 –good gasketing with the occasional anomaly•5-10 –Average wipe frequency –some challenging apertures –some gasketing issues•2-5 –Poor gasketing –mismatch of materials –stencil design issues –very challenging components•1-each print –something is wrong -requiring a wipe after every print –micro components –pushing envelopeWiper profile –wipe 1Wiper profile –wipe 2Wiper profile –wipe 3Additional Parameters•Recent studies have shown a Vac/Vac/Dry or a Solvent/Vac/Vac/Dry wipe is most effective•The first vacuum wipe pulls solder from the aperture and forms stalactite's hanging from the apertureContinuous vs index mode•Continuous mode –advances the paper during wiper motion ensuring fresh paper is applied during the wipe –maximum paper consumption•Index mode –paper is advanced a pre-determined amount then is stationary during wiper motion –minimum paper consumption •Continuous has shown to clean better and prevent “snowplowing” of the paste particularly when vacuumingHop over•Used to address snowplow effect –retracts plenum and moves over end pointOvertravel•Wipe stroke pre-determined by squeegee stroke –allows extension of stroke –eliminates contamination of gold fingers if present Wiper speed•Recommended speed of wipe or solvent stroke –2 Inch/second•Recommended speed of Vacuum stroke –1 inch/secondEvent driven wiping•Key events that can trigger defects:•Pause in printing•First 1-4 prints•Additional paste added•Custom Wipes to target specific events in the printer •Pause in printing•Based on thixotropic index of paste•Recommend a medium plus wipe•Kneed function•Squeeze out is the issue•Heavy on the dry wipe / no solvent•During paste dispense•Utilize printer window to do additional wipeWiper Paper•“Printers are only as good as the material that you put into it” –the same can be applied to the wiper•Using low-cost paper directly influences the wiper ability to clean the stencil•In general, there are two types of papers used in stencil wiping: papers made with synthetic fibers held together with glues (called binders), and papers made from a mix of natural and synthetic fibers that do not use glue.•The papers ability to absorb both the solder and solvents reflects on the cleanliness of the stencilGlue Binders•Synthetic fibers found in paper usually are polyester or rayon.•In general, about 30% of the paper’s weight is found in binders.•These papers have a harder surface, lower tensile strength, absorb less contamination and are less expensive than glue-less versions.•Cross-section microphotograph of polyester paper madewith binders, enlarged 200 times.•The fibers are coated with glue, making surfaces hard and unable toabsorb contamination.•Most empty space in the wipe has been filled with binders, reducing theability to pick up solder paste.Hydro-Entangling•Some paper is made using a process called “hydro-entangling”•This process involves laying raw fibers of polyester and cellulose onto a conveyor belt and intertwining the fibers with high-pressure jets of water•Heat and pressure then are used to dry the slurry into the proper configuration•Lacking glue, hydro-entangled papers have a softer feel•They are more absorbent, thicker and stronger than ordinary paper•The flat, rough cellulose fibers (thin, top layer) are highly absorbent, butweak and prone to lifting•The rounder polyester fibers (middle and bottom) provide structuralstrength and open space to pick up solder pasteHydro-Entangled, Single-Fiber Polymer• A new material consisting of a hydro-entangled, single-fiber polymer based on regenerated cellulose was developed.•This fabric, which is completely synthetic, contains no natural fibers or binders.•Under a microscope, the long, thin, hard fibers are identical and homogenous, giving the fabric an open structure.•The material is a pale, off-white color and highly absorbent.•The fabric scores well on the solder paste pick-up tests for non-liquidcontamination.•The fibers are smooth, consistent and hard.•The paper includes extensive voids and cavities to pick up solder paste.•There is no cellulose to rip or shred, or binders to dissolve and contaminate thestencil.Paper Compared (Dry Wipe Data Only)High End Paper Typical Paper Paper Using Glue Base Weight (oz/per yd²) 1.87 1.56 1.11 Tensile Strength (LB’s)293116

The benefits of using these products are clear: effective, shorter working times, enormous energy savings and a long useful life due to the high industrial quality.#49429 - 20” Cleaner#49430 - 22” Cleaner1. Bolt the two halves of the handle together with the two M6 x 60mm bolts, nylon nuts, and fourwashers.2. Connect the handle to the brackets on the deck with the two 55mm pins and rings.3. Apply thread sealant to the hose’s male threads and connect the hose to the swivel on thedeck.4. Again, using thread sealant, attach the in-line filter to the inlet of the gun.∙Check for damaged parts before each use. Carefully check that the surface cleaner will operate properly and perform its intended function. Replace damaged or worn parts immediately. Never operate the surface cleaner with a damaged part.1. Connect the inlet filter (D40014 on cleaner #49429; D40015 on #49430) to the FSC gun inlet.2. Connect the cleaner to a non-operating pressure washer.3. Turn the water on and open the valve. Open the trigger gun for flow of water through thenozzles. The nozzles must have flowing spray. If not, remove the tips, clean them, andreassemble the nozzles making sure that the groove of the nozzle is parallel to the spray bar.Use thread sealant when reinstalling the nozzles.4. Start the pressure washer. The surface cleaner is ready for operation.5. Walk slowly behind the machine, cleaning as you go. If striping occurs, slow down your pace.6. Periodically check the weep hole on the bottom of the swivel. Water will seep slowly; if watershoots out, stop and replace the seals. The swivel assembly can then be rebuilt.7. For maximum effectiveness, keep the spray tips clean. If the machine vibrates, stop and cleanthe spray tips.Inspect the cleaner after each use. Clean it and prepare it for the next use.∙Clean out any dirt or foreign material from under the housing and casters. Use a cloth or sponge to wash the surface cleaner and rinse with tap water.∙Check for loose parts and any damages.When storing the cleaner for an extended time, it’s best to drain as much water from the unit as possible. Disconnect the cleaner from the pump and stand the handle upright. Clamp the gun trigger open and let the water run out. Shop air can also be used in the gun inlet to force out the water.Store the unit in a dry, secure place out of the reach of children. Inspect the cleaner for good working condition prior to storage and before re-use.The surface cleaner does not require maintenance.Replacing the nozzles: Disconnect the FSC from the pump. Turn the FSC deck upside down andu se a 9/16” combination wrench to unscrew the nozzles. Do not let any debris fall into the open nozzle ports. Apply thread sealant to the new nozzle threads and thread into the nozzle ports. Tighten securely making sure the nozzle slot is parallel to the rotating arm.Replacing the hose: Disconnect the FSC from the pump. Unscrew the hose from the swivel using a suitable wrench. Thread the hose out of the hose guides on the handle.Loosen the two socket head cap screws on the gun using a 4mm allen wrench and slide the gun toward the end of the handle until the gun outlet with the hose is exposed. Disconnect the hose from the gun.The new hose can now be attached to the FSC. Use thread sealant on both hose threads and assemble the hose in the reverse order that it was disassembled.Replacing the swivel: Disconnect the FSC from the pump then disconnect the hose from the swivel. Use a 6mm allen wrench to loosen the socket head cap screw on the collar holding the swivel.The swivel can drop out of the bottom of the FSC deck. Remove the rotating arm using two wrenches. If a vice is handy, hold the rotating arm while turning the hex on the swivel outlet.Installing the new swivel in the FSC is the reverse process of removing the old one. Use only identical replacement parts with the cleaner. Parts that may be suitable for one tool may create a risk of injury when used with another tool. Never use a part that has a lower operating pressure than the tool itself.If the surface cleaner’s rotating arm is not spinning, ensure that the cleaner is not pressurized then tilt it upward so you can see the underside of the deck. If a nozzle is not spraying, it’s plugged and needs to be cleaned. The best way to unclog a plug is to remove the nozzle (9/16" wrench) and tap it on a hard surface (being careful not to damage the threads). It may be necessary to unclog the nozzle by running a thin wire through the tip.Seal the threads before replacing the nozzle. Teflon tape can often clog a nozzle so be sure tape does not get into the nozzle flow path. A light duty liquid or paste thread sealant is the best way to seal the threads (photo).∙For replacement parts and technical questions, please call Customer Service at 1-800-222-5381.∙Not all product components are available for replacement.
