I. SUMMARY A. INTRODUCTION In the past, it was customary to prepare solder paste in the following manner: Remove the paste from the refrigerator. Allow it to come to room temperature. Mix the paste to an even consistency. Clean up the mixing tool. The SPS-2 allows you to accomplish these tasks in one step, and without even opening the jar. Since the process is automated, results are not dependent upon individual users, and since the process happens within a closed jar, undue oxidation of the solder paste is prevented. B. FEATURES ● The SPS-1 is an efficient mixer. ● The SPS-1 uses off the shelf, airtight containers so oxidation and humidity during preparation are no longer a concern. ● Automated operation assures gentile softening, and unlike hand mixing, provides even consistency. ● From refrigerator to screen printing in just fifteen (15) minutes. ● Centrifuge is self-balancing and has an off-balance safety detector C.

Pseudo-Planetary Motion

The SPS-1 employs a pseudo-planetary motion where the solder paste cartridges rotate slowly at either ends of an arm which spins rapidly. The resulting centrifugal force causes the solder paste within the cartridge to repeatedly fold over itself thereby mixing and softening the paste.

Start Switch: After setting the timer, press START SWITCH to start mixing. 4. Timer Setting Switch: This now sets the desired mixing time. Turning it clockwise will increase the time displayed on the LED. Turning counter-clockwise will decrease time. There is rollover at "99" and "00" minutes. A series of beeps will sound when the display shows "00". 5. Timer LED Display: This display shows the set time and during mixing, the time remaining. 6. Ready LED: LED will light when the cover is unlocked and it is possible to open. 7. Door Lock LED: LED indicates that the door lock has been activated. The "Ready LED" and the "Door Lock LED" will not be on at the same time. 8. Balance Error LED: This lights when the centrifuge becomes unbalanced. At this time, the mixing will STOP. 9. In Rotation LED: This is the decimal point of the timer LED. It will flash during the mixing process. It is labeled, "RUN". 10. Handle: To open the top cover, once unlocked. Do NOT use this handle for carrying or moving the SPS unit. There are recesses at the lower sides of the SPS unit for these purposes. 11. Battery Box: Four (4) AA batteries are out here for the auto-balancer. If the SPS-1 is not going to be used for an extended period, then the battery connector should be removed. 12. Housing: The solder paste jar is placed her and secured with the clamp. The housing is a special size to accommodate a particular. Due to this, the SPS unit must be ordered with this certain jar in mind. 13. Clamp: Keeps the solder paste jar inside of the housing.

II. USAGE A. OPERATION 1. Turn On the power switch on the top panel. The timer LED will light, the door lock LED will illuminate and a series of beeps will sound. 2. 30 seconds later, the door lock LED will turn off, the ready LED will light, and the door lock releases. The top cover may now be opened. 3. Place solder paste jar into housing. Make sure it fits snugly and secure it in place with the clamp.

You may find that the housing is positioned in a way that inserting the solder jar difficult, -in that case, gently spin the centrifuge so that the housing will align for the solder jar. This may take several revolutions of the centrifuge. Also, if the clamp cannot be opened or closed because of obstructions, carefully rotate the centrifuge so that it aligns with ample space.

4. Close the cover. 5. Use the timer setting switch to dial the desired mixing time. Clockwise will INCREASE the time,

counter-clockwise will DECREASE the time. The time setting will roll over at "99" and "00". 6. Press the start switch. The door lock will engage, the door lock LED will illuminate and the centrifuge will start to spin. 7. After two and a half minutes, the rotational speed of the centrifuge will increase. If the centrifuge

has not balanced at this time, the balance error LED will illuminate. A series of beeps will sound and the mixing will stop. Inspect the centrifuge, if nothing is wrong, then continue from step #4.

8. If you press the stop switch or the timer has counted down to "00", beeps will sound and the centrifuge will stop rotating. After it completely stops, the door lock will release, the ready LED

will illuminate and the door lock LED will go out. 9. Use the handle to open the cover. Release the clamp and remove the solder jar.

GUIDELINES: 1. When placing the solder jar into the housing, REMEMBER TO CLAMP IT INTO PLACE.

Failure to do so may cause the jar to fly out of the housing during mixing, resulting damage to the centrifuge. Also, the clamp will damage the inside of the SPS unit, in addition to the centrifuge. Bear in mind that there are no sensors to indicate that the clamp is secured.

2. Even though there is a 10 second delay for the door lock, it may release before the centrifuge has

stopped spinning. In this case, look through the window on the cover and verify that the rotation has stopped before opening.

3. Also, if the SPS unit seems to vibrate excessively or seems to be making an unfamiliar sound, press

the stop switch and inspect the inside, in addition to the centrifuge of the SPS series. 4. The SPS unit should be placed on a firm, leveled, and stable surface. 5. The SPS series has several safety devices built-in. DO NOT ATTEMPT TO OVERRIDE

THESE DEVICES. You will VOID the warranty and jeopardize your own safety as well as others.

C. BATTERY REPLACEMENT Battery replacement is typically every six (6) months. This is when using alkaline batteries and the SPS-1 is operation 5 times a day. The batteries are located in the battery box, atop the centrifuge. 1. Open the top cover and remove one of the screws holding the band across the batteries. 2. Swing the band over to one side to allow access to the batteries. 3. Remove the old batteries and dispose of them properly. 4. If the replacement batteries are less than alkaline type, expect less than six (6) moths service life. If

of higher quality, then a longer life. 5. Observe the correct polarity when replacing the batteries. The polarity is marked in the battery

holder. 6. Swing the band back over the batteries and install the screw for a snug fit. D. BELT REPLACEMENT On the occasion that the belt within the centrifuge becomes brittle, cracked, or even breaks, it should be replaced. Please follow these instructions for replacement:

APPENDIX A. Theory Many automated solder paste mixers have been developed. Some use a rotating paddle, a few shake the solder paste, and others subject the paste to centrifugal force. The SPS series, in effect does all of this without even opening the solder paste jar. The easiest way to understand how the SPS series works, is to observe its operation from several viewpoints. Imagine yourself reduced in size and sitting in the center of the centrifuge of the unit. As the centrifuge turns, you feel no centrifugal force but you can watch the housing containing the solder jar spin around in front of you. As you walk away from the center, you will feel the centrifugal force become greater and greater. Standing in front of the spinning housing, you feel the same force that is acting upon the solder paste inside the jar. Let's remove the solder paste and put you inside of the jar. The centrifugal force causes you to be pressed to the wall. Since the jar is also spinning, you begin to tumble -much like clothes in a dryer. Take into consideration that the housing is mounted at an angle, and so as you tumble, you find yourself rolling towards the top, and then toward the bottom. What is happening, is that you are being mixed and shaken up at the same time. This is what happens to solder paste in the SPS series. In addition, since the solder paste is so viscous, this mixing and shaking motion tends to raise its temperature. A solder paste put into the SPS series can be mixed, shaken and heated, all at the same time.

MATHEMATICAL DATA: For F = Force acting upon the solder paste for an area of one square centimeter n = rotational speed of the solder paste jar ρ = density of the solder paste r = radius of rotation AND F = ρ • r • ω • ω • = 4 • π • π • n • n • ρ • r (dyn/sqcm) . . . (1) If solder paste were to be mixed with a narrow blade, where a 1 kg force was applied with a 2 cm wide by 5 cm long blade: The contact area S = 2.5 = 10 (sqcm) .................................................................. (2) The stress acting over this area: σ = F/S = 1 (kgf)/10 (sqcm) = 0.1 (kgf/sqcm) .........
