Rev. 02.10.B Manual stencil printer SD360‐U August 2018 IMPORTANT SAFETY INSTRUCTIONS Machine location: Do not use the printer outdoors! The printer is developed to be installed on a flat, dry surface. This surface or table must be capable of carrying a weight of at least 15 Kg (excl. The force used to spread the paste). The printer should be used with temperatures between 15 and 25 degrees Celsius. Only use the printer in well ventilated rooms. During the printing process the flux will release some gasses. These gasses released by the flux can be unhealthy, please follow the safety instructions of your paste supplier. Regular use: The printer is developed for printing paste on PCBs only. Do not use the printer for printing on food, animals or any other materials. You will void the warranty if you do not follow these instructions. When used for anything other than printing paste on PCBs you will void the warranty! Introduction Remark Pictures in this manual can be different than the actual model you’ve purchased. They are only meant to explain the printers’ use and function. The SD360‐U stencil printer is designed to put solder paste on PBCs with a stencil. A stencil is a thin metal sheet which has holes matching the position of the pads located on the PCBs. Unlike other stencil printer brands, the SD360‐U has unique features for user friendly handling of stencils and PCBs. Some of the features included: Lifting the stencil horizontally before opening the frame Stencils do not require mounting holes. Fixing a stencil is fast, easy and requires no heating of the stencil. Positioning of PCBs is simple but effective. You may use the stencil printer for single, as well as double sided PCBs. Even if there are already components on one side! Setting up the stencil printer This machine is produced and packed with special care to deliver you the best quality product ...

Rev. 02.10.B Manual stencil printer SD360‐U August 2018 Getting started Installing the stencil 1. Set the Z‐axis elevator lever (9) to the UP position. 2. Loosen the Y‐axis alignment or stencil tensioner. (10) 3. Loosen the stencil size adjustment. (5) 4. Unscrew the eight screws of the stencil frame. (A) 5. Place the stencil in the first stencil holder (near the Y‐axis alignments.) (10) 6. Tighten the four screws. 7. Shift the upper stencil holder to the lower stencil holder so the stencil will fit. 8. Tighten the four screws. 9. Press the stencil size adjustments against the upper stencil holder and tighten the screws. 10. Tighten the stencil tensioner up to the half of the length. (10) 11. Lift up the stencil frame. Installing the first PCB 1. Open the printer. (picture A) 2. Place the PCB roughly in its position with 4 to 6 magnetic placeholders. 3. For large boards use the two magnetic points and place them in the middle of the PCB. 4. Place the transparent outline sheet over the PCB and close the printer. (picture B) 5. Set the Z‐axis elevator lever (9) to the DOWN position. 6.

Remove the outline sheet without moving the PCB and close the printer. (picture B) 9. Use the bottom and top height controls (6) to bring the stencil just above the PCB. The less space between the stencil and PCB, the better. 10. Use the X‐ and Y‐axis for small adjustments to align the stencil holes and PCB pads. 11. Set the Z‐axis elevator lever (9) to the UP position. 12. Your printer is now ready for printing! Operating the stencil printer Once the installation has been completed following the steps described above, it is easy to place successive PCBs on the magnetic placeholders. BUT BE CAREFULL Due to the fact that no PCB is exactly the same, it is advisable to check if the PCB pads still exactly match the stencil holes before each print. Let’s get started! 1. Place a PCB on the magnetic place holders and close the printer as described before. Check if the holes and pads are still aligned. Fix any alignment issues as needed and continue with step 2. 2. Bring the Z‐axis elevator lever (9) to the DOWN position. 3. Put the solder paste on the far side of the stencil with a spatula. Make sure the solder paste is applied over the full width of the stencil cut‐outs. 4. Place the squeegee behind the solder paste under a 45‐60 degree angle and in a zigzagging motion while applying a little pressure, move the squeegee to the near side of the stencil. Make sure that all the holes in the stencil are filled with solder paste. 5. Remove the remaining paste at the end of the stencil with the squeegee. 6. Bring the Z‐axis elevator lever (9) to the UP position. 7.
